Because of the limitations in the theatrical presentation of a story (it must be specific in a presentational space), certain conventions in the theatrical language have been acceptable – for instance, the exposition can be presented by incidental characters in non-dramatic conversation, the soliloquy provides a means for the audience to know what the character is thinking but not saying out loud, the aside allows a character to convey something to the audience while keeping it from the other characters. Of course, the “technique” of blocking entrances and exits provides variety in dialogue, costume techniques allow insight into class, financial status, etc. All the aspects of stage language use “techniques” to provide information to the spectator. Even in Shakespeare’s day, for example, a woman appearing in public with her hair down signified madness. The audience is constantly accepting the “technique” of the invisible third wall, and the exit into the wings as a convention. The playwright has the whole “grammar” of drama at his/her disposal to tell his/her story.
