The purpose of the apron in a proscenium theatre is to extend the stage area in front of the proscenium arch, which is the frame separating the stage from the audience. The apron allows performers to enter and exit the stage from downstage (closer to the audience), providing them with more space to perform or interact with the audience. It also allows for greater intimacy between the performers and the audience, creating a more immersive theatrical experience. Additionally, the apron can be used for various staging purposes, such as placing set pieces or props, or it can serve as a designated performance area for specific scenes or interactions.
