Show Calling and Cue Execution
When a show has more than a handful of cues, one person runs it in real time: the caller — usually the stage manager — reads from an annotated script and calls every cue over comms so lighting, video, audio, fly and spots all hit the same moment. The whole rhythm of the show lives in that one voice; the operators execute, but the timing is called. A show that feels tight and a show that feels ragged are usually the same rig with a different caller.
The discipline is built on two words. "Standby" is the warning: the caller names the department and cue — "Standby LX 47" — a few lines before it lands, so the operator gets their finger on it and confirms. "GO" is the execution word, and it is sacred: nobody says "go" for anything else on that channel, because a stray "go" fires a cue. The caller lands the GO on the action — the word, the beat, the door opening — not after it, since a cue called late has already missed the moment it was meant to punctuate. Noisy or sightline-blind positions get cue lights: warning on, go on the light-out.
The calling script is not written on the night — it is built during tech rehearsals, every cue placed, every standby noted a few lines early, every tricky sequence timed and rehearsed until the caller owns it. A well-called show is invisible: the audience never sees the machinery, only the moments landing where they should. A badly-called one shows instantly as cues that arrive late, early, or bunched — which is why the caller, not any single operator, is the person holding the show together.
Standby warns, GO executes — and nothing else on that channel says GO.
