The Rehearsal Hall is a 70 foot wide by 50 foot deep by 30 foot high rehearsal space with full-length mirrors and ballet barres on three walls. Full-length curtains are hung for masking the mirrors and dampening the room acoustically. Usually accessible through the stage door entrance, the Rehearsal Hall has a clearly marked awning, covering the street entrance, that is used for special informal performances, such as the Wee Folk Series performances, during which young children and parents may sit either in chairs or casually on the floor.
