A set of three differently tuned metal bells, specially made for dundun sets but can be used with other strung drums too. These are made from recycled galavanised tubes. Slip the metal rods under one drum string so that it ends up resting on top of the other drum strings.

There are two primary playing styles for dununs. The traditional style has each player using a single drum resting on its side, either on the floor or on a stand, and striking the head with one mallot and a bell mounted on top with the other. A melody is created across the interplay of the three dununs. For the other style, known as ballet style as it is used in the National Ballets, one player has command of the three dununs standing on the floor, allowing a more complex arrangement for the dance.

A Dunun (also known as dundun, doundoun, or djun-djun) is the generic name for a family of West African Bass Drums that developed alongside the djembe in the Mande drum ensemble. It is related in construction to the gungon or brekete bass drums of northern Ghana, except that the gungon uses a single snare on the drum face to produce a buzzing sound absent in the dunun. There are different sizes of dunduns, ranging from 25 to 60 cm. Basing on the size, construction technique and tuning, there are different names for each type of dundun. Some of the most often used names are konkoni, kenkeni, sangban, dununba, djeli-dun, etc.
