Figure 13. The Twist Flute is activated by breath.
The Twist Flute design etude features a breath-activated instrument. Users blow into the microphone located above their nose to play the instrument, extend their hands to lower the pitch, and twist their hands relative to each other to distort the timbre.
This design was an attempt at making a whimsical instrument that would be hard to create in physical reality. It does not, however, have a high range of expressivity or a high skill ceiling, making the Twist Flute more of a toy than an instrument.
