Music continues to be immensely influential in key developments of theatrical practices. In this study of musicality in the theatre, David Roesner offers a revised view of the nature of the relationship between music and theatre. The theoretical scope of the book is developed from a wide range of case studies, some of which are re-readings of the classics of theatre history (Appia, Meyerhold, Artaud, Beckett), while others introduce or rediscover less-discussed practitioners such as Joe Chaikin, Thomas Bernhard, Elfriede Jelinek, Michael Thalheimer and Karin Beier.
