Theatrical scenery is that which is used as a setting for atheatrical production. Scenery may be just about anything, from a single chair to an elaborately re-created street, no matter how large or how small, whether the item was custom-made or is the genuine item, appropriated for theatrical use.
The history of theatrical scenery is as old as thetheatre itself, and just as obtuse and tradition bound. What we tend to think of as 'traditional scenery', i.e. two-dimensionalcanvas-covered 'flats' painted to resemble athree-dimensional surface or vista, is a relatively recent innovation and a significant departure from the more ancient forms of theatrical expression, which tended to rely less on the actual representation of space and more on the conveyance of action and mood. By theShakespearean era, the occasional painted backdrop or theatrical prop was in evidence, but the show itself was written so as not to rely on such items to convey itself to theaudience. However, this means that today's set designers must be that much more careful, so as to convey the setting without taking away from the actors.[1]

The more modern notion of scenery, which dates back to the 19th century, finds its origins in the dramatic spectacle ofopera buffa, from which the modern opera is descended. Its elaborate settings were appropriated by the 'straight', or dramatic, theatre, through their use in comic operettas, burlesques, pantomimes and the like. As time progressed, stage settings grew more realistic, reaching their peak in theBelasco realism of the 1910-'20s, in which complete diners, with working soda fountains and freshly made food, were recreatedonstage. Perhaps as a reaction to such excess and in parallel with trends in the arts andarchitecture, scenery began a trend towards abstraction, although realistic settings remained in evidence, and are still used today. At the same time, the musical theatre was evolving its own set of scenic traditions, borrowing heavily from theburlesque andvaudeville style, with occasional nods to the trends of the 'straight' theatre. Everything came together in the 1980s and 1990s and, continuing to today, until there is no established style of scenic production and pretty much anything goes. Modernstagecraft has grown so complex as to require the highly specialized skills of hundreds of artists and craftspeople to mount a single production.
The construction of theatrical scenery will be frequently one of the most time-consuming tasks when preparing for a show. As a result, many theatres have a place for storing scenery (such as aloft) so that it can be used for multiple shows. Since future shows typically are not known far in advance, theatres will often construct stock scenery that can be easily adapted to fit a variety of shows. Common stock scenery types include:[2]
