'''Waiter:''' Ah yes. But now I have a red tuba which makes you shit yourself!
-->-- ''Series/ThatMitchellAndWebbLook''

A type of FunctionalMagic that works via music: playing a certain song or a magical instrument that causes a spell-like effect to happen. This may have derived from the premise of there being legitimate power within the words one uses, which is somewhat akin to [[LanguageOfMagic true name magic]] in this regard.

A WanderingMinstrel, MagicalFlutist or [[TheMusicMeister Music Meister]] may have this as their main method of fighting. The MusicalAssassin uses a particularly nasty variant. Often shows up as a kind of MindControl, or also commonly it can buff allies in a justified ThemeMusicPowerUp.

Villains who use magic like this are often foiled by would-be victims [[DisabilityImmunity who are hearing impaired.]]

Recently, ocarinas have become popular for this, perhaps because of its ancient history, or its simple, yet exotic sound. Or maybe it's because [[Franchise/TheLegendOfZelda Link]] [[TropeCodifier used one]] in ''VideoGame/TheLegendOfZeldaOcarinaOfTime''. It certainly doesn't hurt that they are easily portable which justifies their use in a more action-packed adventure.

Speaking of "ancient history," this trope is definitely OlderThanFeudalism (the tales of Orpheus date as far back as 5th century BC) and possibly OlderThanDirt.

DiscoTech is the tech equivalent. Compare with ThePowerOfRock, BrownNote and MagicDance. Also see the SubTrope, MindControlMusic.



[[folder:Anime & Manga]]
* ''Anime/OjamajoDoremi'' probably has the most musical references and motifs of any anime series. Even the magical sparks are shaped like musical notes.
** When the witches reach a certain level, their "Poron", or wand, is fused with a musical instrument of their choice. When casting magic, a tune played with said instrument can be heard. In fact, most magical artifacts play short musical tunes in-universe when used, including the transformation taps.
* ''Franchise/DragonBall''
** There was a magical ocarina in the thirteenth ''Anime/DragonBallZ'' [[TheMovie movie]]. [[spoiler: It can potentially be used to either seal or unseal the BigBad.]]
** In ''Anime/DragonBallGT'', the [[TerribleTrio Para Para Brothers]] used speakers that were built into their body armor that would cause their opponents to dance non-stop, thus leaving them vulnerable to attack.
* ''Manga/ViolinistOfHameln'', a {{Shonen}} parody manga based on the Pied Piper about a guy with a {{BFS}} version of a violin who fights demons with magical music. Classical music has never been so badass.
* In the ''Manga/AhMyGoddess'' manga and movie, particularly powerful and/or complex magical effects can be accomplished through singing (such as the reversal of a spell with both heavenly and demonic components and the recreation of the ''TheWorldTree''), often but not always in combination with HermeticMagic.
* In ''Anime/RahXephon'', both the title mecha and its enemies the Dolems utilize singing as an attack method.
* From ''Manga/OnePiece'':
** [[DemBones Brook's]] attacks after the TimeSkip count as an example. While the power doesn't come from the music but from the power of his [[PowerUpFood Devil Fruit]], he can use his music to "move people's souls" effectively influencing them (e.g., made them believe they are in a party instead of a battle). Even before then he demonstrated the skill to lull people to sleep with a gentle lullaby even while they were in pitched combat (unless that was an early demonstration of the same "soul moving" power).
** Seems to be behind Scratchmen Apoo's powers as well. He can turn his own limbs into musical instruments and play notes that cause explosions or RazorWind.
* ''Anime/{{Macross}}'' introduced in later series the concept of Fold Waves and Fold Receptor Factors. The former are superdimension waves that form the basis of the series' FasterThanLightTravel and [[SubspaceAnsible communications]]. The latter is the discovery that certain people have the ability to sense and produce these, usually while singing. Specific examples follow:
** ''Anime/SuperDimensionFortressMacross'': It's debatable whether Minmay's effect on the Zentraedi is a product of Fold Waves or just cultural exposure, but Expanded Universe materials have given Minmay a powerful Fold Receptor Factor.
** In ''Anime/MacrossII'', the Marduk have developed their own morale-boost-giving singers, the Emulators. The plot gets definitely kickstarted when one of them, a girl named Ishtar, is retrieved by IntrepidReporter Hibiki and starts learning about humanity...
** ''Anime/{{Macross 7}}'' has this (called "Song Energy" in series) as a fundamental part of the premise. The alien [[OurVampiresAreDifferent life energy draining]] antagonists ("Protodeviln") experience literal pain when exposed to music, due to the protagonist's "Anima Spiritia". Sure, it's not genuinely magical, but you wouldn't know that from the laser speaker pods and light show Fire Bomber puts on. And the ultimate resolution of this is that, right at the last moment before the leader of said aliens [[PowerIncontinence uncontrolably]] sucks out the life of the entire galaxy, the protagonist sings at them so hard that the species learns that they can generate their own life energy by singing, then decide to move on to another dimension.
** Sharon Apple, the [[AIIsACrapshoot artificial idol]] from ''Anime/MacrossPlus'', took control of the Macross' computer network and sang ''mankind'' into a blissful stupor. Granted, she was given the tools to do exactly that by one of her creators... while the other, female lead Myung, is stuck trying to fight her.
** ''Anime/MacrossZero'' has the quasi-magical effects of the female lead's singing explained through Fold Receptor Factor: the rocks she levitates contain Fold Quartz, and the Protoculture superweapon known as "the bird-man" runs on it. She herself is genetically inclined to have a high fold Receptor Factor specifically attuned to the "bird-man".
** ''Anime/MacrossFrontier'' explored Fold Waves more fully: it introduced Fold Quartz (a mineral that reacts to Fold Waves), and Ranka [[spoiler: as well as Sheryl]] is able to communicate with the Vajra, at least on a basic level, through her songs thanks to this phenomenon.
** ''Anime/MacrossDelta'' has as a central premise the main cast combating a HatePlague through song. All the singers of the [[IdolSinger idol]] [[GirlGroup group]] Walkure have a high Fold Receptor Factor. Additionally, it turns out that [[spoiler:said Hate Plague itself is activated by the singing of Windermere's Wind Singer]].
* Diva's song from ''Anime/BloodPlus''. It's beautiful, it's heart-breaking, and it [[BodyHorror transforms innocent people]] into ''[[OurVampiresAreDifferent horrible bloodthirsty bat-demon-things]]''. It's worth noting that her song is mainly the ''catalyst'' for the transformation; the potential is given by having people unknowingly digest her processed and altered blood.
* ''Anime/{{Pokemon}}''
** In ''[[Anime/{{Pokemon2000}} Pokémon: The Movie 2000]]'', playing a specific song on a specific ocarina can heal Lugia, no matter how far away he is, as well as calm the feud between the three legendary birds.
** In ''Anime/PokemonTheRiseOfDarkrai'', there was that song that made everyone who could hear it calm, even [[spoiler: Dialga and Palkia]].
** In ''Anime/PokemonRangerAndTheTempleOfTheSea'', Manaphy's singing can calm water pokemon and gain access to The sea temple.
* In ''Anime/CorrectorYui'', Yui and her friends Haruna, [[ThoseTwoGuys Reiko and Akiko]] were rehearsing a song for their SchoolFestival. it becomes a plot point later, when [[spoiler: Yui's IKnowYouAreInThereSomewhereFight speech to a BrainwashedAndCrazy Haruna includes her singing the same song instead of fighting her, breaking through Haruna's brainwashing an reverting her back to who she usually is.]] Later, [[spoiler: Professor Inukai uses Yui's singing as a part of his battle strategy against the BigBad, who is weak against certain sounds, and Haruna returns the favor to Yui by singing the song to her when she's about to lose the battle against Grosser, giving Yui her strength back so she can keep on fighting.]]
* The Dantists in the world of ''VisualNovel/ShinkyokuSoukaiPolyphonica'' specialize in magic music to calm spirits.
* In ''Anime/ALittleSnowFairySugar'', the Season Fairies control the weather with magical instruments.
* ''Manga/{{Naruto}}''
** Menma, in a filler, obtained various effects, including repelling fire and smoke and boosting Naruto's strength, by playing an ocarina.
** Tayuya, who can control three summoned demons and cast illusions by playing tunes on her flute.
* ''Manga/MermaidMelodyPichiPichiPitch''. Most MagicalGirl anime have some fighting scenes where weapons, beams of energy, balls of light, or what-have-you are the norm. This one has [[MagicIdolSinger idol singers]]... singing their songs against their opponents.
* All over the place in ''Manga/MyBrideIsAMermaid'', as magic music is apparently a [[OurMermaidsAreDifferent mermaid's]] greatest ability.
** There's a song that causes all listeners to engage in bloody combat, a song that acts as the main character's ThemeMusicPowerUp, a song that puts everyone to sleep, and a song that causes everyone within earshot to dance uncontrolably.
** There was also that incident when both Sun and Lunar were singing at the same time, which caused all humans present (except Nagasumi) to... well, we don't know, because every single person was covered under a wall of Censor buttons.
* The manga version of ''Manga/{{Pretear}}'' gives Sasame, the Knight of Sound, the ability to play any musical instrument--and he also seems to be able to soothe people by improvising songs to sing their feelings back to them.
* Azmaria Hendrich from ''Manga/ChronoCrusade'' has the power to heal anyone who hears the song she sings. In the manga, ''all'' of the Apostles have the ability to control the Astral Line through music--all of them are shown singing, except for Joshua, who channels his powers by playing an OminousPipeOrgan instead.
* Aria of ''Manga/TegamiBachi'' has the ability to heal people's hearts with music played on her violin.
** It works on [[TheHeartless Gaichuu]] as well.
* The first two seasons of ''Anime/OnegaiMyMelody'': the magic powers of My Melody and her rival Kuromi are recharged through music, and each season centers around one musical instrument that brings about the end of the world.
* When Amiboshi of ''Manga/FushigiYuugi'' takes out his flute, be thankful if he's on your side. If he's not, ''run''.
* ''Anime/MonColleKnights'' has Utahime/Kahimi (whose song causes gigantic moving plants to grow) and the Merboy Choir (whose songs cause tidal waves and transformation).
* Bolorenof in ''Manga/HunterXHunter'' combines this with MagicDance: His body has holes in his flesh that, when he dances, vibrates the wind going through them, making him a woodwind instrument. When dancing in certain ways, he produces songs that summon things to attack for him.
* [[{{Bishounen}} Fai D Fluorite]] of ''Manga/TsubasaReservoirChronicle'' can [[spoiler:summon up a magic shield]] by whistling.
* In ''Anime/YuGiOhZEXAL'', Yuma uses three Xyz Monsters called Djinns, cute-looking Fiend-Type monsters that use music to fight opposing monsters. (There are actually ''four'' of these monsters in the card game, but Yuma has yet to use one of them.)
* ''Anime/SuitePrettyCure'' is an installment of the ''Franchise/PrettyCure'' series that revolves around this.
** ''Anime/PrettyCureAllStars: Everyone Sing - Miraculous Magic'' has a very interesting case. [[Anime/MahoGirlsPrecure Cure Miracle and Cure Magical]] are constantly lured around by a mysterious song, which they end up finding being hummed by the younger version of the movie's BigBad. She never understood the meaning of it except that her teacher used to sing it to her all the time. [[spoiler:At the end of the movie, she realizes it's the ultimate magic she sought for so long - her teacher had given it to her and she was so blinded by her desire for power that she never realized she already had it. She ends up using it to empower the 11 teams of Cures]].
* Reiko's power in ''VideoGame/GateKeepers'' is half using this, half being a MasterOfIllusion.
* In ''LightNovel/LogHorizon'', players of the Bard class in the [[MassivelyMultiplayerOnlineRolePlayingGame MMORPG]]-turned-reality ''Elder Tales'' are able to utilize music to buff their allies or de-buff their enemies for set duration of time.
* In ''Anime/CrossAnge'', a [[SuperPrototype Ragna-Mail's]] GoldenSuperMode is activated by singing certain songs. It's also the way for a pilot to access the powerful [[WaveMotionGun Spacetime Convergence Cannon.]]
%%* Vidaldus from ''Manga/FairyTail''.

