The Headset Voice Behind Every Stage Cue
In a theater, the actors, lights, music, and scenery changes all have to arrive at exactly the right second, and someone has to hold it together. That person is the stage manager, who sits backstage or in a booth wearing a headset and watching the show from start to finish.
The stage manager's most important tool is the prompt book, a thick binder that holds the script along with notes about every cue. A cue is a signal that something should happen, such as a lighting change, a sound effect, or an actor's entrance. Before each cue, the stage manager says "standby" over the headset so everyone is ready. Then, at the exact right moment, comes the word "go," and the crew carries out the cue. A single show may have hundreds of these moments.
The job begins long before opening night. During rehearsals, the stage manager records every movement and change in the book, schedules the actors, and writes a report after each day so the designers and crew know what was decided. After the show opens, the stage manager is the one in charge of running each performance.
Safety is part of the role too. If something goes wrong, such as a broken piece of scenery or a performer who is hurt, the stage manager has the authority to pause the show. Staying calm is essential, because the cast and crew look to this person for direction. When everything works, the audience sees only a smooth performance and never knows how many people, guided by one calm voice, made it happen.
