A Glossary of Theatre Terms (A-C)

Above the title In advertisements, when the performer's name appears before the title of the show or play. Reserved for the big stars!
Amplifier Sound term. A piece of equipment which ampilifies or increases the sound captured by a microphone or replayed from record, CD or tape. Each loudspeaker needs a separate amplifier. Usually abbreviated to "amp", which is not to be confused with the measurement of electrical power.
Apron In a traditional theatre, the part of the stage which projects in front of the curtain. In many theatres this can be extended, sometimes by building out over the pit (qv).
Assistant Director Assists the Director (qv). In many ways the job varies according to the director and the assistant, but it may involve taking some rehearsals, arranging rehearsal calls...
Assistant Stage Manager (ASM) Generally deals with props and will do certain cues during the show that are specifically to do with props, onstage effects and so on. ASMs tend to do cues that involve more direct contact with the cast because the cast will know them from the rehearsal period.
Auditorium The part of the theatre in which the audience sits. Also known as the House.
Aux Abbreviation for auxiliary: an output on a sound mixing desk which sends a signal to an exterior unit, such as a signal processor (qv).
Auxiliary Return An input on a sound mixing desk through which the signal is returned to the mix (qv) after processing by an exterior unit, such as a signal processor (qv).
Backing Flat A flat (qv) which stands behind a window or door in the set (qv).
Banjo  Not the musical instrument! A rail along which a curtain runs.
Bar An aluminium pipe suspended over the stage on which lanterns are hung. These are usually designated either FoH (front of house) bars or onstage bars. They will normally be further referred to as no. 1 bar, no. 2 bar, etc. Also the place where you will find actors after the show - the stage crew will still be working!
Barn Door An arrangement of four metal leaves placed in front of the lenses of fresnel spotlights (qv) to control the shape of the light beam.
Bass Cab (Cab = cabinet) Loudspeakers (qv) which relay only low frequencies.
Bastard Prompt See Corner.
Battern A long row of floodlights (qv), wired as three or four circuits.
Beamlight Lighting term: a type of lantern which produces a parallel beam of light. In construction rather like a car headlamp, being a sealed-beam unit. Also known as a parcan or parblazer.
Beam Spread Lighting term: the area that the beam from a given lantern covers. It is usually expressed as the angle that the beam subtends at the focal plane: the smaller the angle, the narrower the beam. For example, a 16-30 profile spot will have a beam spread varying from 16° to 30°.
Beginners Those members of the cast who are on-stage when the curtain goes up. The call (qv) "Overture and beginners" is a signal to the orchestra to start the introductory music and to the cast to get into position on-stage.
Blackout Lighting term: switching all lights out at once, leaving the stage in complete darkness. See also DBO.
Blacklight Ultra-violet light. Can be in bulb or, more usually, tube form.
Blacks Black curtains at the back and sides of the stage. Also ther black clothing worn by stage crew so that they don't attract attention to themselves during scene changes when house tabs are either not used or not there!
Blocking The setting of the actors' positions and moves at the beginning of rehearsals. Occasionally known as plotting, a term usually reserved for use in lighting.
Board Another name for a control desk, either lighting (most usually) or sound.
Book (The) A copy of the script, kept by the Deputy Stage Manager, which includes all cues (qv) and notes. Also known as the "prompt copy."
Boundary Zone Mics A type of condenser mic (qv), usually on the floor of the stage at the front, which picks up everything happening onstage but able to filter out low frequencies, such as thsoe produced by footsteps.
Box Office The place where the tickets are sold. Occasionally used colloquially to mean the size of the audience ("What's the box office like tonight?"). Often abbreviated to box.
Box Set A set (qv) which consists of three walls, around a proscenium arch (qv) stage. The proscenium opening is the fourth wall. Also known as a "room set".
Break A movement made by an actor, when the direction of travel is changed: i.e. the actor breaks down left, makes a sudden movement donstage left.
Build Lighting term: the gradual increasing of brightness, as, for example, in a song the brightness might build from 80% to full by the end.
Call Generally, some sort of instruction to the company: a rehearsal call is an instruction to attend a rehearsal at a particular time; time calls are given just before each performance ("Ladies and gentlemen, this is your thirty minute call"); treasury call is pay day in the professional theatre. Note that time calls are all related to the "Beginniners" call, not to the actual time of starting the show. In other words, the 30 minute call is given 30 minutes before "Orchestra & Beginners" is called, or 35 minutes before the curtain goes up.
Cans Headphones
Cardioid A type of microphone which picks up sound in a heart-shaped (hence "cardioid") area in front of it.
Cast The list of characters in a play and the actors who play them. Also, as a verb, to allocate parts to members of a company.
Cheat To make an action on stage look realistic without actually doing what you seem to be doing; e.g. an actor looking towards the audience in the general direction of the person he is talking to, is cheating.
Check Lighting term: to lower the brightness of a lantern (qv) to zero. Synonyms are "fade out", "fade down" and "fade to blackout".
Chief Electrician (Usually abbreviated to Chief LX) He is head of the department which is responsible for the maintenance and rigging of the lighting, and the operation of the lighting plot. In act, he is usually responsible for the maintenance and repair of anything electrical in the theatre, from the stage lighting to the light in the gent's toilet! His crew are variously known as LX, electrical daymen, electrics crew, etc..
Choreographer Devises and rehearses the dance routines, following the concept laid down by the Director (qv).
Cinemoid A (now discontinued) brand name for a lighting gel or filter. Still used by old-timers (like me!) generically.
Clip Some sound mixing desks allow certain sound intensities to be "clipped" (reduced below a pre-set level) to avoid distortion.
Cloth Backdrop scenery painted on fabric. Cloths can be on a banjo (qv) (usually in the amateur theatre), can be rolled up, or can be flown (qv).
Colour Changer A remotely controlled means of changing a coloured filter over the lens of a lantern. There are three kinds: a wheel with three or four lens-sized holes into which different coloured gells can be slipped, a semaphore (like the old- fashioned railway signals) and a scroller which uses continuous, usually dichroic, filters. Scrollers (qv) are the preferred option in the modern theatre.
Colour Frame A frame which fits over the front of a lantern to held a coloured filter or gel. They can be made from metal (preferred) or a kind of cardboard.
Come down In the theatre, a show does not finish; it comes down, i.e. the curtain "comes down" to end the show.
Company Manager While the stage manager deals with what happens on stage, the company manager's job is to look after everything that happens off-stage.

