What is the term for when the audience is positioned on one side of the acting area?

The term for when the audience is positioned on one side of the acting area is known as “End-On” or “Proscenium Arch.” In this arrangement, the audience faces the performance straight on, creating a clear separation between the audience and the performers, much like in a traditional theater setting with a proscenium arch. This configuration allows for the use of backdrops and stage sets that can enhance the visual aspects of a performance, giving the audience a framed view of the action.

The other configurations involve different audience placements that affect how the performance is experienced. In a thrust stage, for example, the audience is placed on three sides, creating a more intimate atmosphere but also requiring a different approach to blocking and performance style. In a traverse stage, the audience is seated facing each other on two sides, while "in the round" refers to an arrangement where the audience surrounds the performance space completely. Each of these setups brings unique dynamics to the theatrical experience, but for the specified arrangement of one-sided audience placement, End-On/Proscenium Arch is the correct term.
