Instruments of a gamelan orchestraA complete orchestra could have about 40 or more different instruments. There would be instruments that are struck to produce sound, such as kettledrums, xylophones, and gongs of various sizes. There would be a wind instrument, a bamboo flute called a suling, and string instruments such as a zither or lute. There would be instruments whose sounds are produced by vibration, such as drums, bells, cymbals and gongs.
There are also two sets of instruments that are tonal: the slendro tuned to five tones and the pelog, tuned to seven tones. The slendro is used to suggest festivity or cheerfulness, and is believed to have developed in Java in the eighth century. The pelog is used to express sadness, and is also very ancient in its origins. These two cannot be played together, but are used according to the mood of the piece being played.
