A practical investigation of how comedy works, by a well-respected practitioner and teacher.Comedy is recognised as one of the most problematic areas of performances. For that reason, it is rarely written about in any systematic way. John Wright, founder of Trestle Theatre and Told by an Idiot, brings a wide range of experience of physical comedy to this unique exploration of comedy and comedic techniques.The book opens with an analysis of the different kinds of laughter that can be provoked by performance. This is followed by the main part of the book: games and exercises devised to demonstrate and investigate the whole range of comic possibilities open to a performer.Why Is That So Funny? will be invaluable to teachers and performers and fascinating for anyone interested in how comedy works.
