History Main / SpontaneousChoreography

* ''Film/SisterAct2'' also had one in that the kids had been practicing a big traditional choral presentation, but then at the last minute when faced up against a big-time school that did the same thing better than they could have, turn it into a mixed-style free-for-all version of the same basic song. Note that the accompanying music also keeps up with the different style changes, even though they just decided to do it this way a few minutes prior.

* ''WesternAnimation/TheLorax'' begins with a musical number with the entire city. After they finish they go back to their regular routines, making it seem like they all stopped what they were doing to dance.

* ''Film/TheMuppets'': Pops up as Gary and Walter walk to the school to pick up Mary, then as the three walk to the bus stop. Evidently this is exhausting in-universe. When Mary looks out the window at Walter after saying it is fine that he's coming to LA you can see the townspeople who danced along with them lying around, exhausted. Then once they leave town, everyone collapses.

* ''Wiki/SCPFoundation'', [[http://www.scp-wiki.net/scp-630-j SCP-630-J ("A Song In Their Heart")]]. When SCP-630-J activates it causes all sentient beings (even animals such as house cats) within range and all sentient beings that watch the performance live to start performing complex dance routines. It also alters the local environment to provide special effects that would be expected in a theatrical production.

* This trope is actually subverted in ''Film/ShesAllThat'' by the DJ played by Usher. He specifically says "Right about now we're going to do that dance I taught you. And I know you've been practicing."
** Though as noted by WebVideo/TheNostalgiaChick, it comes off as more of a tacked-on HandWave than a legitimate explanation. The entire student body (or at least all those attending the prom) being taught a complicated dance for that one moment just raises even more questions than it answers.

* In ''Film/TheBluesBrothers'', the crowd outside the music store breaks out into spontaneous dance once Ray Charles starts up ''Shake A Tail Feather''. But then, it's Ray Charles, so its sort of expected.

[[caption-width-right:350:Typical. You begin singing in the street, and suddenly it's a musical number.]]

* ''WesternAnimation/PhineasAndFerb'' do it at least OncePerEpisode. Taken UpToEleven in [[ExactlyWhatItSaysOnTheTin Rollercoaster: The Musical]], which features this in just about every other scene, and is naturally {{lampshade|Hanging}}d. It gets further {{lampshade|Hanging}}d in [[https://tvtropes.org/pmwiki/pmwiki.php/Recap/PhineasAndFerbWheresPinky Where's Pinky?]] where it is revealed that the Tri-State Area is famous for this kind of thing.

* ''WesternAnimation/TheLorax'': the film begins with a musical number with the entire city. After they finish they go back to their regular routines, making it seem like they all stopped what they were doing to dance.

--> 1120. Even if I’m in charge I can’t order the Assault Lance to perform West Side Story dance routines.

** And again in "[[Recap/TheSimpsonsS8E5BartAfterDark Bart After Dark]]" with those who are gathered to tear down the burlesque house and people sing 'We Put the Spring in Springfield'... except Marge who was out renting the bulldozer. She asks if they can sing it again but Ned Flanders tells her it really was one of those spur-of-the-moment type things. Ironically that musical number was recorded as seen on a clip show so she should’ve played the tape instead of asking Ned to sing it again.

** ''Anime/LoveLiveNijigasakiHighschoolIdolClub'' uses this trope more often than its predecessors, especially in the beginning of this series. In the first episodes is the [[CharacterFocus girl who has the focus]] in its episode starting singing her song spontanously in an ordinary situation and suddenly switching to a fancy stage or even to a dream world. This happens for Ayumu Uehara with "Dream with you" switching from a dark stair to a pink stage, this happens for Kasum Nakazu with "Poppin' Up" who sings in a weird dream world with many sweets, this happens for Setsuna Yuki with "Dive!", where suddenly pops a stage up and she is singing underwater too, this happens for Ai Miyashita, who sings her song in a park, where suddenly a full stage pops up and this happens for Emma Verde, who can use a stage with alps motives in the background.

* In ''Fanfic/ManehattansLoneGuardian'', Drama Heart explains what she calls "heartsongs"[[note]]A fan term for the musical numbers in ''WesternAnimation/MyLittlePonyFriendshipIsMagic''[[/note]] to Leviathan: when somepony is experiencing an emotional high of some kind, the world's magic manifests itself as music and enables said pony and others to join in. The heartsongs are also capable of generating very realistic illusions, as Leviathan finds out when Drama blasts her with an altered version of Music/{{Nightwish}}'s "Storytime" as a demonstration.

* Advertising/{{Cryptoland}}: A bunch of characters manage to suddenly dance on the beach.

** And again in "[[Recap/TheSimpsonsS8E5BartAfterDark Bart After Dark]]" with those who are gathered to tear down the burlesque house and people sing 'We Put the Spring in Sprinfield' ... except Marge who was out renting the bulldozer. She asks if they can sing it again but Ned Flanders tells her it really was one of those spur-of-the-moment type things. Ironically that musical number was recorded as seen on a clip show so she should’ve played the tape instead of asking Ned to sing it again.

* ''Manga/JojosBizarreAdventureVentoAureo'' features 3 of its main characters joining in a perfectly synchronized dance out of nowhere while torturing a rival gangster for information. The anime has it play out like a music video, even.

* Crosses over with a CrowdSong in ''Series/{{Mongrels}}'' with [[https://www.youtube.com/watch?v=x5zsxfhAh6Q Everyone Loves A Lesbian]]''.

* Creator/NormMacDonald lampshades this in a ''Series/SaturdayNightLive'' [[http://snltranscripts.jt.org/96/96fcobras.phtml sketch]].

* Though it stops short of a song-and-dance number, every {{Toku}} hero has a series of poses he or she goes through before battle. Teams will do it in unison. Even when the ByThePowerOfGreyskull phrase is taught to them, the dance they do before never is and it's really unclear how it came to them or why they would. (Franchise/SuperSentai and several but not all Franchise/PowerRangers series even have the 'roll call,' where everyone does a ''unique'' dance and InTheNameOfTheMoon phrase. You're taught a couple words... and spontaneously do [[https://www.youtube.com/watch?v=OMsyTtNY5Xc this]].) It's especially visible in ''Series/ZyudenSentaiKyoryuger'', where the pre-more pose is more of a pre-morph ''samba.''

* The ''Series/BuffyTheVampireSlayer'' episode "[[Recap/BuffyTheVampireSlayerS6E7OnceMoreWithFeeling Once More with Feeling]]". [[AWizardDidIt A Demon Did It.]]

--> "[[LampshadeHanging This is a dance we practiced in the gym]]! [...] [[RealityEnsues There's no way it could've been spontaneous!]]"

* In ''Manga/WelcomeToDemonSchoolIrumaKun'' (which is otherwise ''not'' a musical), whenever [[GenkiGirl Clara]] is reunited with her siblings and mother, the Valac family breaks out into choreographed songs. They're the ''only'' characters who do this, and other demons [[LampshadeHanging point out how weird it is]]. But the Valacs are all {{Cloudcuckoolander}}s so it makes sense ''for them'' to behave in such a strange manner. They also use their [[ThePowerOfCreation power to create objects]] to make props for their song and dance routines.
