This book is a wide-ranging study of the varieties of gamelan music in contemporary Java seen from a regional perspective. While the focus of most studies of Javanese music has been limited to the court-derived music of Surakarta and Yogyakarta, Sutton goes beyond them to consider also gamelan music of Banyumas, Semarang and east Java as separate regional traditions with distinctive repertoires, styles and techniques of performance and conceptions about music. Sutton's description of these traditions, illustrated with numerous musical examples in Javanese cipher notation, is based on extensive field experience in these areas and is informed by the criteria that Javanese musicians judge to be most important in distinguishing them.
