Stanislavsky Use of Improvisation is the first work that brings together material across Stanislavsky entire career to survey his use of improvisation. Improvisation was a key concern for Stanislavsky, one that impinged on his acting, directing, and pedagogical work. Consequently, it features in many books on the System, but this study is unique because it focuses explicitly on improvisation and its place in Stanislavsky development as a theatre-maker. This allows the reader to see how Stanislavsky treated improvisation as a highly mutable practice that was not bound to one particular interpretation, definition, or application. Improvisation will always relate to the present moment in an actor work, to the here and now; it values aliveness and an engagement with the role. Beyond that, however, Stanislavsky use of improvisation was a dynamic and expanded one that answered a range of work challenges.
