Study the list of gamelan instruments in WOM, pp. 219 and their accompanying illustrations in Fig. 7-2. p. 218. What four categories of instruments are usually found in gamelan ensembles?

What will be an ideal response?

• knobbed gong instruments
• metal keyed instruments (metallophones)
• other melodic instruments
• drums

—The instruments described on WOM p. 217 represent two of the four categories of instruments in a typical gamelan ensemble.
• I. Knobbed Gong Instruments: gong ageng, gong siyem, kempul, kenong, kethuk, kempyang, bonang barung, bonang panerus.
• II. Metal Keyed Instruments (Metallophones) saron demung, saron barung, saron peking, gendèr slenthem, gendèr barung, gendèr panerus.

—Describe in detail, using WOM, one of the specific instruments in each category.
• Example I. The kenong is the "largest of the kettle gongs, resting horizontally in a wooden frame; from two to twelve per gamelan; played with a padded stick beater."
• The kenong is an idiophone—the instrument itself is the source of vibration.
• Example II. The saron and slenthem are "instruments with six or seven keys, which play the main melody."
