I was just there for a week, heard bith gamelan and a cappella chants (kecak mostly) and was interested to find out from wikipedia that often gamelans even in adjacent villages will have different tunings, and sometimes a large gamelan will have dual sets of instruments for the two most popular scales. A decent approximation is a set of 7 tones selected from 9-tone equal temperament, and from those seven, different sets of 5-tones scales...
