When Sakuragaoka High School's Light Music Club (''keiongaku-bu'') is about to be disbanded with all of its members graduating, Ritsu Tainaka seizes her chance to become a club president without actually being elected and drags her shy friend Mio Akiyama for the ride. They recruit two more students in order to meet the minimum member requirement: Tsumugi Kotobuki, a wealthy blonde who was looking for another club, and Yui Hirasawa, an airheaded girl whom they tempt with numerous sweet things until she agrees to join.

With their new band formed, the four come to a sudden realization: none of them can play an instrument ''that'' well. The group sets off to improve their musical skills, with plenty of SliceOfLife cuteness along the way.

The show follows their progress as they get a club adviser (Sawako Yamanaka, an alumna of the light music club), decide on a band name (''Houkago''[[hottip:*:after-school]] ''Tea Time''), write their first original songs and finally perform on stage. Later, they recruit [[SixthRanger an additional guitarist]]: Azusa Nakano, a hard-working musician bewildered by the eccentric and relaxed attitudes of the other members.

The {{yonkoma}} manga by Kakifly, serialized in the same magazine as ''HidamariSketch'', was turned into an anime by KyotoAnimation in the spring season of 2009. The show proved to be a runaway success, with the [[AnimeThemeSong opening]] and [[EndingTheme ending themes]] [[http://www.youtube.com/watch?v=G106ZvylNoc topping out at #1 and #2 in the Japanese music charts as well.]] The manga has been licensed for a future English release by Yen Press. The second season, ''K-On!!'' (note the two exclamation points), aired in the spring of 2010 for 26 more episodes. [[http://www.animenewsnetwork.com/news/2010-09-28/k-on-gets-film-green-lit A film]] was announced after the second season ended; it was released on December 3, 2011.

In 2010, Creator/BandaiEntertainment [[http://www.animenewsnetwork.com/news/2010-07-01/bandai-entertainment-adds-k-on-anime announced]] that they had licensed the first season in the US and Canada. In August of that year, they announced they would dub it. The first volume of the English dub was released on April 26, 2011. In early 2012, Creator/SentaiFilmworks licensed the second season, complete with the same dub cast. The first season is licensed to MangaEntertainment in the UK, and both seasons (as well as the movie) are distributed by Creator/MadmanEntertainment in Australia and New Zealand. In 2012, Sentai Filmworks announced they acquired the movie and will also dub that, releasing it in May 2013.

In 2011 a new [[http://www.animenewsnetwork.com/news/2011-02-07/k-on-manga-relaunches-in-manga-times-kirara-this-spring Manga]] was announced. It was later [[http://www.animenewsnetwork.co.uk/news/2011-03-06/k-on-manga-to-cover-college-high-school-in-2-mags announced]] that Kakifly is working on two new manga series. Then, this year, Kakily annouced that he will be ending the Restart! manga, and [[http://www.animenewsnetwork.com/news/2012-05-07/k-on-manga-second-run-to-end-in-june that]] the last volumes of it were released in Japan in late 2012. The last volumes of K-On! [[http://www.animenewsnetwork.com/news/2012-10-13/yen-press-adds-madoka-magica-spinoff-manga-last-k-on-volumes got licensed by Yen Press.]]

All characterization tropes are listed on the [[Characters/KOn character sheet]] subpage.

----
!!This series provides examples of:
[[foldercontrol]]

