The jegog is a brisk and raucous gamelan ensemble originating in Jembrana, and although it is not unusual to see dancers perform with it in shortened compositions for the tourist market, the jegog itself requires no dancers.
The obvious difference between the more commonly found gamelan and the jegog ensemble is that the jegog instruments are made from wood and bamboo rather than wood and metal. The jegog is pure bamboo percussion and there are no gongs. The other striking difference is size. The bass jegog, for example, is so large that the player sits astride it, mounted like one would sit on a cart. The bass bamboo tubes are at least 25 centimeters in diameter and around 3 meters long, the upper part is split and half removed whilst the lower part is whole and acts as a sound box.
The instruments are mounted on frames and played with a mallet. For important performances, the instruments are adorned with religious carvings, the Barong Ket, Rangda or Surya.
