Nonmetrical, nonrhyming lines that closely follow the natural rhythms of speech. A regular pattern of sound or rhythm may emerge in free-verse lines, but the poet does not adhere to a metrical plan in their composition. Matthew Arnold and Walt Whitman explored the possibilities of nonmetrical poetry in the 19th century. Since the early 20th century, the majority of published lyric poetry has been written in free verse. See the work of William Carlos Williams, T.S. Eliot, Ezra Pound, and H.D.