[[folder:A to D]]
* AbbeyRoadCrossing: Referenced when Mio fantasizes about a trip to England - the land of Rock Bands! (Apparently Mio really is a Classic Rock fan).
** The girls eventually get the opportunity to run across the actual crossing in TheMovie.
* TheAbridgedSeries:[[{{K-OnTheAbridgedSeries}} Here ya go!]]
* AbsurdlyPowerfulStudentCouncil:
** Subverted. When the third-year members all end up in the same class they think [[StudentCouncilPresident new president Nodoka]] might have arranged it, but it turned out she couldn't do anything of the sort and Sawako-sensei was actually responsible.
** Two sketch gags in manga Volume 3 show Sawako asking Nodoka for a raise, and the Cosplaying Principal asking her for a bigger role in the series.
* AdaptationExpansion: Compare any anime plot to the manga segment it was based on. Definitely for the better, though, and produces lots of good music and extra gags. This is even more pronounced in the second season.
* AllJustADream: Most of S2 E13 is like this.
* AliensStealCattle: According to the Occult Club.
* AlmaMaterSong: Which later got released in a [[RearrangeTheSong rock version]].
* AlphabeticalThemeNaming: Yui and Ui. The latter isn't exactly a common name.
* AmericanKirbyIsHardcore: The Yen Press published tankobon tend to include slightly more swearing than is true to the translation.
* AnachronicOrder: None of the second season's [[BakersDozen bonus episodes]] take place after the graduation in [[GrandFinale episode 24]]. The chronological order is 1-13, 27, 14-21, 25, 22, 26, 23-24. TheMovie is also set before/during graduation.
* AndYourRewardIsClothes: In the LicensedGame, ''K-On! Houkago Live!!''. Not bad, since those are the clothes that the girls wear in the anime.
* AnimalMotifs: There are small sculptures of "The Tortoise and the Hare" attached to the stair railing that leads up to the light music club's music room. Season 2, episode 8 makes it quite clear that the tortoise symbolizes Yui's slow development.\\
\\
These are actual architectural features of [[http://www46.tok2.com/home/arc/shiga/shiga_12.htm Toyosato Elementary School]] in Shiga Prefecture, which the high school in the anime was based on.
* ArtificialRiverbank: Yui lives close to one, and practices there during finals season for a talent show. It's one of the locations mentioned in the lyrics of "Tenshi ni Fureta yo!".\\
\\
The river bank, like a lot of depicted locations, is [[RealPlaceBackground based on a real site]], and can be found along the Takanogawa river flowing through Kyoto.
* ArtShift: A distinctive {{Chiaroscuro}} lighting scheme is used whenever a character is being dramatic (or just pretending to be. Others include:
** When Mugi [[YuriFangirl gets ideas]].
** During the SchoolFestival there is a MusicVideo [[ShowWithinAShow within a show]] that has a noticeably different style.
** There's a quite creepy one [[http://static.tvtropes.org/pmwiki/pub/images/k-on_nightmare_1762.jpg in the manga]]. Proving that no matter how light and fluffy a given media is, these days it'll contain at least ''some'' Nightmare Fuel.
** The characters break the Fourth Wall to explain that Sawako's eyes have drastically changed shape, color, and design in episode 5.
** Then there's the DVD specials, which are drawn in a [[StylisticSuck sketchy limited-animation style]] more reminiscent of ''CrayonShinChan''. [[{{Pun}} "K-On Shin-chan"]], perhaps?
** The anime closing/credits "music video" features the girls making mouth movements and facial expressions that deviate from the normal style of the show.
** Yui bursts into a slight Art Shift when she is called "Yui-Senpai" for the first time by Azusa.
* AscendedExtra: Jun. Started as a miscellaneous friend of Azusa's but in later chapters (and during the second season of the anime) is given her own place among the cast. In the fourth volume she even has a spot on the character introduction page with the other eight characters. [[spoiler:And as of the 2011 restart, she joins Azusa and Ui in the Light Music Club.]]
* AttentionDeficitOohShiny: Certain people from the {{Fandom}} believe Yui has this.
* BakersDozen: Episode 14 was included in the first season's final Blu-ray volume. It followed the girls New Year's Eve, but with a new twist not in the manga; they performed at a local live show. After all that was done, the episode shifted back to following the manga at the end.
* BattleOfTheBands: Yoshii sets up a competition between Houkago Tea Time and [=OnNaGumi=] in the manga's university storyline.
* BeachEpisode: Two of them. Held at Mugi's [[BigFancyHouse vacation houses]], which also includes a [[{{Hot Springs Episode}} Hot Spring]].
* Music/TheBeatles: What many see the original 4 Hokago Tea Time members as female versions of. See GenderFlipped below for more details.
* BetweenMyLegs: Turns up in episode 1; of Yui when she first arrives at the school.
* BigEater: The enormous amounts of sweets, cake and other desserts the girls eat every day during band practice don't seem to affect their waistlines at all. Especially Yui appears to have an extremely high metabolism.
** As of volume 5 chapter 14 reveals Mio gains weight of 2 kilos after entering university. When Mio tries to eat a smaller portion of her meal she then is peeved when Ritsu eats the food on her plate. Catch is what Mio eats goes to her boobs which is why she is wearing loose clothing to hide them.
* BigFancyHouse: Unknown, since you need an appointment to stay over Mugi's house. Her summer villas on the other hand are humongous. In any case, Sawako was really impressed when she drove Mugi home.
* BigNo: After the PantyShot below, Mio has a BigNo that can be heard outside the auditorium.
* BigOlEyebrows : Tsumugi (seems like a family trait, given that one of the music store's clerks realized she was the owner's daughter simply by ''looking at her eyebrows'').
** Lampshaded in the last episode of the first season: in Yui's fever-dream, Mugi's eyebrows are actually slices of pickled radish.
** In season 2 episode 5, Azusa imagines a more responsible Yui with BigOlEyebrows encouraging her in the clubroom. Moments later Jun imagines the Light Music Club playing "Kick the Can," with the can having a smiley face with pronounced eyebrows.
** The eyebrows on Azunyan's sempai (the rest of the girls) in s2-ep05, were actually strips of nori seaweed.
** One of the girls from the Occult Club has them too.
* {{Bishonen}} : There are actually [[http://img844.imageshack.us/img844/1558/guy4.png some]] [[http://img208.imageshack.us/img208/5178/teachery.png fairly]] [[http://img252.imageshack.us/img252/628/guy1y.png good]] [[http://img802.imageshack.us/img802/7607/guy3.png looking]] [[http://img443.imageshack.us/img443/3541/guy2.png male background characters]] considering the cute art style
* BitingTheHandkerchief : Yui is guilty of this at least once.
* BittersweetEnding : Natch. A few second season episodes have this, but the kicker is definitely Episode 24, and the second Extra Episode, which ends with Azusa practicing a rough version of "Fuwa Fuwa Time" with the future members of next year's light music club (which, given the voices, are [[spoiler:Ui and Jun]]) for the recruitment concert. The seniors decide not to disturb them and run away, out into the yard in the sunset, where they give their old school one last goodbye.
* BlandNameProduct : While Mio uses a "Pony" cassette player and the girls eat at "Max Burger" (complete with golden "M"), the musical instruments and equipment are shown as they are: Fender, Gibson, KORG, Yamaha, Marshall, Peavey, and VOX.
** The name "Max" has more to do with the Japanese burger chain [[http://www.mos.co.jp/ Mos Burger]], while the shop design is derived from another Japanese chain [[http://www.freshnessburger.co.jp/ Freshness Burger]].
** Played straight whenever the musical instruments are reproduced for merchandise such as figurines and the PSP game: the makers' logos are always removed.
** However, at the instrument shop, there's a "[[PunnyName Peart]]" Drums adboard, as well as several bins of "Dunlup" guitar picks.
** Mio and Azusa's tuners - Mio's is a Korg AW-2 (backlit), whereas Azusa's is a Korg AW-1, but mislabeled a Yamaha. Ironically, Korg has a license with Yamaha for actually selling a Yamaha AW-1 in Japan only, but the real one has the triple-tuning-fork logo on the clip, not written in block on the face.
* BlankWhiteEyes : Everyone. Free triangle-shaped mouths included.
* BlueWithShock : Happens occasionally, with most of the cast getting it at least once. Played comically in episode 18 season 2, when Azusa tries to [[ComplimentBackfire encourage]] Mio about her role in the Romeo And Juliet play.
** And Ritsu in episode 22 season 2, when she misplaces her exam pass.
* [[BloodBrothers Blood Sisters]] : The girls of Afterschool Tea Time eventually form a friendship that's closer than most sisters ''ever'' will be in RealLife, and nowhere is this more evident than the [[CrowningMomentOfHeartwarming tearful embrace they share in Season 2 Episode 20 ]] and [[spoiler: Episode 22, when they realize that their determination and dedication helped them all pass the entrance exams for the ''same'' university, '''''meaning that they won't have to break up the band'''''.]]
* BlushSticker : Pretty much everyone at some point or another.
* BokeAndTsukkomiRoutine : Ritsu and Mio. Complete with an image of Mio hitting Ritsu with [[PaperFanOfDoom a fan]] when Mugi talks about their relationship to each other in the manga.
** {{Lampshaded}} by Ritsu while they're in college.
** Yui and Azusa make an actual manzai performance on a talent show, in front of an audience. ([[CaptainObvious Yui is the Boke.]])
* BookEnds : Season 1 episode 10, which begins and ends with Azusa meeting up with Ui to hang out.
** Overlapping with MeaningfulEcho and IronicEcho, Yui and Azusa telling the band "It wasn't very good, was it?" bookend the entire series.\\
\\
To elaborate, when Yui is first drafted by Ritsu and Mio in season 1, they play a song for her and she says it's not very good. She joins the club anyway. At the graduation GrandFinale, [[spoiler:Azusa tells the four of them this after they play ''Tenshi ni Furetayo!'' for her.]]
** The first season also had BookEnds before the two extra episodes were shown. The first episode of the season started with Yui running to school because she thought she was late. Episode 12, the 'final' episode of the season, ends with Yui running to school because she's actually late for the festival concert.
** Azusa's first act as president of the club is grabbing onto Jun and Ui while shouting "Members secured!", exactly how she was inducted.
* BreakingTheFourthWall : A special issue of the Manga was released when K-ON was first announced to become an Anime. Among expected things (like Mio freaking out about being on TV), Yui actually straight out admitted she hadn't actually continued to sing when off panel, since no-one would notice as it's a comic.
** This happens a few times in episode 5. The characters talk out loud about how the teacher has "triggered flashback mode!" and how Sawako's art style changes.
** In episode 9, Ritsu is hit by Mio; [[RelaxOVision the hit is covered by a crayon-drawn title card]] showing Ritsu at her drums. In the next shot, Ritsu is shown with a lump on her head ''and she is [[LampshadeHanging holding the title card]].''
** When Sawako in the manga complains about not being able to tell Mio and Azusa apart without her glasses, Mio makes a minor comment on how the artist could be blamed for that.
** In Season 2 Episode 9 Yui does this in an AndKnowingIsHalfTheBattle moment when she looks directly into the "camera" and talks about how she has decided to better herself.
* BreatheOnTheFan : Ritsu does this in season 2 episode 11.
* BrickJoke
** "Your bangs are really long..."
** At the end of the ChristmasEpisode from season 1, Mio and Mugi are distressed over how much weight they gained over the holiday. Then in season 2 episode 11, once Azusa mentions that sweating a lot is sure to result in weight loss...
** "The strawberry on top is the cake's heart! Its soul!"
** Ritsu putting her hand on Yui's shoulder in the class photo in s2 ep 3, for a payoff in ep 26, virtually an entire season later!
** In season 2 episode 4, Sawako buys a green match-making good-luck charm in Kyoto. Seven episodes later, Mugi notices a green charm hanging in Sawako's car...
* BurgerFool : At one time Mugi - yes, ''[[{{Ojou}} Mugi]]'' - gets a part-time job at the local fast food restaurant.
* ButtMonkey : That one unnamed music shop clerk. Seriously, that guy does NOT get a break.
* CallBack : Yui's rush to school at the beginning of the show is mirrored in the twelth episode. She gives a touching reassurance to her past self and it's all set to Mio's rendition of [[CrowningMusicOfAwesome Brush and Ballpoint Pen]]
** The photos shown for Mio's fan club include Mio and Ritsu's first day of high school (episode 1), the first beach trip (episode 4), everyone except Yui dressed in yukatas (episode 12), and the first sunrise of the new year (episode 14).
** Nodoka reminding Yui about her career assessment paper (and Yui responding for not being smart and doesn't know what she'll do in college) in Season 2 Episode 8, traces back on the first season at Episode 1. (with [[http://static.tvtropes.org/pmwiki/pub/images/K-ON_-_08_-_Comparison_Shot_5071.jpg comparison shot]])
-->'''Nodoka''': "You really are going to become a {{NEET}} like this"
-->'''Yui''': "I feel the weight of your words [[ContinuityNod this time]]!"
** The image of the girls jumping through the air with nothing but the sky in the background in the second season 2 ED looks quite similar to the jump done in the pre-Azusa version of the season 1 OP.
** "Lycopene."\\
"Skull."
** After listening to the rest of the band play a song for her at graduation day, Azusa repeats Yui's "You're not very good at all" from the very first episode. Shortly before that, she was given the photo Ritsu took of the girls in the same episode (with a picture of Azusa added to it).
** The opening scene of the movie mirrors the opening scene of Season 1 Episode 1. There's a second callback to the first episode during the band's faux-conflict that follows, when Yui claims that she can play the harmonica. And then immediately admits that she can't when challenged by Ritsu.
* CameraFiend: The basic plot of the Uraon! short "''Ricchan's Sudden Shots Series''."
