Resonance in singing and speaking

Resonance in Singing and Speaking is a classic voice instruction guide by Thomas Fillebrown. Efforts to develop my own voice and the voices of my patients after operations for cleft palate, aided by anatomical study, resulted in a plan for the focusing and development of the human voice quite different from any other yet published or, so far as I know, yet proposed. This plan has proved so successful in my later life that I feel emboldened to offer it as a voice guide for the consideration of speakers and singers.
