Most Balinese music is transmitted orally. Notation is rarely used in the transmission process and never in performance. However, versions of the notational system known as grantangan are used for preserving the skeletal pitches of long compositions. Syllables comprising the pitch notation systems are also used as vocalized mnemonics in teaching. There are several such systems (Table 1). The oldest, used in gamelan gambang and other seven-tone sacred ensembles, is derived from sacred vocal music notation in which the vowels of poetry are translated into musical pitches. The vowel sound in each word of text has a corresponding syllable representing a pitch that is played as a tone on a single octave metallophone. At the KOKAR music conservatory, notation systems (known as notasi ding dong and notasi KOKAR) devised in 1960 have become standard; occasionally cipher notation is also used. Drum patterns are also transmitted by rote using a system of mnemonics.

(c) Instruments.
Gamelan are comprised of gongs, metallophones, xylophones, gong-chimes, drums, cymbals, flutes and spiked fiddles in various combinations (Table 2). Materials of construction include bronze, iron, wood and bamboo. Gongs range in size from small to very large. Most are hung vertically and struck with a padded mallet and provide a framework that marks the form. Others are held horizontally, are struck with a hard mallet and provide secondary punctuation or serve as a time-keeper. Metallophones are in pairs and consist of two types: with keys suspended over bamboo resonators (e.g. gender), and with keys resting on trough resonators (e.g. gangsa jongkok). Each metallophone in a pair is precisely tuned slightly apart from the other to produce acoustic ‘beats’. Gong-chime instruments consist of a row of graduated tuned kettles, which are played either as a solo melodic leading instrument or by several people playing interlocked figuration. Various non-pitched idiophones, such as ceng-ceng (cymbals, large or small) or gentorak (bell tree), complement ensembles. Suling (flutes) are played using circular breathing to produce a continuous sound; the rebab (bowed spike-fiddle) is played only in soft ensembles, with a technique that differs from that of Javanese rebab. Various sizes of two-headed drums (kendang) are played with and without mallets (see alsoGamelan, §I, 5(iv)).
Although there are many varieties of gamelan, most follow similar musical principles; discussion here will use gamelan gong (developed from gamelan gong gede and semar pagulingan) as a model.