* CanonForeigner : Ton-chan and Satoshi are original to the anime.
** [[spoiler:Budokan]] was never mentioned once in the manga, which is sort of why [[spoiler:the girls are accused of forgetting their goals by fans]].
** Satoshi was mentioned in the manga, but was never shown.
* CaptainObvious
-->'''Yui''': What's that?
-->'''Azusa''': It's a tuner. It's used for tuning.
** Another one in season 2 episode 10 (which might work better in the original Japanese):
-->'''Yui''': "Will I ''grow up'' when I grow up?"
** Can't forget the ever-redundant [[http://www.youtube.com/watch?v=nz32WHGPXMI "Fun things are fun."]]
* CatSmile: Ritsu displays a prominent one in the opening of Season 1.
* CashCowFranchise - April, 2010. The pre-orders for the yet-to-be-released {{DVD}}s of K-On second season occupied ''ten'' of the Top 13 most bought movies in amazon.com Japan. And this is only after the ''first'' episode of season 2 has aired, folks. The momentum of success and die-hard fandom set by Season 1 in 2009 does not look like it will slow down ''any'' time soon, with '''twenty six''' episodes in this season altogether.
** There's [[TheMovie a movie]] coming out soon. Guess what the general reaction from the fans was...
** It's getting worse and worse. K-On model plane, K-On video game...
** There're also character cookies (quite horrifying when you realize you're basically [[ImAHumanitarian eating the girls]] in cookie form), as well as [[ICallHerVera Giitah]] cookies (yes, you CAN eat Yui's guitar), and other assorted snack foods. [[http://static.tvtropes.org/pmwiki/pub/images/k_on_merc_3843.jpg Now with pictures.]]
* CerebusSyndrome : A mild version. The second season is still a cute SliceOfLife comedy, but there's an undercurrent of sadness to it. There are frequent mentions of the fact that four of the five club members are graduating at the end of the year, and of the open question of what will happen to the band afterward.
** Made obvious in Season 2 Episode 20.
*** And then we have episode 21, where we learn that the exact length of Yui's bangs is SeriousBusiness.
** This theme is rather typical for series with a high school setting. It also happens in ''Anime/LuckyStar'', ''Manga/AzumangaDaioh'' and ''ManabiStraight'', for instance.
** Although in this case, there is really no need for the tearjerkers, since [[spoiler: the senior girls all end up going to the same college, and the Light Music Club continues with Azusa, Ui and Jun.]]
* ChaseScene : When Yamanaka-sensei runs towards the music room in episode 5. No actual SheetOfGlass or {{fruit cart}}s used, but they may as well have been.
* ChekhovsGun : When Yui nearly trips over before the concert in Episode 6. [[spoiler:Mio ends up tripping over a cord after the concert.]]
* ChekhovsGunman : During the marathon in episode 15 season two, two girls are seen passing by [[spoiler:Ritsu, Mugi, and Mio as they search for Yui]], talking about [[spoiler:UFO sightings in the area, and making it a research project for the school festival, leading the trio to hypothesize that Yui was abducted by aliens]]. Cue episode 19, where those two girls [[spoiler:turn out to be in the Occult Club, and lend their Rosetta Stone for use as Juliet's gravestone]]. And then during [[spoiler:the all-nighter after the play, the Light Music Club decides to bring some of Ui's food to thank them, and enter their clubroom... to see the Occult Club arranging a diorama of a cow being picked up by a UFO]].
* CherryBlossoms : Ever present in the first episode of Season 2. Yui collects them and even has a petal on her head while the students sing the school song.
* ChildishPillowFight : Apparently, Mugi loves them. Most likely this is part of her fascination with the details of normal middle-class life, due to being an {{Ojou}}. Similar to her fascination with fast food, part-time jobs, and hardware stores.
* ChristmasEpisode
* CicadianRhythm
* ClassTrip : The girls of the band, minus Azusa, travel for one to Kyoto.
** Which is a tad odd, since most locations depicted in the show are actually ''[[TelevisionGeography situated in Kyoto]]'' already.
* ClubPresident : Subverted by Ritsu being no more or less important than any of the other girls. She is not particularly driven and often needs "positive reinforcement" from Mio, whom she is more interested in [[{{Moe}} dressing up in a]] [[{{Meido}} maid outfit]].
** The beginning of both the anime and manga versions have this post as one of Ritsu's goals for restarting the club. Since it's nearing dissolution she doesn't need to run for the post and can obtain it by default.
** Azusa imagines herself as the Light Music Club's president, as she will be the only one left after the upperclassmen graduate. It's understood that she will become the new president next year.
* CoconutSuperpowers : KyotoAnimation very obviously tries to avoid showing the girls playing their instruments as much as possible.
** A case of MisBlamed. The manga is about as bad on this regard. In fact, the anime has probably ''more'' music!
*** Considering the [[{{Yonkoma}} manga's format]] and the fact that [[CaptainObvious most mangas are silent]], this isn't too surprising.
* ColorCodedCharacters : All the girls have one (Yui's Red, Mio's Blue, Ritsu's Yellow, Mugi's Pink, Azusa's Teal, Ui's Orange, Nodoka's Light Green, and Jun's Light Blue).
** Also, each age group has its own color on their UsefulNotes/InsideShoes, ribbon ties and track suits; the main girls are blue, Azusa and Ui's year are red, and the first years in the second season are green.
* ColorFailure : Happens fairly frequently, especially Mio.
** And then there's the instance in episode 2 season 2, where ''all'' of the girls get it. To be fair, it was in the face of an angry Sawa-chan.
** Yui suffers one in front of Sawa-chan in episode 3 of Season 1 right after finishing her make-up test.
* CompanionCube : Bordering on CargoShip at times with Yui and her guitar. She bought it because it was "cute", gives it a name (''Les Paul Gitah!''), sleeps with it, and apparently dresses it up(!).
** Of course, she dresses the Les Paul like a girl. So this CargoShip is LesYay.
*** [[{{Pun}} Les Yay Gitah?]]
**** Though Gitah is referred to as he and as Yui's boyfriend. So it's cargo, straight and lesbian at the same time.
** Which is not that much weirder that the attitude of most guitarists toward their Gibson Les Paul (most of the ones I've seen have prices ''starting'' at $2,500 USD). You simply ''want'' to pamper it.
** Her ImageSong, [[http://www.animelyrics.com/anime/keion/giita.htm "Gitah ni Kubittake"]] is pretty much a love letter to Gitah.
* ConspicuousCGI : Besides the season 2 openings, most of the cars in season 2 are very clearly CGI.
* ContinuityNod : Turtle plushie that Ui won in episode 5 makes its appearance in episode 17. Can be seen with Mio when she visits Ui with other HTT members.
** In Episode 22, the scarf Ui's wearing is the same one Yui gave her during Christmas.
** The two women served by Mio at the MaidCafe (S2 E18 17:17) go to the live show at the festival two episodes later and are given HTT T-shirts to wear (S2 E20 10:45).
** The backstage passes the band received during Season 1's bonus episode (Episode 14) are still seen stuck to their instrument cases throughout Season 2.
* ConvenientlySeated : Yui and Nadoka both sit next to the window in the last two rows in class.
* CooldownHug : Yui performs one on Azusa. It works like a charm.
* CornerOfWoe : More like a corner of fear and denial, which Mio goes into regularly. In episode 5, Yamanaka-sensei heads into one, only to discover that Mio is already there.
** Ritsu has hers too in episode 3 of season 2, when wishing to change instruments from drums.
* {{Cosplay}} : Sawako has a thing for dressing up the other girls. Possibly also counts as CosplayOtakuGirl, but Sawa hasn't shown any otaku tendencies so this area is a little gray.
* CranialEruption : Poor Ritsu.
** Most of the time it's her own fault anyway.
** Sawako-sensei gets one after attempting a {{Skinship Grope}}.
** The correct term for this in Japanese, is a 'tankobu' (たんこぶ - literally 'bump' or 'swelling' on the head). It's a standard comic device for when the 'tsukkomi' (straight man, or Moe) hits the 'boke' (fool, or Larry/Curly/Shemp) for doing/saying something idiotic. If you look in S1-EP03, Ritsu even earns a stacked set of tankobu, which hilariously resemble stacked New Year mochi rice cakes.
* CrossPoppingVeins (Mostly Mio, but it's seen in many of the main cast.)
* CulturalCrossReference : Most of the famous musicians the band members talk about are Western rock stars. Ritsu names her biggest inspiration as a drummer as [[Music/TheWho Keith Moon]], of all people, although she's quick to point out that she doesn't want to imitate his offstage behavior.
* CulturalTranslation : The dub says how much Yui's guitar is worth in dollars instead of yen. "Moe-moe kyun~" is also swapped out for "The power of cute compels you~".
* CutenessProximity : Azusa provokes this reaction regularly from the older club-members, but mostly Yui.
* DarkIsNotEvil : The girls from the Occult Club, despite looking like they're in some sort of cult, are actually nice people and even help the girls with their Romeo and Juliet play.
* DatePeepers : In episode 11 of the first season, Ritsu, Mugi, and Azusa spy on Mio, Yui, and Nodoka in a cake shop. Ritsu gets a little [[ClingyJealousGirl jealous]] that Mio seems to be very friendly with them, and decides to crash into the latter group.
* DaydreamSurprise : Azusa has four of these in episode 13 of season 2. Lampshaded when she asks Mugi to [[PinchMe pinch her]] and near the end of the episode wondering if it was AllJustADream.
* {{Defictionalization}} : A cassette with the tracklist the band put together in season 2 episode 23 was released three weeks after the series ended its broadcast run.
* DelayedReaction : Usually involving Ritsu or Yui. ([[{{Cloudcuckoolander}} Especially Yui]].)
-->'''Mugi''': Mio asked me to go request some stage time for the school festival. But they denied me since the Light Music Club isn't recognized as an official club.
-->'''Yui''': Oh, I see.
-->''(six seconds pass)''
-->'''Yui''': Huh?
** Ui has one when she realizes [[LivingEmotionalCrutch Yui]] will be away a school field trip overnight. She nearly breaks down in tears until Azusa offers to sleep over.
** Also when [[spoiler:Yui cuts her bangs a bit too much...]]
** Needless to say, it's used pretty often throughout the series.
* DescriptionCut : Used during Azusa's introduction in the manga:
-->'''Azusa''': I heard the recording of the live performance at last year's school festival. The guitarist was so awesome! I really admire her!! The level of this school's Light Music Club must be really high, right?
-->''[Next panel]''
-->'''Yui''': How do I play a C chord again?
* DescriptionPorn : Episode 2x02 did nearly a full minute's background and detail on Sawako's surprisingly valuable Gibson guitar, explaining why the girls were basically getting 500,000 yen for free.
** Just take a look at the ShownTheirWork trope a few scrolls down...
* DetachedSleeves : Part of Sawako's and Yui's heavy metal costumes.
* DoIReallySoundLikeThat : After hearing a recording of herself, Azusa apologizes for sounding so strict. Mio's also embarrassed of her voice, to a lesser degree.
* DoesNotKnowHerOwnStrength : Most of the time, Mugi effortlessly carries her Korg Triton by herself, one of which weighs as much as a [[http://h3.abload.de/img/mugikeyboardsc5t.jpg modern guided anti-tank missile with its launch tube and computer]].
** Possibly lampshaded during her outing with Ritsu. The latter brings the former to an arcade and tries out an arm wrestling game. Ritsu lost despite using both arms and putting her entire weight on it while Mugi effortlessly beats it literally singlehandedly.
** In the first festival episode (S1 Ep.06) Mugi is shown carrying numerous heavy things past Yui, who is struggling to carry only one (an amp).
** Brought up again as a kind of ContinuityNod in the restarted manga. Akira, a university freshman and member of the university's own light music club ends up making Mugi cry due to something she said. In an effort to make it up to her, she lets Mugi slap her, thinking that a pampered Ojou like Mugi would probably be pretty weak. Boy was she wrong; the slap quite literally [[PunchedAcrossTheRoom sends Akira flying]] [[http://www.mangareader.net/k-on/59/5 across the room.]]
* {{Doppelganger}} : In "Listen!!"'s credit sequence, there's a second, fairy/Ant Queen-like Mio inside [[LevelAte the giant cake]], with no indication of who and/or what she's supposed to be, complete with antennae and butterfly wings.
** There's another [[http://i43.tinypic.com/ot15w7.jpg Mio clone]] in the school; her name is Fuuko Takahashi, and she wears [[{{Meganekko}} glasses]] and her jacket open
** Another side character example: [[http://images2.wikia.nocookie.net/__cb20111217173256/k-on/images/7/7a/FumieKimura1.jpg Fumie Kimura]] and her namayake friend [[http://images2.wikia.nocookie.net/__cb20111215171944/k-on/images/4/4e/Fumie_1st_year.jpg here]] seem to look alike. Another background girl, shown in this [[http://i570.photobucket.com/albums/ss148/kewlgal111/8a55c099.jpg picture]] shown in the same scene resembles both girls as well.
* DraggedByTheCollar : Mio to Ritsu in episode 1 season 1, for being too aggressive in trying to recruit people
** Tiny-little ''Azunyan'' dragging ''Yui'' crying off to study in season 2 episode 9.
** Mio ''flies along behind Sawako like so much fluttery clothing'' when Sawako drags her out of the music room at mach speed to get [[{{Cosplay}} changed.]]
-->Ui: What was that?
** And Ritsu to Mio in episode 18 season 2, when the latter refuses to practice for their school play, ''Romeo and Juliet''.
* DreadfulMusician : The band, [[GeniusDitz at first]], is quite lacking in the musical talent department.
[[/folder]]

