This new and updated edition of Voice: Onstage and Off is a comprehensive guide to the process of building, mastering, and fine-tuning the voice for performance. Revised with the contemporary actor in mind, this fourth edition empowers actors wishing to master their voice as performers. Every aspect of vocal work is covered, from the initial speech impulse and the creation of sound, right through to refining the final product in different types of performance. Tackling emerging discussions at the intersections of voice and identity, with new content dedicated to voice for trans and non-binary actors, as well as introducing students and practitioners to the anatomical aspects of voice and to auditory awareness, the book equips actors to hone, care for, and define their voice. Among other new features in this fourth edition are coverage of transgender acting and heightened auditory awareness, which bring this established textbook to a modern audience. This highly adaptable course of study empowers performers of all levels to combine and evolve their onstage and offstage voices. Online resources are available for each chapter, including audio examples, additional exercises, and content for instructors.
