To continue with Drow's work on supplying you with words:
- Proscenium - the arch at the front of the stage which defines the limit of the stage and its action
- Drop - a piece of scenery, usually in the back of a set, in which case it's called a backdrop, which is suspended from a metal bar and is raised and lowered.
- Scrim - a gauze curtain which is semi-transparent or can be nearly opaque depending on how it is lit. Nearly always hung from a rail, like a drop. It has to be weighted with pipe in the hem at the bottom to keep it hanging straight without wrinkles. The effect of a scrim is to cancel perspective -- anything you see behind it, you see in a flat plane.
- traveler - a curtain which is in two parts and which opens and closes sideways, the two halves going offstage to left and right.
- fly - v., to raise [a drop or curtain hung from a rail] off the stage. n. a curtain which rises in this manner
