Given circumstances

The facts of a play's world - time, place, era, social setting, and prior events - that an actor uses to justify a character's behavior and choices. They come from the script itself and from careful inference beyond the dialogue.

Related: Magic if, Objective
Objective

A character's active want in a scene, phrased as a verb-directed action toward another person. Actors play objectives rather than emotions, and objectives shift as obstacles appear or tactics succeed or fail.

Related: Tactic, Obstacle
Tactic

The specific strategy a character uses to pursue an objective in the moment, such as pleading, threatening, or charming. Actors vary tactics to keep a scene alive and responsive to the other character's reactions.

Related: Objective, Obstacle
Obstacle

Whatever prevents a character from achieving an objective - another person's resistance, physical conditions, internal conflict, or social pressure. Strong obstacles create dramatic tension and give actors something concrete to play against.

Related: Objective, Tactic
Magic if

A rehearsal device asking an actor to imagine what they would do if the play's circumstances were real. It bridges the actor's own impulses and the fictional situation, supporting truthful behavior without literal belief.

Related: Given circumstances, Emotional recall
Emotional recall

An actor's technique of drawing on a remembered personal experience to access feelings similar to the character's. Useful for depth but risky if it substitutes for playing the scene's action and interactions.

Related: Magic if, Given circumstances
Beat

A small unit of dramatic action in which a character pursues one objective until something changes. Directors and actors break scenes into beats to shape pacing, clarify intentions, and mark shifts in relationship or power.

Related: Objective, French scene
Blocking

The planned movement and stage positions of actors, set by the director during rehearsal. Good blocking clarifies relationships, focuses attention, and keeps sightlines open for the audience.

Related: Stage picture, Cheat out
Stage picture

The visual composition formed by actors' bodies, levels, and spacing at a given moment. Directors use it to communicate status, relationships, and focus, and it changes continuously as blocking develops.

Related: Blocking, Levels
Cheat out

To angle the body or face partly toward the audience while appearing to address a scene partner upstage or to the side. It preserves the illusion of natural interaction while keeping the actor's expression visible.

Related: Blocking, Open up
Open up

Turning or repositioning so the audience can see an actor's face and body, often when a scene partner is upstage. It is a practical adjustment that serves visibility without visibly breaking the scene's logic.

Related: Cheat out, Blocking
Levels

Variation in height among actors created by standing, sitting, kneeling, or using platforms. Levels add visual interest, express status differences, and help the audience read relationships in a scene.

Related: Stage picture, Blocking
Cold reading

Performing a script aloud with little or no preparation, often at auditions. It tests an actor's ability to make quick choices, take adjustments, and connect with text and scene partners under pressure.

Related: Callback, Sides
Callback

A second or later audition to which selected actors are invited. Callbacks usually involve reading with other candidates, taking direction, or performing combinations, letting the creative team assess fit and flexibility.

Related: Cold reading, Sides

Short excerpts from a script used at auditions in place of the full play. Sides give the creative team a focused sample of an actor's work and often include brief context for the scene.

Related: Cold reading, Callback

Related: Catharsis, Peripeteia

A performance approach associated with Brecht that uses narration, signs, song, and visible stagecraft to keep spectators thinking critically rather than absorbed in illusion. It favors distance and social analysis over emotional identification.

Related: Alienation effect, Presentational acting

A style in which performers behave as if unaware of the audience, sustaining an invisible fourth wall. It supports realism and psychological drama, where spectators observe rather than participate.

Related: Presentational acting, Fourth wall

A colored transparent filter placed in front of a lighting fixture to tint its beam. Gel choice affects atmosphere, visibility, and color mixing on costumes and scenery.
