What is a 'Bastard Prompt' used for?

A 'Bastard Prompt' refers to a specific condition where the prompt corner, which is typically where the stage manager cues the show from, is located on stage right instead of the usual stage left. This term is used in theater to accommodate various stage layouts or production requirements. By designating the prompt corner in a different location, it allows for effective communication and cueing between the cast and the stage management team.

The other options do not accurately describe the purpose of a 'Bastard Prompt'. For instance, signaling the end of a performance or indicating a scene change involves different types of cues and signals, not specifically related to the location of the prompt corner. Similarly, cuing background music pertains to audio cues that can occur from any position without the necessity of a prompt corner's specific location. Understanding the context of a 'Bastard Prompt' helps in grasping the overall organization and operation of a theater production.
