Mad Melody(1931)

We see a lion at a piano, apparently trying to compose a melody. He gets frustrated, starts speaking vehemently in what sounds like German and begins pacing the floor-and his piano does likewise! After they settle back to work, a monkey comes in, words are exchanged and the monkey goes to the back of the piano with a brush and a dustpan. Musical notes flow out of the piano onto the floor and the monkey brushes most of them into the dustpan and drops them back into the piano.
