In this short subject (which mostly represents a departure from Disney's 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.
Unfortunately the movie Toot, Whistle, Plunk and Boom is not yet available on HBO Max.
