This book will help the beginning singer understand the importance of correct breathing, resonance, range, posture and focus. The book is complete with diagrams, poster (which I liked enough to hang on the wall in my voice lesson studio), vocal exercises, descriptions and demonstration CD. It follows a clear path of development and I think most beginners will learn a lot from this book. I suspect that most beginning students will have difficulty mastering any of these concepts or exercises without the assistance of a voice teacher. A more advanced student would likely have already covered this material with their private voice teacher. I would recommend this book as a good source of fundamental knowledge for the beginning student.
