An egg-shaped calabash, impaled halfway through by the bent round wooden stick. The edge of the reptile skin membrane, which is folded far outwards, [is] pegged with wooden pins above the upward-facing resonator opening. The bar ends [are] wrapped several times from the string [with] twisted bast fibre. At one end a notch, at the other a carved small knob. The membrane in the centre [is] slit twice to allow the string to pass through. A long, flat mallet with a pointed upper end and a widened grip surface [also exists]. There is a sound hole in the resonator. from Ulrich Wegner: Afrikanische Saiteninstrumente, Staatliche Museen Berlin - SPK, 1984 (Appendix Object Catalogue)
