Theater captures the essence of human experience, which is not visible, so that the light becomes a prominent and effective presence. Silent may be undesirable in life, so silent in the theater is replaced by silence to take a philosophical dimension -as in the absurd -or a dramatic position inclose personal alienation -as in Monodrama-. This research focuses on the format of silence in theatrical performance as one of the basic pillars associated with the performance process, and try to analyze and interpret and identify the mechanism through some of the performance models of the play with the aim of activating the investment and use it in the best performance in theater.