[[folder:Comic Books]]
* ''Blockheads'' is about a young rapper who bends reality with his magic rhymes.
* The Fiddler, Golden Age baddie from Creator/DCComics.
* The Pied Piper, ComicBook/TheFlash foe (and later ally) from DC.
* ''ComicBook/{{Phonogram}}'': Magic is intricately bound up within pop music, and "phonomancers" are magicians who can tap into this for power.
* The original ''[[Franchise/TheSmurfs Smurfs]]'' comic book story ''The Smurfs and the Magic Flute'' had the title flute.
* Creator/NeilGaiman's ''How to Talk to Girls at Parties'' has a poem that is either magical or [[ClarkesThirdLaw eldritch science so advanced it might as well be]], which walks up to the narrator in [[HumanoidAbomination the form of a beautiful redhead named Triolet]]. The narrator hears part of it, giving him visions of the doomed world where it was crafted, although his friend drags him out of the party before he can hear it all -- and, given that it is indicated to be infectious and capable of rendering a species extinct in only a few generations, this is probably for the best.

[[folder:Fan Works]]
* The capabilities of Sonic's Mystic Melody in ''Fanfic/TheBlueBlurOfTermina'' range from healing the souls of the lamenting dead to outright time manipulation.
* ''Fanfic/TheWizardInTheShadows'' takes a cue from Lúthien, and by extension, the Silmarillion. How? [[spoiler: Eirian]] is of half-maia heritage and uses her magic mostly via singing.
* The music played by Hurdy of ''Fanfic/TheTaintedGrimoire'' can cause a variety of effects. Examples include giving a boost to his allies, curing others of status ailments, and do damage to an opponent.
* In the Franchise/HarryPotter fic ''Hephaestus'' Harry invented a craft called metaldancing, in which a skilled practitioner could shape metal and give it certain properties by singing while manipulating it with their magic.
* In "[[FanFic/TheConversionBureau The Conversion Bureau: Metal Ripper]]" has the PowerMetal musicians cast spells by either shouting out a lyric from their music or by singing.
* ''Fanfic/GameTheoryFanFic'' has magic styles in which the spells are formed with music, and the magitech weapon systems on the Garden of Time are controlled via song.
* Dame Lyra Heartstrings of FanFic/RainbowDoubleDashsLunaverse specializes in spellsongs.
* ''[[Fanfic/TheCadanceverse The Musicians of Ponyville]]'' is an AlternateUniverse story where the Element Bearers are various musicians (Octavia, Vinyl Scratch, Lyra, Bluenote, Medley and Fluttershy) and [[spoiler:the Elements themselves take the form of their preferred instruments, allowing them to defeat the corrupted princesses with a magical concerto]].
* In ''Fanfic/BackgroundPony'', [[color:purple: Luna's]] elegies have powerful magic effects such as instilling paranoia or joy, or causing blindness and freezing cold, and they seem to be the only key to unlocking [[color:green: Lyra's]] curse. Also, the Cosmic Matriarch's song is what created the world in the first place.
* In ''Fanfic/MyLittleBalladeer'' there are two examples:
** This is how the Mane Six summon John to Equestria in the first place, through what is heavily-implied to be the original MyLittlePony theme.
** As a [[WanderingMinstrel Bard]], this is how most of John's magic works.
* In ''Fanfic/MementoVivere'', a VideoGame/FinalFantasyX fanfiction, Rikku's Songstress Dressphere is the definition of this.
* Ironically ''not'' a part of Music/TheBeatles fantasy ''Fanfic/WithStringsAttached''. However, in the sequel, ''Fanfic/TheKeysStandAlone: The Soft World'', John and George encounter a really bad bard with a magic lute that fools everyone except them into thinking he's wonderful. George is so offended that he performs the musical equivalent of a CurbStompBattle by pulling his own (non-magical) guitar from his [[BagOfHolding “closet”]] and proceeding to get much the same reaction from the audience.
* This is Baroness Adagio Dazzle's magical specialty in FanFic/TheRainsverse.

[[folder:Films -- Animation]]
* Music repels the Blue Meanie invasion in ''WesternAnimation/YellowSubmarine''. Especially during ''All You Need is Love'', where the lyrics to the song take physical form as they are being sung.
* Pied Piper is one of the best {{Bounty Hunter}}s in ''WesternAnimation/ShrekForeverAfter''. His flute has a dial that can be set to any known creature and makes them dance uncontrollably when he plays. He is first shown riding on the backs of rats into [[BigBad Rumpelstiltskin's]] palace. He then demonstrates his skill to the witches by making them break-dance. He single-handedly defeats the ogre LaResistance by luring them into a trap and forcing them to dance to "Shake Your Groove Thing". Fiona is not immune, even though she's not a real ogre.
* The Creator/{{Nelvana}} film ''WesternAnimation/RockAndRule'' involves the Music/MickJagger[=/=]Music/DavidBowie-esque villain searching the world for the one voice that can sing a [[http://www.youtube.com/watch?v=1OrKulBelII tune]] to invoke an EldritchAbomination.
* The {{v|ainSorceress}}illainess of ''WesternAnimation/BarbieAndTheDiamondCastle'' uses a flute to work evil magic spells, including mind control and turning people to stone.
* The magic harp uses this to make the giant fall asleep in the "WesternAnimation/{{Mickey|Mouse}} and the Beanstalk" segment of ''Disney/FunAndFancyFree''.
* In ''WesternAnimation/MyLittlePonyEquestriaGirlsRainbowRocks'', the Rainbooms discover playing their music together can turn them into their "pony-like" forms from the previous movie. Furthermore, the villainous trio that is the Dazzlings use their singing voices to [[HatePlague stir up feelings of anger]] [[EmotionEater and feed on them]], with their goal being to use a BattleOfTheBands to gather enough power to TakeOverTheWorld. The climax of the movie involves a quite literal battle between the Rainbooms and the fully powered Dazzlings.
* The eponymous protagonist of ''WesternAnimation/KuboAndTheTwoStrings'' plays a shamisen (a traditional 3-stringed Japanese lute that uses a plectrum) primarily to make paper come to life in the form of living origami, though it can be used to cast other spells as well.
* ''Disney/{{Tangled}}'' has the magic of the flower activated whenever Gothel sings to it. When the magic is transferred to Rapunzel's hair, Rapunzel and Gothel singing the healing verse has the same effect.

[[folder:Films -- Live-Action]]
* Tony from ''Film/EscapeToWitchMountain'' can manipulate objects via telekinesis, but only when he focuses his psychic power by playing a harmonica.
* The Harpists from ''Film/KungFuHustle'' fight using a guzheng, or Chinese Harp. They can manipulate the vibrations into shapes such razor sharp swords capable of cutting through stone. They are homages to "Six-fingered Fiend of the Zither", a famous villain in old Chinese swordplay films.
* ''Film/HocusPocus'':
** Sarah Sanderson sings to get the kids of the town to come to her so she and her sisters can suck the life/youth out of them.
** Winnie also performs a rendition of "I'll Put A Spell On You" at a party where all the adults in town are that enchants them to dance all night (and presumably [[ThereAreNoAdults stop their children from being kidnapped]]).
* In Film/TheThreeStooges short ''Punch Drunks'', Curly is sent into a violent frenzy by "Pop Goes the Weasel".
* ''Film/MastersOfTheUniverse'' has music with the power of opening up pathways between dimensions. The scientist who first discovered this uses a strange-looking instrument that looks roughly like a miniature high-tech pipe organ with crystals in place of the pipes, but a common keyboard synthesizer works just as well when you know the right notes.
* In ''Film/SgtPeppersLonelyHeartsClubBand'' the band instruments kept Heartland U.S.A. a SugarBowl. Once they are stolen the town falls into decay.
* In ''Film/TheGarbagePailKidsMovie'', Captain Manzini eventually tries to get the Garbage Pail Kids back into their garbage pail prison by singing a rhyming incantation. This approach doesn't work, but at the end of the film, he gets the idea to get the Kids into the pail by playing their {{Leitmotif}} backwards. Unfortunately, the Garbage Pail Kids take the opportunity to escape, which results in Manzini getting his behind stuck in the pail.

