With the "talking cure", Freud showed how many ailments can be identified and healed through dialogue. But the most immediate vocal expression of feeling comes through song. In this reappraisal of the healing power of sound, Paul Newham discusses the origins of voice, music and language, the discoveries of 20th-century therapists, and the remarkable voice of modern theatre directors. He goes on to explain the scientific principles of vocal sound and to show how this can be combined with traditional analysis to release suppressed feelings and tensions. The author presents several case studies to demonstrate the effectiveness of voice therapy.
