PURPOSE: Demonstrate how the clarinet overblows at a musical twelfth.
DESCRIPTION: This clarinet consists of a thin-walled plastic tube into which a clarinet mouthpiece can be inserted at one end. About one-third of the length of the tube from the mouthpiece end is a hole which represents the register hole of the clarinet. Closing the register hole produces a low tone, the fundamental. Opening the register hole produces the third harmonic, a note a musical twelfth (one octave plus a fifth) above the fundamental.
SUGGESTIONS: Bring your own clarinet mouthpiece and reed. Otherwise you will have to scrape the green stuff off our reed and use it.

EQUIPMENT: Plastic tube clarinet.