* ''Literature/InheritanceCycle'': The elves have mastered a form of this that crosses over with GreenThumb: they can cause plants to grow into specific shapes by singing to them in the Ancient Language; it's the reason their cities are mostly made of trees shaped like dwellings. One elf woman in particular, Linnea, was able to merge ''herself'' with the Menoa Tree by singing to it for three days straight, until they became one entity.
* Literally the entire point of ''Literature/SoulSingerOfTyrnos''
* In the ''Literature/{{Spellsinger}}'' series by Alan Dean Foster, the Steve Miller Band's "Fly Like An Eagle" is one of the most powerful magic forces in the universe. It summons the elemental personification of ''the universe itself'', but decreases the lifespan of the universe slightly each time it's used. Generally, the title Spellsingers are mages who work their magic by singing and playing musical instruments. And there is our protagonist, Jon Tom, who is an American student spirited away to this world and who sings rock songs to produce unpredictable results.
* ''Literature/ThePiedPiperOfHamelin''. The Pied Piper used his piping to first lure the rats of Hamelin to their deaths, then later to abduct the children of the town after the people refused to pay him for his services.
* Several characters in Creator/JRRTolkien's [[Literature/TheLordOfTheRings Middle-earth]] stories, including ''Literature/TheSilmarillion'', could achieve magical effects through singing, including Tom Bombadil, Old Man Willow and Lúthien Tinúviel. It helps that Arda, the world of Middle-earth, was literally sung into existence through the Ainulindalë (Music of the Ainur), so anyone with the genealogical and lyrical oomph can do a lot of subtle and overt magic. Finrod the elf sang an illusion into existence, then dueled with Sauron by chanting songs of power. [[spoiler: Finrod lost.]] Lúthien would later also use her music in a duel with Sauron. [[spoiler:She ''won'']].
* And of course Tolkien's inspiration, the sage Väinämöinen of the Finnish national epic ''Literature/TheKalevala''. All magic in the ''Kalevala'' is done through singing. A natural choice, as the entire epic is done in poetic verse designed to be sung, accompanied with playing of a ''kantele'' (a wooden harp).
* Hence, hardly unsurprising that the Lanorei race in [[http://tvtropes.org/pmwiki/pmwiki.php/Literature/Eludoran Eludoran]] could achieve magical effects through singing, as the work in question is an AffectionateParody of Creator/JRRTolkien's [[Literature/TheLordOfTheRings Middle-earth]]. Notable examples include Faolan, who could [[PersonOfMassDestruction shatter mountains with a whisper]]; and Malachi who is reputedly even [[UpToEleven stronger]]. Also, his cousin Lorelei created a physical disguise for her friend by singing an illusion spell, which was apparently so realistic it made their enemy [[HellYesMoment die of fright on the spot]]. It makes [[ItMakesSenseInContext sense in context]] as the Lanorei are a race of [[PettingZooPeople anthropomorphic canines]] (mostly wolves) who have raised song and music into communication and artform.
* Creator/HPLovecraft used this trope in ''The Music of Erich Zann''. Though strange, bizarre or unearthly music often features in his works, this is the only case of the music itself having power.
* In ''Literature/BeingAGreenMother'', the character who becomes Gaea discovers she can control nature with a particular song. (In the next book, ''Literature/ForLoveOfEvil'', another character learns that same song for... ''other'' purposes.)
* ''Literature/TheChroniclesOfNarnia'':
** In TheFilmOfTheBook ''The Lion, the Witch, and the Wardrobe'', Mr. Tumnus literally plays Lucy to sleep with a Narnian lullaby (and a really neat flute); the effects are more psychological and ambiguous in the book.
** [[FanNickname The Emerald Witch]] uses magic music (and fire) to work her MoreThanMindControl in ''The Silver Chair''.
** Aslan creates Narnia with a magic song in ''Literature/TheMagiciansNephew''. This may have been inspired by Middle Earth, as Tolkien and C.S. Lewis were good friends.
* Creator/LEModesittJr wrote a series named ''The Spellsong Cycle'' in which, if you sing it, it happens, but the energy to make it happen comes from your body. Being accompanied by instruments or other spellsingers helps you do more impressive things without passing out due to exhaustion or starving to death. Most people in that book's universe never learn how to sing, because most wizards don't like having potential rivals around.
* In Creator/NeilGaiman's ''Literature/{{Neverwhere}}'', there is a tune which causes anyone who hears it to give money to the person playing it. Of course, they end up nearly ''killing'' the guy, but still... The MagnificentBastard who taught it ''did'' warn that a little went a long way... and picked up a second favor for teaching the street musician the counter ditty.
* In ''Literature/DoraWilkSeries'', the [[FairFolk Elves]] can use music to compel minds to their will. The example shown, an elven boy, uses guitar music to keep people away from him and his sister, but make Dora come to them.
* Creator/PiersAnthony's books:
** ''Literature/ApprenticeAdept'' series, it's made explicit that, although Blue's magic can be invoked simply with rhyme, the spells are dramatically stronger if sung (and stronger still if he uses a musical instrument before reciting his chosen spell).
** His ''Literature/{{Xanth}}'' novels feature triplets named Melody, Harmony and Rhythm, who can "sing and play things real". This can mean anything from turning a girl into a sentient castle to time travel, and they can even identify (though not counter) the magic of the Demons, Xanth's equivalent of gods. Nona, from the Mode series, is fated to overthrow her world's rulers; she can convert others to her cause with a song. Later, she teaches a dragon to stun rats by singing, allowing it to feed on them instead of villagers and completely overhauling a planet's social structure (although Nona didn't come up with the idea). And, as mentioned above, ''Being a Green Mother'' in the ''Incarnations'' series is magic music incarnate.
** ''The Gutbucket Quest'', involved a musician transported to a parallel Earth where music and magic were the same thing. The plot involved going on a quest for a magical electric guitar and invoking the loa of Voodoo with [[ThePowerOfRock the power of Rock and Roll]] to defeat a corporate demon. (Simple, straight-forward storytelling - gotta love it.)
* Rhapsody (the main character of Elizabeth Haydon's ''Literature/SymphonyOfAges'' series) is a Singer, meaning she can use magic channeled through her voice... possibly (the effects of her voice and the definition of "Singer" seem to vary from scene to scene, let alone book to book).
* In the Creator/CordwainerSmith short story ''The Fife of Bodhidharma'', the fife can cause either serenity or madness, depending on how it is played.
* The necromancers' bells in the ''Literature/OldKingdom'' trilogy by Creator/GarthNix can do some dangerous stuff. Different bells give different effects, and the effect also depends on how the bell is played. One of the bells, Astarael, [[BrownNote kills everyone who hears it]]--including the player. More significantly in a setting with functioning necromancy, it sends them "deep into death," killing all but the most powerful victims DeaderThanDead so they cannot return, and at least delaying the return of the rest longer than other methods.
* The Creator/ArthurCClarke story ''The Ultimate Melody'' revolved around a scientist attempting to reproduce the primal tune from which all music is derived. He succeeded, but on hearing the song, [[BrownNote caught it in his head for the rest of his life]], rendering him catatonic. On discovering him, his assistant shut off the machine playing the tune, and it was dismantled before it could be reactivated; the assistant was immune to the effect due to being tone-deaf.
* One of Robert Rankin's novels features Christeen, sister of Christ (written out of Literature/TheBible by the Church), a singer whose voice cures injuries and illness.
* ''Literature/WarForTheOaks'' by Emma Bull ends with [[spoiler:a duel between the lead singer of a rock band and [[TheFairFolk the Queen of the Unseelie Court]] for the fate of the city. By this point, the singer's discovered how to use her music to fuel the "glamour" that faeries can use naturally.]]
* ''Literature/TheWayfarerRedemption'' series by Sara Douglas has magic by music. Its only limitation being that you can't heal anyone unless they're on the brink of death.
* The main character in the ''Bedlam's Bard'' series by Creator/MercedesLackey is a Bard, which in that universe means he is possessed of fairly powerful Magic Music.
* In Lackey's ''Literature/BardicVoices'' series, most of the protagonists have this ability.
* In Mike Carey's ''Literature/FelixCastor'' novels, the main character gets rid of spirits with cantrips played on his tin flute. However, he has to "get the feel" of the ghost first by spending time around it and learning its habits.
* In ''In the Company of Ogres'' by A. Lee Martinez, the fish-like sirens can use a variety of songs to do things, the main one for seducing people, but there are others, including a song rarely used that can destroy almost anything in its way.
* In Creator/TamoraPierce's ''Literature/ProtectorOfTheSmall'' quartet, Numair Salmalin uses a flute tune called the Sorcerer's Dance (stated by WordOfGod to [[ShoutOut refer to]] the Sorcerer's Apprentice music) to move boulders for strengthening a wooden palisade. Although the spell is said to be absurdly simple, Numair jacks it up several orders of magnitude by bringing particularly large boulders from ''ten miles away''.
* Creator/DanAbnett's ''Literature/GauntsGhosts'':
** In the novel ''First & Only'', the Chaos forces they face use drums for summoning.
** In ''Necropolis'', the Chaos forces use chanting to try to corrupt their opponents.
* In Creator/DanAbnett's ''TabletopGame/{{Warhammer 40000}} Literature/HorusHeresy'' novel ''Horus Rising'', Horus's forces come upon a system where xenos transmitters are broadcasting recognizable music.
* In Lloyd Alexander's ''Literature/TheChroniclesOfPrydain'', the bard Fflewddur Fflam carries an enchanted harp. His music is not normally magical, but in the last book, ''The High King'', he uses the harp to keep the party from freezing to death. It starts to play by itself when [[spoiler:he burns it]], giving them the courage to finish the journey. The harp also tends to stretch its strings whenever its owner stretches the truth. As Fflewddur is a born storyteller, many broken strings ensue.
* In Creator/ChinaMieville's ''King Rat'', an evil Pied Piper uses music to wrest control of whole classes of animal, by taking control of those animals' totemic leaders. He also uses music to control humans. [[spoiler: And that's ''before'' he gets the idea of cutting a mix tape, so he can control more than one creature-type at a time...]]
* In ''Lord Fouls Bane'' from the ''Literature/ChroniclesOfThomasCovenant'' the Giant Saltheart Foamfollower uses singing to control the boat he is riding down a river. Lord Mhoram also uses a song to summon the Forestal Caerroil Wildwood.
* Other than just being a exquisitely made instrument, the lowest note on Morgon's harp shatters steel in ''Literature/TheRiddleMasterTrilogy'' by Creator/PatriciaAMcKillip.
* The obscure pulp horror novel ''Deathsong'', by Douglas Borton, is about a Lovecraftian cult that practices music-based black magic. Havoc ensues when they make enemies with a professional singer smart enough to learn songs by ear...
* Being based off a ''TabletopGame/DungeonsAndDragons'' setting, the ''TabletopGame/ForgottenRealms'' novels have a lot of these.
** ''Elfsong'' deals with magic that springs from music, though it's rare and limited to elves (or so we think).
** ''Literature/WarOfTheSpiderQueen'' from the same universe has two:
*** Omraeth, a spellsinger and [[TheEvilGenius Evil Genius]] from Book One.
*** Hallistra Melarn, a major character who carries a lyre and a sword/flute. She uses the lyre to amplify the power of her bae'qeshel songs, which can do anything from heal wounds to weaponized sonic blasts.
* ''Literature/ConanTheBarbarian''
** In Creator/RobertEHoward's story "Literature/RedNails" the enemies get through using piping for a form of magic.
** In ''Literature/TheHourOfTheDragon'' the {{Necromancer}} uses drum magic.
* In the ''Literature/WarsOfLightAndShadow'' series by Creator/JannyWurts, bards are capable of some remarkable feats of magic through their music, be it with an instrument or voice alone. Effects range from manipulating emotions, to activating ancient power sources capable of destroying a city, to redirecting surges through those power sources and restoring natural seasonal patterns, to making half an army stand down. According to hints dropped so far, this is the ''lower'' end of what's possible.
* In ''Literature/AnansiBoys'' by Creator/NeilGaiman, music was used to create the world, and a sufficiently gifted singer can use songs to cause a RealityWarp. (It helps that the characters in question are [[spoiler: the spider-god Anansi and his descendants]].)
* In the shared universe novel ''Exiled: Caln of the Claw'' the Dancers of the Mrem use drums, dance and, in at least one case, bagpipes to strengthen their psychic powers.
* ''Literature/TheDresdenFiles'': In ''Literature/DeadBeat'', we learn that necromancers require a steady rhythm to maintain control of whatever corpses they've raised. Typically, this can be done by beating a drum, or just tapping a book against your thigh. Or you could use [[PostModernMagik a huge sub-woofer mounted on a car]]. Necromancy aside, magic can be powered by emotion, and music can inspire emotion; therefore, music is one of many tools available to magic users.
* In Creator/ShannonHale's ''Book of a Thousand Days'', Dashti uses this to heal various ailments.
* In ''Literature/TheEchoriumSequence'', the Singers of the titular Echorium use five "Songs of Power" to heal, manipulate, punish, or induce living death.
* In Lisa Shearin's "Raine Benares" series, spellsingers are a specialized type of magic user who can channel magic through their voices and cast spells through song. They are particularly effective at influencing emotions.
* In Creator/DianaWynneJones' ''[[Literature/{{Chrestomanci}} The Magicians of Caprona]]'' this is how most spells work. A particularly amusing example occurs when one of the children decide to use the most powerful song spell ever created, used to drive out an evil devil centuries ago, but with the words changed around to clean the dinner dishes. While it did make the dishes look clean, it backfired when for weeks afterward, anything eaten or cooked with those dishes wound up having a greasy, soapy taste. Oops.
** This has interesting consequences for Angelica Petrocchi, who knows dozens of spells by heart [[IneptMage but can't get them to work as intended]] due to her tone-deaf singing. She's somewhat infamous for turning her father green.
* In Creator/RuthFrancesLong's ''Literature/TheTreacheryOfBeautifulThings'', the piper can [[WeatherControl whip up storms]] and [[GreenThumb cause roses to entangle Jack.]]
** Also, the nix is a harpist and lures Jenny with it.
* Terry Brooks's world of ''Literature/{{Shannara}}'' has the ''wishsong'', in which several protagonists, all elven descendents, can create potent melodies of creation and destruction.
* In ''Wody Głębokie Jak Niebo'' some mages write their demon binding spells in the form of songs to make it harder for others to steal their work. Sirocco can control demons through her singing without binding them permanently.
* In ''Literature/RachelGriffin'', the three main protagonists learn music as their branch of magic: [[PrincessClassic Nastasia]] plays [[ElegantClassicalMusician a violin]], Rachel [[MagicalFlautist a flute]], and [[KidHero Sigfried]] [[PersonalityPowers a trumpet]].
* In the ''Literature/{{Lythande}}'' stories, the titular character is a WanderingMinstrel and mercenary mage.
** In the story "Sea Wrack", Lythande is able to enthrall an inn's worth of people with the lute and help heal someone who had been caught by the song of a Siren, unable to think of anything else.
** In the same story, the Siren's song has enough power to cause men to come to it to be eaten, so the fishing village is struggling. The song is powerful enough to even get to Lythande.
* Literature/TheEnchantmentEmporium: Charlie Gale, a member of an entire family of magic users, uses a guitar to help her focus her on-the-spot casting (Rather like Stile in Literature/ApprenticeAdept, above). She can also travel through 'The Wood'[[note]]Essentially an alternate dimension, almost like hyperspace[[/note]], by finding an appropriate shadow or mirror to enter and 'following the song', which can change depending on what she's trying to find; person, place, or [[TimeTravel time to get home without being late for dinner]].
* Tomie dePaola's tale, ''Strega Nona'', involves a cooking pot that can produce unending amounts of cooked pasta when sung to.
* A non-musical poetry variant in Creator/AndreiBelyanin's ''My Wife Is a Witch'' duology. The protagonist, Sergey, is a humble poet, who find out that the HotLibrarian he married is a powerful witch. After she vanishes into the [[MagicalLand dark worlds]], he goes to find her, only to discover that his poetry now works like (sometimes devastating) spells. He later discovers that there is a prophecy about a "witch's husband", since witches never marry, who is supposed to be the most powerful sorcerer who ever lived.
* Central to the ''Literature/ChantersOfTremaris'' trilogy, where virtually all magic is performed through songs, called "chantments".
* Essential to death magic in ''Literature/ShamanBlues''. Necromancers can hear "Earth's song" and raise the dead by singing back, and pretty much entire shamanism revolves around right rythms and songs, used to send ghosts back to the aether, to manipulate them and to call them in.
* ''Literature/TheSagaOfErikTheRed'': To perform her soothsaying ritual, the seeress Thorbjorg requires women who can sing a certain chant called "Varðlokkur" ("Warden-enticers"; a 'warden' is a guardian spirit). Gudrid is the only one present who can sing the song, and she does so. Thorbjorg is very pleased and says that the song has attracted many spirits, because Gudrid has sung so beautifully, and it are the spirits who supposedly reveal the future to Thorbjorg.

