Toot, Whistle, Plunk and Boom

Mr. Owl discuses the study of musical instruments – the subject of the day. Mr. Owl tells the class (and the viewer), in rhyme, about all music that originates from four core sounds: toot (brass), whistle (woodwind), plunk (strings), and boom (percussion).

The first Disney cartoon to be filmed and released in widescreen CinemaScope, Toot, Whistle, Plunk and Boom won the 1954 Academy Award for Best Short Subject (Cartoons)
