The folk-type dameru is shaped from two blocks of wood (can be other materials) into two hollow bowl shapes. The bases of the bowls are connected and the open 'faces' which form the outer sides of this hand drum are covered with hide. Two thongs with knotted weights are attached and these hit against the drum heads in a rapid percussive sound when rotated by the hand with a simultaneous up-and-down motion of the arm. Folk-type dameru are frequently used by itinerant mendicants in both Nepal and Tibet. The ritual dameru used in certain Tibetan monasteries are said to be made by joining two human skull tops and covering their openings with hide. The folk-type dameru, of which this is an example, is similarly shaped but made from hollowed blocks of wood or other materials. A rapidly rotating wrist motion causes the leather thong knot-ends to produce a few or a cluster of percussive sounds when hitting the head. Dameru are also used in Shaivite temples in India.
