Book excerpt: Within the body lie all the elements (anatomy, physiology and the connection between the mind and body) which are needed to produce sound. Every instrument has a frame. The unique thing about the human vocal instrument is that the body skeleton is the frame. The purpose of this book is to help the voice professional understand this instrument and know how to take care of it. This book defines common problems and discusses how to fix these problems based on the specialization of the voice professional.
