This is a complete guide to sound in the theatre-kinds of sound systems and how they work for theatres large and small. John A. Leonard, formerly Head for Sound for the Royal Shakespeare Company, explains everything you need to know about sound design, from the basics to advanced work. Drawing upon his extensive experience with such RSC productions as Nicholas Nickelby as well as work with Stephen Sondheim, he explains the practical considerations in making theatre sound work. Theatre Sound includes a brief history of the use of sound in the theatre, discussions of musicals, sound effects, and the recording studio, and even an introduction to the physics and math of sound design. A bibliography and online reference section make this the new essential work for students of theatre and practicing sound designers.
