Pitch. Pitch appears to be sometimes a determining element in rhythm, as has been shown above; but since its chief function in verse is that of supporting the recognized determinants and adding grace-notes to the music, it is omitted here and discussed in Chapter V, below.
Balance of Forces. It is not to be inferred from the foregoing sections that the basis of English metre is time. For the basis of English metre is dual: time and stress are inextricable. Beneath all metrical language runs the invisible current of time, but the surface is marked by stress. The warp of the metrical fabric is time; stress is the woof. And from the surface, of course, only the woof is visible. Moreover, the poet's point of view in composing and generally the reader's point of view in reading has always been that of the 'stresser.' No poet ever wrote to a metronome accompaniment; extremely few readers are fully conscious—few can be, from the nature of our human sense of time—of the temporal rhythm that underlies verse. Thus it has come about, historically, that modern English verse is written and regarded as a matter of stress only, because to the superficial view stress is predominant.[32] Probably the truth is that most poets compose verse with the ideal metrical scheme definitely in mind and trust (as they well may) to their rhythmical instinct for the rest. Whatever device they employ for keeping the pattern always before them, they do keep it distinctly before them—except perhaps in the simpler measures which run easily in the ear—and build from it as from a scaffolding. They may not know and may not need to know that this metrical scheme does itself involve equal time units as well as equal stresses. They vary and modulate both time and stress according to the thought and feeling the words are asked to express. And though it is a point on which no one can have a dogmatic opinion, one inclines to the belief that usually the finest adaptations of ideas and words to metre are spontaneous and intuitive. Skill is the result of habit and training, and metrical skill like any other; but there is also the faculty divine. One is suspicious of the

It would be absurd to imagine a prosody which was independent of its own materials. It would be absurd therefore not to find in all language the elements out of which verse is made. Indeed, M. Jourdain, having recovered from his first shock on learning that he had actually been talking prose, must prepare for a second: that he has actually been talking potential verse. The three acoustic properties of speech—duration, intensity, pitch—modified by the logical and emotional content of which the sounds are symbolic, combine to produce an incredibly subtle and elastic medium which the poet moulds to his metrical form. In this process of moulding and adjustment, each element, under the poet's deft handling, yields somewhat to the other, the natural rhythm of language and the formal rhythm of metre; and the result is a delicate, exquisite compromise. When we attempt to analyze it, its finer secrets defy us, but the chief fundamental principles we can discover, and their more significant manifestations we can isolate and learn to know. In all the arts there is a point at which technique merges with idea and conceals the heart of its mystery. The greatest poetry is not always clearly dependent upon metrical power, but it is rarely divorced from it. No one would venture to say how much the metre has to do with the beauty of the
