| The Space The physical space of the performance.  
                Are the stage 
                  and house enclosed? What are the 
                  dimensions of the acting area? What is the shape of the performance area? What is the 
                  shape of the house? 
 What is the Shape of the Performance 
                Area? 
  The 
                shape of a performance area also shapes the audience area, especially 
                in a built theatre. It also determines focus and the degree of 
                scenic possibilities.
 Theatre Shapes:  Proscenium. 
                Probably the most common shape in Western theatre is the proscenium 
                because of its ties to how history shaped theatre architecture 
                and influences that historically traveled in the theatre world. 
                The proscenium space places the audience facing the stage generally 
                in one direction. At times, the house is configured in such a 
                way that a patron actually faces another part of the house, such 
                as the box seating near the proscenium. However, once the performance 
                begins, in order to see the performance, the audience must turn 
                toward a set opening. The audience sees the performance through 
                a rectangular frame; consequently, the proscenium distinctly separates 
                performance from audience. With the proscenium, fewer patrons 
                are close to the performance than with other shapes, so physical 
                distance becomes a true factor when creating experience. The proscenium 
                can be either with the arch or without the arch. A proscenium 
                type of theatre without the arch is called the Open Proscenium.

                 Cinema. The cinema type of theatre structure is an offshoot of the proscenium. Early movie theaters were converted proscenium theatres. Usually, patrons face one direction and the screen is framed.
 
                   Conclave Cinema. IMAX theatres often have a conclave cinema structure, determined by the shape of the screen. The audience space shape, however, remains the same as in the proscenium.
  Surround Cinema. Some screened facilities, like a planetarium, have the screen surrounding the audience. The audience shape, then, changes into an around where the audience members, facing each other in a circle, can see the part of the screen they are facing.
 
  Thrust. The thrust or three-quarter stage configuration places the audience 
                on three sides of the performance space. Patrons seated in one 
                area will have a different experience than a patron seated in 
                a different area because each will be seeing the performance from 
                different perspectives. The manipulation of focus through directing 
                and design is a key factor in producing on the thrust stage. The 
                upstage area offers complex scenic possibilities, and sometimes 
                is an extension of the proscenium type of stage. Also, because 
                there is more stage area, more patrons can sit close to the performance 
              space.

                The arena or the theatre-in-the-round space configuration places 
                the audience surrounding the performance area. More patrons can 
                sit close to the performance space in the arena configuration 
                than in any other shape. Because the arena shape can offer only 
                minimal scenic possibilities, there is more of a demand on the 
                audience to imagine the drama's locale. The space haunts us back 
                to primitive theatre and a natural configuration of the circle 
                arrangement. The configuration's demand for imagination and its 
                natural structure to form community has the potential to help 
                create a vibrant and communal experience for the patron.
  Flexible. 
                The flexible space configuration offers the director and designer 
                choices for the space to configure either as thrust, proscenium, 
                or arena staging. This type of staging usually is found in experimental 
                or black-box theatres, although modern theatre designers are designing 
                flexible stages in a much larger space.
 Music Concert Shapes:  End 
                Stage. The end stage prevails as the space configuration for music recitals. Because of the lack of scenic 
                possibilities with the end stage, few theatre productions use 
                it. This shape is primarily designed to meet acoustical needs, and is only a modern shape.
