Large single-headed frame drum of North Africa. The head, which is usually goatskin, is stretched over a flat wooden hoop usually no more than 15 cm wide. The diameter of the rim varies but is rarely more than 60 cm across the head. The frame usually has a single bored thumb-hole, which facilitates one method of playing. Very often, three or four gut or nylon snares are attached to the inner side of the drum, and these resonate against the skin when the drum is played. Occasionally jingles are attached through slots made around the frame. At many ambient temperatures the skin is slack, and is tightened either by placing the drum in direct sunlight or by heating it over a brazier....
