In Oedipus Rex, what seems to be the function of each Ode in response to the preceding scene?

It is important to focus on how the Odes that the Chorus offers
provide a commentary on the action that has just passed. They clearly provide a much wider
insight and context into the action of the play as a whole, giving us an awareness of the "common
man" of Thebes with his worries, preoccupations, superstitions and religious concerns. Therefore,
in Ode 2, following Jocasta's denunciation of Oracles and the power of Gods to work in the lives
of humans, the Chorus are sharply critical of her stance in this
respect:

Haughtiness
and the high hand of disdain

Tempt and outrage God's holy
law;

And any mortal who dares hold

No
immortal Power in awe

Will be caught up in a net of
pain.

Clearly, the Chorus is shocked
with the ease that Jocasta "disproves" the Oracle concerning Laius and the way she dismisses
Oracles in general, and thus their comments act as an alternative commentary on the action in the
play.

So, in order to proceed with your assignment I suggest that
you examine each Ode carefully and consider how it comments upon, supports or contradicts views,
characters and the action that immediately precede it. Good luck!
