There is sweet music here that softer falls
Than petals from blown roses on the grass,
Or night-dews on still waters between falls
Of shadowy granite in a gleaming pass,
Music that gentlier on the spirit lies
Than tired eyelids upon tired eyes.
Tennyson, Lotos Eaters.
It should now be clear that prose and verse are not so antithetical as is often supposed; that they are only different forms of the same substance, language; two branches from the same root. At certain points they overlap and are practically one; at other points the divergence is obvious but not great; and even in their extreme differences the common basis of the rhythms is the same. In both prose and verse are the same relations of time, stress, and pitch, except that in verse the arrangement and order of them are according to a perceptible pattern. Verse is but prose fitted over a framework of metre. Herein lies the whole art of versification, the whole psychology of poetic rhythm, the whole problem of metrical study and investigation.
We must always remember that "a line of verse is a portion of speech-material with all its phonetic features (corresponding to its ethos as well as its logos) adjusted, without violence, to a fixed and definite metrical scheme. The two entities, metrical scheme and portion of speech-material adjusted thereto, are distinct and the chief study of the metricist is the manner of adjustment of the latter to the former, the way in which a suitable portion of phonetic liquid is chosen and poured into metrical bottles."[21] Only after having grasped what can be grasped of the subtleties of prose rhythm, and having learned the common forms and patterns of metre, can we put the two together, recognize their new unity, perceive the new rhythmic beauties, harmonies, modulations that spring from their mutual adjustment.
A word may be added here, though the subject is one rather of æsthetics than of prosody, on the function of metre in emphasizing and reinforcing the beauties of thought, emotion, and expression that poetry offers. Two practical illustrations have just been given above. Every writer on poetics, from Aristotle down, has had something to contribute, but the substance of it all may be found in the eighteenth chapter of Coleridge's Biographia Literaria, from which a few sentences have already been quoted.[22] It is not merely that verse by its external appearance notifies the reader, or by its perceptible regularity notifies the listener, that the writer is putting forth his highest efforts, that language is being driven to its highest possibilities; it is not that the use of verse signalizes greater aims and intentions than the use of prose; but rather that the higher efforts, the greater aims, turn by a natural, spontaneous, but partly mysterious instinct to metrical forms for adequate or fit expression. The poets themselves have proved this. No one, barring a few notable exceptions, who felt the creative powers of poetry within him has dared neglect or refuse the added difficulties and the potential beauties of metre. Not the sense of obstacles overcome, but of possibilities realized prompts to formal rhythms. Music, in Dryden's phrase, is inarticulate poetry; but poetry, while it remains articulate and endeavors to accomplish its own destinies, will always approach as close as its own conditions permit to the powers of music. Some poets are inclined more powerfully to music than others. Burns composed with definite melodies in mind; Shelley often began with a little tune which he gradually crystallized into words; Schiller tells us that inspiration often came to him first in the form of music. Tennyson, Swinburne, and others, have chanted rather than read their poetry aloud. And even Browning, who sometimes appears to prefer discord to music, is found to have studied not only the science of music, but also the musical effectiveness of words.
While it is unquestionably going too far to insist as Hegel does that "metre is the first and only condition absolutely demanded by poetry, yea even more necessary than a figurative picturesque diction"; or even to say that the finest poetry is always metrical; still it remains a simple fundamental truth that metre is the natural form of poetic language. The great exceptions to this—the poetic prose of a Sir Thomas Browne, a Pater, a Carlyle, or the free-verse of Whitman—do but prove its soundness; for we always feel them to be something exceptional, something not quite natural though not quite amiss, something wonderful, like tours de force. We would not wish them otherwise, perhaps; but we should doubt them if we did not actually have them before us.
