Gambang


A gambang, properly called a gambang kayu ('wooden gambang') is a xylophone-like instrument used among peoples of Indonesia and the southern Philippines in gamelan and kulintang, with wooden bars as opposed to the metallic ones of the more typical metallophones in a gamelan. A largely obsolete instrument, the gambang gangsa, is a similar instrument made with metal bars.

The bars of the instrument are made of a se wood, generally teak. It also found in ironwood (kayu besi). The bars mounted in a deep wooden case that serves as a resonator. Instruments typically have 17-21 keys that are easily removed, and are kept in place by having a hole through which a nail is placed. Generally a full gamelan has two sets, one gambang pelog and the other one gambang slendro.

A pair of long thin mallets (tabuh), made of flexible water buffalo horn tipped with felt, are used to play the instrument. Gambangs are generally played in parallel octaves (gembyang). Occasionally, other styles of playing are employed such as playing kempyung which are playing two notes separated by two keys. Unlike most other gamelan instruments, no dampening is required, as the wood does not ring like the metal keys of other instruments.

The gambang is used in a number of gamelan ensembles. It is most notable in the Balinese gamelan Gambang. In Javanese wayang, it is used by itself to accompany the dalang in certain chants. Within a full gamelan, it stands out somewhat because of the high speed of playing, and contrasting timbre because of its materials and more because it has a wider melodic range than the other instruments.

In Javanese gamelan, the gambang plays cengkok like the other elaborating instruments. However, the repertoire of cengkok for the gambang is more rudimentary than for other instruments (for instance, the gendér), and a great deal of variation is accepted.
