The Music Meister is a character who causes others to break out into spontaneous song and/or dance. Often used as a justification for a MusicalEpisode, in which case GenreSavvy characters will question (possibly in song) why they are suddenly acting like characters in a musical.

To qualify as TheMusicMeister, a character must have an explicit power to cause others to break out in song, and the musical interludes should be [[LampshadeHanging commented on as being out of the ordinary]].

Related to CrowdSong, SpontaneousChoreography and InvoluntaryDance, since that's what this person causes.



[[folder:Anime and Manga]]
* Remarkably for a Japanese work (where {{Musical Episode}}s are uncommon in the first place), ''Anime/DuelMasters Victory V3'' has an episode about a wannabe singer whose magical companion causes others to break out into spontaneous shouts, and eventually, singing and dancing. The main characters even sing the jingles during the eyecatches.

[[folder:Comic Books]]
* The Muse from the ''Series/DoctorWho'' comic strip "Planet Bollywood" in ''Magazine/DoctorWhoMagazine''. The Muse was a robot created by the ruler of a planet to induce courtiers to perform musical routines against their will. An insurgent faction realised her powers could be used for evil. Smuggled off-planet, she was damaged in a spaceship crash and started inducing random musical outbursts in the local inhabitants.
* In one ''{{Nodwick}}'' story, Yeagar becomes this accidentally, after he asks Artax to cast a spell on him, to give him more impressive speaking skills. Of course, Artax never really read the full description of what exactly the spell ''does''... so of course, EVERYONE (heroes and villains alike) start randomly singing together in the middle of the fights. The expressions during some of the songs are truly priceless.

* The Uncle from ''[[http://www.fimfiction.net/story/124263/1/songs-uncle-sings/sineva Songs Uncle Sings]]'' is a [[IncrediblyLamePun low key]] example.

* Giselle from ''{{Enchanted}},'' who comes from a universe where random musical numbers are common. Only a few characters seem to notice that the singing and dancing is out of the ordinary.
* On ''Film/TheMask'', the title character is surrounded by police, so he starts singing a rumba number and the policemen start singing and dancing along, to their great surprise.
* In ''Film/{{Leprechaun}} In Da Hood'', the Leprechaun uses his powers to make the people in a night club sing and dance for him.

* Not a person, but otherwise along the same lines, is Rojahama's Song-and-Dance from the Literature/DoctorWhoNewAdventures novel ''Sky Pirates!''. It's a force of nature, or perhaps some kind of meteorological effect, that causes spontaneous outbreaks of CrowdSong. (The planet on which this occurs is in a solar system that, for reasons explained later in the book, is basically one giant WeirdnessMagnet.)

[[folder:Live-Action TV]]
* The demon Sweet from the ''Series/BuffyTheVampireSlayer'' musical episode "Once More With Feeling" Upon his arrival in Sunnydale, everyone in town begins breaking into musical numbers. While this seems harmless enough, the songs are always brutally honest ones that reveal people's deepest secrets, which sows discord among the populace. They also cause certain victims to spontaneously combust.
* Solan in ''Series/XenaWarriorPrincess'' qualifies as this, as he is the driving force behind Xena and Gabrielle's being transported to the musical world of Illusia [[spoiler: after they tried to kill each other]].
** Also from Xena, Terpsichore's Lyre, from "Lyre, Lyre Hearts on Fire" is an inanimate version of this, as the musical aspects of the episode only begin when the Lyre is unearthed by Draco, and are abruptly ended when the Battle of the Bands is won. [[spoiler: By Xena]]
* The Imagin Ryutaros from ''Series/KamenRiderDenO'' has the unique power to make everyone around him spontaneously burst into breakdancing with his theme song in the background just by snapping his fingers. After the first time, he even has a 'posse' that shows up whenever he wants someone to dance with.
* In an issue of ''Magazine/DoctorWhoMagazine'', Rory Williams' actor Arthur Darvill confessed to discussing the idea for this type of episode, with a monster/alien that makes everyone sing.
* In the third season of ''Series/{{Community}}'', Mr. Rad not only acts as a Music Meister, but slowly [[TheVirus converts the study group into Mini Music Meisters]].
* The Luvvie tribe in ''Series/TheLegendOfDickAndDom'' episode "The Land of the {{Luvvies}}" has this effect on people.

* Jude in the AudioPlay/BigFinishDoctorWho episode [[Recap/BigFinishDoctorWho036TheRapture "The Rapture"]].

* The Balladeer and, to a lesser extent, the Proprieter in ''Theatre/{{Assassins}}'' have elements of this.

[[folder:Western Animation]]
* The TropeNamer is the Music Meister from the ''WesternAnimation/BatmanTheBraveAndTheBold'' episode "Mayhem of the Music Meister", a hypnotist who can command people to do his bidding via song. He doesn't have to sing his command, he just has to sing anything.
* In ''MyGymPartnersAMonkey Presents Animal School Musical'', the magical fish David Coppertrout grants [[JerkWithAHeartOfGold Jake's]] wish to turn the world into a musical. The other characters are not impressed, even to the extent of singing songs about how terrible it is living in a musical.
* In ''ThePenguinsOfMadagascar'' episode "The Return of The Revenge of Dr. Blowhole", Dr. Blowhole's new device accidentally fuses with an experimental power cell and an MP3 player to form a machine capable of doing this. Blowhole himself becomes this when he takes control of it. Like the TropeNamer, he's voiced by NeilPatrickHarris.
