A Monoscene is an improv form that takes place in a single location in a single span of time, with no external edits of any kind.
The term monoscene was first used to describe a form used by the Swarm in the original version of Slow Waltz Around Rage Mountain at UCBT in NY. It was a single long scene in the same space and time, like an act of a play with no blackouts. Internally it worked more like a Harold, however. Instead of external edits, the scenes would be edited by a character entering or exiting. Like multiple beats of a Harold, characters would return multiple times. It had roots in several shows and forms, some in Chicago and some in NY such as Close Quarters, Naked, Möbius American Theatre, Tracers and Individually Wrapped, all of which featured extended scenes with entrances and exits rather than many smaller scenes which jumped from place to place. It's not meant to be one long group scene, although sometimes shows like that are termed monoscenes.
60 minutes, 2 improvisors, 1 scene. This show was performed at iO Theater in Chicago. It starred Stephnie Weir and Jimmy Carrane. It was directed by Rob Mello. Kevin Mullaney produced the show and was the assistant director.
