In this document, a description of the literature of non-idiomatic improvisation is provided.
An analogy with the established field of non-idiomatic improvised music is continuously
employed to define a literary counterpart. Elements of both the non-idiomatic nature and the
improvisational nature of literature are identified. Five works of fiction by established authors
are evaluated in terms of these criteria. Finally, one work of fiction by an author who identifies
himself as a writer of non-idiomatic improvised literature is discussed.
