This international collection examines the opportunities for using music-induced states of altered consciousness to promote physical and mental healing, treat substance dependence, and in spiritual and palliative care. The contributors describe the successful use of altered states and their therapeutic potential, providing examples from different cultures and clinical, therapeutic and spiritual settings. Their observations cover a wide range of music types capable of inducing altered states, including polyrhythmic music, monotonous drumming, Western pop, and Arab musical schemata, complemented by theoretical and clinical approaches to applications in music therapy. This book will be a useful reference for practising music therapists, musicologists, and ethnomusicologists, students and academics in the field.
