’MOE
’Moe is a clarinet-like instrument. Its distinguishing feature is the pitch control system: an open slit runs along the top of the pipe, and a strip of flexible material extends at a slight angle out over the slit. When the player presses the strip down, it covers some portion of the slit depending on where pressed. This is analogous to covering tone holes. Since you can press anywhere along the slit, you can play any pitch along the continuum. To ensure a good seal when pressed down, the strip is made of magnetized plastic, while the body is steel. Other instruments in this collection using the same pitch control system are ’moe flute, ’moe sax and ‘moe mem.
