Common Theater Terminology You’ll Hear in Rehearsals and During Shows

This chapter is a working vocabulary you can use immediately. Terms are grouped by when and where you’ll hear them: in rehearsal, while staging, in technical work, backstage, and during performances. For each term you’ll get a plain definition, a quick example, and a common confusion to avoid.

Rehearsal Terms (in the room with the director)

Beat

• Definition: A small unit of action or change inside a scene—often marked by a shift in intention, topic, emotion, or tactic.
• Example sentence: “Let’s take it from the top of the scene and find the beat where you realize you’ve been lied to.”
• Common confusion to avoid: A beat is not automatically a pause. You might pause on a beat, but the beat is the change, not the silence.

Objective

• Definition: What a character wants in the scene (or moment) that they can actively pursue.
• Example sentence: “Your objective here is to get them to stay—play it like you need an answer right now.”
• Common confusion to avoid: Don’t make it vague (“to be happy”) or passive (“to understand”). Make it playable (“to convince them,” “to get the truth,” “to win their trust”).

Notes

• Definition: Feedback given after a run or section of work—can be acting, pacing, clarity, safety, spacing, or consistency.
• Example sentence: “Notes: pick up the cue line faster, and don’t cross in front of the table on that moment.”
• Common confusion to avoid: Notes are not a debate during delivery. If something is unclear, ask a short clarifying question after the note is given.

Line run

• Definition: A rehearsal focused on speaking lines (often quickly) to lock in memorization and cues, usually with minimal movement.
• Example sentence: “We’ll do a line run of Act 1 tonight—keep it moving and don’t stop for acting choices.”
• Common confusion to avoid: A line run is not the same as a full run. The goal is accuracy and flow, not performance intensity.

Staging Terms (movement, facing, and what the audience sees)

Cheat out

• Definition: Adjust your body angle so the audience can see your face and important action, even while you’re talking to another character.
• Example sentence: “Cheat out on that whisper so we can see your reaction.”
• Common confusion to avoid: Cheating out doesn’t mean ignoring your scene partner. It’s a subtle angle shift, not turning your back on the relationship.

Upstage / Downstage

• Definition: Downstage is closer to the audience; upstage is farther from the audience.
• Example sentence: “After the reveal, step downstage center and hold for a moment.”
• Common confusion to avoid: Don’t map it to “north/south” in the building. It’s always based on the audience’s location for that production.

Sightline

• Definition: The line of vision from audience seats to the stage; if something is blocked by scenery or people, it’s “out of sightline.”
• Example sentence: “That reaction is great, but you’re behind the flat—your face is out of sightline.”
• Common confusion to avoid: “I can see it from the stage” doesn’t mean the audience can. Trust notes from the house (director/stage manager/designers).

Stage left / Stage right (perspective check)

• Definition: Directions are named from the performer’s perspective while facing the audience: stage left is the performer’s left; house left is the audience’s left.
• Example sentence: “Enter stage right and cross to the chair at stage left.”
• Common confusion to avoid: Mixing up stage vs. house directions is the #1 beginner mistake. A quick fix: stand facing the audience and physically point to your left/right.

Technical Terms (lights, sound, and repeatable setup)

Spike mark

• Definition: A small tape mark on the floor showing an exact position for an actor, prop, or piece of scenery.
• Example sentence: “Find your spike mark before the spotlight comes up.”
• Common confusion to avoid: Don’t move or peel spike tape without permission. If a mark is wrong or lifting, report it so it can be fixed consistently.

Gobo

• Definition: A metal or glass template placed in a lighting instrument to project a pattern (like window panes, leaves, or texture).
• Example sentence: “The gobo gives us a ‘streetlight through blinds’ look for the scene.”
• Common confusion to avoid: A gobo is not the light itself; it’s the pattern-maker inside/with the fixture.

Gain

• Definition: The input sensitivity/level on an audio device (mic pack, mixer channel, preamp) that affects how strong the signal is before overall volume.
• Example sentence: “Your mic is distorting—let’s lower the gain and then adjust the fader.”
• Common confusion to avoid: Gain is not the same as “turning it up.” Too much gain can cause distortion or feedback even if the speaker volume seems moderate.

Preset

• Definition: Items placed in their exact starting positions before a rehearsal or show (props, furniture, costumes, mic packs, etc.).
• Example sentence: “Check your presets: letters on the desk, coat on the hook, glass already filled.”
• Common confusion to avoid: A preset is not “somewhere nearby.” It’s a specific, repeatable location so the show can run the same way every time.

Backstage Terms (where you wait, move, and change)

Wings

• Definition: The offstage areas to the left and right of the stage where performers and crew wait to enter.
• Example sentence: “Stand by in the wings for your entrance—stay quiet and out of view.”
• Common confusion to avoid: Being “in the wings” doesn’t mean you’re invisible. You can still be seen if you’re too close to the edge or lit by spill light.

Crossover

• Definition: A backstage path that lets you move from one side of the stage to the other without being seen by the audience.
• Example sentence: “After you exit stage left, take the crossover to get to your next entrance on stage right.”
• Common confusion to avoid: Don’t assume the crossover is silent or clear. Move carefully—there may be cables, storage, or crew traffic.

Quick change

• Definition: A very fast costume change (sometimes with help) that happens in a short window between exits and entrances.
• Example sentence: “You have a 45-second quick change—go straight to the quick-change area and follow the order.”
• Common confusion to avoid: A quick change is a planned sequence, not improvisation. Don’t add extra items or change the order without checking, or you’ll lose time.

Performance Terms (during the show and audience-facing moments)

Hold

• Definition: A temporary stop or freeze in action, usually for safety or a technical issue; you stay in place and remain quiet until released.
• Example sentence: “Hold! We have a prop on the deck—everyone freeze.”
• Common confusion to avoid: A hold is not a chance to chat or reset yourself loudly. Stay in character position (unless safety requires moving) and wait for instructions.

Reset

• Definition: Returning props, costumes, scenery, and sometimes performers to their starting positions for the next run or the next show.
• Example sentence: “After the show, reset the table: two glasses, letter upstage right corner, chair angled out.”
• Common confusion to avoid: Reset is not “clean up later.” It’s specific and immediate so the next performance starts correctly.

Curtain call

• Definition: The bows at the end of the performance when performers acknowledge the audience’s applause.
• Example sentence: “Stay in order for curtain call—enter on your cue and hold your place.”
• Common confusion to avoid: Curtain call is not random wandering. Spacing and timing matter, and you should follow the planned order so everyone is seen safely and fairly.

Scenarios

• 1. You’re told to stand on a small tape “X” so the special light hits you exactly.
• 2. The director asks you to angle your shoulders so the audience can see your face during a conversation.
• 3. The group is going to speak through the scene quickly to check memorization and cue lines.
• 4. You’re waiting just offstage for your entrance, staying quiet and out of view.
• 5. You exit one side but need to appear from the other side without being seen crossing behind the set.
• 6. Before rehearsal starts, you place the letter, cup, and jacket in their exact starting locations.
• 7. You’re acting behind a tall piece of scenery and someone says the audience can’t see your reaction.
• 8. The sound operator adjusts the input level because your mic is distorting when you speak loudly.
• 9. Everything stops because something unsafe happened onstage, and you’re told to freeze.
• 10. At the end, you come out to bow in a planned order to acknowledge applause.

Optional step-by-step: How to self-check stage directions fast

1. Face the audience area (even if it’s empty).

2. Point to your left hand: that’s stage left.

3. Point to your right hand: that’s stage right.

4. Step one pace toward the audience: that’s moving downstage.
