What would stage management typically shout just before a show starts?

The phrase that stage management typically shouts just before a show starts is “Show Time!” This announcement serves as a clear and energetic cue that signals to the cast, crew, and audience that the performance is about to begin. It creates a sense of anticipation and excitement, serving as the final alert for everyone involved to be ready for the start of the show.

Other options such as "Fifteen Minutes!" and "Half!" are commonly used during the pre-show countdown to indicate time left before the performance begins, helping to keep everyone on schedule. "Ready to Go!" is more of a general readiness check phrase that may be used in various contexts but does not have the same specific connotation for the commencement of a performance. “Show Time!” stands out as the definitive call that the moment to perform has arrived.
