Callboy

Call boy (or call girl) is the job title of a stagehand in the theatre. They are hired by either the director, producer or stage crew chief. They report directly to the crew chief, are usually paid by the hour, and will sometimes rotate between several groups from one performance to the next.

The primary responsibility of the call boy or girl is to move from backstage to the dressing rooms and green rooms alerting actors and actresses of their entrances in time for them to appear on stage on cue. For example, they might call out, "You're on in five minutes, Miss Bernhardt."

The call boy or girl also calls the "quarter hour" and "overture and beginners,"^[1] the preparatory warning that signals for the orchestra to start the introductory music and the beginners, those performers who appear on stage at the beginning of the first act, to get into their opening positions. The call boy or girl also assists with scene changes.
