The role of the DSM in rehearsal is to keep track of all actor movements (known as blocking) in the prompt script.
The diagram on the right shows a proscenium stage, however other stage layouts (such as theatre in the round, arena staging, traverse, site-specific, and some types of thrust stage) will not be as clearly defined.
In these cases, the points of a compass could be used (e.g the entrance door may be NORTH, so the actor enters N then walks South East).
In the Round staging could use a clock. Again, a clearly defined location is 12 o'clock.
Stage Write is an app for iPad which simplifies the recording of moves and choreography
More coming soon
