Impro

Impro: Improvisation and the Theatre by Keith Johnstone

This book is about education as much as it is improvisation. In improvising, you must be willing to think on your feet and take risks. Getting somebody in the condition to do that requires work. At times, you need to be able to "roll with it" to keep some situation going, rather then shift elsewhere. It is also valuable to "think different". You may have difficulty coming up with a situation on the fly. However, thinking of it a different way makes it easy to come up with something.
