"Cannon to right of them, cannon to left of them."
If a line is felt as "metrical," i.e. divided into approximately equal time-intervals, the particular label employed to indicate the nature of the metre is unimportant. It may be left to the choice of each student of metre, provided he uses his terms consistently. The use of the traditional terminology "iambic," "trochaic," etc., is convenient, and is open to no objection if one is careful to make clear the sense in which he employs such ambiguous terms.
It should also be added, as a means of reconciling the apparently warring claims of stress and quantity in English poetry, that recent investigations in recording through delicate instruments the actual time-intervals used by different persons in reading aloud the same lines of poetry, prove what has long been suspected, namely, the close affiliation of quantity with stress. [Footnote: "Syllabic Quantity in English Verse," by Ada F. Snell, Pub. Of Mod, Lang. Ass., September, 1918.] Miss Snell's experiments show that the foot in English verse is made up of syllables 90 per cent of which are, in the stressed position, longer than those in the unstressed. The average relation of short to long syllables, is, in spite of a good deal of variation among the individual readers, almost precisely as 2 to 4—which has always been the accepted ratio for the relation of short to long syllables in Greek and Roman verse. If one examines English words in a dictionary, the quantities of the syllables are certainly not "fixed" as they are in Greek and Latin, but the moment one begins to read a passage of English poetry aloud, and becomes conscious of its underlying type of rhythm, he fits elastic units of "feet" into the steadily flowing or pulsing intervals of time. The "foot" becomes, as it were, a rubber link in a moving bicycle chain. The revolutions of the chain mark the rhythm; and the stressed or unstressed or lightly stressed syllables in each "link" or foot, accommodate themselves, by almost unperceived expansion and contraction, to the rhythmic beat of the passage as a whole.
Nor should it be forgotten that the "sense" of words, their meaning-weight, their rhetorical value in certain phrases, constantly affects the theoretical number of stresses belonging to a given line. In blank verse, for instance, the theoretical five chief stresses are often but three or four in actual practice, lighter stresses taking their place in order to avoid a pounding monotony, and conversely, as in Milton's famous line,
"Rocks, caves, lakes, dens, bogs, fens, and shades of death,"
the rhetorical significance of the monosyllables compels an overloading of stresses which heightens the desired poetic effect. Corson's Primer of English Verse and Mayor's English Metres give numerous examples from the blank verse of Milton and Tennyson to illustrate the constant substitution and shifting of stresses in order to secure variety of music and suggestive adaptations of sound to sense. It is well known that Shakspere's blank verse, as he developed in command of his artistic resources, shows fewer "end-stopped" lines and more "run-on" lines, with an increasing proportion of light and weak endings. But the same principle applies to every type of English rhythm. As soon as the dominant beat—which is commonly, but not always, apparent in the opening measures of the poem—once asserts itself, the poet's mastery of technique is revealed through his skill in satisfying the ear with a verbal music which is never absolutely identical in its time-intervals, its stresses or its pitch, with the fixed, wooden pattern of the rhythm he is using.
For the human voice utters syllables which vary their duration, stress and pitch with each reader. Photographs of voice-waves, as printed by Verrier, Scripture, and many other laboratory workers, show how great is the difference between individuals in the intervals covered by the upward and downward slides or "inflections" which indicate doubt or affirmation. And these "rising" and "falling" and "circumflex" and "suspended" inflections, which make up what is called "pitch-accent," are constantly varied, like the duration and stress of syllables, by the emotions evoked in reading. Words, phrases, lines and stanzas become colored with emotional overtones due to the feeling of the instant. Poetry read aloud as something sensuous and passionate cannot possibly conform exactly to a set mechanical pattern of rhythm and metre. Yet the hand-woven Oriental rug, though lacking the geometrical accuracy of a rug made by machinery, reveals a more vital and intimate beauty of design and execution. Many well-known poets—Tennyson being perhaps the most familiar example—have read aloud their own verses with a peculiar chanting sing-song which seemed to over-emphasize the fundamental rhythm. But who shall correct them? And who is entitled to say that a line like Swinburne's
"Full-sailed, wide-winged, poised softly forever asway"
is irregular according to the foot-rule of traditional prosody, when it is probable, as Mr. C. E. Russell maintains, that Swinburne was here composing in purely musical and not prosodical rhythm? [Footnote: "Swinburne and Music," by Charles E. Russell, North American Review, November, 1907. See the quotation in the "Notes and Illustrations" for this chapter.]
Is it not true, furthermore, as some metrical sceptics like to remind us, that if we once admit the principle of substitution and equivalence, of hypermetrical and truncated syllables, of pauses taking the place of syllables, we can very often make one metre seem very much like another? The question of calling a given group of lines "iambic" or "trochaic," for instance, can be made quite arbitrary, depending upon where you begin to count syllables. "Iambic" with initial truncation or "trochaic" with final truncation? Tweedle-dum or tweedle-dee? Do you count waves from crest to crest or from hollow to hollow? When you count the links in a bicycle chain, do you begin with the slender middle of each link or with one of the swelling ends? So is it with this "iambic" and "trochaic" matter. Professor Alden, in a suggestive pamphlet, [Footnote: "The Mental Side of Metrical Form," already cited.] confesses that these contrasting concepts of rising and falling metre are nothing more than concepts, alterable at will.
