Gamelan Gong Kebyar - Paksi Neglayang

A gamelan is a musical ensemble from Indonesia, typically from the islands of Bali or Java, featuring a variety of instruments such as metallophones, xylophones, drums and gongs; bamboo flutes, bowed and plucked strings. Gamelan gong kebyar is a modern style or genre of Balinese gamelan music. Kebyar means "the process of flowering", and refers to the explosive changes in tempo and dynamics characteristic of the style.

Gong kebyar music is based on a five-tone scale called pelog selisir (tones 1, 2, 3, 5, and 6 of the 7-tone pelog scale), and is characterized by brilliant sounds, syncopations, sudden and gradual changes in sound colour, dynamics, tempo and articulation, and complex, complementary interlocking melodic and rhythmic patterns called kotekan.

This results in sound quite different from music played in a western tuning system. Many gamelan orchestras will include instruments in each tuning, but each individual instrument will only be able to play notes in one. The precise tuning used differs from ensemble to ensemble, and give each ensemble its own particular flavour. The intervals between notes in a scale are very close to identical for different instruments within each gamelan, but the intervals vary from one gamelan to the next.

Balinese gamelan instruments are commonly played in pairs which are tuned slightly apart to produce interference beats, 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.

The music is divided into 4 beat groups called Keteg, this whole rhythmic cycle is called the gongan. The gongs divide gongan into sections, gong ageng, the largest gong, marks the end of gongen, the smaller gongs mark the 4th or 8th keteg and the smallest gongs outline the pulse.

There is no standard pitch in any Balinese music. Generally speaking, all instruments in a gamelan gong kebyar ensemble are made and tuned at the same time. Each ensemble is tuned to itself, making it nearly impossible to remove an instrument from one ensemble to use it in another and have it match pitch. In any ensemble, however, instruments are gendered, and their individual tuning depends on that instruments gender.

Almost every instrument in a kebyar ensemble is paired with a male and female counterpart. Each instrument in a pair is tuned differently from its counterpart, one higher and one lower. Played at the same time, the higher instrument (known as pengisep or "inhaler") and the lower instrument (known as the pengumbang or "exhaler"), produce a beating effect (ombak), creating an overall shimmering, pulsating quality. The female instrument is tuned lower, while the male instrument is tuned higher. For example, one note on a female gangsa pemadé might be tuned to 220 Hz, while the male gansa pemadé might be tuned slightly higher to 228 Hz. A kebyar ensemble is usually tuned so that the number of beats per second stays consistent throughout the range of the ensemble, although sometimes an ensemble is tuned so that the beats are slightly faster for higher frequencies.
