The Principles of English Versification

by Paull F. Baum

Rhythm, in its simplest sense, is measured motion; but by various natural extensions of meaning the word has come to be used almost as a synonym of regularity of variation. Whatever changes or alternates according to a recognizable system is said to be rhythmic, to possess rhythm. In this sense, rhythm is one of the universal principles of nature. We find it in the stripes of the zebra, the indentation of leaves, the series of teeth or of crystals, the curves of the horizon; in the tides, the phases of the moon, the rising and setting of the sun, the recurrence of seasons, the revolutions of planets; in the vibrations of color, sound, and heat; in breathing, the throbbing of the pulse, the stride of walking. All action and reaction whatever is rhythmic, both in nature and in man. "Rhythm is the rule with Nature," said Tyndall; "she abhors uniformity more than she does a vacuum." So deep-rooted, in truth, is this principle, that we imagine it and feel it where it does not exist, as in the clicking of a typewriter. Thus there is both an objective rhythm, which actually exists as rhythm, and a subjective rhythm, which is only the feeling of regularity resulting from a natural tendency of the mind to 'organize' any irregularity that we meet.

There are two fundamental forms of rhythm, though these are not altogether mutually exclusive, (1) spatial, and (2) temporal.

Spatial Rhythms. The simplest spatial rhythm is a series of equidistant points—

More complex forms are the succession of repeated designs in mouldings and wainscotings (for example, the alternation of egg and dart), the series of windows in a wall, or of the columns of a Greek temple, or of the black and white keys of a piano. Still more complex is the balanced arrangement of straight lines and curves in a geometrical design, as in certain Oriental rugs or the Gothic rose windows. And probably the most complex spatial rhythms are those of the facades of great buildings like the Gothic cathedrals or St. Mark's of Venice, where only the trained eye perceives the subtleties of alternation and balance.

Temporal Rhythms. Temporal rhythms, apart from those of planetary motion, the alternation of seasons, and the like (which are called rhythmic by a metaphorical extension of the term), manifest themselves to us as phenomena of sound; hence the two concepts time-rhythm and sound-rhythm are commonly thought of as one and the same.

The simplest form is the tick-tick-tick of a watch or metronome. But such mechanical regularity is comparatively rare, and in general the temporal rhythms are all highly complex composites of sounds and silences. Their highest manifestations are music and language. The rhythm of language, and a fortiori that of verse, is therefore primarily a temporal or sound rhythm, and as such is the particular subject of the following pages.

Combinations. Language, however, when addressed to the eye rather than to the ear, that is, when written or printed rather than spoken, is partly a spatial phenomenon; and, as will appear presently, the arrangement of words and sentences on the formal page is a real factor in the rhythm of verse. Moreover, most of the rhythms of motion, such as walking, the ebb and flow of tides, the breaking of waves on the beach, are composites of temporal and spatial.[1]

Sound Rhythm. These elementary generalizations must be narrowed now to the special phenomena of sound, and then still more particularly to the sounds of language.
