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.

The Harold
The Harold is the foundational long-form improv structure, serving as the "Latin" of the art form. Developed by **Del Close** and popularized through **The Committee** in San Francisco and later **iO Chicago**, it is a complex, collage-like structure that uses a single suggestion to build a series of interconnected scenes, group games, and thematic explorations. According to the *Upright Citizens Brigade Comedy Improvisation Manual*, the Harold is not just a format but a training tool that teaches improvisers how to listen, find patterns, and connect disparate ideas into a unified whole. It is characterized by its three-beat structure, where three distinct storylines are established, heightened, and eventually merged. It represents the transition of improv from short-form games into a cohesive, long-form theatrical piece, demanding a high level of "group mind" and thematic awareness from its players. The Harold is often described as a "symphony" of improv, where individual melodies (scenes) are woven into a complex, thematic tapestry.
French Harold
French Harold is a long-form format variant of the Harold, developed within European improv traditions and distinguished by a structural emphasis on imagery, poetic logic, and the thematic monologue opening rather than a suggestion-driven audience call. The format preserves the Harold's three-beat, three-group architecture but tends toward more abstract, metaphor-rich scene work and a slower, more contemplative pacing than the North American Harold tradition.
Deconstruction
The Deconstruction is a long-form improv format that takes a single opening scene and systematically revisits its elements from different angles, time periods, perspectives, or contexts. Each subsequent scene deconstructs an aspect of the original, exploring a character's backstory, a theme's implications, or a relationship's origin. The format demands structural thinking, the ability to identify multiple entry points within a single premise, and the ensemble skill of building an interconnected web of scenes that deepen the audience's understanding of the original material. The Deconstruction rewards analytical improvisers who can identify the richest elements of a scene and expand them into full explorations.