[[folder:Live-Action TV]]
* A sketch from British TV comedy series ''Series/ThatMitchellAndWebbLook'' had a man being given a green clarinet which, when played at someone, caused them to dance and sing an embarrassing truth about themselves. He used it to live a life of luxury, until another person was given a red tuba which caused... well, [[BrownNote an unfortunate comeuppance]].
* In an old ''Series/TheKidsInTheHall'' sketch, Satan is driven back into Hell by the "Holy Trinity" of guitar chords (E-A-B, or the opening chords of ''Smoke on the Water'').
* The series ''Series/{{Threshold}}'' involved an alien audio signal that was able to ''alter the genetics'' of [[BrownNote anyone who happened to listen to it]].
* ''Series/TheOuterLimits1995'': In "Music of the Spheres", the titular music is a signal from space which, in addition to being extremely addictive, ends up causing a series of dramatic physical transformations in listeners. Notably, unlike most {{Brown Note}}s, [[spoiler: the changes the music causes ultimately turn out to be beneficial.]]
* ''Franchise/SuperSentai'' / ''Franchise/PowerRangers'' occasionally summon their HumongousMecha with music. The Green Ranger from ''Series/MightyMorphinPowerRangers'' had a dagger that doubled as a flute, and ''Series/PowerRangersNinjaStorm'''s Samurai Ranger had a guitar that could be used to bring in a mammoth zord.
** A couple [[MonsterOfTheWeek Monsters Of The Week]] used music too, such as the Gnarly Gnome and Guitardo. (There was an ironic twist with the first one; he used his music to hypnotize some teenagers, hoping to lure the Rangers into an ambush, but the plan had a FatalFlaw that he didn't count on: one member of the group he targeted was hearing impared, managed to escape, and warn them, ruining any chance of a surpise attack.)
* In the premiere of the BBC series ''Series/{{Merlin 2008}}'' a witch, magically disguised as a famous singer sings a song that causes the entire court of Camelot to fall into an enchanted slumber so she can assassinate Arthur. Luckily Merlin instinctively recognises the magic and covers his ears in time.
* ''Franchise/KamenRider'':
** Most seasons only use music as incidental sound effects during transformations or special attacks, but ''Series/KamenRiderKiva'' has a violin-playing protagonist, and one episode had him playing the mystically-created violin built by his father to force himself into shapeshifting. His sentient TransformationTrinket, Kivat, uses whistles to summon weapons, call Castle Doran, or even start Kiva's Rider Kick.
** Then there's ''Series/KamenRiderHibiki'', where the enemies can only be fought using "pure sound". The {{Transformation Trinket}}s are weaponized instruments, as well, and each Rider carries a set of Disc Animals, which when not in use fold up into compact discs.
** [[Series/KamenRiderExAid Kamen Rider Brave]] uses the ''[=DoReMiFa=] Beat'' [[TransformationTrinket Gashat]], based on rhythm-dance games, letting him use a chiptune version of the show's theme song as a weapon.
* ''Series/BuffyTheVampireSlayer'', with the episode "Once More with Feeling". A musical demon causes life in the entire town to be a musical. Doesn't seem too bad, until it's revealed you uncontrollably spill your deepest secrets in songs sooner or later. And sooner or later, you will dance and sing yourself into a fiery death (the demon is stopped before more than a handful of Sunnydalians burn). Relatedly, the demon claims to have given a certain Roman emperor "his very first fiddle," thus also dovetailing with the trope.
* ''Series/{{Angel}}'' has a bit of a variation: Lorne's singing abilities (great though they are) don't confer any magical effects, but when he hears ''other'' people sing, than he is able to read their destinies. Well, he is able to sing high enough to cause physical pain to people and incapacitate them. And even ordinary singing is too much for most inhabitants of his dimension.
* ''Series/Warehouse13'':
** Used in when a group of bank robbers commit crimes by playing a specific song that sends the listener into blissed-out ecstasy, then taking the money while they're incapacitated.
** Later cropping up again several times in the show's final season. First, Frances Farmer's Music Box. Sends its winder into easily provoked, telekinetically powered outbursts of pure rage.
** Then there was Oliver Sacks' Record Player, which puts listeners into comas as long as it's playing, comas so deep muscles and organs atrophy and fail within hours.
** Finally, Chuck Yeager's Favorite LP. Combined with the above Record Player, produces sonic booms strong enough to throw a person backwards if anyone tries to turn it off.
* [[spoiler:Emma]] from ''Series/{{Heroes}}'' has this power; so far we've seen her use her cello to [[spoiler:summon people she is thinking about and make a crack in her apartment wall]].
* The MonsterOfTheWeek in the ''Series/{{Haven}}'' episode "Harmony" can temporarily cure and cause mental illness by playing music.
* While there are several other aspects to the show, this is the entire premise around the titular characters in the Japanese drama ''Series/DaimajinKanon''. The song that was passed down to Kanon from her grandmother is actually a spell that awakens the giant magical evil-fighting statue, Daimajin, from its slumber to save humanity from a demonic invasion. It only works when it's sung "with all of one's heart".
* ''Series/DoctorWho''. In "A Christmas Carol" a woman's singing calms the storm around a planet, as well as its flying fish. When the Doctor tries coming up with a TechnoBabble explanation, [[MeasuringTheMarigolds the fish bite him in irritation]].

