The string, the string carrier and the baton are not preserved. The mammal skin membrane [is] pegged to the resonator, a halved coconut, with wooden pins. Originally [it was] a string carrier impaling the resonator. In the centre of the membrane [are] two slits that detach a skin loop. In the resonator [are] two sound holes (rectangular/round). Monochord, the string goes through the soundboard; this is placed on the chest when playing and the string is struck with a stick. from Ulrich Wegner: Afrikanische Saiteninstrumente, Staatliche Museen Berlin - SPK, 1984 (Appendix Object Catalogue)
