A classical greek poem modeled on the choric ode and usually having a three-part structure consisting of a strophe, an antistrophe and an epode.

The verse form of Shelley's "Ode to the West Wind" has five strophes, and each strophe is exactly the same in form.

And you can hear them together, Yeats moving from one to another with, oh, incredible speed and agility in that final strophe of the poem, on the next page.
