299 terms
Matinee Idol
A handsome, charismatic male actor who is particularly popular with audiences, especially at afternoon (matinee) performances. The term originated in the late 19th and early 20th centuries when matinee audiences skewed heavily female. While the term is somewhat archaic, the concept persists—certain performers generate intense personal followings that drive ticket sales regardless of the production.
Industry & BusinessMelodrama
A dramatic genre characterised by exaggerated emotions, clear-cut moral conflicts, sensational plots, and stereotypical characters (virtuous heroes, scheming villains, damsels in distress). Originally, melodrama literally meant "music drama"—music accompanied the action to heighten emotion. Though often used pejoratively today, melodrama was the dominant popular theatre form throughout the 19th century.
Genres & StylesMetatheatre
Theatre that is self-consciously aware of itself as theatre—plays that reference the act of performance, contain plays within plays, or blur the line between fiction and reality. Shakespeare's A Midsummer Night's Dream (with its play-within-a-play) and Pirandello's Six Characters in Search of an Author are classic examples. Metatheatre invites audiences to think about the nature of storytelling and performance itself.
Genres & StylesMethod Acting
An approach to acting derived from Konstantin Stanislavski's system, developed in America by Lee Strasberg, Stella Adler, and Sanford Meisner (each with their own variation). Method actors seek to create emotionally authentic performances by drawing on personal experience, sense memory, and deep psychological identification with their characters. The approach has been both celebrated and controversially debated.
Acting & PerformanceMezzanine
The first balcony level of seating in a theatre, located above and overhanging the rear portion of the orchestra (stalls). Front mezzanine seats are highly prized for offering an elevated, full-stage view while remaining close to the action. In British theatres, this level is typically called the "dress circle" or "royal circle."
Venues & SpacesMezzo-Soprano
A female vocal range sitting between soprano and alto, known for its warmth, flexibility, and dramatic power. "Mezzo" (Italian for "middle") is one of the most versatile voice types in musical theatre. Mezzo-sopranos play everything from leading ladies to character roles and villainesses. Roles like Velma Kelly in Chicago, the Witch in Into the Woods, and Éponine in Les Misérables showcase the range's expressiveness.
Musical TheatreMime
The art of communicating meaning through gesture, movement, and facial expression without using spoken words. Mime ranges from the white-faced tradition associated with Marcel Marceau to contemporary physical storytelling. As a theatrical technique, mime is used when actors must convey actions without props (miming drinking from a cup) or create imaginary environments through movement alone.
Acting & PerformanceMonologue
An extended speech by a single character in a play, delivered either to other characters, to the audience, or to oneself. Monologues are a fundamental building block of dramatic writing, used to reveal character depth, advance the plot, or deliver key thematic content. Prepared monologues are the most common audition material, and actors build a repertoire of contrasting pieces.
Acting & PerformanceMorality Play
A medieval dramatic form (15th–16th century) in which allegorical characters—with names like Everyman, Good Deeds, Death, and Vice—enact a moral lesson, typically about the human soul's journey toward salvation. The most famous example, Everyman, depicts its protagonist summoning friends, family, and worldly goods only to find that none will accompany him to face God. Morality plays bridged the gap between religious liturgical drama and secular theatre.
History & TraditionsMusical Director
The person responsible for all musical aspects of a theatre production, including teaching songs to the cast, leading vocal rehearsals, conducting the orchestra or band during performances, and collaborating with the director and choreographer on how music integrates with the staging. Often abbreviated to "MD," this role is essential in musical theatre and opera.
Musical TheatreMusical Theatre
A form of theatre that combines spoken dialogue, songs, and dance to tell a story. The three key components—book (script), music (score), and lyrics—work together to create an integrated theatrical experience. Musical theatre ranges from classic "book musicals" (Oklahoma!, My Fair Lady) to sung-through works (Les Misérables) to contemporary experimental forms (Hamilton, Six).
Musical TheatreMystery Play
A medieval dramatic form presenting biblical stories—from Creation to the Last Judgement—performed by trade guilds (or "mysteries") in towns across Europe, particularly England. Mystery plays were staged on wagons or outdoor platforms during religious festivals like Corpus Christi. The York, Chester, and Wakefield cycles survive as major literary and theatrical texts. They represent some of the earliest popular theatre in the English language.
