Site-Specific Theatre
Theatre created for and performed in a particular non-theatrical location, where the site itself becomes integral to the meaning and experience of the performance. Examples include plays performed in abandoned buildings, forests, swimming pools, or private homes. Site-specific work challenges conventional audience-performer relationships and often draws meaning from the history or character of its location.
Genres & StylesSitzprobe
A German term (literally "seated rehearsal") for the first time the cast of a musical sings through the full score with the orchestra or band, without staging, blocking, or costumes. The sitzprobe is a milestone in musical theatre rehearsals—it's the moment the voices and instruments come together for the first time, and it's often an emotional experience for the company.
Musical TheatreSlapstick
A style of physical comedy involving exaggerated, boisterous actions such as falls, collisions, chases, and prop-based gags. The term comes from the "slapstick" or "batacchio"—a paddle-like device used in commedia dell'arte that made a loud slapping sound when used to strike a performer. Slapstick requires considerable physical skill and precise timing to execute safely.
Genres & StylesSoliloquy
A dramatic device where a character speaks their thoughts aloud while alone on stage, revealing their inner feelings, motivations, and conflicts directly to the audience. Distinguished from a monologue (which may be addressed to other characters), a soliloquy is specifically a private moment of self-reflection. Shakespeare's "To be, or not to be" from Hamlet is perhaps the most famous example.
Acting & PerformanceSoprano
The highest female vocal range in singing, typically spanning from middle C to two octaves above. In musical theatre and opera, sopranos often play heroines, ingénues, and romantic leads. The range subdivides into lyric soprano (warm, agile), dramatic soprano (powerful, rich), and coloratura soprano (extremely high, ornamental). Many of the most iconic musical theatre roles—Elphaba, Maria, Christine—are written for sopranos.
Musical TheatreSound Design
The art of creating the aural world of a theatrical production, encompassing sound effects, ambient atmosphere, music playback, microphone placement, and the overall sonic experience for the audience. Sound designers work with directors to shape how the audience hears the show—from thunder effects and birdsong to the reverb on an actor's voice. The discipline has grown enormously with digital technology and now has its own Tony Award category.
DesignSpeed-Through
A rehearsal technique where the cast recites their lines as quickly as possible, without pausing for blocking or emotional depth, to test and reinforce memorisation. Speed-throughs (also called "speed runs" or "line throughs") are typically done without technical elements and help actors identify lines they're uncertain about before dress rehearsals begin.
Directing & ProductionSpike Mark
A small piece of tape (or paint mark) placed on the stage floor to indicate exactly where a piece of furniture, prop, or scenic element should be positioned. Spike marks ensure that set pieces land in the same spot every performance, maintaining sightlines and blocking consistency. Different colours of tape are often used to distinguish between scenes or acts.
Stagecraft & TechnicalStage Directions
Written instructions in a script indicating movement, actions, expression, setting, lighting, sound, or other elements of production. Stage directions are typically printed in italics and set apart from dialogue. Some playwrights write minimal stage directions (Harold Pinter), while others provide extensive, literary descriptions (Tennessee Williams, Eugene O'Neill). Actors and directors may choose to interpret rather than follow directions literally.
Dramatic StructureStage Door
The backstage entrance to a theatre, used by performers, crew, and staff rather than the public. The stage door is where actors enter and exit the building, and where fans traditionally wait after performances hoping to meet the cast and get autographs or photos. A stage door keeper manages access and security. "Stage door" has become synonymous with the glamour and mystique of theatre life.
Venues & SpacesStage Left and Stage Right
Directional terms describing areas of the stage from the actor's perspective when facing the audience. Stage left is the actor's left (the audience's right), and stage right is the actor's right (the audience's left). These terms, along with upstage, downstage, and centre, form the standard vocabulary for describing positions and movements on stage.
Venues & SpacesStage Manager
The person responsible for coordinating all elements of a theatrical production during rehearsals and performances. Stage managers schedule rehearsals, record blocking, manage props, call cues during performances, and serve as the communication hub between the director, cast, and crew. During the run of a show, the stage manager maintains the artistic quality of the production.
