I'm listening to Lou Harrison's Canticle #3 for ocarina (or flute), guitar, pipes, woodblocks, brake drums, xylophone, dragon's mouths, maracas, elephants bells, tam-tam, cowbells, and drums.

I think of the ocarina as an annoying kid's toy but apparently not. And leave it to New Sounds to have a program entitled "What Is an Ocarina?
