Goblet-shaped drum; gedumbak

Gedumbak, goblet-shaped drum. Turned wooden body (probably of jackfruit, Artocarpus heterophyllus) with a curvilinear stem, which widens slightly to a foot. The upper part of the body is a wide bowl, which constricts at the top to form a curved rim. The hide membrane covers the rounded part of the rim. String laced through holes around the edge of the head is looped around split canes braced to a wooden ring at the base of the bowl.The cord shoulder strap is knotted at each end to secure it to metal hooks at the top and bottom of the drum.
