As in "pelog", although the intervals vary from one gamelan to the next, the intervals between notes in a scale are very close to identical for different instruments within the same "gamelan". It is common in Balinese gamelan that instruments are played in pairs which are tuned slightly apart so as to produce interference beating which are ideally at a consistent speed for all pairs of notes in all registers. It is thought that this contributes to the very "busy" and "shimmering" sound of gamelan ensembles. In the religious ceremonies that contain "gamelan", these interference beats are meant to give the listener a feeling of a god's presence or a stepping stone to a meditative state.
