Theme: Music is an unpredictable delight that moves its creators and its listeners in such a way that it may never be played or heard exactly the same way twice. A cat creates a sound all his own and then experiences how the rhyme and rhythm enchant his audience. Jazz is America's most original music form. LeVar explores examples of improvisation in music, literature, art and dance, and we meet Joshua Redman, a jazz saxophonist who talks about how music has influenced his life.
