What role does the chorus serve in general? What function does the chorus play in Sophocles’s Antigone?

In Antigone the Chorus at times directly affects the action of the play. The main functions of the Chorus are to comment on the action of the play, give back story, and to connect the play to other myths. Sophocles also uses the Chorus to expound upon the play's central themes.
