If you’re studying drama or theatre, you’ll quickly come across lots of terms that might sound confusing at first. From understudies and stage managers to matinees and blocking, theatre has its own language — but once you understand it, everything starts to make much more sense. I’ve pulled a few of the most common theatre terms out of my satchel to help you get to grips with what they mean, how they’re used, and why they matter both on and off the stage.
What is an Understudy?
An understudy is a performer who learns the role of another actor so they can step in if that actor is unable to perform. Understudies are essential in theatre because live performances can’t simply be postponed if someone is ill or unavailable. They must be ready to perform at short notice, often with limited rehearsal time. You’ll sometimes hear announcements before a show if an understudy is going on, and in many cases audiences are just as excited to see them perform.
What is a Swing?
A swing is a performer who covers multiple roles within a production, usually within the ensemble. Unlike an understudy who typically covers one role, a swing may need to learn several different parts including choreography, staging and vocal lines. This makes them one of the most versatile performers in a show, often stepping in wherever they are needed.
What does a Director do?
The director is responsible for the overall creative vision of a production. They guide performances, decide how scenes are staged, and interpret the script for an audience. Directors also work closely with designers such as lighting, set and costume to ensure everything feels connected and clear.
What does a Producer do?
The producer focuses on the practical and financial side of a production. This includes securing funding, managing budgets and ensuring the show can go ahead. Producers may also be involved in hiring key creatives and supporting how the show is promoted.
What is a Stage Manager?
The stage manager is responsible for the smooth running of the show. They organise rehearsals, communicate between departments and call cues during performances such as lighting, sound and scene changes. If something goes wrong on stage, the stage manager is usually the one keeping everything on track behind the scenes.
What is Blocking?
Blocking refers to the planned movement of actors on stage. During rehearsals, the director decides where performers stand, move and interact with props. This is carefully designed to make sure the story is clear and visible to the audience, and actors must remember this alongside their lines.
What is an Interval?
An interval is a short break in the middle of a performance. It gives the audience time to rest and allows the cast and crew to prepare for the second half. Not all shows include an interval, but many longer productions do.
What is a Matinee?
A matinee is a daytime performance, usually in the afternoon. These are often popular with schools and families, and some productions run both a matinee and an evening performance on the same day.
What is the Ensemble?
The ensemble is the group of performers who support the main roles in a production. They may appear in multiple scenes, take on different characters and help build the world of the show through movement and energy.
What are Tech Rehearsals?
Technical rehearsals, often called tech rehearsals, are when all elements of the production come together. This includes lighting, sound, set changes, costumes and special effects. These rehearsals are often slow and detailed as each moment is carefully timed before the show opens to an audience.
What is Upstage and Downstage?
Upstage and downstage describe positions on the stage. Downstage is the area closest to the audience, while upstage is the area furthest away. These terms come from older theatres where stages were slightly sloped. Directors use these terms when giving instructions, for example asking an actor to “move downstage centre” so they are clearly visible.
What is Stage Left and Stage Right?
Stage left and stage right are directions based on the actor’s perspective when facing the audience. This means stage left is on the actor’s left-hand side, not the audience’s. These terms are essential during rehearsals and performances to ensure everyone understands positioning.
What is a Cue?
A cue is a signal for something to happen during a performance. This could be an actor delivering a line, a lighting change, a sound effect or a set movement. Cues are carefully timed and often called by the stage manager to keep the performance running smoothly.
What is a Prompt?
A prompt is when an actor is given a line if they forget it during a performance or rehearsal. This is usually done by someone offstage, traditionally called the prompter, although in modern theatre this role is often managed by the stage manager or assistant stage manager.
What is the Prompt Corner?
The prompt corner is the area at the side of the stage where the stage manager or assistant stage manager is positioned during a performance. From here, they can follow the script, give cues and support the actors if needed.
What is a Cue-to-Cue Rehearsal?
A cue-to-cue rehearsal is a type of technical rehearsal that focuses only on the cues in a production. Instead of running the entire show, the cast and crew jump from one cue to the next to test lighting, sound and transitions efficiently.
What is a Dress Rehearsal?
A dress rehearsal is a full run of the show with costumes, lighting, sound and set all in place, as if it were a real performance. It is usually one of the final rehearsals before the show opens to an audience.
What is Diegetic and Non-Diegetic Sound?
Diegetic sound is sound that exists within the world of the play, meaning the characters can hear it, such as music from a radio on stage. Non-diegetic sound is added for the audience only, such as background music used to create mood or tension.
