Glossary of Technical Theatre Terms

Administration


10 OUT OF 12
(USA) A contractual term for a long all-day actor (or crew) call. A typical contract will have at least one of these days, when the actors may be kept at work for 10 hours out of a maximum of 12. During the 12 hour period covered (e.g. 9am to 9pm) there will be either two 1 hour breaks or one two hour break for food, and a total of 10 hours of work. Whilst the work day is long, the intensity allows a great deal of progress to be made. American Actors's Equity only allows a period of 10 out of 12 rehearsal during the 7 days before a performance opens.

ABTT
ABTT Logo (from the ABTT website) (UK) The Association of British Theatre Technicians, which was formed in 1961 as a charity, to provide a forum for discussion among theatre technicians, architects and managers of all disciplines, and disseminate information of a technical nature, to all its members.

AUDIO DESCRIPTION
A service greatly appreciated by those with impaired vision, Audio Description involves a describer sitting at the rear of the auditorium (in the booth if there is room) providing a narration describing the action on stage. The skill is in not getting in the way of the on stage dialogue, sound effects or other audible movements on stage, but filling in where vision would help with the plot.

CLOSING NIGHT
The final performance of a show in front of a paying audience. 
Although some amateur groups enjoy playing pranks on each other on the last night, this should not happen in professional theatre - audiences that have paid for the performance should be given the same performance each time, and not run the risk of the performance falling apart because the cast are making each other laugh. A tightly rehearsed performance, involving moving scenery, flying items, complex choreography, rehearsad stage combat etc risks hurting or injuring performers (or worse) if the rehearsed sequences are deviated from. 

COMMISSION

There are often House Comps, which are good seats not sold to the public until others are sold out, which are used for VIP guests. 
In the past it had to be initialled by the General/House/Company Manager to ensure its authority, and a record kept by the Box Office Manager.

Deduction made by the Bricks & Mortar Management from its final payment to the Visiting Management, for expenditure incurred by the theatre on behalf of the Visiting/Touring Management. The amount charged varied according to the management's contract, but could include electricity used, staff over and above the normal crew, and even the 'first night thank you' reception

CURTAIN TIME
The advertised start time of the performance. This may be delayed by the late arrival of a large party, but regularly starting late because of box office queues should be avoided.

DARK
A venue that has been closed to the public. Some theatres go dark temporarily during production periods, when the next show is in preparation on stage. To keep the audience (and their money) coming in, some venues show films or have other activities not involving the stage.

DDA
Acronym for the Disability Discrimination Act (DDA) which became law in 1995 in the UK. It covers similar ground to the Americans with Disabilities Act, which became law in 1990. Both Acts are designed to outlaw any kind of discrimination against people with any form of disability.

GRAPEVINE
The theatre community is very close, and news/rumours often spread via unofficial routes. This so-called GRAPEVINE means that people are often well-informed about latest news. It is also very important to make a good impression on everyone you meet in the business, as bad impressions will be spread around the grapevine very quickly. Modern tools such as Twitter have made the grapevine even more widely spread, and great care must be taken to not publish anything on Twitter that you wouldn't say to someones face.

HEALTH AND SAFETY

PROFESSIONAL
Normally used for someone who's regularly paid for a particular job (as opposed to an amateur, who does it for fun). A professional attitude is essential when working in the theatre - this means you have to behave as if you were being paid. The theatre world is a very small community - if you behave badly or upset someone, it's highly likely you'll meet them again, and they will remember you!

REDUCED VISIBILITY / RESTRICTED VIEW
Often used to describe a seat in an older theatre from which some parts of the stage are obscured either by columns supporting the seating, or because it's at the side of the venue, or behind a balcony railing. Usually cheaper than other seats, and often not quite as bad as they sound. More modern venues are built with the intention that every seat is a good one. Older venues, particularly in large cities, may have been built as variety houses, where the main act was downstage centre, and as long as that was clearly visible, the seats were all fine. 

REGIONAL THEATRE
1) (USA) A regional theatre, or resident theatre, in the United States is a professional or semi-professional theatre company that produces its own seasons. The term regional theatre most often refers to a professional theatre outside New York City. A regional theatre may be a non-profit, commercial, union, or non-union house.

ROYALTIES
The prescribed fee paid to an author or his agent for the performing rights of a play.

SHOW ELEMENT
Term for an item of scenery or prop required for a production.

