GENDANG ANAKNA: A pair of double-headed conical drums called baluh (the larger) and gerantung (the smaller) respectively, collected in the Batak Karo area of North Sumatra in the 1970s. The smaller drum is normally tied firmly to the larger, though shown separately here. One of the drums’ two wooden playing sticks is partially hidden in the photo by a small rebana (frame drum) on the right. Ethno-lingual group: Batak Karo. Photo: C. Basile, 2012.
