This module represents a summary regarding the choral rehearsal and concert risers. In many situations choral rehearsals are held in rooms where the singers are sitting on the same level. This is not the optimal rehearsal situation but is often the only one available. Care should be taken to position the singers so they can easily see the conductor. Commercial rehearsal risers are available but they are not inexpensive. Performance risers are plentiful and, if one does not have them, they can often be rented at a nominal fee. "Concert risers are important for visual and aural effect.
