A plant tube cut off near two nodes. A string [consisting] of twisted animal tissue passed through a perforation at one end of the tube into the interior of the tube and tied to a crossbar. The string [is] passed over the notched cross-sectional surface at the other end of the tube and then wound around the rod several times. A calabash open at the bottom. [The knot [is] fixed by the connecting string inside the resonator. The striking bar is missing. Perforations burnt diagonally over the entire length of the upper half of the tube, of different sizes and partly arranged in groups. from Ulrich Wegner: Afrikanische Saiteninstrumente, Staatliche Museen Berlin - SPK, 1984 (Appendix Object Catalogue)