[[folder:E to H]]
* EarlyBirdCameo : Yui passes Mugi, Ritsu, and Mio on the way to school in the first episode.
** The StudentCouncilPresident makes an unvoiced cameo appearance in episode 6, which takes place halfway through the first year. In the manga storyline, she's not introduced until the very end of the second year.
* EarnYourHappyEnding : Quite literally in the case of the four original members of HTT; their love and friendship was so strong that it gave ''all'' four of them the resolve to study hard and ''pass'' the exam to Mugi's prestigious Private University as one, [[{{Tearjerker}} so Afterschool Teatime will]] ''[[CrowningMomentOfHeartwarming never break up.]]''
* ElegantGothicLolita : The outfits of the girls in the first season ED are highly influenced by this.
** Even more so the outfits they wear while singing "Fuwa Fuwa Time".
** Also, the [[http://static.tvtropes.org/pmwiki/pub/images/goth_loli_duo_5340.jpg Goth duo]] at the live house.
* EmotionlessGirl : The girls of the Occult club have this as their shtick.
* EvenTheGirlsWantHer : Mio has her own fanclub, complete with official membership cards.
* HairDecorations : Pretty much a necessity since it's hart to tell Yui, Ui, and Ritsu apart from each other (aside from their bust size) without the accessories.
* EveryoneMeetsEveryone : When the first episode begins, only Mio/Ritsu and Yui/Ui/Nodoka know each other.
* EvolvingCredits : Azusa is added to the opening after she joins the club. If you listen closely, you can also hear an extra guitar part added to the song.
** This is more noticable with you listen to the first release of the "Cagayake Girls" OP song and the "Cagayake Girls (5-nin version)" released a bit later.
* ExcitedShowTitle : And the second season is even more excited: K-On!!
* {{Expy}} : Some fans have argued that Kakifly hasn't been very imaginative when creating new characters for the restarted manga: Sumire is Mugi+Mio, and Nao is Nodoka+Yui. The new University characters are existing characters with their most distinctive attribute removed: Akira is Azusa without being a KidSidekick, Sachi is Ritsu without being a {{Tomboy}}, Ayame is Mio without being a ShrinkingViolet, and Kana and Chiyo are Sawako and Norimi as grad students.
* EyeCatch : The cassette and reversing cassette animation in each episode.
* EyelidPullTaunt : In the second season opening titles, Ritsu does a half-hearted version, with the finger being more on her cheek than close to the eyelid. It's adapted directly from a [[http://static.tvtropes.org/pmwiki/pub/images/k-on_red_eye_6507.jpg title page in the manga]].
* FaceFault : The whole audience does this in Episode 6's music-video-sort-of-thing.
** Ritsu does an absolute ''beauty'' in Season 2, Episode 4. While running.
* FakeBand : Only Houkago Tea Time ("Afterschool Tea Time", a.k.a. HTT) and Death Devil have released songs on CD. The voice actresses do their own singing, but music is performed by studio musicians except in the Radion CD (see above under CrowningMusicOfAwesome). Other fake bands which have been mentioned in the show include Love Crysis, Kamakiri, Death Bang Bang Ji (punk), Black Frill (goth loli) and Namaha Ge.
* {{Fangirl}} : Mio has a fair share, but most notable are Jun and Megumi, the latter being the student council president and the ''president of her fan club''.
* FashionableAsymmetry : In the second season ED, both Mio and Ritsu wear one glove each, Mio on the left hand and Ritsu on the right.
* FauxHorrific : In episode 2 of Season 2, after cleaning out the closet of the music room, Mio and Azusa find out that Yui left a lot of things still and get mad at her. Yui pouts and claims that Ui would get mad and make a scary face if the latter brought more stuff home. Cue cutscene showing a "scary" Ui giving a thumbs up to Yui, after the latter had dropped other stuff she took home earlier and apologized profusely. Both Mio and Azusa wonder if Ui isn't the older, more responsible sister after all.
* FilmingForEasyDub : Mio has a tendency of hiding her mouth behind her microphone during the end credits.
* FirstNameBasis : Pretty much applies to almost everyone, even Sawa-chan-sensei.[[spoiler:..except for Okuda-san.]]
* [[FiveManBand FiveWomanBand]] : One of the few ''literal'' examples. Being [[TheHero Yui]], [[TheLancer Mio]], [[TheSmartGuy Mugi]], [[TheBigGuy Ritsu]], and [[TheChick Azusa.]] Sawako takes on some of the elements of TheObiWan.
* {{Flanderization}} : In the non-canon Anthology guest strips, Ui's infatuation with her sister and Mugi's love of GirlsLove are often all there is to their respective characterization.
* {{Flashback}} : Occasionally with FlashBackBackBack.
* FlippingTheBird : ''Yui'' almost does this in the MusicVideo that plays during their first festival performance... and then turns it into a peace sign.
* FourGirlEnsemble : Later on, it becomes a [[Main/FiveManBand Five Woman]] [[IncrediblyLamePun Band]] (sorta) once Azusa Nakano joins the club.
* FourTemperamentEnsemble : Yui and Ritsu are sanguine, Mio is either melancholic or choleric, Azusa is somewhat choleric, and Mugi is phlegmatic.
* {{Foreshadowing}} : Sawako's driving through the marathon's course, and Ui notices "We're almost home" (S2 E15, 07:05). Later in the episode, when Yui's lost, Ui guesses where she is because they're close to her home.
* FreezeFrameBonus : Episode 2x13, take a closer look at Azusa's yakisoba when she goes down the slide.
* FreudianSlip : Mio, about Nodoka. Either Mio thinks that Nodoka acts too much like Yui's mom or she has mommy issues.
* FunTShirt: When Yui is hanging out at home, she almost always wear t-shirts with various words written in katakana on them, ("Honeymoon", "Champion", "Celebrity"...). [[http://ishop.tbs.co.jp/special/tbs/k-on/fashion.html#hent Plenty are avaliable through the official TBS store]].
* GenderFlip : Certain fans have come to regard the original four girls of Hokago Teatime as female versions of ''Music/TheBeatles'', with analogous personalities and roles (IE. Yui = JohnLennon, Ritsu = RingoStarr, Mio = PaulMcCartney, Tsumugi = GeorgeHarrison). Their crossing of Abbey Road in The Movie only further strengthens the analogy.
* GenerationXerox: Hokagou Tea Time mimics the closely-knit nature of its predecessor, Death Devil, which Sawako was a member of.
* GilliganCut : Episode 4 of the 2nd season has plenty of these, courtesy of poor Sawako-sensei.
-->'''Ritsu:''' Take a picture with us, Sawa-chan!\\
'''Sawako:''' No I won't...!\\
''''\\
'''Sawako:''' v(^_^)
** Also:
--> '''Mio:''' So, did you figure out how to get there?\\
'''Ritsu:''' You bet I did! It's this way! Follow me!\\
''''\\
'''Ritsu:''' We're lost...
** Later in that same episode, Yui asks Sawa-chan to talk with them for a few minutes. Mugi offers to sweeten the deal with some snacks, but Sawa-chan politely refuses... then in the very next scene she's eating with them and complaining that the girls are ruining her reputation as a teacher and why the other girls are referring to her as [[SenseiChan Sawa-chan]] as well.
** A smaller example (S2 16 16:13):
--> '''Azusa:''' We really need to practice today, really need...\\
''''
* GirlishPigtails : Azusa. Also Jun from her class.
* TheGlomp : Azusa is a regular recipient of this from Yui. And [[http://static.tvtropes.org/pmwiki/pub/images/azusa_glomp_5539.jpg this]] is what happened seconds after she said that she wanted to join the club.
** Azusa herself picks up the habit in the 2011 restart.
** Everybody gets into the glomping in the second season's [=OP2=].
** Yui glomps the new character, Akira, after meeting her in the college K-on club.
* AGoodNameForARockBand : The band-naming session goes nowhere fast, but it does include Yui suggesting "[[EgocentricTeamNaming Yui Hirasawa and Her Happy Friends]]" (Ritsu immediately comments on this: "Hey, are we supposed to be part of the background?"). Sawa-sensei is annoyed that the debate is delaying her tea-time and forces the band to adopt the name "Afterschool Tea Time".
-->'''Sawako:''' You don't need to put that much thought into a name.
** When Afterschool Tea Time meet Love Crysis (the band whose drummer went to junior high with Ritsu), Yui is envious of how much cooler their name is.
** Sawako's metal band, Death Devil, has a good name and an even better logo.
** Black Frill is an ''excellent'' name for a Gothic Lolita duo.
** One of Mio's rejected suggestions for a band name, Pure Pure, ended up getting recycled into a song, "Pure Pure Heart".
** On the other hand, one of Ritsu's rejected suggestions for a band name was [=OnNaGumi=] (Gang of Girls), and by a truly ContrivedCoincidence, this turns out to be the name of Akira's band when they meet her in college. The other band in the college Light Music Club is called Guitar Allergy.
** Sawako seems to have established Wakaba Girls as the name of the band formed by Azusa, Ui, Jun, Sumire and Nao.
* {{Gonk}} : A mild example of this trope, but the beady-eyed first-years in the Jazz Club and Mio's fan club are intentionally plain and generic-looking.
** The girls' classmates are depicted as [[GenericCuteness rather pretty]], though. Is this a school for fashion models?
* GossipEvolution : Mainly played for laughs in season 2 episode 24, where [[spoiler:during the graduation ceremony, while Yui is holding onto the thank you card for Sawa-chan]], the message, started by Mio, changes from [[spoiler:"Miss Sawako is worried about you, Yui"]] to [[spoiler:"Miss Sawako failed"]] by the time it reaches the end. Afterwards, it turns out that it was [[spoiler:Ritsu]] who screwed up.
* GratuitousEnglish
** In episode 10, we have this exchange between Yui and Ritsu in an ImagineSpot by Azusa: [[MakesSenseInContext "I'm flyiiiing!" "Yes! Yes! Yes!"]]
** Mugi in episode 14 season 2: [[http://www.youtube.com/watch?v=qggN2PlqOYA&feature=related "Just a moment, please".]] {{Lampshaded}} by Ritsu, who wonders why she said it in English.
** Ritsu herself in episode 22 season 2: [[http://www.youtube.com/watch?v=oJmXjTES_lQ "That's answer three!"]]
** Ritsu again in episode 10, season 2: [[http://www.youtube.com/watch?v=ZdXJsqD1-wA "I am a pen."]]
** Jun's ImageSong begins with the lines "I wanna be a cool bassist girl. Yes, I wish, I wish, love! Oh rainy day!"
** After-School Tea Time's songs are full of Engrish; Mio seems to be responsible, as they're usually her songs. Sometimes the same line will occur in both languages as if for emphasis. ("We'll sing utauyo!")
** Season two's special episode has Yui's [[http://www.youtube.com/watch?v=CfmKdMbIT2Q&feature=related "NO RICE - NO LIFE"]] line.
** Yui's important question to ask [[http://www.youtube.com/watch?v=BSFBJOHUJaI&feature=colike while visiting an English speaking country]].
** The Death Devil members' stage names, presumably to sound cooler: Catherine, Christina, Jane and Della. Kawakami : the manager of the live house : wasn't in Death Devil, but is referred to by Sawako as "Janice".
** "Don't say lazy" has two. "Please don't say you are lazy, datte honto wa crazy"
** While TheMovie has a lot of justified English : since they're in London : it does include Yui shouting "Sky High!", with her explanation being that she thought it would sound cool.
* GratuitousFrench : Ui's first two {{Image Song}}s contain some of these in either the lyrics or the title (Oui! Aikotoba)
* GreenEyedMonster : Jun becomes quite jealous of Azusa when she starts to hear about all the fun the latter is having with the light music club, such as going to the beach to practice music (or rather goofing off), hanging out together at a music festival, and the close bonds they all have with each other.
* HappilyMarried : Yui's parents.
* HardWorkHardlyWorks : The anime shows HTT delivering very good performances even though they constantly slack off when they're supposed to be practicing.
* HiddenBuxom : Mio hiding her growing breasts with baggy clothes.
* HoldingHands : Possibly IntertwinedFingers: Yui and Ui during the ChristmasEpisode.
* HollywoodToneDeaf : In one flashback to Yui's childhood, her {{seiyuu}} sings an [[StylisticSuck appropriately ear-grinding]] song about turtles (she was only a little child). Some people thought it was cute.
* HonestAxe : Yui and Ritsu play this out in front of Nodoka, when they're trying to get an air conditioner.
-->'''Ritsu:''' Is it the gold AC you'd like? Or is it the silver AC?\\
'''Yui:''' My Lord, I just want a regular AC.\\
'''Ritsu:''' How honest you are! Then I shall bestow upon you a brand new AC.\\
'''Yui:''' Thank you, My Lord!\\
'''Nodoka:''' What was that supposed to be?
** The Honest Axe Story is retold in its entirety in the 4th DVD special in Season 2. We also learn that the story convinced little Yui to become a woodcutter when she grows up. [[spoiler:She would drop [[IWasToldThereWouldBeCake cakes]] instead of axes]]...
* HotMom : Yui and Ui's mother turns out to be quite the beauty.
* HotTeacher : Sawako. Her glasses also add a HotLibrarian element to her look.
* HugeSchoolgirl: Sachi.
[[/folder]]

