Jo Salas herself describes her book as follows: "This book describes a form of improvisation. It is based on stories of more or less everyday events that are told during a performance - dreams, memories, fantasies, tragedies, and farces: snapshots from the lives of real people. This improvisation is easily accessible and fun; it takes place in theaters, but also outside of them - in fact, it works in any setting. Whether practiced by seasoned actors or awkward beginners, playback theater honors individual experiences and the relationships between people - through their stories.".