What is a Monologue?
A monologue is a speech delivered by one character, often expressing their thoughts or feelings. Monologues can be directed at other characters or spoken directly to the audience, and they are often used to reveal important information.
What is a Soliloquy?
A soliloquy is a specific type of monologue where a character speaks their thoughts out loud, usually alone on stage. It allows the audience to understand the character’s inner feelings and motivations.
What is Proxemics?
Proxemics refers to the distance between actors on stage and how this distance communicates relationships or emotions. For example, characters standing close together may suggest intimacy, while distance can suggest tension or conflict.
What is Physical Theatre?
Physical theatre is a style of performance that uses movement and physical expression as the main way of telling a story, rather than relying heavily on dialogue. It often combines elements of dance, mime and visual storytelling.
What is Naturalism?
Naturalism is a style of theatre that aims to represent real life as closely as possible. Performances, settings and dialogue are designed to feel realistic and believable, as if the audience is watching real events unfold.
What is Brechtian Theatre?
Brechtian theatre, developed by Bertolt Brecht, is a style that aims to stop the audience from becoming too emotionally involved in the story. Instead, it encourages them to think critically about what they are watching. Techniques include direct address, visible lighting and actors stepping out of character.
What is Semiotics in Theatre?
Semiotics is the study of signs and symbols and how meaning is created on stage. In theatre, everything can carry meaning — costumes, lighting, props, movement and even silence. For example, a red costume might suggest danger or passion, while dim lighting might create tension. Understanding semiotics helps students analyse how performances communicate ideas beyond dialogue.
What is Dramatic Irony?
Dramatic irony is when the audience knows something that the characters do not. This creates tension, humour or anticipation. For example, if the audience knows a character is in danger but the character does not, it builds suspense as the scene unfolds.
What is a Fourth Wall?
The fourth wall is the imaginary barrier between the actors and the audience. In most traditional theatre, actors perform as if the audience is not there. When a character speaks directly to the audience or acknowledges them, this is called “breaking the fourth wall”.
What is Ensemble Work?
Ensemble work refers to how a group of performers work together as a team. It focuses on cooperation, timing, awareness and shared energy rather than individual performance. Strong ensemble work creates a more believable and engaging production.
What is Devising?
Devising is the process of creating a performance collaboratively, often without a script to begin with. Performers and creatives build the piece through improvisation, discussion and experimentation. Devised theatre is often original and can explore themes in creative and non-traditional ways.
What is Improvisation?
Improvisation is when performers create scenes, dialogue or movement spontaneously without a script. It is often used in rehearsals to explore ideas, develop characters or experiment with different approaches to a scene.
What is a Stimulus?
A stimulus is a starting point for creating a piece of theatre. This could be an image, a piece of music, a word, a theme or a real-life event. Students are often given a stimulus in drama lessons to inspire devised work.
What is Pace in Theatre?
Pace refers to the speed at which a performance moves. This includes how quickly lines are delivered, how fast scenes change and the overall rhythm of the production. Changes in pace can create tension, excitement or emotional impact.
What is Timing?
Timing is crucial in theatre, especially in comedy. It refers to delivering lines or actions at the right moment to achieve the intended effect. Good timing can enhance humour, tension and emotional responses from the audience.
What is a Freeze Frame?
A freeze frame is a technique where performers hold a still image on stage to represent a moment, idea or emotion. It is often used in devised theatre and drama exercises to explore key themes or relationships.
What is Thought Tracking?
Thought tracking is a technique where a character speaks their thoughts out loud while frozen in a scene. This helps the audience understand what a character is thinking or feeling internally.
What is Split Stage?
A split stage is when the stage is divided into two or more areas, showing different scenes or locations at the same time. This can be used to show parallel action or contrast between characters or events.
What is Cross-Cutting?
Cross-cutting is a technique where the performance switches between two or more scenes or storylines. This can build tension, show connections between events or create contrast.
What is Minimalist Theatre?
Minimalist theatre uses very few props, set pieces or technical elements. The focus is on the actors and the storytelling, often requiring the audience to use their imagination.
I’ll be honest, once you start throwing around words like semiotics and cross-cutting, it can feel like you’ve wandered into a completely different world. But here’s the thing — you’ve probably already seen all of these in action without even realising it. Theatre has a funny way of teaching you as you go, and before long you’ll be spotting these techniques like you’ve been carrying the satchel yourself.