[[folder:I to L]]
* ICallItVera : Yui nicknames her guitar "Gitah".
** In the second season, Yui has taken to calling Mio's bass "Elizabeth/''Erizabesu''" (which Mio inadvertently does as well, to the amusement of Mugi, Ritsu, and Yui) while Azusa subconsciously considered naming her Fender Mustang "Muttan."
*** Elizabeth's name comes from the fact that it's a bass guitar (bass sounds like "beth"). This is emphasized the clearest in the dub, where they just have Mio call it "Elizabass". Muttan is from the sound of "Mustang" without the "g" sound (the "s" sound is rather faint when she pronounced it). Gitah's origin should be rather obvious.
** In the new manga, Akira calls her black Les Paul "Rosalie".
* IdenticalPanelGag: [[http://mangafox.me/manga/k_on_anthology_comic/v01/c005/3.html Happens occasionally]]; this is a {{Yonkoma}} after all.
* IJustLikeSayingTheWord : Mugi: "Cut!"
* [[InformedAbility Informed Disability]]: We are repeatedly told that Houkago Tea Time is "not very good" even as late as S2 Ep24. You'd never know it from listening to them though. Or from the number of fans they seem to have picked up from amongst their schoolmates for that matter.
** In S2 E24, she was talking about a specific song, which the girls may not have had enough time to rehearse.
* IWasToldThereWouldBeCake : Frequently used as motivation. For example, when Yui falls asleep in the classroom [S2 E02], the girls try to wake her by saying "We've got cake for you." She looks up, [[TheCakeIsALie doesn't see any cake]], and goes right back to sleep.
* IdiosyncraticEpisodeNaming : Every episode title is a noun (or noun phrase) followed by an exclamation point.
* IdiosyncraticWipes : The second season has a bunch of different wipes between scenes, like [[http://static.tvtropes.org/pmwiki/pub/images/k-on_wipe_4921.jpg]], for example.
* ImageSong
* ImagineTheAudienceNaked : Well, imagine the audience is Ritsu but close enough.
* IncrediblyLamePun / PunnyName : "Only Mio fits Ro-'mio'!"
* InherentlyFunnyWords
** ''Sharekoube''[[hottip:* :skull]].
** ''Lycopene''.
* InstantBandages : Seems to have replaced Ritsu's [[CranialEruption Cranial Eruptions]] by the second season.
* InstantFanclub : Mio gets hers right after the performance at the culture festival.
* InvisibleParents: Played straight during the regular seasons, except for one brief shot of Yui and Ui's parents celebrating Christmas in a foreign country. Averted in the movie, where Yui and Ui's parents are seen at home briefly right before Yui goes to London with her club.
* {{Iyashikei}}
* JapaneseDelinquents : The girls appear to portray themselves as such in the No, Thank You ED, with the unbuttoned uniforms, loose ties, and spraypainting.
* JapaneseHonorifics : These get a real workout in the show.
** Yui refers to all her friends by ''-chan''.
** Mio is embarrassed when asked to use Yui's name [[FirstNameBasis without honorifics]].
** The music store employees all use ''-sama'' and ''-ojousama'' when they talk to [[{{Ojou}} Mugi]], while her correct and proper butler refers to her with the formal mouthful "Tsumugi-ojousama".
** Ui gets found out when she uses ''-san'' instead of ''-chan'' for Yui's friends. It also doesn't help that she calls them by their proper names instead of their nicknames.
** Azusa always uses ''-[[SempaiKohai sempai]]'' for the other girls in the club.
** While everyone uses ''-sensei'' for Yamanaka, they use different emphases for when she's being admirable, perverted, or just friggin' awesome. Yui calls her Sawa-chan-sensei, which later even gets copied by her other students, much to her dismay. Or not.
** Azu''-nyan'' is less of an honorific and more of a reference to [[CatGirl Cat Girls]] or [[VerbalTic Verbal Tics]].
*** Yui introduces Azusa to her neighbour as "Azunyan", so she goes on to call her "Azunyan-san", one of the few times she gets an honorific on top of the nickname.
** When in class, Sawako refers to her students as Last Name''-san'', but is on FirstNameBasis with the girls when they're having tea in the club room.
* KansaiRegionalAccent : During a school trip to Kyoto, Ritsu suggests that they should all talk like this while they're there. Mugi actually pulls it off. It helps that MinakoKotobuki is from Hyougo, and grew up speaking this dialect.
** Gohan wa Okazu includes a bit Kansai when Yui sings about okonomiyaki.
* {{Kimodameshi}} : Mio and Azusa participates in one during the second BeachEpisode. They stop playing when Sawako turns up out of nowhere to scare Mio half to death, leaving Ritsu alone in the woods with a wet sponge, waiting for them to show up.
* {{Kotatsu}} : Yui almost has to be surgically separated from hers.
* LastNameUltimatum : Ritsu's reaction to Azusa laughing at her being cast as Juliet in the SchoolPlay: "NA-KA-NOOOO!"
* LateForSchool : Yui, in the first episode. Ends up being subverted when it turns out she was actually an hour early.
* LawyerFriendlyCameo : The Japan Exhibition in London includes a bright pink Franchise/{{Godzilla}}, with the trademark roar.
* LensFlare : Mostly in beach shots.
* LicensedGame - ''K-On! Houkago Live!!'', for {{PSP}}. It's a RhythmGame, and it {{Averted}} TheProblemWithLicensedGames by being developed by the company that made ''[[{{Vocaloid}} Project Diva]]''. [[ThatOneLevel And yes, some songs are PD-level difficult.]]
* LimpAndLivid - Whenever Mio is about to go Krakatoa on Ritsu for screwing things up with her apathy/stupidity ''again.''
** Also, whenever Sawa-chan-sensei's ladylike mask cracks and turns her into "Katherine." Most notable examples include when the girls huddled together in terror as she got a jack-in-the-box-in-the-face for ''her'' Christmas present, and when she CRACKS and shows just how "Death's Devils is NOT CUTE" at her friend's wedding.
* LivingProp : Most of the class in the second season, most notably Tachibana Himeko, formerly "The Girl Who Sits Next To Yui"
** OneSteveLimit : Exception: there are two girls in Class 3-2 named Toshimi.
* LookWhatICanDoNow : Subverted. Yamanaka-sensei takes Yui away for vocal training... except that they trained too hard and Yui loses her voice.
* LoveLetterLunacy : Ritsu gets a love letter at one point, which distresses her highly:until [[spoiler:it turns out to be song-lyrics written by Mio]].
* LowerDeckEpisode : Episode five of season two, which focuses on the second year student trio (Ui, Azu-nyan and Jun) while the ClassTrip episode (the previous one) is happening concurrently.
* LuminescentBlush : Yui's in response to Mio's cuteness is especially endearing.
** Sawako-sensei manages to blush through her mask during the flashback in which she confessed to a guy.
** Numerous characters manage to blush through ''the hair on the back of their heads'' when their face is not visible because they have turned away in embarrassment.
* LyricalDissonance : In spite of Mio writing lyrics about stuffed toys, food and stationery (see SickeninglySweet), HTT plays moderately hard pop-rock songs, often with a retro-[[TheSixties '60s]] style.
[[/folder]]

