Bullroarer of the Kuma of the eastern Democratic Republic of the Congo. It consists of a slightly concave ellipsoidal piece of wood measuring 30 × 10 cm along the axes. The instrument is whirled by a cord attached to one end and the sound produced is said to resemble the growling of a leopard. The bullroarer has associations with spirit voices and secret ceremonies such as circumcision, and has restrictions against women and non-initiates seeing it, as is customary for other bullroarers of the Congo. The varied names collected by de Hen suggest an onomatopoeic derivation, for example, the Adoi, Amanga, Andebogo and Andowi kundrukundru, Aimed kunzukunzu, Bagbwa and Mamvu egburuburu and arumvurumvu, and Bangba and Mayogo mbirimbiri. This pattern is not always followed, as with the Mbole inano, Nyali upa and Zande gilingwa.F.J. de Hen: Beitrag zur Kenntnis der Musikinstrumente aus Belgisch Kongo und Ruanda-Urundi (Tervuren, 1960), 171ff...
