Description better suits (future) jeli ngɔni (see INST-450) rather than this one.
Alternative: Six-stringed lute-harp from Wassoulou, West Africa. Traditionally played by hunters. Its resonator is made of three quarters of an empty calabash covered by a stretched animal skin for the sound table.
(It seems difficult to do a shorter description. It distinguishes from both kamalen ngɔni and kora.)
