Voice production in singing and speaking, based on scientific principles

This work brings together the anatomy, physiology, and mechanics of the human voice with the practical needs of singers and speakers. Drawing on careful laboratory observations, it explains how the vocal folds, respiratory system, and surrounding muscles interact to produce sound, and why subtle changes in tension or airflow affect tone and clarity. The author emphasizes a scientific approach, arguing that reliable vocal training should rest on demonstrable facts rather than tradition alone.

Richly detailed illustrations accompany the text, from vivid laryngoscopic images of inflamed vocal cords to diagrams of chest movement during breathing. A new chapter expands the discussion to include the latest research and even touches on the psychological factors that influence vocal performance. Readers will find clear explanations that link theory to everyday practice, making the book a valuable reference for anyone seeking a solid foundation for healthy, expressive voice use.
