Preface book will necessarily mainly discuss the outside manifestations of Baduy life and music and the Baduy's struggle with the many temptations leading them away from their ascetic path. I hope it does not reveal anything that should have remained secret.All photographs were taken by the author, unless stated otherwise, and are published with permission. The subtitle of this book, 'Singing is a medicine' , was taken from the beginning of the Lutung Kasarung pantun story recited by Sajin and recorded in January 1977: '… Singing is a medicine to calm down …' The audio-visual examples are based on field recordings by the author. All recordings were made with prior informed consent of the individual musicians and the Baduy leaders. Mostly the participating musicians were paid a lump sum for their performance. At rituals recordings were generally not allowed. If allowed, contributions were made in cash for food, sweets and cigarettes. The audiovisual examples supply part of the Baduy soundscape and were also used for the transcription and/ or analysis of the music. Some music examples were not included after consultation with the Baduy leaders. They apparently found that these examples disclosed too much of their ascetic life and should not be shown to the general public with limited knowledge of Baduy life (see Section 3.3).I am grateful for the stimulating discussions with teachers, colleagues and pupils about Baduy issues. First of all there was Bishop Geise, who wrote a pioneering book on the Baduy in 1952; he granted me an interview in Bandung in November 1976. At an early stage, July 1978, I also had the fortune of meeting Anis Djatisunda in Sukabumi for an interview on the Baduy. Further, I appreciate Yudistira Garna's trust in me: in October 1992 he gave me permission to copy his 1988 (unpublished) anthropological PhD dissertation on the Baduy. This book is still a very important source of information.In later years I enjoyed discussions about Baduy and Sundanese performing arts with Randal Baier, Sarah Andrieu, Dody Satya Ekagustdiman and many others. In the Netherlands there have been several anthropologists who stimulated me by their own research on the Baduy: Jet Bakels, Wim Boevink, Gerard Persoon, Bart Barendregt and Robert Wessing. Clara Brakel shares my interest in the performing arts of Indonesia and her suggestions were always useful for my work on the Baduy. Both anonymous reviewers of an earlier version of this book were very helpful with their encouraging and critical remarks.My wife Ellen assisted me on the first two fieldwork trips to the Baduy in 1976. Also, she has been very supportive during the long period of writing this book.
