The listing, Vintage Gourd Thumb Piano has ended.
The gourd makes it sound great-much better than wood.
Also called thumb pianos, mbiras, gourd pianos, sansas, and other indigenous names, these percussion instruments originated in Africa. Mbiras vary widely in appearance, size, materials, and tuning, but usually consist of 4 to 20 metal tongues mounted across a bridge attached to a board or resonator. Plucked with fingers or thumbs, these instruments produce a haunting, liquid percussive music. Since you can play either simultaneously or alternating between both thumbs, lovely harmonic and rhythmic effects are possible. These can be virtuoso instruments, but they're also great for just playing around.