[[folder:M to P]]
* MagicSkirt: Outright defying physics by being suspended in the air pointing upwards sometimes.
* {{Meido}} : Ritsu suggests dressing Mio up as one for the school festival, spawning "Moe Moe~Kyun!" [[CranialEruption She gets a bump on the head for the suggestion.]]
** All five girls work at a MaidCafe for a day to help Mio overcome her shyness.
** When her uniform is drenched, Yui chooses that one from the club's extensive cosplay costumes collection (S2 06 08:04).
* MediumAwareness:
** In one strip, Sawako comments that without her glasses, Mio and Azusa look the same. "A Criticism of the Manga Artist?" is Mio’s response.
** Likewise a Bonus Comic celebrating the anime adaptation has the characters aware that they’re in a comic. Because an anime actually has sound, Yui realizes she couldn’t skip singing like she can in the comic. And to look better for broadcast tv, Sawako puts on makeup.
* TheMerch: From shirts to ties to guitar covers to [[ImageSong Image CDs]] to [[http://static.tvtropes.org/pmwiki/pub/images/kon-music-shop_2648.jpg replica guitars]] and [[CrackIsCheaper hilariously overpriced rice]]. It safe to assume it won't be going away for a while.
* MinionMaracas: Ritsu shows Mio some pictures at the end of the first BeachEpisode (S1 04). One of which happens to be rather embarrassing to Mio. Cue this trope, with Mio demanding that Ritsu delete the photos.
* MistakenForGay: In the movie, after glimpsing Yui's attempts at writing lyrics that include a very prominent "AZUNYAN LOVE <3", Azusa begins to think there might be more to Yui's constant glomping.
* MohsScaleOfRockAndMetalHardness : The band's songs tend to not be too hard and are within levels three to five. In Sawako's {{flashback}} she recalls making the journey through virtually the entire scale. Her ImageSong with Death Devil sounds much tamer, however.
** Their hardest song is the second ED from the second season, "No, Thank You", which could deserve a level 6.
* TheMovie : Released on December 3, 2011. The plot involves Hokago Tea Time [[VacationEpisode going on a trip to London.]]
* MundaneMadeAwesome:
** Ritsu dive-rolling into the room in Episode 3. Repeated three times from three different angles. Neither characters nor audience is impressed, though the latter is generally amused. One fan [[http://www.youtube.com/watch?v=HkU9s42JMzE decided to make the scene even more over-the-top awesome.]]
** [[http://www.youtube.com/watch?v=lNgHVXdwHiE&NR=1 Hey, Sawa-sensei gets her moment too.]]
** Heck, Ritsu got another one at the 8th episode of season 2.
* MyEyesAreUpHere : Ui says something to this effect to Sawako. Though she WAS pretending to be Yui, and Sawako DID prove that she could tell the two apart by bust size.
* MySkullRunnethOver : Yui forgets all the chords she learned after cramming for an exam. To be fair, she had just learned those chords.
-->Yui: Don't talk to me. Everything I memorized will fall out.
* NewspaperThinDisguise : When Ritsu - along with Mugi and Azusa, who she dragged along - spies on Mio and Nodoka at the cafe, they hide their faces behind menus.
* NoAntagonist : The only real source of conflict in ''K-ON!'' is the possibility of the band getting broken up, whether it's because they don't fulfill the requirements to exist as a club, or in the second season, if the girls were to go to different universities. However, they always end up doing the right things to keep themselves together, and nothing bad ''ever'' happens in this show.
** The restarted university and high school manga show that the real conflict present throughout all of ''K-ON!'' is laziness vs. diligence. Laziness usually wins.
* NoNameGiven : We never find out the real names of Death Devil's drummer and bassist [[TheVoiceless (who don't get any lines)]]; the liner notes of their CD single only give their stage names, Jane and Della.
** In-universe example with [[spoiler:Okuda-san]], at least for the first few months they've been together.
** The two girls in the Occult Club. Officially, they've only been listed as "Occult Club member A" and "Occult Club member B".
* NoblewomansLaugh : Ritsu, oddly enough, when she puts on airs over her test-taking skills.
* NobodyLovesTheBassist: [[AvertedTrope Averted]]. ''Everybody'' loves Mio, both within the band and outside. Mio even is the only band member with her own fan club! The HTT songs also tend to have noteworthy bass lines, mixed way up front.
* NobodyPoops : Partially averted: In the penultimate episode of Season 2, the four senior members of the Light Music Club tells Azusa they all have to use the restroom because "they've been drinking lots of tea" while waiting for her. The rest, thankfully, takes place offscreen.
* NonIndicativeName : In Sawako's school days, the ''light music'' club played [[spoiler:really insane metal]].
** The school's annual "marathon" is really only a 5K run.
* NowThatsUsingYourTeeth : Yamanaka-sensei, when demonstrating her old skills.
* ObstructiveBureaucrat : Beautifully averted in episode 11 of the second season. The girls want to have an air conditioner for their clubroom, but they have to go through the student council to get it. Ritsu prepares herself to explain why they should be given one, expecting a lot of opposition, and is surprised when the student council's answer is "Yes, sure, you can have one."
** Heck, the only reason they have the problems they do with the student council is because they keep forgetting to file the paperwork for them.
*** ...and Nodoka ends up doing most of the paperwork for them anyway.
* OddCouple : The shy and fearful Mio and the energetic (and slightly {{Jerkass}}) Ritsu. They've been friends since at least elementary school, but one wonders how Mio put up with her all that time since Ritsu constantly plays on Mio's phobias and shyness.
** Mostly because Ritsu's not always a jerk... there are many examples in season 2 when Ritsu encourages Mio gently, as though she's known her weaknesses for a long time. Mio reigns in and makes Ritsu fess up to her blunders and provides grounding. They're pretty well-matched as friends, actually.
* OhCrap: When all the girls huddled together in adorably SuperDeformed terror as Sawa-chan cops a jack-in-the-box in the face on Christmas Eve.
* {{Ojou}}: Mugi
* OneGenderSchool
* OnlySixFaces: Strangely mixed with CastOfSnowflakes, since everyone in the class look different despite having almost the same facial features (including the two girls with the '60s-manga-styled eyes).
* OnionTears : Happens to [[http://www.youtube.com/watch?v=0pQHOUcytVs&list=FLzXABVUMyzXf2x3jtFicyWA&index=1 Yui and Ritsu]] in episode 10 of Season 1.
* OrbitalShot : The opening of the second season has several around the whole band.
* OvertookTheManga: Averted : the second season showed episode 24 (concluding the main story) after the manga had finished about a week earlier.
* PaintingTheMedium : The exposition about the girls' music teacher/club sponsor is revealed to be Ritsu talking the whole time.
** Later, Mio has an InnerMonologue, which Ritsu adds narration to. Mio tells her to stop doing that.
** In the manga chapter where Ayame and Sachi flash back to their high school days when Akira used to be much more feminine, Ritsu repeatedly points up ''to the previous panel'' to ask "Who is this person you're talking about?"
** In the PSP game, Mio's notes are dominated by directional buttons instead of shape buttons, since she's a left-hander.
* PantyShot : There's a rather gratuitous [[http://static.tvtropes.org/pmwiki/pub/images/k-on_panties_3095.jpg panty-shot of Mio]] after their performance at the school cultural festival. [[http://static.tvtropes.org/pmwiki/pub/images/k-on_ricebowl_7491.jpg Except the anime audience doesn't get to see it, as KyoAni replaced that with a bowl of rice]]. Everybody in the auditorium, on the other hand....
** Contrarily to most panty shots in anime, it's actually not gratuitous, since it's heavily commented upon (even in the second season), and was one more obstacle for Mio to overcome her shyness.
* PastimesProvePersonality: Aside from the obvious interest in music and song-writing shared by the club, the anime decided to make Mio a sports-fan for a throwaway line in addition to her reading hobby.
* ParasolOfPrettiness : Fittingly used by Mugi in the season 2 opening titles.
* ParentalAbandonment : None of the girls seem to deal with their parents a lot, even though they are only 15 years old at the start of the series.
** While Yui specifically says her parents like to travel a lot, she seems to be the only one with actual abandonment going on. Mugi mentions spending time with her parents all the time, Mio and Azusa talk to their respective off-screen or off-panel mother a few times, and so on. Like ''{{Peanuts}}'', most adults in ''KOn'' are apparently HeWhoMustNotBeSeen.
** [[spoiler: [[http://static.tvtropes.org/pmwiki/pub/images/TheHirasawas_8506.jpg The Hirasawa couple are finally home! After three years.]]]]
* PassingTheTorch
* PerformanceAnxiety : Akiyama Mio
* PictureDrama : The [=DVD=] [[{{Omake}} specials]].
* PinkySwear : Ritsu and Mio, when they decided to form a band. At least, [[SelfServingMemory according to Ritsu]]...
* PissTakeRap: Done on "Fuwa Fuwa Time". Helps that the music background sounds close to something Nu-Metal-esque:
-->But that's the biggest problem, ya see\\
'Cause then I'll need to think of a topic to speak\\
And it ain't gonna be natural for me\\
To do that in the first place, I think
* PlayingAgainstType : An in-universe example, when Mio and Ritsu are forced to play Romeo and Juliet, respectively.
** Also out-of-universe, SatomiSato had a main role before and after Ritsu whose character type she plays more often, as in subdued characters like [[HellGirl Yuzuki Mikage]] or [[LightNovel/OreNoImoutoGaKonnaNiKawaiiWakeGaNai Manami Tamura]]. Likewise with her role as Shichijou Aria in ''SeitokaiYakuindomo'', who is now a perverted {{Ojou}}.
** Speaking of ''SeitokaiYakuindomo'', just try comparing Shino to Mio.
** Mio's seiyuu voices a character in ''SeikonNoQwaser''. No, you don't need to know which character it is for it to clash with Mio, you just have to know that the character is from '''''Seikon no Qwaser'''''.
** Subverted with is Yui's seiyuu which was a CastingGag of Yui.
* PolarBearsAndPenguins : {{Justified|Trope}} since it's part of an ImagineSpot by Yui and Ritsu. It also includes a mammoth.
* PortmanteauCoupleName: An in-universe use: When Yui and Azusa perform as a duo, they decide to call themselves [=YuiAzu=].
** The title for episode 19 of season 2 is "[[RomeoAndJuliet RomiJuri!]]"
* PoseOfSupplication
* PowerPop: Much of the music that Hokago Tea Time plays would fall under this umbrella, although they kind of sound more like ThePillows [[XMeetsY plus]] {{The Who}}.
** They combine a couple of notable genres, most notably math rock.
* PowerWalk : In each of the three endings, the girls do this, although a bit differently each time. In 'Don't Say Lazy', the four original members do it together in their (much loved, according to fan art) Goth-Lolita outfits. In 'Listen!!', the five members of Afterschool Tea Time after the addition of Azusa do this inside the cake. In 'No, Thank You!', the five girls are all present doing this amidst a field of H's and T's, although this is the only time they are not together as a group, and also the only time they are wearing school uniforms (although they've all changed by the time the chorus comes; also note that the school uniforms worn are '''not''' the uniforms of Sakuragaoka). It is possibly worth noting that in each of these cases, the girls are walking right to left.
* PuniPlush : Very noticeable, in some scenes more than others. Listen to Yui exclaiming "Puni! Puni!" as she squeezes Mio's callused fingers. The art style as a whole is a lot more 'squishy' with less consistency of form than most anime and while it tends to make most movements look more fluid than they really are it also leads to noticeable distortion during in-between frames. This is most noticeable with characters' fingers which are also more extensively animated than in an average anime.

