Woodwinds and Brass -- Film Description:
"At one of Ottawa's Saturday concerts for children, the conductor, Eugene Kash, introduces the woodwind and brass instruments and has musicians play each of the main types. Beginning with a willow whistle, he explains that modern wind instruments—flute, clarinet, trombone and others—are just more complex versions of this simple pipe. (The series consists of revised excerpts from Children's Concert.)"
