Happy Harmonies is the name of a series of thirty-six animated cartoons distributed by Metro-Goldwyn-Mayer and produced by Hugh Harman and Rudolf Ising between 1934 and 1938.[1]

Produced in Technicolor, these cartoons were very similar to Walt Disney's Silly Symphonies. They would occasionally feature Bosko, a character who starred in the first Looney Tunes shorts that the duo produced for Leon Schlesinger. After the first few releases, the design of Bosko changed from an ink blot to a realistic African American boy.

The two final titles in the series was originally produced by Harman and Ising as Silly Symphonies cartoons. But when Disney only bought one of their three shorts, Merbabies, the others were sold to MGM who released them as Happy Harmonies.[2]
