Tableau
A moment in performance where all action freezes and the actors hold their positions, creating a still, picture-like image on stage. Tableaux (plural) can be used for dramatic emphasis, transitions, or to begin and end scenes. The technique, also called "tableau vivant" (living picture), has been used in theatre since the 18th century and remains a powerful staging tool.
Dramatic StructureTabs
A common informal term for stage curtains, particularly the main front curtain (the "house tabs" or "main tabs") and the curtains hanging in the wings ("tab tracks"). The term derives from "tableau curtains," which were drawn to the sides to reveal a stage picture. "In tabs" means performing in front of a closed curtain, often while a set change happens behind—a technique common in pantomime and variety.
Stagecraft & TechnicalTalkback
A post-performance discussion between the audience and members of the creative team, cast, or special guests. Talkbacks offer audiences a chance to ask questions, share reactions, and gain deeper insight into the production. They're particularly common with new plays, productions dealing with social issues, and educational programming. Also called a "post-show discussion" or "Q&A."
Industry & BusinessTech Rehearsal
A rehearsal focused on integrating all technical elements—lighting, sound, set changes, special effects, projections—with the performance. Tech rehearsals (or "tech") are typically the first time the full production comes together in the performance space with all equipment. They can be lengthy and painstaking, as each cue is set, adjusted, and recorded.
Directing & ProductionTech Week
The intensive final week of rehearsals before a show opens, during which all technical elements—lighting, sound, set changes, costumes, props—are integrated with the performance for the first time. Tech week typically includes cue-to-cues, dry tech, wet tech, dress rehearsals, and previews. It's notoriously demanding, often involving very long days for everyone involved. Theatre people sometimes call it "hell week."
Directing & ProductionTenor
The higher male vocal range, prized in both opera and musical theatre for its brightness, power, and emotional expressiveness. Tenors typically play romantic leads and heroes. The range subdivides into lyric tenor (smooth, flexible), dramatic tenor (powerful, ringing), and heldentenor (heroic). From Jean Valjean in Les Misérables to the Phantom in The Phantom of the Opera, tenor roles dominate the musical theatre canon.
Musical TheatreTessitura
The range of pitches within which a vocal part predominantly sits—not the extreme highs and lows a singer can hit, but the "comfortable working range" where most of the notes fall. Tessitura is crucial in casting: a role might technically be within a performer's range but exhausting if the tessitura sits at the top of their voice for extended periods. Smart composers write tessituras that showcase a voice type's strengths.
Musical TheatreTheatre in Education
A form of theatre (often abbreviated TIE) that uses performance, workshops, and interactive techniques to educate young people about specific topics—from history and science to social issues like bullying, consent, and mental health. TIE companies visit schools and create participatory experiences where students engage directly with the material. It bridges the gap between classroom learning and the emotional power of live performance.
Genres & StylesTheatre in the Round
A staging configuration where the audience sits on all sides of the performance space, surrounding the action. Also called "arena staging," this format creates an intimate relationship between performers and audience but presents challenges for blocking (actors must avoid turning their backs to any section for too long) and set design (tall scenery would block sightlines).
Venues & SpacesThrust Stage
A stage configuration that extends out into the audience, with seating on three sides. The thrust combines the presence and intimacy of theatre in the round with the staging possibilities of having a backstage area. Many Elizabethan theatres (including Shakespeare's Globe) used thrust stages, and the configuration remains popular in contemporary theatre design.
Venues & SpacesTony Awards
The annual awards recognising excellence in Broadway theatre, officially called the Antoinette Perry Awards. Established in 1949, the Tonys are the highest honour in American theatre, covering categories including Best Musical, Best Play, Best Direction, and all major design and performance disciplines. The televised ceremony raises the profile of Broadway shows and can dramatically boost ticket sales for winners.
Industry & BusinessTops and Tails
A rehearsal technique that practises only the beginnings and endings of scenes, focusing on transitions, entrances, exits, and set changes rather than running full scenes. Tops and tails help polish the moments that are most technically demanding and most visible to an audience—the seams between scenes where the illusion can easily break.
