A strophe (/ˈstroʊfiː/) is a poetic term originally referring to the first part of the ode in Ancient Greek tragedy, followed by the antistrophe and epode. The term has been extended to also mean a structural division of a poem containing stanzas of varying line length. Strophic poetry is to be contrasted with poems composed line-by-line non-stanzaically, such as Greek epic poems or English blank verse, to which the term stichic applies.
In its original Greek setting, "strophe, antistrophe and epode were a kind of stanza framed only for the music", as John Milton wrote in the preface to Samson Agonistes, with the strophe chanted by a Greek chorus as it moved from right to left across the scene.
