Blocked Vs. Unblocked Scenes
Blocked Vs. Unblocked Scenes is a comparative exercise in which performers play the same scene twice: once using denial and blocking, and once fully accepting every offer. The side-by-side contrast vividly demonstrates how blocking kills momentum while acceptance generates possibilities. It is one of the most effective tools for teaching the principle of agreement.
Structure
Setup
Two performers. The facilitator gives them a simple, concrete scene premise: a job interview, a first date, two neighbors arguing over a fence, a patient visiting a doctor.
Round 1: The Blocked Scene
Players perform the scene using denial, blocking, and redirection. Every offer is rejected, changed, or ignored. If one player says "I'm so glad you came to my birthday party," the other says "This isn't a birthday party." If someone establishes an object, the partner pretends it isn't there. The scene quickly becomes incoherent and stalled.
Run for 60-90 seconds - enough to feel the full effect without torturing the audience.
Round 2: The Unblocked Scene
Same premise. Same starting point. This time, players accept every offer fully and build on it. The birthday party is real - and there's a surprise. The object exists and becomes important. The relationship that was established gets deepened.
Run for 90-120 seconds.
Group Discussion
Pause between rounds 1 and 2 to ask: "What happened? What did you notice?" Then run round 2 and repeat the question.
Variation: Role Reversal
The players who watched now perform the same two rounds. New premise. Same structure.
How to Teach It
How to Explain It
"We're going to play the same scene twice. First: try to block everything your partner offers. Say no. Change what they establish. Second time: yes-and everything. Same starting point. Watch what happens."
Why It Matters
Blocked Vs. Unblocked Scenes is among the most pedagogically direct exercises in the improv training canon. The side-by-side format makes the contrast between blocking and acceptance impossible to argue with. Players who intellectually understand "yes-and" but haven't felt its effects in the body often experience a genuine revelation in this exercise. The unblocked scene invariably generates more narrative momentum, richer characters, and more genuine emotion - not because the performers are trying harder, but because the acceptance creates conditions for creativity to emerge.
Common Coaching Notes
- Brief the blockers clearly. Performers sometimes soften the blocking because they feel rude. Encourage them: "Be a genuine blocker. That's the whole point of round one."
- Don't let round 1 run too long. 60-90 seconds of blocking is enough to feel the effect. Beyond that, it just becomes unpleasant.
- The reveal conversation is essential. Don't skip the mid-exercise discussion. Ask the performers: "How did it feel to block? How did it feel to accept?" The subjective experience is as important as the observable result.
- Use with resistant performers. Players who intellectually resist the "yes-and" principle often shift after experiencing this exercise. It's evidence, not argument.
- Connect to specific scene moments. After the exercise, watch a scene the group performs and note moments where blocking appears. Having a shared reference makes feedback much more specific.
Debrief Questions
- What happened narratively in each version?
- How did it feel in your body to block? To accept?
- What made the unblocked scene work even when it went somewhere surprising?

Related Exercises
I Know
I Know is a scene-building exercise in which performers respond to every offer with the two-word affirmation that names the game, followed by an addition that expands the shared reality. The response functions as an amplified form of yes-and: it validates the partner's offer, implies pre-existing shared knowledge, and propels the scene forward through rapid mutual agreement. The exercise prevents denial and forces each player to build on their partner's contributions without hesitation, creating scenes that accumulate detail and emotional weight at speed.
Agreement Scenes
Agreement Scenes is an exercise in which performers practice fully agreeing with every offer their scene partner makes. By removing all conflict and negation, the exercise reveals how scenes can build through mutual enthusiasm and escalating shared reality. It reinforces the "yes, and" principle at its most fundamental level.
What?
What? is an exercise in which performers respond to each offer with genuine curiosity, exploring rather than accepting at face value. The exercise teaches the difference between blocking and curious investigation, building the habit of digging deeper into a partner's offers.
Three Rules
Three Rules is a scene exercise in which the facilitator establishes three specific constraints that performers must maintain throughout their scene. The constraints can be physical (always touching the wall, never letting your hands go below your waist), verbal (never using the letter S, only asking questions), or behavioral (treat your partner as royalty, move as if underwater). The exercise demonstrates that limitations generate rather than restrict creative choices, and trains performers to divide attention between scene work and rule compliance.
Yes And
Yes And is the foundational improv exercise and philosophical principle in which performers practice accepting a partner's offer (the "yes") and adding new information that builds on it (the "and"). One player makes a statement; the partner responds by first affirming the reality of that statement and then contributing something new. The exercise trains the most essential skill in improvisation and has become the defining principle of the entire art form.
Opposites
Opposites is an exercise in which two performers play a scene while deliberately making contrasting choices in energy, physicality, and emotional tone. If one player is loud, the other is quiet; if one is deliberate, the other is impulsive; if one is formal, the other is casual. The exercise teaches the dramatic value of contrast and develops awareness of how opposing choices create dynamic scenes and interesting characters.
