Scraper of the Democratic Republic of the Congo. Various types of scrapers bear this or a similar name. The Lia and Oli peoples call it bonkwasa and the Nkundo call it bonkwata. The Konda and Kala know it also as bokwese. Typically it is a bamboo tube with one or several slits notched on both edges or sometimes only on one edge. Wooden ones are rare and mostly confined to the Lower Congo. Here variant forms exist, such as a wooden box with a grooved stick attached to a board; an anthropomorphic body covered with skin; or a box shaped like a goat, with a notched bamboo tube replacing the vertebrae and scraped with two sticks, one solid and the other partly slit. Lemba-type wooden slit drums sometimes have the sides of the slot notched to serve also as scrapers.F.J. de Hen: Beitrag zur Kenntnis der Musikinstrumente aus Belgisch Kongo und Ruanda-Urundi...
