Back in 1953, Walt Disney Productions released two short and cutting-edge music education films. The initial film, Melody, was the first cartoon ever filmed in 3D. (Unfortunately, current versions only appear in 2D).
Then came the sequel, Toot, Whistle, Plunk and Boom, which proved innovative in its own way. The short film, tracing the evolution of the horn, flute, guitar and drum, was the first cartoon filmed and shown in widescreen CinemaScope. It won the 1954 Academy Award for Best Short Subject (Cartoons) and was later voted #29 of the 50 Greatest Cartoons of all time.