* "The Bells Are Ringing" by Music/TheyMightBeGiants.
* "The Walls Came Down" by The Call.
* "Make You Sin" by Music/{{Angelspit}}
* "The Lyre of Orpheus" by Nick Cave and the Bad Seeds
-->''Look what I've made, cried Orpheus\\
And he plucked a gentle note\\
Eurydice's eyes popped from their sockets\\
And her tongue burst through her throat''
* "[[Music/SuperTrouper The Piper]]" by Music/{{ABBA}}.
* "The Heat of the Blood" by Music/TomSmith; a [[LetsDuet duet]] where his song is an attempt at magic seduction, and hers is an attempt to fight it off.

[[folder:Myths & Religion]]
* In Literature/TheBible, the walls of Jericho fall after the Israelites spend seven days marching around the city, blasting trumpets and shouting in turn. Hebrews 11:30 attributes this to faith in God rather than any magical power the army's music had, however.
* Not just Literature/TheKalevala, traditional Finnish magic in general consisted of spellsongs that were either sung or chanted, depending on the context. This makes sense, because most spells were essentially short stories relating the [[IKnowYourTrueName mythological origin]] of things like fire, iron, living things and such, because knowing the primordial nature of a thing was thought to [[FunctionalMagic give power over it]]. As such, spells were passed down by teaching them as songs, often as part of larger epics or stories, with the poetic meter ensuring the fidelity of the oral transmission. Notably, sages also apparently engaged in [[WizardDuel contests of magical knowledge]] which were conducted by singing as many spells as they could remember; many thousands were recorded in the 19th and early 20th century.
* Similarly, the Ancient Greeks actually believed music was magical. They had a single word that meant both "to sing a song" and "to cast a spell." This is most obvious in the story of Orpheus, mentioned above. It also shows up in the teachings of Greek philosophers - Plato's writings appear to be in a 12-note chromatic scale, and most famously Pythagoras first realized he could predict things using math (physics, basically) by observing the strings of his lyre, and went on to incorporate divine music into his belief system.
** This then carried over to the Latin language: the verb "incantare", meaning "to cast a spell", derived from "cantare", "to sing". Both have descendants in modern Romance languages and even in English: that's where "enchant" and "chant" come from.
* [[Myth/GreekMythology Orpheus]], who sang so well he (almost) restored his wife to life. And made the Furies weep. And made trees pick up their roots and rocks roll over to him just so they could listen.
-->''Orpheus, with his lute, made trees and the mountain tops that freeze, Bow themselves when he did sing: To his music, plants and flowers Ever sprung; as sun and showers There had made a lasting spring. Ev’ry thing that heard him play, E’vn the billows of the sea, Hung their heads and then lay by...''
* The Sirens of Greek mythology were creatures with hypnotic singing voices; their singing enchanted sailors to crash to their deaths on the rocks. Orpheus was able to counteract them with his lute in the myth that inspired ''Film/JasonAndTheArgonauts''. Over the years, this has caused myths to bleed together and people to associate this trait with mermaids instead - to the point that we now have a [[SirensAreMermaids trope for it]].
* The [[https://en.wikipedia.org/wiki/Neck_(water_spirit) Neck]] in Scandinavian mythology is a shapeshifting creature that plays enchanting music.
* The [[Myth/CelticMythology Irish legend]] of the harp of Daghda, which could cause pain, laughter, or peace through music.
** The Irish ''filidh'' could also do that. Accordingly they were held on the same level as the kings of Ireland, since they could destroy their reputation (and potentially ''maim'' them) with a song.
* In the Swedish legend of the Hårgadance a mysterious fiddler turned up one day in the village of Hårga during a celebration and started playing a song on his violin that made everyone dance enthusiastically. Too late, the people realized that the man, who they now saw had a goat's leg, was the Devil himself. They were unable to stop dancing, and kept doing so while the fiddler led them up the nearby Hårgamountain. There, he kept playing until everyone had been killed and their bodies torn to bits by the intense dancing. The top of Hårgamountain is still flat to this day because of the wild dance.
* In "Literature/TheLoreley" by Heinrich Heine, the fairy lady Loreley lures skippers on the Rhine to their doom by the power of her song.

[[folder:Pro Wrestling]]
* Wrestling/MattHardy summons his brother [[Wrestling/JeffHardy Jeff]] with "[[MakesJustAsMuchSenseInContext this lovely violin]]" so he can defeat him in [[Wrestling/{{TNA}} The Final Deletion]].

* D.B. Humphries' ''Dragon Song'', Rina used a form of song magic as a method of conceiving children.

[[folder:Tabletop Games]]
* Bard classes are also popular here, based on the original ''TabletopGame/DungeonsAndDragons'' bard.
** In 3rd Edition ''D&D'', Bards can not only play magical music, but can also cast spells -- but unlike any other class, every spell they cast has a vocal component, and also unlike any other class, they cannot cast silent spells as a bard even if they would have the ability to do so otherwise. It does not ''strictly'' have to be music, but magical recitation (Perform (Oratory), Perform (Comedy) and Perform (Acting) all qualifies the bard to use their abilities) is close enough.
** The 2nd Edition {{sourcebook}} ''Player's Option: Spells and Magic'' introduces the Song Mage, who faces the same restrictions.
** Supplemental 3rd Edition material results in new ways to "spend" bardic songs, alternate bardic music to learn, ways to further combine music and magic, prestige classes like the Virtuoso and Lyric Thaumaturge, new instrument types, and bayonets to suit lutes, flutes, and fiddles of every size.
** The 3rd Ed Dungeon Master's Guide features a number of magical music instruments, such as bells, lyres, drums, flutes, and pipes that have helpful or harmful effects. Satyrs' pipes are especially fun.
** Any monster with a hypnotic song, like harpies or cloakers.
** The alternate magic system ''TabletopGame/SpheresOfPower'' has the Skilled Casting drawback, which has you use a Perform, Profession or Craft check to use your magic, so you can [[RuleOfFunny literally walk on walls by singing]] ''[[Creator/LionelRichie Dancin' on the Ceiling]]''.
* In ''TabletopGame/InNomine'' reality is controlled by something called "the Symphony;" the setting's "magic" consists of manipulating the Symphony in a couple of different ways. The most direct, used by angels and demons (and some special humans) are Songs, which are basically specific melodies which (when coupled with Essence expenditure) produce all sorts of special effects from healing to blowing stuff up. The less experienced have to actually vocalize the Song (and perform specific movements/gestures), while the more skilled can just invoke them mentally. The use of Songs creates "disturbances" in the Symphony which can be tracked down to their source (both the place and the person) by anyone with supernatural abilities who is close enough and perceptive enough to "hear" them.
* The premise of ''Jazz Voodoo'' from ''[[http://www.beyondthestorm.us/ Beyond the Storm: Shadows of the Big Easy]]''.
* In ''TabletopGame/{{Shadowrun}}''/''Earthdawn'', Thayla's singing was so beautiful it could keep the Horrors at bay.
* In ''TabletopGame/ArsMagica'' the Enchanting Music ability fits the mold as do the "Holy Music" (Holy) Method and the magic of the Hyperborean Hymnists. Certain applications of Performance Magic and the Enchantment (Faerie) Method also work.
* Pavane of Slaanesh ability (and its big brother, the Grand Pavane) of Chaos Daemons in ''TabletopGame/{{Warhammer 40000}}'' is described as magic music that forces those who hear it start dancing and fall under the daemon's control.
* ''TabletopGame/SirenTheDrowning'' has the Sirens' equivalent of magic, Verses, work on this concept. The Verse is composed with three different parts, all required to have it function. The Introduction describes what or who the Siren is targeting with the Verse and it's duration, the Opus is what she's using to affect the target or affecting within the target, and the Conclusion dictates how much she can wield the Opuses. It should be noted that a Siren may need to use a Performance to help the Verse, but if she tries without one then she may find her Verse significantly depowered.
* This is the Argent Adept's ''thing'' in ''TabletopGame/SentinelsOfTheMultiverse''. Mechanically, he uses both Equipment (his instruments) and Ongoings (his songs); by activating an instrument's power, he can trigger the effects of the songs, which are divided into Rhythm, Harmony and Melody, with Rhythm and Harmony additionally having both Perform and Accompany effects that are activated separately. It's all rather complicated, so he's a lot easier to run in the digital version, but the results speak for themselves: while the Adept's setup time rivals that of the Great Wall of China, he can get some truly ridiculous power loops when he gets going, distributing heals, buffs, cards, plays and power uses to allies. He does have some damaging effects; he just rarely uses them, because who needs to inflict small amounts of ice, fire or sonic damage when you could massively buff your teammates, who are better at that?

* Many, many witches, wizards, sorcerers, and sorceresses sing incantations.
* Tamino's flute and Papageno's glockenspiel in Mozart's ''Theatre/TheMagicFlute''. The Queen of the Night casts spells, arguably, with her dazzling coloratura passages.
* In ''Theatre/{{Wicked}}'', Elphaba sings "Eleka Namen Atum Atum Eleka Namen; Eleka Namen Atum Atum Eleka Namen," and then proceeds to lampshade this with "What good is this chanting? I don't even know what I'm reading!"
* ''Theatre/PeerGynt'': Solveig defeats [[EldritchAbomination The Boyg]] by singing hymns.

