Realistic or complex stereo placement and movement, however, becomes more difficult for live performance. This is because you have a stage picture as well as a stereo picture to worry about. We cannot go into the subject in detail here, except to advise against attempting realistic and precise stereo placement when performing before a live audience. Stage Blocking The general principles of stereo blocking resembles those for stage blocking. The conventional proscenium playing area is divided into a checkerboard of fifteen equal blocks.
Important action takes place downstage, the most important down left.
The next strongest playing area is down center. Strongest area for entrances and exits is up-center. Sets are frequently in forced perspective, because a shallow stage carries sound better than a deep one. In blocking, stage directors concern themselves with the stage picture. Even when the action takes place on only a portion of the total stage, the stage picture must balance or dress the playing area so that the audience can see.
