The two most common scales in Gameland in Java are Sléndro (pentatonic scale) and Pélog (heptatonic scale), in addition to Degong and Maidenda (also known as Diatonis, because they are similar to natural minor scales in the West). Sléndro and China's pentatonic scale are approximate, close to pure law, and similar to the western do re mi so la. Pélog has seven tones, and the distance between the tones is not equal, which is very different from the western scales, so the sound is unique. You don't have to use up seven notes when playing. Many times, only five of them will be selected in the same piece of music.

The pitch of Gamelan band in each team is slightly different, but each instrument in the same band follows a set of pitch standards. So the instruments of different Gamelan bands can't be mixed. Colin mcphee, a composer and ethnomusicologist, is aware of this phenomenon, and thinks that the difference of musical scales is the cause of various playgrounds. However, some people hold the opposite view, because there is also a Gamelan Manikasanti in Indonesia, which can play a variety of scales to facilitate a band to play different styles of music in festivals.

The biggest feature of Gamelan musical instrument in Bali is that musicians can play two groups of sounds at the same time, and the pitch between the two groups of sounds is slightly different, which produces physical beat effect, brings timbre flicker to the sound and strengthens the feeling of meditation in religious music.
