The action a play represents is enacted, it is made present through the actors' bodies, through their portrayal of characters; it is not told in the form of a story. A play, lacking a narrator, is not a narration.

Do all plays have a narrator?

Generally, plays do not have narrators.

Is there a narrator in drama?

Narration is a technique whereby one or more performers speak directly to the audience to tell a story, give information or comment on the action of the scene or the motivations of characters. Characters may narrate, or a performer who is not involved in the action can carry out the role of 'narrator'.
