What is a cue in stagecraft?

A cue in stagecraft serves as a crucial signal that prompts an actor or crew member to take a specific action. This can include numerous activities, such as entering or exiting the stage, starting or stopping a particular piece of lighting or sound, or executing a special effect. Cues are vital for maintaining the flow of a performance, ensuring that all elements come together seamlessly at the right moments, thus enhancing the overall production.

Other options discuss elements of stagecraft but do not accurately define what a cue is. Staging techniques refer to the methods used to arrange performances, design elements relate to the visual and structural components of the set, and the main theme of a play encompasses the overarching message or ideas conveyed, which is unrelated to the operational aspect of cues within a production.
