Stage blocking: This is a term used when a theatre director directs an actor’s movement and positioning on the stage. In most plays the stage directions have been written in the scripts to help the actors with their movement on the stage when acting.
Sightlines: This is a line of sight between the audience and the stage; a good sightline will help the audience see the whole stage.
Stage directions: This is a similar term to stage blocking as the actors receive directions from the director; this involves the physical movement of the actors on stage. The actors are supposed to note the directions in their script.
Upstage: This is used for the actors based at the back of the stage to keep them organised.
Downstage: This is used for the actors, who are based in the front of the stage, this is important as the audience has a great view of the actors.
Stage right & stage left: This is simply actors based on the left and right halves of the stage.
