The Gamelan: An Orchestra Tuned as One Set
In parts of Indonesia, especially on the islands of Java and Bali, music is often played by a gamelan. This is an orchestra made mostly of percussion instruments, such as gongs, drums, and rows of metal bars that are struck with mallets. The sound is shimmering, layered, and full of ringing tones.
A gamelan is different from an orchestra of violins and trumpets in one way. Its instruments are made and tuned together as a single set. A violin from one maker can usually play with a violin from another. But a gong from one gamelan may not match another gamelan, because each set has its own tuning. So the instruments in a set belong together, and many gamelans have their own names.
Players often sit on the floor, each one close to an instrument. No one person leads with a baton like a conductor. Often a drummer gives signals that tell everyone when to speed up, slow down, or end. Big hanging gongs mark the ends of long musical phrases, like the punctuation at the end of a sentence.
A gamelan may play for a village celebration, for a dance, or for a shadow puppet show. The players listen closely to one another, because the music is made by the whole group working in step.