Directing & ProductionTouring Production
A theatrical production that travels to multiple venues across a region, country, or internationally, bringing the show to audiences beyond the original city of production. Tours range from first-class national tours (replicating the original production at full scale) to smaller bus-and-truck tours. Touring is how most people outside London and New York experience professional theatre, and it's a major revenue source for commercial productions.
Industry & BusinessTragedy
One of the oldest dramatic genres, originating in ancient Greek theatre. Classical tragedy depicts the downfall of a noble protagonist brought about by a combination of fate, character flaws, and forces beyond their control. Aristotle defined tragedy as evoking pity and fear to achieve catharsis. Shakespeare's tragedies (Hamlet, King Lear, Macbeth, Othello) are cornerstones of the Western canon.
Genres & StylesTragicomedy
A dramatic genre that blends elements of both tragedy and comedy, often featuring serious themes treated with humour or tragic situations that resolve happily. Shakespeare's late plays (The Winter's Tale, The Tempest) are often called tragicomedies. Modern playwrights like Chekhov and Beckett masterfully blend comic and tragic elements, reflecting life's tendency to mix laughter with sorrow.
Genres & StylesTransfer
When a production moves from one theatre to another—typically from a smaller or regional venue to a larger commercial one. The most common transfers move shows from Off-Broadway to Broadway, or from fringe/regional theatres to the West End. A transfer signals commercial confidence in a production. Not all transfers succeed—a show that thrived in an intimate space may struggle in a larger house.
Industry & BusinessTrap
An opening in the stage floor through which actors, props, or scenic elements can appear or disappear. Traps have been used since Elizabethan theatre for supernatural entrances and dramatic reveals. A "trap room" or "cellar" sits beneath the stage to accommodate these effects. The most famous is the "grave trap," traditionally used in Hamlet's graveyard scene.
Stagecraft & TechnicalTraverse Stage
A staging configuration where the audience sits on two opposite sides of a long, narrow playing area, like spectators at a tennis match. Traverse staging creates an intimate, almost voyeuristic relationship between audience and performer, and forces creative blocking since actors always have their back to half the audience. It's particularly effective for confrontational or corridor-like scenes.
Venues & SpacesUnderscore
Background music played beneath spoken dialogue or stage action to create atmosphere, build tension, or support emotional moments without being the primary focus. Underscoring is a fundamental tool in musical theatre, film, and television. A skilled composer uses underscore to guide the audience's emotional experience subtly—the audience feels its effect without necessarily being consciously aware of it.
Musical TheatreUnderstudy
A performer who learns a principal role so they can step in if the regular actor is unable to perform due to illness, injury, or other absence. Understudies attend rehearsals, learn blocking and business, and must be ready to go on at short notice—sometimes mid-performance. A "standby" is similar but typically waits in the theatre rather than performing another role in the show.
Acting & PerformanceUpstage
The area of the stage farthest from the audience. Like "downstage," the term originates from raked stages where actors walked "up" the slope when moving away from the audience. "To upstage someone" also means to steal focus from another actor—originally by moving upstage and forcing the other actor to turn away from the audience to face them.
Venues & SpacesVamp
A short musical passage repeated as many times as needed to cover stage business, dialogue, or an actor's entrance before the next section of a song begins. The conductor watches the stage and cues the orchestra to move on when the moment is right. Vamps give performers flexibility—if a costume change runs long or an entrance is delayed, the vamp simply keeps repeating.
Musical TheatreVaudeville
A genre of variety entertainment popular in the United States and Canada from the 1880s to the 1930s. Vaudeville shows featured a series of unrelated acts—comedy, song, dance, acrobatics, magic, animal acts—performing on the same bill. Vaudeville circuits launched many careers and influenced the development of musical theatre, comedy, and television variety shows.
Genres & StylesVenue
The building or space where a theatrical performance takes place. Venues range from purpose-built theatres with proscenium stages to converted warehouses, outdoor amphitheatres, black box studios, and found spaces. The choice of venue significantly affects the audience experience, staging possibilities, and the economic model of a production.
