Just a few words for Harry T:
"Poets have explained that free verse is, despite its freedom, not entirely free. Free verse displays some elements of form. Most free verse, for example, self-evidently continues to observe a convention of the poetic line in some sense, at least in written representations, though retaining a potential degree of linkage, however there are more traditional forms. Donald Hall goes as far as to say that "the form of free verse is as binding and as liberating as the form of a rondeau",[2] and T. S. Eliot wrote, "No verse is free for the man who wants to do a good job".[3] Kenneth Allott the poet/critic said the adoption by some poets of vers libre arose from 'mere desire for novelty, the imitation of Whitman, the study of Jacobean dramatic blank verse, and the awareness of what French poets had already done to the Alexandrine in France'.[4] The American critic John Livingston Lowes in 1916 observed 'Free verse may be written as very beautiful prose; prose may be written as very beautiful free verse. Which is which ?' [5] For more on this subject and the footnotes go to:
