Blind Harold
Blind Harold is a long-form format that follows the Harold structure but removes one or more elements of awareness from the performers. Players may not know the suggestion, cannot see edits, or are otherwise denied information they would normally use. The format tests how deeply ensemble instincts can carry a show when conscious planning is stripped away.

Free-Form Improv
Free-Form Improv is a long-form approach in which performers follow no predetermined format or structure, allowing scenes, characters, and themes to emerge and connect organically. The absence of structural rules places maximum demand on ensemble instinct and editorial judgment. It is both the simplest and most demanding form of improvised performance.
Postmodern Musical
Postmodern Musical is a long-form musical format that deconstructs traditional musical theatre conventions through improvisation. Performers create an original musical in real time, often incorporating meta-theatrical commentary, non-linear storytelling, or genre subversion. The format demands strong musical improv skills and an awareness of the tropes being played with.
Monoscene
Monoscene is a long-form format in which the entire performance takes place in a single location in continuous real time. All entrances, exits, and events occur naturally within the established space, and the cast discovers relationships and storylines as they unfold. The format demands patience, strong listening, and the ability to build a rich world without the reset of scene edits.
Standard Musical
Standard Musical is a long-form format in which the ensemble improvises a complete musical in the style of a traditional Broadway show, with an original plot, characters, and songs created in the moment. The format follows conventional musical theatre structure with an opening number, ensemble scenes, solos, and a finale. It demands strong musical improv skills and narrative tracking.
Montage
Montage is a long-form improvised format in which performers present a series of thematically connected scenes inspired by a single audience suggestion. Scenes are linked by shared ideas, recurring motifs, emotional resonances, or occasional character callbacks rather than a continuous plot. The format's strength is its flexibility: any scene can follow any scene as long as the thematic connection holds. Montage is one of the foundational structures in Chicago-tradition long-form improvisation and is among the most widely performed long-form formats worldwide.
Micetro
Micetro is a competitive long-form format created by Keith Johnstone. A large cast of improvisers performs scenes that are scored by the audience, and the lowest-scoring performers are progressively eliminated until a single winner remains. The format combines the spontaneity of improvisation with the tension of a tournament structure.
