The Parodos is the second segment of the plot and refers to the song (and stylized movements or dance) which accompanies the first entrance of the Chorus on stage. The opening Chorus song serves a purely expository function in Antigone.
These two initial segments of the plot are followed by five major “Epeisodia” or episodes. In these scenes, one or more of the three central actors took the major and minor roles, along with the Chorus. The word “Epeisodian” meant, originally, the entrance of an actor to announce something significant in the plot to the Chorus. The episodes contained both typical passages and narrative or dramatic dialogues, lamentations and incidental songs or utterances by the Chorus. Each of these episodes is followed by a stasimon, a song sung by the Chorus
