The Chorus and the significance of the Choric odes in Oedipus Rex play ?

The Chorus of Theban Elders is a group of men who serve as an emotional sounding board and expositional device in the play, reflecting on the plot developments while asking important philosophical questions. The Chorus speaks as one person, but occasionally, single Chorus members would have delivered lines. They might be considered somewhat meta-theatrical - operating within the confines of the play while also having the power to step outside the boundaries of the mundane plot.
