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.
