Our hand-crafted Kalimba (thumb piano) has seven tunable keys with a solid wood top mounted on a strong, smooth coconut gourd shell, 6-8" wide.
Playable out of the box, but can also be tuned by gently loosening the screws, moving the tines in (higher pitch) or out (lower pitch), and tightening the screws. The sound created is very melodic and resonant, very "tribal" sounding.
Colors and markings may vary from pictured.
