Innovative modern variation of ancient african instrument
Has a rottan string and fretboard, so it's possible to play the chromatic scale.

The sound is modulated by the cavity of the mouth. You can get the overtone scale of each note and
use the fretboard to change notes. Legato and many forshlags are possible.
Played by bamboo stick (included). Mouthbow made in France.
