The Djun-Djun or Djum-Djum (pronounced dununs or dundun) is a cylindrical, double-headed bass drum carved from solid Dembu log and using with cow skin membranes. The Djun-djun is found throughout South America and West Africa. Djun-djun are worn over the shoulder and played with two sticks: one for the bass tones and the other for a bell tied to the side of the drum. Also seen are sets of two or three different sized djun djun drums, played while sitting with drums resting upright on the floor. Often the player also has a whistle with which to blow calls and breaks to dancers.
The dundun (larger of the two bass drums found in the Malian jembe ensemble) is made from either a hollowed out wooden cylinder or cylindrical metal barrel, measuring twenty to twenty six inches in diameter and thirty to thirty six inches long.
The tension on the playing heads of the dundun is maintained through the interweaving of the synthetic ropes connecting the two heads, in a manner identical to that used for the jembe.
In Bamako, the dundun player usually accompanies himself with a conical iron bell suspended by a string attached to the middle finger on the left hand and struck by an iron thumb ring.
