A slender, rectangular wooden board. There are five round perforations on one narrow side and five round slots burnt into the other. Above the surface of the board [there is] a string made of twisted animal tissue, [which] is stretched out five times. Its direction [is] reversed by two neighbouring perforations/slits. Crosswise under the string [are] two plano-convex wooden bars. The board, resting in a right-angled recess in the edge of a calabash open at the top, moves into the resonator and abuts against its rear wall. A cord end [is] guided from there inside the resonator to a central bottom perforation and outside to the free end of the board. There [it is] tied around a carved tenon. The calabash [is] replaced (reconstruction of the resonator connection according to Ankermann: 25). [A] transverse wood binding of the other end of the string, below a perforation. from Ulrich Wegner: Afrikanische Saiteninstrumente, Staatliche Museen Berlin - SPK, 1984 (Appendix Object Catalogue)
