The Lukumbi: a six-toned slit drum of the Batetela

Three types of drums are used by the Batetela, a Bantu tribe situated between the Lomami and the Sankuru rivers in the Kasai Province of central Belgian Congo. The ngomo skin drum is used for dancing, usually accompanying the lukumbi, the six-toned slit drum.
