Gamelan Jegog - The Instruments

The Instruments

Jegog instruments have a four note scale that roughly corresponds to the four pitches of a dominant 7th chord in Western music. All instruments have eight bamboo keys. Some instruments have two keys for each pitch slightly detuned so that the pitches beat when they are played together. Other instruments have a two octave range with four pitches in a low octave and the same four pitches an octave higher. In this case the instrument will be paired with another instrument that is slightly detuned. Taken together the ensemble has a range of five octaves.

Most Jegog ensembles have instruments that have keys that are made of bamboo that are split at one end and then half of the tube is removed. The other end remains intact and functions as a resonator for the split part. The keys are suspended on a wooden frame and struck with mallets (called pangguls), made out of wood or rubber. There are also Jegog ensembles with instruments called Jegog Tingklik. These smaller instruments are used primarily with children. The keys are made of bamboo slats mounted above a resonator box.
