Opera singers must act on stage as well as sing! This means they have to understand the stage set-up. When the stage director is rehearsing with the singers, he or she must be clear about where everybody should be at any given point in time—otherwise there could be a big traffic jam. Special terms are used to avoid confusion. For instance, “upstage” is at the very back of the stage (away from the audience) and “downstage” is at the front (near the audience).
