Viewers are asked to think about what the basic ingredients of music are. Excerpts from a Gregorian Chant, Medieval Song, and works by J.S. Bach, Mozart, Rachmaninoff, Bartok, as well as the jazz piece "Take Five" are used to stimulate this thought process. Morton Subotnick's electronic work "Silver Apples of the Moon" is used to encourage speculation about what is music...or not.
