All professional voice users--whether singers and actors, teachers, lawyers, sports coaches, television hosts, salesmen, or business executives--depend on their voices in their profession. Often, the circumstances of voice use are not ideal, and difficulties can develop. This book is an informational source for professional voice users on how to care for and maintain the longevity of their voice. The authors are doctors and nurses whose medical practices specialize in the care of voice professionals. This is not a book on vocal pedagogy or training, but rather a guide to common medical problems that can affect the voice and to common vocal difficulties that can develop from ineffective voice use. This book is purposely designed to be easy-to-read, with multiple illustrations and photographs, and is intended for non-medical voice professionals. Those studying vocal performance, public speaking, and acting, as well as singing teachers, acting voice teachers, and voice coaches will find this material particularly useful, but it applies equally well to all voice professionals who use their voice in their livelihood. Printed in full color, with 64 high-quality illustrations and photos, including anatomical images.
