The Horatian Ode: This kind of Ode has been named after the Latin poet, Horace, who imitated Pindar but with far reaching modifications. The Horation Ode consists of a number of stanzas with a more or less regular metrical structure but without any division into triads of the Pindaric. It may be rhymed or unrhymed. This kind of Ode is light and personal (not choric) without the elaboration and complexity of the Pindaric. Unlike the more formal Pindaric ode, the Horatian ode traditionally explores intimate scenes of daily life.
The Horatian Ode is simply a stanzaic form in which all stanzas are structured in the same pattern at the discretion of the poet. (rhyme, meter, number of lines etc.), more technically it is “nonce stanzaic” or a “homostrophic” ode (ode made up of same structured stanzas created specifically for that poem).