[[folder:Video Games]]
* {{MMORPG}}s often feature some sort of game mechanic or class that utilize songs with some kind of power:
** ''VideoGame/RagnarokOnline'' features the Bard and Dancer, both of whom can use a plethora of magically musical skills to aid their allies and hinder their enemies.
** In the original, scrapped version of ''[[VideoGames/TabulaRasa Richard Garriott's Tabula Rasa]]'' dating from 2004, the DamageTyping system involved a wholly unique of weapons for each damage type. Spirit weapons involved dancing and music--one featured weapon, for example, rotated like a hula-hoop when not in use and transformed into a harp when attacking.
** In ''VideoGame/KingdomOfLoathing'', the Accordion Thief can play various songs that will provide buffs to themselves or other players--for example, "Ode to Booze" increases the adventures you get from drinking alcoholic beverages, "Fat Leon's Phat Loot Lyric" boosts item drops, and "Polka of Plenty" increases Meat drops.
** ''Tiara Concerto'' takes place in a WorldInTheSky where all magic is based around this principle.
* There is a story arc in ''VideoGame/CityOfHeroes'' that involves recovering "The Dirge of Chaos" before it can be broadcast over [[CityOfAdventure Paragon City's]] airwaves.
* Most spells in ''Franchise/TheLegendOfZelda'' series require Link to use an instrument and a certain tune to cast them. This tradition was started in the [[VideoGame/TheLegendOfZelda original game]]. It had a flute with certain magical effects.
** Very Prominently used in ''Ocarina of Time'' (of course), ''[[VideoGame/TheLegendOfZeldaMajorasMask Majora's Mask]]'', and ''[[VideoGame/TheLegendOfZeldaTheWindWaker The Wind Waker]]'', with several varieties of magical effects available through music, but nearly every game has at least one example of Magic Music, most often as the WarpWhistle.
** Taken to the fullest extent of the trope in ''[[VideoGame/TheLegendOfZeldaLinksAwakening Link's Awakening]]'', where the [[PlotCoupon 8 Instruments of the Sirens]] were required to wake the Wind Fish and leave the island, in addition to having an ocarina which had 3 plot device songs.
** While ''[[VideoGame/TheLegendOfZeldaTwilightPrincess Twilight Princess]]'' doesn't have an ''instrument'' per se, Link can blow (or howl in wolf form) on grass whistles to summon Epona or birds, and late in the game gets a whistle that can also call Epona. And in his wolf form, Link can also howl at Howling Stones to summon the Golden Wolf/Hero's Spirit and learn new moves from him.
** It was obvious that ''[[VideoGame/TheLegendOfZeldaSpiritTracks Spirit Tracks]]'' would go with this Trope ever since it was revealed that the game's Japanese name was "Earth's Whistle". The "whistle" was revealed to be the Pan-flute like "Spirit Pipes", which are played by using the touchscreen and microphone in tandem. They work almost identically to magic instruments from earlier games. You also play duets with the Lokomo and Zelda with instruments such as bass, shamisen, flute, drums, and oboe, and to some extent... a pair of vocal cords. Which are held by Gage, Steem, Carben, Embrose, Rael and Zelda respectively.
** ''[[VideoGame/TheLegendOfZeldaSkywardSword Skyward Sword]]'' has the harp, which is stated from the very beginning to have been passed down by the goddess. [[FairyCompanion Fi]] also dances along to the songs that Link plays. ''[[VideoGame/TheLegendOfZeldaOracleGames Oracle of Ages]]'' also has a harp, which is used to travel through time.
*** Notably the Goddess harp is the same harp Sheik uses in Ocarina of Time to teach Link that game's magic music, having been held onto by held onto by the Royal Family of Hyrule after it's founded by Skyward Sword Zelda or some descendant. Sheik uses the harp as weapon in Hyrule Warriors as well, and Zelda is shown holding it in the first cut scene of that game.
* Elena in ''VideoGame/GrandiaII'' sings a song that seemingly lifts the spirits of everyone in the world, brings Ryudo back from oblivion, and gives the heroes the power to defeat a dark god.
* ''Franchise/{{Pokemon}}'' just loves to abuse this trope. The Pokéflute/Pokémon Whistle can magically wake Pokémon up. In ''VideoGame/PokemonGoldAndSilver'', in lieu of a Pokéflute, you can tune to a certain radio station to wake your Pokémon up. Another radio station, depending on the time of day, an increase or decrease encounter rates with the Pokémon March and Pokémon Lullaby respectively. In ''Diamond'' and ''Pearl'', the event item Azure Flute is used to awaken Arceus. In fact, a good number of the [[http://bulbapedia.bulbagarden.net/wiki/Category:Sound-based_moves sound-based moves]] in the game are musical.
* ''VideoGame/{{Rime}}'': The main character activates all manner of items in his environment by singing or shouting at them
* ''VideoGame/WarioLand3'' has several treasures that release off-key, broken, strange melodies that unlock events in other stages. These short melodies come together during the credits music and create ''[[http://www.youtube.com/watch?v=AH70CwY__Ms&feature=player_detailpage the best fucking song ever composed]]''.
* The 5 Instruments of the bard from ''VideoGame/RomancingSaGa2'' they are required to meet with the Iris race.
* ''VideoGame/TalesOfTheAbyss''
** Mystearica "Tear" Grants uses this in six of her spells, the pieces of Yulia's Grand Fonic Hymn. It in and of itself is not used in combat, nor is the Seventh Hymn. They do provide {{Cutscene Power|ToTheMax}} in the fight with [[spoiler:Van]] though.
** Some magic is sound based in this game, namely the Seventh Fonon, the Fonon of Sound. Unlike the six other Fonons which are based on your typical ElementalMagic, the Seventh Fonon was created as a mutation of the other six in the Planet Storm combined with memory particles. The Seventh Fonon can be used for reading the Score, HealingHands, Daathic Artes, and, you guessed it, Fonic Hymns.
** It's noted that most fonic hymns are actually ''weaker'' than other fonic artes. Yulia's Hymns are a sole exception as they are actually stronger than normal fonic artes. This is because the Grand Fonic Hymn is the "proof of pact" between Yulia and Lorelei.
* An ocarina and its music were also the source of your power in the ''VideoGame/JadeCocoon'' games.
* In ''VideoGame/LaMulana'', an ocarina is required to speak with the Sages.
* The eponymous Bard from ''VideoGame/TheBardsTale'' is able to summon up to four magical creatures and/or people at a time with the music he learns (and can play on a variety of instruments, including a lute, a flute, and [[InstrumentalWeapon the Shadow]] [[https://www.youtube.com/watch?v=_jmoNao90kI Axe]]). Also, if you can find the [[TalkingWeapon Ego Sword]], [[https://www.youtube.com/watch?v=s7o-Hfs2a20 it can sing to summon them as well.]]
* The AdventureGame ''VideoGame/{{Loom}}'' is all about this; Weavers can hear the supernatural sounds of the world around them and then play them on their distaffs to produce supernatural effects.
* ''Franchise/FireEmblem:''
** In ''[[VideoGame/FireEmblemElibe the Elibe games]], while Ninian and Lalum invoke {{Magic Dance}}s, the bards Nils and Elphin prefer to use this to restore movement to ally units.
** The herons' ''galdrar'' in ''[[VideoGame/FireEmblemTellius Path of Radiance]]'' and ''[[VideoGame/FireEmblemTellius Radiant Dawn]]'' have similar effects, but depending on the song, they might do more... [[spoiler: like [[http://fireemblem.wikia.com/wiki/Galdr_of_Rebirth restoring damaged souls back to normal and reviving the Serents Forest]].]]
** In ''VideoGame/FireEmblemFates'', the Songstress Azura uses her songs and [[MakingASplash water powers]] to help her companions.
* ''Franchise/FinalFantasy'':
** The recurring summon Siren inflicts non-elemental damage and the Silence status effect by playing music off her harp.
** [[QuirkyBard Edward]] in ''VideoGame/FinalFantasyIV'' can inflict damage on enemies, as well as confuse them and put them to sleep, with his harp-playing. He can't be considered a terrible musician; just one that knows his audience, given in the DS remake he can learn Life's Anthem, which rapidly restores the HP of the party as long as he isn't interrupted. And then there's the songs available to the Bardsong Augment...
** Speaking of Edward, another song used in the game, though not in combat, is one he learned to dispel evil spirits. Coupled with Whisperweed, this is how he [[spoiler:cripples the Dark Elf's magnetic powers]].
** Hurdy in ''VideoGame/FinalFantasyTacticsA2'' is pretty much the moogle version of Edward, including the ability to hide. His abilities are a mixed bag, the best being a song that restores MP. [[GuideDangIt Learning that song is another matter...]]. Fortunately, he can learn other jobs like everyone else.
** Edwards revamped abilities are likely inspired by the Bard class of ''VideoGame/FinalFantasyV'', which could use several useful songs, for instance to speed up the other party members, restoring mana over time or dealing heavy damage to undead enemies.
** The Bard class has existed for a while in ''Final Fantasy'', including ''VideoGame/FinalFantasyIII'' and ''VideoGame/FinalFantasyTactics''; in fact, Hurdy's ability list, other than Hide, is taken practically verbatim from ''Final Fantasy Tactics''.
** ''VideoGame/FinalFantasyX2'' has the Songstress class, which is a pop star combination of the standard bard and dancer. It combines magic music to buff the party and [[MagicDance magical dances]] to screw with the enemy.
** As mentioned in the brief blurb regarding MMORPGS above, ''VideoGame/FinalFantasyXI'' has had the Bard class since its initial release. The most powerful support class in the game; it applies anywhere from 1 to 4 magical music songs, depending on instrument used, to allies giving almost any conceivable buff, and can also apply many powerful debuffs to foes. A skilled Bard can even keep a different set of songs active on melee and ranged players.
** ''VideoGame/FinalFantasyXIV'' brought back the Bard class, although they are primarily bowmen they still have several songs for various purposes such as RegeneratingMana, a DamageIncreasingDebuff, a ChargedAttack song, a movement buff and shield from debuffs.
* ''VideoGame/BravelyDefault'' has Praline (full name/title Praline a la Mode, Diva of the Battlefield), holder of the Performer [[PowersAsPrograms asterisk]], who uses her singing to [[StatusBuff buff]] her allies' stats. You can do it too once you defeat her [[PowerCopying and gain the Performer job]].
* The magic system in ''VideoGame/BrutalLegend'' is based around playing HeavyMetal solos on an enchanted electric guitar. In fact, ''everything'' in the game world runs on heavy metal, not just magic.
* ''VideoGame/ExaPico'':
** [[OneGenderRace The all-female race of Reyvateils]] was created with the ability to create various magical effects through their songs. This includes things like healing, creating elemental bursts, summoning beings to attack, or even (on the upper scale of things) creating entire continents. Songs can sometimes be in upwards of 6 minutes in song length, and can either be sung solo or in combination with other Reyvateils. What makes this particularly interesting is that a single song can have multiple voices in it at any given time, but it is still being sung by one individual capable of singing in multiple voices at once. [[https://www.youtube.com/watch?v=nFdRhJpUKt0]]. Additionally, most of the music has very computer-style names usually including EXEC or some variation. The implication of many of these is that the music is similar to some kind of computer executable that is executed by the goddess of the land.
** [[ConLang "Magical languages"]] (Hymmnos, Pastalia, Risshizentsukyomi and Ar Ciela) are used to create the really earth-shattering effects.
** Note that the entire setting of the franchise depends on song magic. Airships run on ''symphonic power'', item crafting is due to applied "Wave Theory" (yes, [[MinovskyPhysics fictional physics]]), the initial singularity ''[[RealityWarper sung the universe]]''...
* In ''VideoGame/KingdomHearts'', [[ThatOneBoss Demyx]] (the Melodious Nocturne of Organization XIII) uses a blue sitar that's bigger than he is to summon water-clones. It also makes for a ''really'' effective club.
** There is also the Symphony Master from "VideoGame/KingdomHeartsBirthBySleep" , that attacks by summoning a trumpet, a drum, and a violin and near blows Terra to Kingdom Come before the fight.
* Luna from ''VideoGame/LunarTheSilverStar'' has special moves that all revolve around her singing ability.
* ''VideoGame/EarthBound'':
** The Eight Melodies (Queen Mary's Song) from ''VideoGame/EarthBoundBeginnings'' is an interesting example of this trope. While you learn each melody from some really interesting places (including a singing cactus), the song itself is not magical. The real power of the song comes from the memories associated with it, which is why it only has an effect on [[spoiler:Queen Mary and Gigyas]].
** The Sound Stone in ''Mother 2/Earthbound''.
* This trope is the central mechanic of ''VideoGame/RhapsodyAMusicalAdventure''. The heroine Cornet controls her puppet army by playing her magical trumpet.
* The girl in ''[[VideoGame/AstekaIITemploDelSol Tombs & Treasure]]'' for the NES could create various magical effects, primarily directing the sun's rays and turning [[TakenForGranite flesh to stone]], by playing a set of golden panpipes.
* The moodhorn in ''VideoGame/TheSpellcastingSeries'', which can [[ExactlyWhatItSaysOnTheTin alter people's moods in a number of ways]]. Only one song is required for one puzzle, [[DevelopersForesight but almost every character in the game has scripted responses]] for each song in the book.
* ''VideoGame/LegendOfMana'' lets you cast spells using magical instruments. Each instrument has its own spell, and you gain stronger ones through ItemCrafting using elemental coins and a variety of materials.
* In ''VideoGame/InfiniteUndiscovery'', Capell obtains a flute from a claridian named Saruleus, which allows him to play music that can dispel illusions among other effects. It's just a pity that the one song that really counts, the one that stops them from hitting the Lunar induced BerserkButton, turns out to be pretty ineffective unless played constantly, which is impractical.
* Ricardo from ''VideoGame/ShadowHearts: From the New World'' can play songs with his guitar for various effects, from casting positive status effects on the party, sans himself. More songs can be composed when Ricardo find new items as his inspiration.
* In ''VideoGame/{{Aquaria}}'', the protagonist Naija sings songs to change her form or to cast a spell, while a nine-note motif, foreshadowed in the soundtrack, turns out to be an important part of TheReveal.
* A mermaid song is used to rid a town of monsters in ''VideoGame/ChronoCross''. And then of course, there's [[spoiler: the song that defeats the final boss and gets you the GoldenEnding]].
* In ''VideoGame/{{Mabinogi}}'', ranking musical skills high enough gives characters the ability to play music that can buff teammates, debuff mobs, and even [[MindManipulation mind-control]] single enemies.
* ''VideoGame/{{Touhou}}'':
** Mystia's singing can cause night-blindness.
** The Prismriver Sisters, a trio of musical poltergeists who use their instruments for BulletHell, is also said to have an emotional impact on the listener: Merlin's makes you peppy, Lunasa's makes you depressed, and Lyrica's deadens your feelings altogether.
* Sona from ''VideoGame/LeagueOfLegends'' uses this for all of her abilites, with a touch of MusicalAssassin.
* The Bard class from ''VideoGame/EdenEternal'' uses their music to attack and buff themselves and their teammates, playing either a lilting melody or a [[RuleOfCool death metal ballad]].
* ''VideoGame/DigitalDevilSaga'' has Sera's music, which can calm down victims of the HorrorHunger... but it has its limits.
* ''VideoGame/SuperRobotWarsAlpha 3'', ''VideoGame/SuperRobotWarsDestiny'' and ''VideoGame/{{Super Robot Wars Z}}2: Saisei-Hen'' have Basara from ''Anime/{{Macross 7}}''. The [[http://www.youtube.com/watch?v=awAi36JjFiQ following songs]] in ''Z2: Saisei-Hen'' give the corresponding [[StatusBuff buffs]] to his allies:
** Planet Dance: Heals HP
** Totsugeki Love Heart: Raises Morale
** My Friends: Heals SP
** Try Again: Raises Stats
** Dynamite Explosion: Gives Spirit Commands (Fortune, Effort, Accelerate, Flash)
* In ''VideoGame/{{Ys}} I'', one purple-clad area of Darm Tower has creepy music that hurts you until you smash the pillar where it is coming from.
* [[MusicForCourage Maybe it]] [[ClapYourHandsIfYouBelieve isn't magic]], but the Soldier's Buff Banner, Battalion's Backup, and Concheror from ''VideoGame/TeamFortress2'' has got to count for something. After all, ordinary music doesn't normally give you and your teammates [[CriticalHit mini-crits]] in attacking, [[StatusBuff reduced damage]] from enemy attacks, or [[LifeDrain healing from the damage you and your teammates deal]]. There's also the Medic's Amputator, which can heal his teammates when he taunts with it (read: playing it like a violin).
* The Hunting Horn weapon in the ''VideoGame/MonsterHunter'' series can bestow its player and their allies with a huge variety of different beneficial effects that emulate those of various items and equipment skills, such as healing, status ailment removal, and immunity to monster roars. Each horn has a limited selection of songs it can play for the sake of keeping it balanced, though.
** The Qurupeco is able to produce similar benefits for itself and other monsters in its vicinity by singing. However, hitting its throat sac before it finishes a song can cause it to mess up and heal/buff you, instead.
* Most of the combat system in ''VideoGame/DoubleDragon Neon'' revolves around collecting mixtapes to gain statboosts and new abilities and attacks, and using the Tapesmith to make them stronger via mythril.
* ''[[VideoGame/MarioAndLuigiDreamTeam Mario and Luigi Dream Team]]'' has the Dreambeats, which cause any ordinary person who hears them to immediately fall asleep. Antasma and Bowser use their power to knock out the population of Pi'illo Isle and use their dream energy to power the Dream Stone.
* The Mariachi Guys in ''VideoGame/PaperMarioStickerStar'' are able to provide enemies with a variety of stat boosts using their guitar tunes. While they never attempt to engage Mario in combat on their own, they'll FlashStep over to him and join in on any battles that are started within earshot of their music. Made more annoying by the fact that they'll run away if they're the only enemy left in battle, plus they're usually hiding in the field, which can make getting rid of them for good rather difficult.
* Crops up at several points in ''VideoGame/TheSecretWorld.'' The siren song near the beginning is produced by some artifact that keeps the Fog away. Later, in Egypt, [[spoiler: the song of the Sentinels keeps the Black Pharaoh sealed inside his pyramid]]. Later still, you find out that [[spoiler: the Gaia engines that you encounter towards the end of the New England and Transylvania main stories act as music boxes to keep [[EldritchAbomination the Dreamers]] asleep]].
* Joelle from ''VideoGame/EternalEden'' uses music-based skills, which affects the entire party. Her songs can heal and buff up allies, while debuffs, or put status effects on, enemies.
* This is Jimmy's speciality in ''VideoGame/SouthParkTheStickOfTruth''. It replenishes power-points, applies buffs and debuffs, puts enemies to sleep, and makes them shit blood.
* ''[[Series/ShiningSeries Shining Resonance]]'' features this in spades - it goes so far that most if not all party members actually fight with weapons that ''double as musical instruments'' that are used to play "legendary scores" left behind by ancient dragons... or something.
* In ''VideoGame/Drakengard3'' the power of the Intoners is based around songs. If they enter [[SuperMode Intoner Mode]] they begin singing along with the backround music and become ridiculously strong. They can also use their singing to help their disciple [[SummonMagic summon giant magical creatures]] [[spoiler: without paying a price]]. If they are sufficently strong they can summon them by themselves. [[spoiler: However their songs seem to have unintentional [[BrownNote side]] [[BodyHorror effects]].]]
** Note that under most circumstances, calling some of the noises they make "singing" would be a stretch. Zero begins with a berserk scream of bloodlust, Three with a blood-curdling shriek, and Five sounds like [[DoesThisRemindYouOfAnything she's enjoying herself way too much]].
* Both non-numbered installments of the [[VideoGame/RuneFactory Rune Factory]] series involves Spirit Songs.
** In [[VideoGame/RuneFactoryFrontier Frontier]] you can ask Candy to sing in order to manipulate the weather or create Rune Stones in exchange of some Runeys. [[spoiler: In fact, Spirit Song was the reason Whale Island was able to stay in the sky.]]
** [[VideoGame/RuneFactoryOceans Tides of Destiny]] has Odette singing it to communicate with the Arch Dragon. [[spoiler: It was used by the BigBad to control shrine bosses and Dark Spirits, and later on, the protagonist has Odette and her sisters sing a variation of it in order to summon someone from the past.]]
* In the NES version of ''Film/{{Willow}}'', the Magic Ocarina summons the dragon Po.
* In ''Franchise/TheElderScrolls'', the extinct [[OurDwarvesAreDifferent Dwemer]] practiced a form of this. They were a race of extreme {{Naytheist}}s who created advanced {{Magitek}} SteamPunk technology. They were also known to [[LoopholeAbuse bend the "Earth Bones"]], essentially the laws of nature and physics in the mortal world. They accomplished this by altering the "tonal architecture," or the sounds and vibrations, of the Earth Bones, which allowed them to [[RealityWarper hijack the fundamental laws of the world and used them for their own ends]]. After discovering and attempting to tap into the power of [[CosmicKeystone the heart]] of a [[GodIsDead "dead" god]], they did ''[[RiddleForTheAges something]]'' which caused their entire race to disappear from all known planes of existence in a single instant, leading to their presumed extinction.
* ''VideoGame/RuneScape'' has the elven crystal-singers, who shape and empower divine crystals for specific effects with music. The player learns a little crystal-singing, but is stated to not be as good at it as the elves are.
** The sea-singers of the East are [[FishPeople sirens]] who train to use their music to control sea animals. Sirens also have the natural ability to hypnotize others with their song, which is the case in the quest "Song From The Depths".
* ''VideoGame/{{Dishonored}}'' has the Overseer's music boxes, which actually act as ''anti''-magic music - whenever they're played, Corvo, Daud, Emily, and any other assassins in the area will be disoriented and unable to use any magical powers (guns and swords are still fair game, however). The music also slowly drains the player's health, although it's usually drained much more rapidly by the numerous guards who have been alerted to the player's presence by the music.
* ''VideoGame/{{Overwatch}}'' has Lucio, who is an international DJ support character who heals or speeds up his allies using the power of song! His gun also produces "sonic projectiles", a soundwave with severe knockback, and a projected sound barrier that adds temporary health to his allies, although these are described as being simply "sonic" rather than the powers of his music.

