The Overtone Mouth Violin Kni is a traditional, mouth-resonating string instrument of the Giaray people of Vietnam.
This is the fretless Kni.
At one side of the string there is a small round plate which will be put behind the teeth while playing. The sound can be modulated by changing the volume of the mouth.
The Kni comes with a bag and the traditional bamboo bow.
Important: The bow needs to get treated with rosin (not included) before use.
A horsehair bow is optionally available.
