Melody

Melody is an American animated short film produced by Walt Disney Productions and directed by Ward Kimball and Charles A. Nichols. Originally released on May 28, 1953, this film was the first in a proposed series of animated cartoon shorts teaching the principles of music, called Adventures in Music. Only one other entry in the series was produced, Toot, Whistle, Plunk and Boom, which was released later that same year, winning an Academy Award for Best Short Subject (Cartoons) the following year.
