Editing Improvisational theatre (section)

==Non-comedic, experimental, and dramatic, narrative-based improvisational theater==
Other forms of improvisational theatre training and performance techniques are [[Experimental theatre|experimental]] and avant-garde<ref>Experimental Theatre from Stanislavsky to Peter Brook by James Roose Evans</ref> in nature and not necessarily intended to be [[comedy|comedic]]. These include [[Playback Theatre]] and [[Theatre of the Oppressed]], the [[Jerzy Grotowski|Poor Theatre]], [[the Open Theatre]], to name only a few.

[[The Open Theatre]] was founded in New York City by a group of former students of acting teacher [[Nola Chilton]], and joined shortly thereafter by director [[Joseph Chaikin]], formerly of [[The Living Theatre]], and Peter Feldman. This avant-garde theatre group explored political, artistic, and social issues. The company, developing work through an improvisational process drawn from Chilton and [[Viola Spolin]], created well-known exercises, such as "sound and movement" and "transformations", and originated radical forms and techniques that anticipated or were contemporaneous with [[Jerzy Grotowski]]'s "[[poor theater]]" in Poland.{{citation needed|date=May 2021}} During the sixties, Chaikin and the Open Theatre developed full theatrical productions with nothing but the actors, a few chairs, and a bare stage, creating character, time, and place through a series of transformations the actors physicalized and discovered through improvisations.

On the west coast, [[Action Theatre (Ruth Zaporah)|Ruth Zaporah]] developed [[Action Theatre (Ruth Zaporah)|Action Theatre]], a physically based improvisation form that treats language, movement and voice equally. Action Theatre performances have no scripts, no preplanned ideas and create full-length shows or shorter performances.  Longform, dramatic, and narrative-based improvisation is well-established on the west coast with companies such as San Francisco's [[BATS Improv]]. This format allows for full-length plays and musicals to be created improvisationally.
