A brief background history of Balinese music in its regional context is followed by an introduction to gamelan instruments, an explanation of the basics of gamelan music, and a working through in some detail of the music for the first part of the Baris dance. The emphasis in this is on gong kebyar, but a broader survey follows, encompassing bamboo, sacred, and lesser-known ensembles. There's also a brief account of the place of music in Balinese society, given life by biographies of three musicians from different generations.
Tenzer himself is a composer and performer as well as a scholar, and conveys a feel for what is very much a live tradition. He includes some advice on getting involved with Balinese music, both in Bali and abroad. And a final chapter, added in this 2011 third edition, covers the last twenty years. (The work was originally published in 1991 and earlier editions had the shorter title Balinese Music.)
