From the rear of the stage to the audience, there are three zones that you can note in any Baltimore theatre: upstage, center stage and downstage. These are each divided into three or five sections, depending on the size. If there are just three sections, there will be a center, left and right in each. When in the center stage zone, right or left may be referred to simply as stage right and stage left, with only the very middle of the stage being referred to as center stage.
If your stage in Baltimore has been divided into 15 sections instead of nine, there will be a “left-center” and a “right-center” in each section, for five possible locations in each of the three zones. When you see stage directions in published plays, they are often in abbreviated form. Here’s what they mean:
DRC: Downstage Right-Center
DLC: Downstage left-center
URC: Upstage Right-Center
