Improvise:

For more than 20 years of directing, teaching, and participating in improvisation, Mick Napier has watched thousands of scenes. His experience has led him to continually question why and how scenes work or don't work and what one must do in order for a scene to be successful. In this book, he takes an irreverent but constructive look at the art and practice of improvised scenes. He covers such topics as: two-person scenes; group scenes; entering scenes; techniques to achieve richer, more layered scenes; auditioning; solo exercises for practice at home. Napier also challenges the conventional wisdom of the rules of improvisation, examining what's behind them and how they came to be in the first place.
