A [[StandardSnippet very well-known piece]] of ClassicalMusic. Written by Johann Pachelbel, it is the first movement of "Canon and Gigue in D", the less-famous second movement being more lively and dance-like. The canon involves a two-bar-long [[PachelbelsCanonProgression ostinato]] (repeating bass progression), over which three instrumental parts each play the same melodic material but starting at different times, each one displaced from the one before by a distance of two bars (one rotation of the ostinato) throughout the canon; this material is written in such a way that the three parts harmonize. The piece is usually performed with a string orchestra, but arrangements of it exist for almost every standard ensemble you can think of. Though Pachelbel was largely forgotten after his death (noted primarily for being a family friend/music tutor of the Bachs and thus indirectly influencing the works of [[Music/JohannSebastianBach J. S.]]), this piece's rediscovery in 1919 skyrocketed him to fame, albeit of the OneHitWonder variety.

Enjoy it by clicking [[http://www.youtube.com/watch?v=8Af372EQLck here]]. Fun fact: The one we commonly hear about the canon is actually a rendition by the French conductor [[https://en.wikipedia.org/wiki/Jean-Francois_Paillard Jean-François Paillard]] in 1969. What he did was slowed down the tempo and tuned it in Romantic style. [[https://youtu.be/soIQ52hkMXw Here]] is the rendition played according to the original manuscripts (which is actually a half-step lower, in the key of D-flat major).

It is also known by the names "Canon in D", "Pachelbel's Canon in D", and "Kanon D-dur" (the German name, meaning "D major Canon"). The piece is, of course, in D major--ExactlyWhatItSaysOnTheTin. This hasn't stopped it from being [[MisattributedSong misattributed]] to everyone under the sun, particularly [[Music/WolfgangAmadeusMozart Mozart]].

It's commonly featured in collections of "light" or "soothing" music, and is often played at weddings, second only to LohengrinAndMendelssohn. It is also a popular selection for use in {{Public Domain Soundtrack}}s. It's the ''[[Music/LynyrdSkynyrd Free Bird]]'' of classical music, exacerbated by its own repetitiveness: [[PachelbelsCanonProgression cellists in particular detest it because it involves playing the same 8-note progression 27 times without variation]].

The piece is the TropeNamer and TropeCodifier for the PachelbelsCanonProgression.