[[folder:Web Comics]]
* One of the trademarks of the Heterodyne family in ''Webcomic/GirlGenius'' is their way of "Heterodyning", or [[http://www.girlgeniusonline.com/comic.php?date=20030228 humming]] in a [[http://www.girlgeniusonline.com/comic.php?date=20070606 very complicated]] way which helps the Spark at work to concentrate. While not music that causes magic by itself, certainly a side effect and assistant to the [[MadScientist Sparkiness]].
* ''Webcomic/SoulSymphony'': In the Soul World, music can be used as magical spells. Olivia, a musical prodigy, gains flight and barrier powers from playing scales and trills on her clarinet.
* In ''Webcomic/TheChallengesOfZona'', Mentl, a second-rate busker from our world finds himself, like Jon-Tom in the ''Spellsinger'' series, transported to a magical world where he finds that his skill at and knowledge of modern music has devastating effects both [[http://www.soulgeek.com/comics/zona/2007/07/24/page-138 on the ladies]] and [[http://www.soulgeek.com/comics/zona/2009/05/26/page-276 on his enemies]].
* In ''Webcomic/TheAdventuresOfDrMcNinja'', Doc finds himself in a bind when he is attacked by ghosts and runs out of holy weapons to use. [[JourneyToTheCenterOfTheMind Sucked into his own mind]] by one of the ghosts, he [[http://drmcninja.com/archives/comic/20p66 receives advice]] from his dad and spends the next 3-4 pages doing nothing but humming the catchy ''Franchise/{{Ghostbusters}}'' theme, which (of course) enables him to [[spoiler:punch, chop, and finally ''stab'' the final ghost]].
* ''Webcomic/WoodenRose'': [[http://www.woodenrosecomic.com/comic/chapter4/88.html Aidan is playing it in the dream.]]
* This is Duzz's ability in ''Webcomic/LuminaryChildren''.
* ''Webcomic/StandStillStaySilent'': A possible part of the Finnish magic package according to Chapter 13. Onni is seen playing the kantele as part of a summon, but the exact purpose of that step has yet to be specified. The EncyclopediaExposita giving basic information about the two magic traditions shows the generic Finnish mage to have a small kantele on its belt.
* The Bard Elan in ''Webcomic/TheOrderOfTheStick'' naturally uses this trope. As per Dungeons And Dragons rules, his songs give actual bonuses to his allies. Slightly {{Downplayed}}, though, as when he learns to cast conventional spells, he does ''not'' sing them.

