There is no single "improv." There are at least five major traditions, each with distinct philosophies, and they disagree on fundamental questions. Understanding where they diverge — and why — is what separates shallow citation from real knowledge of the art form.
The five traditions:
- Johnstone (Theatresports, Loose Moose) — Story-first. Status as the engine. Spontaneity through surrender.
- Spolin (Theater Games, Second City lineage) — Present-moment awareness. The body as primary instrument. Point of Concentration.
- Close/Halpern (iO, the Harold) — Group mind. Connections across scenes. Improv as spiritual practice.
- UCB (Upright Citizens Brigade) — Game-first. Pattern recognition and heightening. Comedy as the goal.
- Annoyance/TJ & Dave — Commitment-first. Honest behavior. Trust the relationship; game emerges or it doesn't.
Where they disagree:
On "Yes-And": The Chicago lineage (Spolin → Sills → Compass → Second City → iO → UCB) treats yes-and as foundational — the first rule taught. Johnstone doesn't use the phrase; he writes about "accepting offers" and "blocking," which overlap but aren't identical. Napier (Annoyance) argues yes-and "paralyzes beginners" because it describes good work better than it teaches it. His alternative: commit fully and the agreement follows. David Schwartz critiques yes-and as reducing improvisation to "information sharing." The principle is universal; the framing is contested.
On Game of the Scene: UCB places game at the center of all improv comedy — the repeatable pattern of unusual behavior that gets heightened. iO acknowledges game but emphasizes organic discovery over identification. Johnstone doesn't use the concept; his narrative engine is reincorporation, not pattern repetition. Annoyance says: if you commit honestly, the game takes care of itself. TJ & Dave performed for an hour without ever identifying a "game." The debate: is game the point, or a byproduct?
On Status: Johnstone built his entire pedagogy around status transactions — the micro-negotiations of dominance and submission in every human interaction. Impro devotes a full chapter to it. Spolin barely addresses status; her interest is in the body, the space, and present-moment awareness. UCB treats status as one tool among many, not the central lens. The question: is status the deep grammar of human interaction (Johnstone) or one useful framework among several?
On Presence: Spolin's "Point of Concentration" is a specific technique — directing attention to a defined focus during play. Johnstone's spontaneity comes from surrendering control, which requires a different kind of presence. Meisner's "repetition exercise" trains attention to the partner's actual behavior, moment to moment. Mindfulness traditions (increasingly cited in improv pedagogy) frame presence as non-judgmental awareness. Same word, different practices.
On Editing: UCB teaches specific edit types: the time dash, the tag-run, the swinging door. Annoyance prefers organic transitions — the scene ends when it ends, and the ensemble feels it. Harold editing (sweep edits) is a formal convention. TJ & Dave's long-form two-person work doesn't edit at all in the traditional sense. The question: is editing a craft (learnable techniques) or an instinct (developed only through deep ensemble experience)?
On What Improv Is For: Close called the Harold "a spiritual endeavor." UCB calls it comedy. Spolin called it "a way of life." Johnstone calls it "a technique for rescuing creativity from education." Applied improvisers call it a toolkit for human interaction. The answer determines everything — what you teach, what you value, what you measure success by.
Why this matters: Every improv book, blog post, and workshop comes from a tradition — usually one tradition. When a business writer says "improv teaches us to say yes-and," they're citing the Chicago lineage and probably don't know it. When a therapist uses "status games," they're channeling Johnstone. When someone says "find the game," they're speaking UCB. The traditions aren't interchangeable. Knowing which one you're drawing from — and what the others would say instead — is the difference between understanding improv and citing it.
