The sapeh (sape) is a plucked lute played in the Kenyah-Kayan region of north-central Borneo. Its boat-shaped body ornately carved from an aro tree trunk, has a circular resonator hole with a hollowed-out open back. This sapeh has four metal strings that fed through the peg head that has holes in front to the pegs inserted on each side. The back of the peghead is open and on top supports an ornate wood carved finial. The sapeh is most often used to accompany dances such as the musuh (a stylized fighting dance performed by two men with swords and shields), the ngajat (a solo war dance performed by a man or a woman), and several types of line dances. However, it can also be played purely for entertainment.  Sometimes two sapeh are played together, as one plays melody and the other a drone-like ostinato.
