What type of cue is used to signal an action in performance arts?

In the context of performance arts, a cue refers specifically to a signal that indicates when an action should take place. Cues can be verbal or non-verbal and are designed to help performers time their actions, dialogue, or movements accurately within a performance. They are essential for coordination among cast members, ensuring that the timing of various elements such as lighting, sound, or scene changes aligns perfectly with the performance.

While the other terms like prompt, stimulus, and indicator might seem similar, they do not encompass the full scope of what a cue represents in this context. For instance, a prompt usually refers to a reminder or hint to encourage someone to perform, while a stimulus might imply an external factor causing a reaction. An indicator generally points out a condition or state rather than actively facilitating the timing of actions. Therefore, "cue" is the term that most accurately describes the signal for action within the performance arts.
