what function did the chorus serve in classical greek theatre
Greek chorus Plays of the ancient Greek theatre always included a chorus that offered a variety of background and summary information to help the audience follow the performance. They commented on themes, and, as August Wilhelm Schlegel proposed in the early 19th century to subsequent controversy, demonstrated how the audience might react to the drama.[3] According to Schlegel, the Chorus is "the ideal spectator", and conveys to the actual spectator "a lyrical and musical expression of his own emotions, and elevates him to the region of contemplation".[4] In many of these plays, the chorus expressed to the audience what the main characters could not say, such as their hidden fears or secrets. The chorus often provided other characters with the insight they needed.[citation needed]
Greek tragedy The structure of Greek tragedy is characterized by a set of conventions. The tragedy usually begins with a prologue, (from pro and logos, "preliminary speech") in which one or more characters introduce the drama and explain the background of the ensuing story. The prologue is followed by the parodos(entry of the characters/group) (πάροδος), after which the story unfolds through three or more episodes (ἐπεισόδια, epeisodia). The episodes are interspersed by stasima (στάσιμoν, stasimon), choral interludes explaining or commenting on the situation developing in the play. The tragedy ends with the exodus (ἔξοδος), concluding the story. Some plays do not adhere to this conventional structure. Aeschylus' "The Persians" and "Seven Against Thebes" for example, have no prologue.
