''Symphony Hour'' is a [[TheGoldenAgeOfAnimation 1942]] MickeyMouse short. In premise, it is similar to ''Disney/TheBandConcert'', although things take a much different turn for the worse.

Mickey stars as the conductor of an orchestra sponsored by "Sylvester Macaroni" (played by {{Pete}}). Macaroni loves the orchestra's rehearsal of von Suppe's "Light Cavalry Overture", but after the instruments and {{Goofy}} have an encounter with an elevator, the live performance quickly becomes an unmitigated disaster.

!! Tropes present in this short include:
* BatmanGrabsAGun: Or rather, ''Mickey'' grabs a gun.
* BrownNote: Dear lord, the entire performance compared with how the song actually sounds.
* ChewingTheScenery: Quite literally as "Sylvester Macaroni" reacts to the horrible performance.
* TheDeterminator: Mickey.
* FurryReminder: Horace Horsecollar briefly laughs at Donald's Asian caricature, sounding like a horse's whinny.
* NiceJobBreakingItHero: Sure, Goofy wrecks the instruments, [[spoiler: but the audience loves it anyway.]]
* OOCIsSeriousBusiness: The infamous moment in the short where Mickey, in a desperate effort to keep Donald from walking out on the concert, blocks his path and ''holds him at gunpoint''.
* ScrewThisImOuttaHere: Donald attempts this after everything goes wrong, but Mickey forces him at gunpoint to keep playing.
* StopOrIWillShoot: In one of the funnier moments of the short, Mickey stops Donald from leaving by pulling a gun on him.
* TheShowMustGoOn: Mickey is one determined conductor.
* WhatHappenedToTheMouse: Clara Cluck was only around for the rehearsal, she wasn't seen at all at the live performance.