[[folder:Q to T]]
* RealPlaceBackground : The anime's settings are based on [[http://infinitemirai.wordpress.com/2012/05/01/map-of-kyoto-k-on-style/ actual locations in Kyoto]]. The school building is modeled after a renovated elementary school in Toyosato, Shiga Prefecture, which isn't that far from Kyoto either.
** CaliforniaDoubling : However, the fact that they have to pass Mt. Fuji on the bullet train to get to Kyoto indicates that the setting is supposed to be in the Kantou region.
* RecycledINSPACE : It's ''Anime/LuckyStar'' [[foldercontrol]]

[[folder: WITH GIRLS! ]]

* RecurringExtra: The Occult Club.
* RedOniBlueOni : Ritsu and Mio.
* [--[[IncrediblyLamePun My Love Is]]--] TheRedStapler : Sales of Fender instruments rose thanks to the show.
** Yui plays a Gibson Les Paul, but those are a ''lot'' more expensive, so the sale of [[PoorMansSubstitute Les Paul ''clones'']] went up considerably.
*** Which is of course helped by shops [[http://static.tvtropes.org/pmwiki/pub/images/kon-music-shop_2648.jpg using the show's imagery]] to sell them.
** Let's not forget that blue-and-white striped rice bowls were actually made.
* RefusalOfTheCall : Mio ''really'' doesn't want to be Romeo for the school play, except, she [[{{ButThouMust}} doesn't have a choice.]] Used in conjunction with the FiveStagesOfGrief for [[{{PlayedForLaughs}} the lulz.]]
** Also [[{{Tomboy}} Ritsu]], who must play Juliet. Of course, things could have been easier if Mio and Ritsu just switched roles. {{Lampshaded}} by Yui, who suggests they [[{{PersonalitySwap}} switch personalities.]] Because that would be ''[[{{SarcasmMode}} waaaaaay easier.]]'' [[{{WriterOnBoard}} Trope is definitely]] [[{{EnforcedTrope}} Enforced.]]
* RiddleForTheAges: The manga ended without revealing what subject Ritsu is majoring in at the university, saying only that Ayame is in the same department. The only major to be confirmed is Yui's, in education; it's safe to assume Mio is studying literature and we can guess Mugi is in business and/or music. Because of Ritsu's cooking skills, some fanfic authors assume she's studying to be a chef.
* RightBehindMe : In season 1 episode 10, when Azusa is telling Ui what she thinks of her new friends in the light music club, she proceeds to call Ritsu irresponsible and sketchy... at which point Ritsu replies from the seat immediately behind Azusa.
** It's actually Ritsu who asks what Azusa thinks about Ritsu, as she had been listening in on the conversation. Ritsu's ability to imitate other people and intrude into their inner monologues is a running gag in both the manga and anime.
* RomanticTwoGirlFriendship : By the latter half of the series, it's hard to find ''any'' friendship among the main cast and supporting characters that hasn't been romantic (or at least loaded with a planet's worth of LesYay) in some way.
* RubberFace : Sawa-chan does this to Ritsu during episode 4 of Season 2 after the latter mentions that the former is much scarier without make up on.
* RunningGag : In the manga, Yui's wish to be able to snap her fingers turn up at various times.
** The statue of the school founder keeps getting new accessories.
** ''(Azusa shows up with a tan)'' "Who are you?"
** Mugi carrying heavy objects without any strain. Not exactly a gag, as it isn't commented on much.
*** She did beat that arm-wrestling machine in S2-[=EP14=] literally single-handedly.
** Barnacles.
** Ui's resemblance to her sister is quickly becoming this.
** Someone is hiding behind the club room's door, secretly watching what happens on the other side, and falls down (or is hit by the door) when the door is opened. (Examples: S2 07 04:29; S2 16 08:08; S2 22 16:39)
*** Carried over into one chapter of the restarted manga; at the start of said chapter, Yui opens her door, slamming it into the face of Akira, who was left with the rather unsavory task of waking her up. At the end of the chapter, Yui opens her door the next day and [[BookEnds slams it into Akira and Ritsu's faces.]] "Some doors are more dangerous to stand in front of than others'" indeed.
** When the band is hanging out in either the club room or Yui's house, Sawako-sensei has a tendency to appear without anyone else noticing, usually with Ritsu shouting, "Wait, when did you get here!?"
* SaveOurClub : At the start of the series, the club has no members whatsoever and needs to basically be rebuilt from the ground up.
* SayMyName : A cute, roundabout version occurs in ''Cagayake GIRLS!'':
-->''Mugi: "Uuuuuu~Yui!"''
-->''Yui: "Azusa~!"''
-->''Azusa: "Mi-o!"''
-->''Mio: "Riiiiitz!"''
-->''Ritsu: "'''MU! GI!!!'''"''
* SceneryPorn : What you get when you hire [[KyotoAnimation KyoAni]] to do a [[strike:school trip episode taking place in Kyoto]] high school show taking place ''anywhere''.
** Ohoho. Wait 'til you see the movie.
* SchoolFestival : Three of them, [[CrowningMusicOfAwesome all of them including concerts]].
* SchoolgirlSeries
* SchoolPlay : With Mio and Ritsu as RomeoAndJuliet.
* {{Sensei-chan}} : Sawa-chan.
* SeriesContinuityError : In the second season, Azusa is told about Megumi Sokabe, the former StudentCouncilPresident. According to the flashback, she's two years older than the main four girls, and therefore graduated when they finished their first year. However, she made a quick cameo appearance in episode 11, where she talked to the Light Music Club, which at that point in time also included Azusa...
** {{Retcon}} : When we first see Megumi in the first season, she's wearing a green ribbon, indicating that she's one year ahead of Nodoka. However, in the flashbacks from the second season, she has a red ribbon, which means she was two years ahead. (After her class graduated, the incoming first-year class, which included Azusa, was next to use red ribbons.)
** In season 2 episode 13 (15:05), Azusa complains that Yui still hasn't learned to read music, which is consistent with the manga, but in a scene created for the anime in season 1 episode 10, Yui was reading a score while practicing guitar in the middle of the night.
* SeriesFauxnale : At the end of the first season, Yui reflects on how much she's grown from the person she was at the beginning of the show, and the band performs at the school festival, exclaiming "This is our Budokan!". A change from the manga, where Yui's cold results in the performance being quite bad, so as to make the last episode more satisfying. Then the second season gets announced, and the episode is pretty much {{handwave}}d.
* SeriousBusiness : The strawberry on top of a slice of cake.
** Rice cakes as well.
** In the case of Light Music itself, despite this being a series about playing in a band, this trope is a bit subverted in that most of the time, the club doesn't really take its band practice all that seriously.
* SexyDiscretionShot : Done when Mio stumbles and bares her panties. Only in the anime, though.
* SexySantaDress : Sawako first puts Yui in one, but changes her focus to Mio when Yui turns out to like it. In the anime, the design is changed from a [[BareYourMidriff two-piece]] to being a big, shoulder-revealing [[SweaterGirl sweater]].
* ShipTease - Read the entry for "LesYay" on this page.
* ShapedLikeItself : Happens several times.
** Yui: [[http://www.youtube.com/watch?v=nz32WHGPXMI "Fun things are fun."]]
** Yui: "Look at these screws! They're all screws!"
*** In fact, she meant "The whole shelf is nothing but screws".
** Yui again (S2 16 19:16): "Well, I think Azunyan is Azunyan. Ricchan is Ricchan. Mio-chan is Mio-chan. Mugi-chan is Mugi-chan."
** "Afterschool Tea Time will always, always be... ''after school!"''
* ShoutOut
** Johannes Krauser II. from ''DetroitMetalCity'' makes an appearance in one of Yui's delusions in Episode 1.
** "JimiHendrix?" "Jimmy Page?" "Jeff Beck?!"
*** ''(Are there really that many guitarists that start with "J"?!)''
*** When Azusa plays guitar the first time images of [[Music/LedZeppelin Jimmy Page, Robert Plant]] and [[Music/{{Nirvana}} Kurt Cobain]] (all wearing Azusa's pigtails) can be seen.
*** When the music store clerk tells the history of Sawako's guitar, images of Music/EricClapton, [[Music/{{ACDC}} Angus Young]], [[Music/BlackSabbath Tony Iommi]] and [[Music/TheWho Pete Townshend]] are shown, along with a SuspiciouslySimilarSong of respective guitar riffs.
** The MusicVideo that plays during the school festival concert suggests an outlaw concert like Music/TheBeatles' rooftop concert, with a little ''ThelmaAndLouise'' thrown in as well.
*** Speaking of the Fab Four, did anyone notice that Mio is a left-handed bass player? [[Music/PaulMcCartney That sounds strangely familiar...]]
** Yui hugging Azusa to calm her down has a high resemblance to Kyou's {{glomp}} on Kotomi in ''VisualNovel/{{CLANNAD}}'' (another show by the same studio), especially with the [[http://static.tvtropes.org/pmwiki/pub/images/Kyou_-_get_to_know_Kotomi_better.jpg the "good girl" part]]. It also occurs in the manga, which might be mere coincidence, but KyotoAnimation sure picked up on it.
** [[http://fabien.li/tvtropes/K-ON!%20-%2014%2020.23.jpg Azusa and her tora-mimi]] are reminiscent of Kisa from ''FruitsBasket''.
** A cheeky homage to the "I'm flying!!" scene (complete with GratuitousEnglish) from ''{{Titanic}}''. (S1 10 08:03)
** All of the recurring characters share their respective last names with members of {{P-Model}} or ThePillows.
** In episode 4, Mio is looking through a box of old club members stuff, and finds a score book of [[Music/BlackSabbath Ozzy Osbourne]].
** In one episode, it shows a clip of Sawako playing guitar with her teeth - an obvious reference to Jimi Hendrix.
** [[TheWho "ZA WHO."]] More specifically, Keith Moon, one of the reasons Ritsu took up drumming. When Ritsu mentions him in the club, Azusa asks if he's the guy who blew up his house with fireworks.
** Yui is seen imitating Pete Townshend's windmill strumming move from time to time.
** Sawako-sensei's white Gibson Flying V may be a shout out to ''TheLegendOfBlackHeaven'', where the same guitar is the signature instrument of another has-been ex-rocker, Oji "Gabriel" Tanaka.
** Kamakiri, the band with the left-handed guitarist who catches Mio's attention during the outdoor music fest, might be a shout out to [[http://www.steelydan.com/lyrkama.html#track1 Donald Fagen]].
** [[RoseOfVersailles "Oscar!"]] (with [[http://static.tvtropes.org/pmwiki/pub/images/K-ON_Ep__14_-_Lady_Oscar_reference_2609.jpg screenshot]])
** Less obvious, but in the third ending theme ("No, Thank You"), there's a shot where Mio puts her thumbs and index fingers together and in the gap between her hands, there's a shot of the sky. A similar hand-portal effect was used heavily in the video to "Shut Up and Let Me Go" by The Ting Tings.
** Also, some parts of the music in K-On are [[SuspiciouslySimilarSong not too dissimilar]] to those in certain Music/{{Metallica}} songs. [[http://www.youtube.com/watch?v=nEUILRi_jLk For example, the solo in Fuel and Yui's solo in Fuwa Fuwa Time, amongst others.]]
*** The same person uploaded a [[http://www.youtube.com/watch?v=QUHH0mGmTPs sequel]] that includes songs from the second season.
** The little frog statue in front of the club room [[http://static.tvtropes.org/pmwiki/pub/images/kon-kamichu_9716.jpg looks an awful lot like a similar statue]] in ''{{Kamichu}}''.
** [[http://frostii.com/2010/09/20/k-on-24/ Evidently]] Nodoka is a [[Franchise/StarTrek Vulcan]], not the biggest surprise with her unflappable demeanor.
** From the dub: "[[Film/TheExorcist The power of cute compels you!]]"
** When Yui fills in for Sawako in Episode 10 of season 2, her Gitah is decorated with SpikesOfVillainy on the headstock and target-shaped lines across its body, ala [[Music/{{Slayer}} Kerry King]] and [[Music/BlackLabelSociety Zak Wylde]].
* ShownTheirWork : The instruments played by the girls are all existing models in the real world:
** Yui plays a Heritage Sunburst Gibson Les Paul Standard Classic:not bad at all for a first guitar.
*** She apparently strings it with D'Addario XL Nickel Round Wounds. And those really don't rust.
** Mio provides the low frequencies on a left-handed 3-Color Sunburst Fender Jazz Bass (likely Japanese) in the anime, and a Fender Precision in the manga, both four-string. The bass she swoons over in the anime is a five-string left-handed Music Man Stingray:good taste there!
** Mugi's keyboard is a Korg Triton Extreme (likely the 76-key version since she mentions it in her ImageSong). Its built-in valve circuit features prominently in the opening credits. In "No thank You" the second ending of the second season, she plays a Hammond organ.
** Ritsu [[IncrediblyLamePun bangs]] around on what looks like a Yamaha Hipgig Rick Marotta drum kit with Zildjian cymbals.
** Azusa made a fine choice with her Cherry-red Fender Mustang, since its short scale is a nice fit for her small hands.
** Several of the random items (such as the tea sets or Mio's headphones) are also recognizable (and very expensive) real world products. Mio's headphones are the [[http://www.akg.com/personal/K_701,pcatid,4,pid,1,_psmand,1.html AKG K 701]], for example.
*** It even goes so far as to include their clothes: the [[http://static.tvtropes.org/pmwiki/pub/images/Mio_TUK_shoes_1604.jpg shoes Mio wears]] during the "No, Thank You" ED (second season) are [[https://www.tukshoes.com/store/index.php?main_page=product_info&products_id=327 T.U.K. A6803 white leather Mondo-sole creepers]].
* ShrinkingViolet : Mio at times, especially when spooked or embarrassed by Ritsu.
** Curiously, Ritsu's younger brother Satoshi tends to go into hiding when the other girls visit Ritsu's home.
*** The club holds interviews from random students and faculty for their promotional video, and the student they talk to in the library appears to be this.
* ShyBlueHairedGirl : Azusa with her blue-black hair and her trepidation for {{Cosplay}}.
* SiblingIncest: One of Ui's {{Image Song}}s is titled "Lovely Sister Love" and contains the line "Onee-san daisuki" ("I love my big sister").
** Ui's infatuation with her ''Onee-chan'' is rather clearly shown in the {{anime}}. It's just that it hasn't reached critical romantic intentions.
*** See LesYay above.
* SickEpisode
* SidetrackedByTheAnalogy: : Yui. Full stop.
* SillyMeGesture : Combined with HandBehindHead by Yui and Sawako-sensei in episode 5.
** Sawako does it again after she spent the night before the summer festival partying instead of sleeping.
** And ''again'' in the penultimate episode when she is complimented on her video editing skills.
* SleepCute : ''All'' the girls of the band do this together after a concert.
** Mio and Ritsu do it on the [[http://static.tvtropes.org/pmwiki/pub/images/k-on_sleep_cute_976.jpg title card for the second chapter of Vol. 3]], while sharing earphones.
* SleeperHit : The original {{Yonkoma}} was virtually unknown before being turned into an anime.
* SliceOfLife : Music-playing aside, this show is basically about cute girls doing cute stuff.
** Which even gets throttled to almost ''{{Piano}}''-like levels in the second season. Episode 13 is mostly about Azusa and her friends being ''bored'', for instance.
* SmashingWatermelons : Mio does this [[http://static.tvtropes.org/pmwiki/pub/images/K-On_melon_3257.jpg in the manga]]. In the anime adaption, she brings the watermelon with the same intention, but realizes that they can't spend all of their practice time goofing around on the beach.
* SoundOff : An attempt to use their own songs during a marathon fails when the songs turn out to be too fast.
* SpitTake : Satoshi's reaction to hearing that [[{{Tomboy}} his sister]] is going to play [[RomeoAndJuliet Juliet]].
* ASpotOfTea: Thanks to Mugi's splendid tea set (a present from the Royal Family of Finland) and her family's near endless surplus of cakes from friends and well wishers, the ''Afternoon Teatime'' school-band of KOn binds their friendship through a spot of afernoon tea before and after practice.
* {{Squee}} : Ritsu does this twice in the first episode, learning Mugi has joined her club, and first meeting "expert guitarist" Yui for the first time.
** The whole audience watching Class 3-2's production of ''RomeoAndJuliet'' squees at Ritsu and Mio performing the balcony scene.
* StandingInTheHall : Mugi insists on being punished this way, since she considers it an essential part of a regular high school experience.
* StealthHiBye : Sawa-chan does this occasionally, either in the club room, or Yui's house. The girls, particularly Ritsu, are usually surprised at her sudden appearance.
* StealthPun : Yui wears a giant chicken suit when trying to gain new members for the club, and underclassmen flee before her in terror. While "chicken" in Japanese is ''niwatori'', the word for molester is... ''[[TheChikan chikan]]''.
** Does that also count as a BilingualBonus VisualPun?
** Another one: The last names of the band members spell THANK, as seen in the second season's second ed.
*** In the scene where they all line up in the ED, their positions spell KNAHT from their last names, which is THANK if you read right to left, like a JDM audience.
* SuspiciouslySimilarSong - The tracks "Virtual Love" and "Pinch Daisuki!" sound suspiciously similar to "Das Model" by Music/{{Kraftwerk}} and "Popcorn" by Hot Butter respectively. Not that that's a ''bad'' thing, mind.
* SuspiciouslySpecificDenial
** Azusa, when Ui asks her what she was pondering about: "I wasn't thinking about Valentines or anything like that" (S2 22 01:17)
** Sawako is quick to point out that the reason she's no longer a homeroom teacher is certainly not that the school thought she did a bad job with the last class.
* SweatDrop
* SweetDreamsFuel
* SynchronousEpisodes : The episode Field Trip! [[ExactlyWhatItSaysOnTheTin follows the third year class on their trip]] to Kyoto. The following Staying Behind! shows what the second year students were doing during the same time. A phone call between Yui and Azusa is shown from both point of views.
* TagTeamTwins : While not twins, Ui takes her older sister Yui's place in band practice when Yui catches a cold, attempting to fool the other band members. See TwinSwitch below.
* TalkingInTheirSleep: Most frequently Yui, though Ritsu gets in on it too during their second training camp.
* TanLines : Azusa tans REALLY easily, which is embarrassing for her when she goes to the pool right after spending a day in the mountains.
* TaremeEyes / TsurimeEyes : The art style has everyone (yes, even Yui) toggling between these two types of eyes, but it's most noticeable with Sawako, showing how wild she's currently being.
** When Yui does an impression of Mio in the manga, she uses her fingers to physically push her eyes into the Tsurime shape for one panel.
* TeamPet : Ton-chan, the pig-nosed turtle.
** Azu-nyan also is treated as such by everyone but Mio when she first joins the club.
* TechnicianVersusPerformer : A veeeeery mild example between Azusa (technician) and Yui (performer). Azusa knows much more about guitars and playing technique, with years of experience, but Yui has a natural talent for most instruments and perfect pitch.
* TechnologyMarchesOn : A cassette recorder is used to record the band's complete song list, of all things.
* TeruTeruBozu : Yui makes a bunch of them and hangs them upside down in hopes of getting rain the next day. It doesn't work.
* ThePiratesWhoDontDoAnything : Almost none of their time (be it Yui's class or Ui's class) is spent practicing as a band. There's been one concert during the entire run and it was off screen.
** Azusa even acknowledges and doesn't comprehend the fact that they don't practice when she first joins. She even attempts to start on her own only to be yelled at by Sawako for attempting to play! The rest of the episode is a clash between them attempting to do actual band things and just goofing off like they always have.
* ThemeNaming: Except for Sawako, ''every'' character has a name written with just one kanji.
* ThemeTwinNaming : Yui and Ui. While they are not twins since Ui is a year younger than Yui and have different hairstyles, they look very alike. In fact, Ui poses as Yui during band practice in Episode 12 of the first season when Yui has a cold. See TwinSwitch below.
* [[ThoseTwoGuys Those Two Girls]]: The occult club.
* TomboyAndGirlyGirl : Ritsu and Mio. Especially in the flashback to elementary school, with brash, {{Shorttank}} Ritsu and shy, dress-wearing Mio.
* TrailersAlwaysLie : The next episode previews intentionally feature snippets of dialogue that never convey what the episode is actually about. For instance, Season 2 Episode 18's preview made it look like Mio was serious about moving to Irkutsk, when it was just one of her increasingly lame excuses to get out of starring in the class play.
** To be fair, most of the time the titles are ExactlyWhatItSaysOnTheTin, and most other episodes play it straight.
* TrueCompanions
* TwelveEpisodeAnime : The first season's main StoryArc spans twelve episodes. Episode 12 was labeled as the "finale," causing some people to think it would actually be the last one (It was, until the announcement of Season 2, which is why it was very finale-esque). There is an Episode 13 and 14, but they lie outside the story arc.
* TwinSwitch : When Yui gets sick before the concert, Ui lets her hair down and goes in her place. [[spoiler:She fools everyone for a while, but Sawako-sensei eventually sees through her disguise as she is better "endowed" than her OLDER sister. Curiously, nobody wonders why Yui would suddenly don the red UsefulNotes/{{inside shoes}} worn by first years.]]
** A similar event occurs again: Yui is shown packing things for her Kyoto trip and declaring that everything is all set... and then ties up her hair. Ui was packing for her sister, and then proceeds to wake up Yui, who is sacked in her bed. And in S2 E23, we see Ui ironing... but it's actually Yui.
** Yui uses Ui's picture for her summer school ID card.
** Milked for all it's worth in episode 21, where Yui is trying to decide which hairstyle to use for her yearbook picture. That includes having Ui model for her, and this being Yui, she forgets to take her hairpin back, and Ui ends up wearing it for the morning. Everyone comments how identical the sisters are once Ui lets her hair down. Bonus points when Azusa sees it, and Ui hugs her from behind saying ''Azu-nyan!'' in the '''cutest voice ever heard'''.
** Used once again in the second chapter of the new manga, [[spoiler:when Ui tries to convince Azusa that she was really Yui come back to check up on the club. Azusa and Jun actually start to buy it until Ui is "outed" again by Sawako-sensei in the same way as the first time (i.e. Sawa-chan noting the difference in chest sizes).]]
* TwoLinesNoWaiting : The current structure of the manga, serialized across two magazines. Chapters covering Yui, Mugi, Mio and Ritsu's first year at university alternate with those about Azusa, Ui and Jun's last year at high school, and it is expected that they will be published in this order in the tankoubon.
[[/folder]]

