Answer and explanation:
Three conventions used in the Greek Theatre that make classical Greek production so much different than theatre production for modern audiences are:
- Choir. In the ancient greek theatre music was extremely important, so that is reason why the choir used to have a major role during these plays.
- Number of actor. In the ancient greek theatre no more than three actors were allowed on stage.
- Number of acts. In the ancient greek theatre no more than three acts could be displayed during the play.
