Yet the appearance of Pan marks only one stage in the land of myth, and that only just within the confines near where the border lines of myth and history meet. For many thousand years beyond this the imagination must travel to reach the earliest sources of music. The complete set of seven pipes claimed by Pan was not the work of a summer’s day, the scale as seven sounds was not the witchery of a nymph’s voice happily remembered by a forest God; no, we may be sure the course of life was more prosaic than that, and the seven-toned instrument had, as a seven branched river, its beginning from one,—one pipe, ages, it may be, earlier than the seven. What do I make of it? Clearly this,—man IS a measuring animal. Like other animals he calculates, forecasts and provides, but he alone possesses the measuring faculty. Rambling again and again through the region of the past, the thought presses forward for recognition that man is a measuring animal, and hence his ability to produce instruments of music. In the beginning they were all founded upon measure, the rude measure of what suited the fingers; and the habit of so marking off spaces, as time went on, recorded itself in a system, at first simple as a child’s wit could compass, and afterwards so growing in complexity as to tax the ingenuity of the most active brains of full-grown civilized men to master and utilize, and yet at the last nothing more than a system of finger activity for the covering of holes and the touching of strings. Thus your musical scales arose. Had Polyphemus had the ordering of a musical scale, most surely the intervals would have been considerably larger; he would have suited his own fingers whether with lengths of strings or with holes in pipes. Imagine yourself a prehistoric man. How would you set about whistling? The lips are in the control of the imitative faculty; the effect called whistling would naturally be first elicited by accident of emotion, or sensibility of one kind or other. The intent to whistle would arise in desire to imitate; a chance whistle heard from a shell or hollow nut or reed would attract attention as for imitation. To imitate, is, as we know, a propensity of monkeydom. How the human animal shares this propensity as a characteristic of his race, and how society is based most differentially upon it,—is not that also taught and recognized in philosophy? Beyond the faculty of imitation man possesses that of measuring; he measures and apportions in his buildings and his bakings: inches and acres bear relation to each other; he marks off spans and cubits and inches, and apportions minutely by millet-seeds and barley-corns. For in earliest times simplest means and methods were as arbitrary as are now our elaborated mechanisms. It is a truism that music is ruled by measure, but what I want you to perceive is quite a different interpretation, and that is that it was the _measuring that ordered the music_.
