I wish to thank Michelle MacAleese and Valerie Joy Turner for their patient editing and guidance with this rather difficult and long book. I also wish to thank Dr. Lynette Harper (Vancouver Island University) and Meiver de la Cruz (Visiting Assistant Professor of Dance at Oberlin College) for their useful comments on the dance chapter. I also thank my wife, Suzanne Meyers Sawa, for her support and advice throughout this whole project. I wish to express my eternal gratitude to Dr. Eckhard Neubauer (Institute for the History of Arabic-Islamic Science at the Goethe University, Frankfurt) for his generous spirit and for his advice over the years about musicological and socio-cultural issues.
