Blue Rhythm is a 1931 Mickey Mouse animated short film directed by Burt Gillett, produced by Walt Disney Productions and distributed by Columbia Pictures.

Soon an unseen band takes over the accompaniment and Mickey joins Minnie; the two mice dance and scat sing two more verses.

As Mickey and Minnie exit stage right, the curtain rises to reveal the band – Pluto on trombone, two goats on violins, a Scottish Terrier on sousaphone, a pig on the cornet, Clarabelle Cow on a double bass and a piccolo, two Dachshunds on saxophones, and Horace Horsecollar on a drum set and xylophone; Mickey reappears through a stage elevator to conduct.

Opens with Mickey at the piano pounding out a number, with Minnie rather spoiling it with the falsetto singing that is considered necessary for cartoon characters.

A short dance and then a break to a stage jazz band for the usual trick stuff, but well done and in excellent synchrony.