[[folder:U to Z]]
* UnlimitedWardrobe : When not in school uniforms, the girls pretty much never wear the same clothes twice.
** With only a single exception at the end of the second BeachEpisode, where Azusa is wearing the same outfit when she met Ui at the beginning of the episode, only with a tan.
* UnmovingPlaid : In the manga, both Mio's and Yui's pajamas are drawn like this.
* TheUnreveal : In episode 3 of the second season, Sawako's attempts to look younger "goes too far", which results in her wearing a face mask and sunglasses to school. She shows her face to Yui and Ritsu, but viewer only sees the back of her head.
* VacationEpisode : TheMovie involves Hokago Tea Time taking a trip to London.
* WeightWoe : Mio and Mugi always have issues about their weight gain at the end of the year. Ritsu shows shades of this in the first training camp episode.
* WhatWereTheySellingAgain : Mentioned; when the band wants to make a recruitment video for the Light Music Club, Mio is concerned that the video will have ''nothing'' to do with the club if they go with the "narrated by Ton-chan" angle.
* WhipPan : [[http://www.youtube.com/watch?v=yl1safFRrfE This funny scene.]]
* WikiRule : [[http://k-on.wikia.com/wiki/K-ON!_Wiki Would you believe it?]]
* WingdingEyes : Many of the light music club members have done this, often with golden stars in their eyes.
* WithFriendsLikeThese[=/=]VitriolicBestBuds - One wonders why Mio still considers Ritsu her friend, with the teasing, humiliations and blackmailing and all...
** She gets back at Ritsu through violence. See CranialEruption above.
** During her brief stint as a waitress, Mio tries pretending all the customers are her friends to overcome her shyness. Problem is, even the ''imaginary'' Yui and Ritsu irritate her.
* XMeetsY : ''Anime/LuckyStar'' meets ''[[Manga/{{Beck}} BECK: Mongolian Chop Squad]]''
** In which case, it would be ''{{Peanuts}}'' [[ThisIsYourPremiseOnDrugs on LSD]] with even more crack meets ''Manga/{{Beck}}''.
** Considering how heartwarming and feel-good the show is, it can also be called "''Manga/AzumangaDaioh'' starring ''Music/TheBeatles"'' (To which the original 4 girls have analogous roles and personalities to.)
** Alternatively, ''LightNovel/HaruhiSuzumiya'' meets ''DetroitMetalCity''.
** ...or ''LightNovel/HaruhiSuzumiya'' meets ''Anime/LuckyStar'' meets [[JapanesePopMusic J-Pop]].
** A more extreme example is ''Anime/LuckyStar'' meets ''{{Metalocalypse}}''.
** This troper likes to call this series ''Manga/AzumangaDaioh'' meets ''TheCommitments''.
* XtremeKoolLetterz : Love Crysis. A (possible misspelled) poster in TheMovie even spells is "Love Crycis".
* {{Yonkoma}}
* [[YouAreATreeCharlieBrown You Are A Tree, Hirasawa Yui]]: Yui was cast as "Tree G" in the class play.
-->'''Azusa, counting''': A, B, C, D, E, F... Do they really need that many trees?
** Oddly enough, Yui seems to get as much stage time as the lead players.
* YouGottaHaveBlueHair : Averted in the main cast and a large part of their classmates, who have black, brown or blonde hair. However, among the many unnamed first and second year students, green and blue hair colors show up more often.
* YourDoorWasOpen : Played for laughs. Occasionally, Sawako-sensei suddenly drops in unnoticed when it should be logically impossible for someone not to realize she came in, usually when she was neither invited or ''informed'' of the get-together beforehand. Ritsu is usually the one to make a note of this, saying "Wait, when did you get here?" or "You were sitting here the entire time?!"
