Long meter

Long metre is a verse form consisting of four line stanzas, or quatrains, of iambic tetrameter with alternate rhyme scheme a-b-a-b. Long meter is similar to Short meter, which consists of similarly rhyming quatrains of iambic trimeter; and to Common metre, which consists of similarly rhyming quatrains formed of alternating lines of iambic tetrameter and iambic trimeter.
