A Dunun (also known as dundun, doundoun, or djun-djun) is the generic name for a family of African bass drums that developed alongside the djembe in West Africa. It is known and pronounced as "dundun" in Yorubaland of Nigeria. More specifically, there are three named the kenkeni (smallest), sangban (medium) and doundounba (largest). The kenkeni has the highest pitch and usually holds the rhythm together with a simple pattern. The sangban typically has a more complex part which defines the rhythm. The doundounba often serves to add depth with deep, widely spaced notes. These drums provide a rhythmic and melodic base for the djembe ensemble.
