Singing involves the correct co-ordination of the whole body. This book explains the mechanisms involved by presenting the anatomical, physiological and phonological data relevant to voice production. Scientific data and explanations are presented alongside teaching instructions, so that they can be linked to familiar experiences to the singer. The book is addressed to the singer, to teachers and students of singing and to anyone of the medical profession dealing with vocal disorders. No prior knowledge is needed. It can be used either for individual study or in lessons. A useful index is included.
