How to Improvise a Full-Length Play
The Art of Spontaneous Theater
Kenn Adams' How to Improvise a Full-Length Play: The Art of Spontaneous Theater is a groundbreaking guide for improvisers who want to move beyond the 'sketch-based' model of the Harold to create cohesive, ninety-minute unscripted theatrical works. Published in 2011, the book reflects Adams' experience as the founder of the Synergy Theater and his development of the 'Story Spine' and other structural tools that have since become foundational in narrative improv pedagogy.
The central premise of the work is that improvisation is not just for comedy: it is for theater. Adams provides a rigorous framework for sustaining narrative arc, character development, and thematic depth over a longer duration. He introduces the concept of 'Narrative Platforms' and 'Plot Tilts' as tools for the ensemble to coordinate their storytelling without a script. The book is particularly noted for its focus on 'The Story Spine': a eight-point structural model (Once upon a time... And every day... Until one day... Because of that... etc.) that helps performers maintain the 'engine' of the story regardless of the genre.
The text is structured as a technical manual, with exercises and strategies for every stage of the creative process: from 'world building' in the first act to the 'reversal and resolution' of the third act. Adams look at the unique demands of different genres: including 'The Improvised Shakespeare,' 'The Improvised Musical,' and 'The Improvised Film Noir': provide a 'generic blueprint' for each. How to Improvise a Full-Length Play serve as a vital guide for any troupe looking to master the structural and emotional complexities of unscripted narrative mastery.