Directing & ProductionStaging
The overall physical realisation of a play on stage, encompassing blocking, set design, use of space, and the visual composition of scenes. "Staging" can refer to both the process of preparing a production and the resulting arrangement. "Minimalist staging" uses few physical elements, while "elaborate staging" might involve complex sets, effects, and large casts.
Directing & ProductionStalls
The ground-floor seating area of a theatre, known as the "orchestra" in American theatres. The stalls are closest to the stage at floor level and typically offer the most direct view of the action. The term originates from the wooden partitions (stalls) that once separated individual seats in the front rows of English theatres.
Venues & SpacesStanding Ovation
When the audience rises to its feet during the curtain call to show exceptional appreciation for a performance. While once reserved for truly extraordinary shows, standing ovations have become increasingly common in many theatre cultures. Nevertheless, a genuine standing ovation—where the audience spontaneously leaps up rather than following social pressure—remains one of theatre's most powerful expressions of appreciation.
Industry & BusinessStanislavski Method
A systematic approach to actor training and rehearsal developed by Russian director Konstantin Stanislavski in the early 20th century. The "System" emphasises emotional truth, given circumstances, objectives, obstacles, and the "magic if" (asking "what would I do if I were in this situation?"). Stanislavski's work forms the foundation of most modern Western acting training.
Acting & PerformanceStichomythia
A dramatic technique in which two characters exchange single alternating lines of dialogue in rapid succession, creating a verbal duel effect. Originating in Greek tragedy, stichomythia conveys heightened emotion, escalating conflict, or intense debate. The technique appears throughout Shakespeare and continues in modern drama whenever playwrights want dialogue to feel like a volley of verbal blows.
Dramatic StructureStock Character
A recognisable character type that recurs across many plays and dramatic traditions—the wise fool, the scheming villain, the overbearing parent, the star-crossed lovers. Stock characters draw on shared cultural expectations, allowing audiences to understand a character's role quickly. While they can become stereotypes if handled lazily, skilled playwrights subvert or deepen stock characters to create something fresh.
Dramatic StructureStrike
The process of dismantling and removing the set, lighting, sound equipment, and all production elements from the theatre after a show closes. A "strike party" involves the whole company helping to tear down the set. The term can also refer to removing a specific item ("strike that chair"). Strike typically happens immediately after the final performance.
Directing & ProductionSubplot
A secondary storyline that runs alongside the main plot of a play, often involving supporting characters. Subplots can mirror, contrast, or comment on the main action, adding thematic depth and dramatic variety. Shakespeare frequently used subplots—the Gloucester plot in King Lear parallels Lear's own story of parental blindness. Well-crafted subplots enrich the main story rather than distracting from it.
Dramatic StructureSubtext
The underlying meaning beneath the surface of what a character says—the true thoughts, feelings, and motivations that exist below the spoken dialogue. Subtext is what a character means versus what they actually say. Harold Pinter and Anton Chekhov are particularly celebrated for writing dialogue rich in subtext, where the most important communication happens between the lines.
Acting & PerformanceSupernumerary
A non-speaking, non-singing extra who appears on stage in a production, typically in crowd scenes, processions, or as background characters. Common in opera and large-scale productions, supernumeraries (often called "supers") add visual scale and atmosphere without requiring full casting. It can be an entry point for aspiring performers to experience professional stage work.
Acting & PerformanceSuspension of Disbelief
The audience's willingness to accept the conventions and artifice of a theatrical performance as real for the duration of the show. Coined by poet Samuel Taylor Coleridge in 1817, the concept describes the implicit agreement between performers and audience: we know this is a stage and those are actors, but we choose to believe in the story. Theatre depends on this shared act of imagination.
Dramatic StructureSwing
A versatile performer in a musical theatre company who learns multiple ensemble tracks (and sometimes principal roles) and fills in for absent cast members. Unlike understudies, who cover a specific role while performing their own, swings typically do not have a regular track in the show and must be ready to step into any of several parts on short notice. Swings are among the most skilled performers in any company.