By the way, "canon" the [[http://en.wikipedia.org/wiki/Canon_(music) musical term]] has nothing to do with "{{canon}}" the literary term for a creator's definitive body of work. Also, don't confuse it with pieces of music that use ''cannons,'' which you'll find under OrchestralBombing. Funnily enough, most versions nowadays [[NonIndicativeName aren't actually canons]].
!!It has been used in the following works:
* "Lullaby" by the string quartet Bond is an adaptation of the work.
* Music/BrianEno did three versions of the piece in his album ''Discreet Music''.
* The influence of the piece can be heard in many of Music/EmilieAutumn's songs, since as a child she would mentally play the piece each night to suppress her auditory hallucinations (as quoted from [[http://en.wikipedia.org/wiki/Emilie_Autumn The Other Wiki]]). A few bars of the melody are shoehorned into "Save You", and the first half of the ostinato is used in "Ancient Grounds" and "Let the Record Show".
* It features in and is one of the themes of ''VisualNovel/{{Kanon}}'', which names itself after the piece.
* In the anime ''Anime/LuckyStar'', Tsukasa's ringtone sounds like a cheerier version of this.
* In the ''Anime/NeonGenesisEvangelion'' film ''[[CompilationMovie Evangelion: Death and Rebirth]]'', a recurring motif of the three main characters playing the piece is used to punctuate the recap portion. In fact, the sort-of framing sequence for the recap is the three characters (plus an EnsembleDarkhorse) getting together to practice the Canon (with ButtMonkey Shinji playing the cello).
-->'''Asuka''': Your part is easy. All ''you'' have to play is arpeggios.
* Comedian Rob Paravonian famously made a [[http://www.youtube.com/watch?v=JdxkVQy7QLM rant]] about the piece, noting how boring it is to play the bass line as the cellist in the ensemble, as well as [[PachelbelsCanonProgression the progression's]] ubiquity in popular music (although [[SquarePegRoundTrope few of the examples given actually use the progression]]).
* ''WesternAnimation/SouthPark'' uses a SuspiciouslySimilarSong in the scene where Cartman has a tea party with his stuffed toys.
* Music/TayZonday's arrangement "[[http://www.youtube.com/watch?v=RSCzMT8IMME Canon In Z]]."
* Music/TransSiberianOrchestra has ''two'' songs based on it: "Christmas Canon" from ''The Christmas Attic'', and "Christmas Canon Rock" from ''The Lost Christmas Eve''.
* ''[[Franchise/TheLegendOfZelda Pachelbel's]] [[IncrediblyLamePun Ganon]],'' an Music/OverclockedRemix track by djpretzel that rearranges Zelda's Lullaby and ''VideoGame/TheLegendOfZeldaOcarinaOfTime's'' opening theme in an R&B style, with this as its backing track.
* In [[Disney/{{Tangled}} Tangled Ever After]], it's the BGM for the opening narration.
* [[https://www.youtube.com/watch?v=qNeBdp7L4_U "Canon Rock"]], a rock remix of the piece that quickly became popular on the Internet - to the point where newspapers took notice of it. Wiki/TheOtherWiki [[http://en.wikipedia.org/wiki/Canon_Rock_%28music%29 has an article.]]
* A horribly distorted organ version appears in the creepiest part of ''VideoGame/BioshockInfinite''.
* In the year 2000, the piece was heavily sampled by Vitamin C for her hit "Graduation (Friends Forever)", which resulted in the WeirdAlEffect for millions of millennials who associate the Canon with their high school graduations.[[invoked]]
* It's used as a theme in ''Film/OrdinaryPeople''.
* Kevin Bacon's character plays it briefly on trumpet in ''Film/QueensLogic''.
* Used during the "not-wedding" on ''Series/{{Charmed}}'' in Season 3.
* Used as background music during "Decomposing Composers" by Creator/MichaelPalin sang on Creator/MontyPython's ''Audioplay/MontyPythonsContractualObligationAlbum''.
* Used in the final episode of ''WebAnimation/LlamasWithHats'' [[spoiler:from the point where Carl discovers Paul's dead body until Carl kills himself.]]
* Used as background music in ''WebAnimation/ZeroPunctuation'' star Creator/BenCroshaw's new Escapist format ''Judging By The Cover''.
* The first two games in the ''VideoGame/{{Atelier}}'' series make use of it for their hardest to attain endings.
* ''Canon D (Part of the Memories #1)'', one of the [[PublicDomainSoundtrack tracks]] composed for the ''VideoGame/PumpItUp'' series by Andamiro's in-house band [=BanYa=], with a regular and full track version (a first for the game's original tunes). The song is highly popular with ''Pump It Up'' fans, not only for the song's Classical rock- style melody, but because of the [[{{Animesque}} anime-style]] video that accompanies it, for both having [[VisualEffectsofAwesome animation that's considered to be higher quality than most other BGAs in the franchise]] and for its narrative that provides doses of TearJerker and CrowningMomentofHeartwarming. The video is even the Trope page for the game! A later remix called Canon X.1 was later released, only it's not a follow up to the first story (despite the video officially being titled Canon-D Part of the Memories #1), and instead tells a separate story that's [[ShoutOut inspired by]] "Anime/NeonGenesisEvangelion."
* A skit on ''Radio/JohnFinnemoresSouvenirProgramme'' portrayed Pachelbel himself as [[CreatorBacklash utterly sick]] of the Canon, being much more enthusiastic about his Fugue, his Sonata, or his Hexachordum Apollonis, eventually being forced to play it and singing about how much it annoyed him that this was all he was remembered for. ("All that it does is go dooby-dooby-dooby-dooby...")
* ''VideoGame/Mother3'' uses it in the theme of the Magypsies.
* Goldenrod City in ''VideoGame/PokemonGoldAndSilver'' and its remakes utilizes it.
