There are about 6,000 inhabited Indonesian islands and, as you can probably guess, there may be 6,000 different kinds of Indonesian music. Some Indonesian music is highly-pattered and meticulously structured, some is loose and sprawling. Some Indonesian music is firmly rooted in ancient tradition, some is ardently modern. Some Indonesian music is Islamic, some Christian, some secular, some all of the above. Look for almost anything in Indonesian music and you’ll find it. If you want to find an Indonesian music starter set, a good instinct would be to look for a compilation that provides a broad introduction to the most important Indonesian musical styles. Throughout the 1990s, Smithsonian Folkways collaborated with the Society for Indonesian Arts on exactly that kind of compilation.
