Group Improvisation

The Manual of Ensemble Improv Games

By Peter Campbell Gwinn; Charna Halpern
2003

Group Improvisation: The Manual of Ensemble Improv Games, by Peter Campbell Gwinn and Charna Halpern, is a comprehensive and highly practical resource for anyone looking to master the elusive concept of 'the Group Mind.' Published in 2003, the book distills the foundational training methods of the iO Theater (formerly ImprovOlympic) into a series of over forty games designed specifically to move a group of individuals from 'selfish performing' to 'collaborative creation.'

The work is built on the belief that the strongest improv happens when the ensemble ceases to act as a collection of roles and starts to act as a single, unified entity. Gwinn and Halpern provide a categorized library of games that build the 'muscles' of the group mind: including concentration, support, listening, and pattern recognition. The book is particularly noted for its focus on 'The Harold,' providing a series of 'component games' that train the performers in the specific skills needed for each section of the classic long-form structure. Each exercise is accompanied by a 'Coaching Tips' section that helps the facilitator identify the 'blocks' and 'shortcuts' that often plague a developing troupe.

The text is written in a direct and encouraging voice, filled with anecdotes from the rich history of the Chicago improv scene. It emphasize that 'Group Mind' is not a mystical state of being but is the result of rigorous practice and a deep commitment to making one's partner look good. Group Improvisation serves as an essential companion for any improv coach or performer looking to build a more connected, resilient, and creatively explosive ensemble.