SMOKE DETECTORS
Smoke Detector (Photo-Electric sensor) Many theatre buildings have complex fire alarm systems installed. Some theatre spaces have smoke detectors in them, which trigger a fire alarm when the space fills with smoke. The use of SMOKE MACHINES in these spaces can (and does) result in expensive call-outs of the fire department and evacuated auditoria.
There are special heat-sensitive detectors called RATE OF RISE detectors which trigger a fire alarm when the temperature rises faster than it should normally. Properly calibrated (and regularly tested) these can be as effective than the smoke detectors (which work by 'seeing' smoke particles in the air). If it's not possible to get Rate of Rise detectors installed in your theatre space instead of smoke detectors, you may be able (subject to local building regulations and local fire department advice) to isolate the smoke detectors for the duration of the performance when you use smoke effects. Properly designed alarm systems incorporate timed isolation, so that smoke detectors are only off for a specific period, and automatically come on after that period.

SOLT

SRO
Abbreviation for Standing Room Only (i.e. there are no seats left in the auditorium). Standing room is not available in all venues, and depends on the number of people the licencing authority has licenced the venue for.

THEATRE ETIQUETTE
There are a wide range of types of theatre across the world, and no standard etiquette which apples to every venue. 
However, there are some base rules for audience members. 
1) Arrive on time - latecomers are disruptive to other audience members and the performers
2) Do not eat during the performance. Some performances allow you to take a drink in with you, but eating noisy food is frowned on. Sweets / candies are fine, but avoid noisy wrappers. Save any larger food (especially anything smelly) until after the show. 
3) Do not film or record the performance in any way. This is always against the rules, and will result in staff warning you, disrupting the performance. Do not take photos during the show. 
4) Turn off ringtones. If you need to keep your mobile on, please make it silent. Do not look at the phone during the performance. 
5) Dress appropriately - you are not expected to wear full evening dress at the theatre (except for formal events) so wear comfortable smart casual clothing. Remove hats during the show. 
6) Show appropriate appreciation (laughing at jokes, applauding at suitable times) but do not sing along or be too vocal at your favourite bit. 
7) Do not talk during the performance
8) Use the toilet before the performance or during the interval - leaving your seat during the show disrupts the performance.

THEATRE IN EDUCATION
Often abbreviated to T.I.E. The use of theatrical techniques to educate, covering social issues or topics on the school's syllabus.

THEATRE ROYAL
Common name for theatres in the UK. The Theatre Royal, Bristol is the oldest working theatre in the country, opened in 1766.

TICKET TOUT
Also known as Scalping, the process of reselling tickets at higher than face value is known as touting. They are often vastly over-priced. Many shows require ID to prove that the person holding the ticket is the same person named on the ticket, and tickets are not transferable between people. 

TMA
Theatrical Management Association (UK) has since 1894 represented and supported theatrical organisations all across the UK. In 2014 the organisation changed it's structure and membership plans and is now known as UK Theatre.
UK Theatre Website

TRANSFER
When a production is popular, it sometimes moves to a new venue, but with the same production team and cast. This may be to a new part of the country, or to another venue in the same area. The move is known as a TRANSFER. 
If a UK production starts in a regional theatre, it may aspire to a West-End Transfer, into the London theatre district. 

TRIGGER WARNINGS
Some audience members may be upset by particular themes that may be featured in some plays.
It's important that the creative team are aware of these themes, and how they may affect audience members, and if necessary consult with local support groups or charities that can provide advice on how to deal with the issues sensitively.
Although some venues may list the themes in advance publicity, others (such as The Old Vic in London) prefer to keep the trigger warnings unseen unless audience members ring the theatre in advance.

TRYOUT
A fully-staged run of a show in a provincial location before the show opens in a higher-profile location such as the West End of London or Broadway in New York.
The tryout run allows the show to be fine-tuned, to amend (or cut) sections which are unnecessary or don't work, and can also build word-of-mouth, and enable the production to have publicity photos etc before the show arrives at its' final destination for a (hopefully) long run.
Although many Broadway shows use out-of-town tryouts (e.g. Dear Evan Hansen (Washington DC), Frozen (Denver)), there are notable exceptions. Spider-Man Turn Off The Dark was too technically complex to be set up in another venue, so the show had a hugely extended run of previews on Broadway, and suffered with many technical and logistical issues, as well as the departure of a key member of the creative team. However, shows such as Book of Mormon and School of Rock opened 'cold' on Broadway and have gone on to huge success. The cost of tryouts is increasing (see OnStage Blog) so a tryout is no longer the only option.
See also PREVIEW

TURNAROUND
The changeover between one show and the text. It's important that the administration team scheduling the performances takes into account the time it will take to reset the stage back to 'clear' and then set up for the next show, ideally not involving overnight work!
