This book is a collection of my articles published in English, French and German between 1977 and 2000. Translations of my articles originally published in Japanese are not included here. All writings are reproduced keeping their original forms with an exception: 1997a "Revitalisation of East Asian court music traditions in global networks: reputare nihil insulatum (consider nothing isolated)". Places of their first publication are indicated in my comment to the respective writings. I acknowledge with gratitude the publishers who have granted permission to reprint my writings.
