What does "calling the show" refer to in a performance?

"Calling the show" refers to the process of managing the flow of performance, which involves coordinating all aspects of a live production. This includes timing cues for lighting, sound, set changes, and the actors' entrances and exits to ensure that everything runs smoothly and as intended. The person responsible for calling the show, often referred to as the stage manager or the production stage manager, must maintain a clear understanding of the script, the timing of each scene, and the necessary cues for technical elements.

This role is crucial because it ensures that the artistic vision of the production is executed seamlessly. By managing the flow, the stage manager can dynamically adjust to any unforeseen circumstances during the performance to maintain the overall rhythm and coherence of the show.
