Which term is used to refer to the area where the actors and audience share the same space?

The term that refers to the area where the actors and audience share the same space is typically associated with a less formal, more intimate setting found in a black box theatre. In a black box theatre, the environment is flexible and can be arranged in various configurations, allowing for close interaction between the performers and the audience. This layout enhances the experience, facilitating a more immersive atmosphere where the audience feels a part of the performance.

Other terms like proscenium arch and thrust stage refer to specific stage configurations that create a physical separation between actors and audience. The proscenium arch frames the stage and establishes a clear boundary, while the thrust stage extends into the audience area but still maintains a defined separation through its structure. An open stage may also suggest a lack of barriers, but it typically is less formal compared to the setup of a black box theatre, which is designed explicitly for flexibility and intimacy in actor-audience interactions.