History & TraditionsNaturalism
A theatrical movement emerging in the late 19th century that pushed realism to its extreme, attempting to present life on stage with scientific accuracy and without moral judgement. Naturalist playwrights like Émile Zola and early Henrik Ibsen depicted the effects of heredity and environment on characters, often focusing on the lives of ordinary or lower-class people.
Genres & StylesNoh Theatre
The oldest surviving form of Japanese theatre, dating from the 14th century. Noh combines music, dance, and drama in a highly stylised, slow-paced performance featuring masked actors, a chorus, and a small instrumental ensemble. Themes draw from Japanese history, legend, and spirituality. Noh has influenced Western artists including W.B. Yeats and Samuel Beckett.
History & TraditionsObjective
What a character wants to achieve in a scene—their goal, desire, or intention that drives their actions and dialogue. Identifying a clear objective is fundamental to the Stanislavski approach: every moment on stage should be motivated by the character actively pursuing something. Objectives are typically phrased as "to" statements: "to persuade," "to escape," "to win forgiveness." Without a clear objective, a performance lacks direction and energy.
Acting & PerformanceObstacle
Whatever stands between a character and their objective—the opposition, difficulty, or barrier they must overcome. Obstacles create dramatic tension and force characters to adapt, strategise, and fight for what they want. Obstacles can be external (another character, a locked door, societal rules) or internal (fear, guilt, conflicting desires). The relationship between objective and obstacle is the engine of all dramatic action.
Acting & PerformanceOff-Book
The point in the rehearsal process when actors have memorised their lines and no longer carry or reference their scripts. Directors typically set an "off-book date" by which the cast is expected to have learned their parts. Going off-book allows actors to focus fully on their performance, blocking, and interaction with scene partners.
Acting & PerformanceOff-Broadway
Professional theatres in New York City with 100 to 499 seats, a tier below Broadway in scale but often equal or superior in artistic ambition. Off-Broadway has historically been a launching pad for innovative work that later transfers to Broadway. Off-Off-Broadway (under 100 seats) represents an even more experimental tier.
Industry & BusinessOlivier Awards
The annual awards recognising excellence in London's professional theatre, named after the legendary actor Laurence Olivier. Established in 1976 (originally as the Society of West End Theatre Awards), the Oliviers cover West End and other major London productions. Winning an Olivier is the highest honour in British theatre and significantly raises a production's profile and commercial prospects.
Industry & BusinessOne-Act Play
A play consisting of a single act, performed without an intermission, typically running between 10 minutes and an hour. One-act plays are a distinct dramatic form requiring economy and precision. Festivals of one-act plays are popular in community and educational theatre. Notable one-act playwrights include Anton Chekhov, Tennessee Williams, and Edward Albee.
Genres & StylesOnnagata
Male actors in Japanese Kabuki theatre who specialise in performing female roles, having trained from childhood in the specific movement, vocal quality, and aesthetic of feminine portrayal. Onnagata developed after women were banned from performing in Kabuki in 1629. The tradition continues today, and the art of onnagata performance is highly respected—the best practitioners are considered to express an idealised femininity that transcends gender.
History & TraditionsOpening Night
The first official public performance of a production, following the preview period. Opening night is traditionally a significant event—critics attend, the cast and crew celebrate at an opening night party afterward, and reviews are typically published the following day. In Broadway tradition, opening night performances receive special attention from the industry and press.
Industry & BusinessOperetta
A light form of opera featuring spoken dialogue interspersed with songs, dances, and orchestral music, typically with romantic plots and happy endings. Operetta bridges the gap between opera and musical theatre. Gilbert and Sullivan's works (The Mikado, HMS Pinafore) and Johann Strauss II's Die Fledermaus are classic examples. Operetta's influence on the development of the modern musical is profound—it established many of the conventions musical theatre still uses.
Musical TheatreOrchestra Pit
The recessed area in front of and below the stage where musicians perform during a musical or opera. The pit is typically hidden from the audience's direct view, allowing the music to support the action without visual distraction. Pit orchestras work in tight quarters, following the musical director or conductor, who must watch both the musicians and the action on stage simultaneously.
