An elongated bowl with slightly raised, steeply sloping cross walls on the inside and a rounded base. On each narrow side [are] six diagonally burnt string guide perforations. Six strings. One end of the string cord [is] looped into a knot behind an outer perforation, the other wrapped around an upwardly curved stem extension carved in the longitudinal direction. A calabash resonator was tied through two bottom perforations with a thick loop of plant material. Only one small calabash sherd survives. from Ulrich Wegner: Afrikanische Saiteninstrumente, Staatliche Museen Berlin - SPK, 1984 (Appendix Object Catalogue)
