The first ever cartoon in CinemaScope. In this short subject (which mostly represents a departure from Disneys traditional approach to animation), a stuffy owl teacher lectures his feathered flock on the origins of Western musical instruments. Starting with cavepeople, whose crude implements could only toot, whistle, plunk and boom, the owl explains how these beginnings led to the development of the four basic types of Western musical instruments: brass, woodwinds, strings, and percussion.
