The Third Space serves a crucial need for contemporary performers by providing an interdisciplinary and physiovocal approach to training. It is a new take on body and voice integration designed to develop the holistic performer. It takes performers through a series of step-by-step practical physiovocal exercises that connects the actor's centre to the outside world, which increases awareness of self and space. It also develops a deeper connection between spaces within the body and the environment by connecting sound, imagination, and movement.

Robert Lewis's approach is a way of working that unlocks the imagination as well as connecting performers to self, space, and imagination, through voice and body. It conditions, controls, and engages performers by integrating various voice and movement practices.

The theories and practice are balanced throughout by:

introducing the practical works theoretical underpinnings through research, related work, and case studies of performances; demonstrating a full program of exercises that helps performers get in touch with their centre, their space, and shape both within and outside the body; and exploring the performers physiovocal instrument and its connection with imagination, energies, and dynamics.

This book is the result of nearly 20 years of research and practice working with voice and movement practitioners across the globe to develop training that produces performers that are physiovocally ready to work in theatre, screen, and emergent technologies.