Compresser
/Limiter

An electronic unit which compresses and limits the frequency range of the sounds passing through it, usually to avoid distortion when the sound is reproduced.
Condenser Mic A type of microphone which requires power (either battery or, more usually, phantom power (qv)) to run it. Condenser mics are generally more sensitive than dynamics (qv) and are more usually used for recording than for stage. However, because of their sensitivity, they do have some stage uses (see Boundary Zone Mics, PZM, shotgun mics).
Corner Short for the "prompt corner"; the place from which the Deputy Stage Manager controls the show. From here he has communication links to all parts of the the theatre and gives cues (qv) to all departments. The corner can be on either side of the stage but traditionally it is on the left (i.e. the prompt) side. Perversely some theatres have the prompt corner on the "opposite prompt" (OP) side of the stage! This is often known as a "bastard prompt". The person who is operating the corner is sometimes said to be "in the corner" and sometimes "on the book".
Corpse Not a dead body in a thriller! An actor who gets an unintended and uncontrollable fit of laughter on stage is said to "corpse".
Counterweight A method of flying (qv) in which weights are used to balance the load being carried on the wire fly lines, so that brute strength is not needed by the flyman (qv)
Cross Fade Lighting term: fading one lantern (or group of lanterns) up while fading another down.
Crossover Sound: a unit which splits sound into different frequency ranges for sending to different types of loudspeaker (qv).
Stage: the area between the cyclorama (qv) or back wall of a set (qv) and the back wall of the stage, which enables actors and stage crew to cross from one side to the other.
CSI Compact Source Iodide: a type of discharge lamp, usually used in follow-spots, which, although very small (often no bigger than a finger nail), gives a very bright, white light. A 2K CSI lamp will give the same power as a 5K tungsten. These are, needless to say, very expensive.
Cue An instruction given by the Stage Manager to one of the technical departments to take some action; e.g. LX cue 7 is the seventh instruction in the play to the lighting department. Also used in the sense of the point at which an actor must enter or speak.
Curtain Call Taking a bow in front of the audience at the end of a show. Abbreviated to "curtain" or "calls".
Cut-out A free-standing piece of scenery, e.g.a tree, cut out of board into the correct shape and painted.
Cyclorama Also known as a cyc. Normally a very large piece of white fabric, tensioned on two or more sides, which covers the entire back wall of the stage. It can be lit in various colours or have slides or gobos (qv) projected onto it. Some theatres - the Yvonne Arnaud in Guildford, for example - have plaster cycs.