[[folder:Web Original]]
* In ''Podcast/TheMagnusArchives'' the narrator of the episode "Strange Music" finds a calliope organ in her dead grandfather's loft. It somehow works without air being blown in. Leanne enjoys playing it, but when she plays it to her visiting boyfriend it distresses him and he tells her to stop. A few weeks later they break up, and [[spoiler:not long after that he is found dead.]]
* In ''Roleplay/TheGamersAlliance'', bards know how to sing and play songs of power, and the magic of the songs can affect the target in various ways such as making them feel relaxed or disoriented among other things. The more complex the song is, the stronger its effect.
* Siren's powers in ''Literature/{{Phaeton}}''.
* [[http://www.scp-wiki.net/scp-1987-j SCP-1987-J]], creates a memetic effect, repulsing people, when played on most instruments (it is written for the electric guitar), and can be played on an electric guitar by anyone who knows how it is supposed to sound, even if they have never been known to be able to play the guitar. When played on the guitar as it is supposed to be, it has been known to cause [[ThePowerOfRock seemingly magical, and apparently permanent, effects]], to no currently-known pattern:
** Genital enhancement and/or increase in players perceived sex appeal;
** Lightning, fog and other stage effects;
** player may become immune to bullets;
** Some observers may have their faces melted off;
** Album cover cliches, such as dragons, swords and female angels may appear;
** Females in the area of effect may regress (or progress) to around 18, in 68% of cases their clothing will change into leather fetish gear, lingerie and G-string bikinis;
** Vehicles caught in the area of effect may polymorph into vintage muscle or custom hot rods and hogs;
** Spontaneous pregnancies may occur in fertile females... infertile females... [[MisterSeahorse males]]...
** Dead people may rise, either simply brought back to life or reanimated as zombies loyal to the player.
If you play too long, a character labelled SCP-1987-J-1 (calls himself names like "Count Rockula" and "Lord of the Strings") will appear and demand you stop playing or challenge him to a guitar duel, which he invariably wins, causing the player to [[BalefulPolymorph polymorph]] into a middleaged white guy named Earl who works in a garage. These are now being treated as D-class due to there being far more than is needed to maintain the sites motor pool.

[[folder:Western Animation]]
* The magical effects of the Foreigner Belt in ''WesternAnimation/AquaTeenHungerForce'' are activated by reciting certain lyrics from Music/{{Foreigner}} songs. It doesn't work so well when Err tries using Music/{{Loverboy}} lyrics.
* In ''WesternAnimation/BatmanTheBraveAndTheBold'', The Music Meister/Sings a song that the world wants to hear/Let's not fight, let's get along/For our hypnotic profitier.
* "Mugic" is one major aspect of the ''WesternAnimation/{{Chaotic}}'' universe.
* The power used by Floatzart, a villainous ghost from ''WesternAnimation/FilmationsGhostbusters''.
%%* The Saturday morning cartoon ''WesternAnimation/{{Hammerman}}''.
* The similarly-named Music Master from the ''WesternAnimation/JusticeLeague'' two-parter episode "Legends", who uses an accordion to generate repellent sonic waves.
* This trope is a major component of ''WesternAnimation/LittleEinsteins''.
* ''WesternAnimation/PhineasAndFerb'' had this in "Phineas and Ferb's Musical Clip-tastic Countdown", where Dr. Doofenshmirtz tried to brainwash the audience with a song deliberately designed to [[EarWorm get stuck in people's heads]]. "My name is Doof, and you'll do what I say! [[http://www.youtube.com/watch?v=yKahkEhX8Bg WHOOP! WHOOP!]]"
** In "Bubble Boys," Doofenshmirtz does this again with the song "Yodel Odel Obey Me."
* Roberon in ''WesternAnimation/RobotmanAndFriends'' uses a magical flute. He uses it to activate his power using an eerie, atonal six-note little tune (which some compare to the ''Spider-Man'' theme song!). This is despite the fact Roberon hates music because it causes him physical agony and he needs to have his sidekick Sound-Off cover his ears for him. Or, well, whatever a robot has which passes for ears. So he's a music-hating villain with music-based powers! This runs the gamut from mind control to [[FrickinLaserBeams eye-lasers]] to opening portals to the [[{{Mordor}} Land of Shadows]].
** The titular Robotman and his friends do this trope a little differently. They don't need musical instruments, and instead produce magic music from their mouths, which can perform a variety of functions from levitating objects to healing wounds to a musical robotic version of the CareBearStare for use against villains.
* ''WesternAnimation/TheSmurfs'' love magical music.
** One episode has Harmony Smurf playing a magical bagpipe that put all the other Smurfs into comas.
** In another episode, Harmony just plays his ordinary horn, and it has the effect of attracting the ExplosiveBreeder Fuzzles toward him. Papa Smurf has Harmony use the music to lure the Fuzzles away from the village, where they get captured by Gargamel instead of the Smurfs.
** Indeed, the original ''Smurfs'' movie, ''WesternAnimation/TheSmurfsAndTheMagicFlute'', was about them cutting down a huge tree to carve a tiny little magic flute... and that's for stopping somebody who has another magic flute that they made.
* In ''WesternAnimation/SouthPark'''s Imaginationland trilogy, it's necessary to sing the Imaginationland song to travel from the real world to Imaginationland.
* In ''WesternAnimation/ThunderCats2011,'' MagicalFlutist Wilykit uses her [[BizarreInstrument flute]] music to put people into a trance. Her ArtfulDodger brother Wilykat then picks their pockets while they're out of it.
* Musa of ''WesternAnimation/WinxClub'' is the fairy of sound and music. Her spells often involve music a lot. Her attacks are based on music and sound. She usually uses attacks that are disco themed and can create disco-ball force-fields, distracting musical blasts, and virtual speakers which enclose around an enemy and immobilize them through incredibly loud bass music. Musa can also create walls and barriers of the musical scale and explosive musical notes.
* ''WesternAnimation/SamuraiJack'':
** In "Jack and the Rave", an evil DJ named Stylbator plays [[MindControlMusic hypnotizing rave music]] that enslaves the local teenagers of a small town, forcing them to do evil deeds in the name of [[BigBad Aku]].
** In the Season 5 premiere episode, Jack fights the mercenary [[MusicalAssassin Scaramouche]]; who uses a [[MagicalFlutist magic flute]] to [[ImprovisedGolem form a golem out of stone rubble]] to attack Jack, {{scat}}-singing to [[MindOverMatter telekinetically levitate and control]] his scimitar, and a dagger shaped like a tuning fork to shatter Jack's combat knives using its high frequency.
* In ''WesternAnimation/ScaryLarry'', Carnages turns women into his slaves through song.
* In ''WesternAnimation/PeppermintRose'' the Peppermint Glow song transforms the evil beetles into good ones and their weapons into roses, with the bonus of making them smell better.
* ''WesternAnimation/RosePetalPlace'' is built around Rose Petal's magical singing voice, which invigorates the garden and helps it grow.

[[folder:Real Life]]
* ''Website/{{Cracked}}'' shows us a more mundane version of this trope with the [[http://www.cracked.com/article_18405_7-insane-ways-music-affects-body-according-to-science.html 7 Insane Ways Music Affects The Body (According to Science)]]. While certain music can't cure cancer, they can cure Parkinson's.
* Music can have a profound, if temporary, effect on neural performance. This is frequently referred to as the Mozart Effect, and possibly qualifies as a real-life version of a buff or debuff. Alternatively, sound of the wrong kind can increase stress and even cause health issues (see BrownNote).
* Shortly after the folk song ''Fhear a bhata'' had been composed, the mentioned boatman came back and married the composer.
* If you're willing to stretch the definition of "music," there's [[http://en.wikipedia.org/wiki/Acoustic_levitation acoustic levitation]], by which a loud sound can be used to lift a small object.
* There is also the story of the ''Marine Electric'', where one sailor clinged on for bare life off the coast of Canada. When he was about to give in, the refrain of ''The Mary Ellen Carter'' by Stan Rogers began to chime in his head: "Rise again, rise again". [[https://en.wikipedia.org/wiki/The_Mary_Ellen_Carter#Connection_to_the_sinking_of_the_Marine_Electric This gave him the strength to carry on until rescue arrived]].
