Resonance in Singing and Speaking

Resonance in Singing and Speaking by Thomas Fillebrown, M.D., D.M.D. is a scientific and practical guide to the vocal mechanism, designed for singers, speakers, vocal coaches, educators, and students of voice. Drawing upon his dual expertise in medicine and vocal pedagogy, Dr. Fillebrown presents a clear and methodical explanation of how sound is produced, modified, and projected through proper vocal resonance. The book explores the anatomy of the vocal instrument, breath control, vocal registers, and the vital role of head and nasal cavities in achieving desirable vocal tone. Fillebrown also emphasizes the mental and psychological aspects of vocal development—highlighting the link between physical technique and emotional expression. Special focus is placed on correcting throat stiffness and improper voice placement—common issues among both beginners and professionals. Complete with practical breathing exercises and a scientifically grounded yet accessible style, this book is not only an instructional manual but also a foundational text on the art and science of healthy, resonant vocal production. Whether for public speakers, singers, or speech therapists, this work remains a timeless resource in vocal training literature.
