The instruments of the Fan ( Fang / Pangwe ) and their neighbours in Cameroon, Gabon and Equatorial
Guinea are noted for their artistic, hand-crafted decorations. Commonly found on the sides of the instruments are carved, tapering triangles, these, too, being variously decorated.
Instruments of this sort, known among the Fan as mbe are traditionally played often in combination with slit-drums. (vgl. Andreas Meyer - Afrikanische Trommeln West- und Zentralafrika, Berlin 1997)
