If, then, we would justly value the half dozen composers who have done most for music in our day, we must add to our understanding of them as persons a knowledge of the general development in which they play a part; we must gain some sense of that great process of musical growth from which they inherit their resources, to which they make their various contributions, and in relation to which alone they can be fairly compared and appreciated. After examining the general course of musical history, ascertaining some fundamental principles, and applying these principles to our special judgments, we shall be able to perceive the greatest musicians of our day in their relations, and to get a perspective view of modern music in which they shall take their proper places. I If we wish to get an idea of primeval music, to see from what impulses it took rise, we have only to study the musical activities of children and savages, in whom we have primeval man made contemporary, the remote past brought conveniently into the present to be observed. When we make such a study we find that both children and savages express their feelings by gestures and cries, that under the sway of emotion they either dance or sing. To them quiet, silent feeling is impossible. Are they joyful, they leap and laugh; are they angry, they strike and shout; are they sad, they rock and moan. Moreover, we can discriminate the kinds of feeling that are expressed by these cries and gestures. Roughly speaking, bodily movement is the natural outlet of active vitality, of the joy of life and the lust of living, while it is the more contemplative emotions--love, grief, reverie, devotion--that find vocal utterance. The war-dances and revels of savages, accompanied by drum and tomtom, are gesticulatory; their love-songs and ululations over the dead are vocal. In the same way children in their moments of enthusiasm are wont to march about shouting and stamping in time, all their limbs galvanized with nervous force; and it is when the wave of energy has passed and they sit on the floor engrossed in blocks or dolls that they sing to themselves their curious undulating chants. Even in ourselves we can observe the same tendencies, checked though they be by counter-impulses in our more complex temperaments: when we are gay we walk briskly, clicking our heels in time and perhaps whistling a catch; in our dreamier hours we are quiet, or merely hum a tune under our breath. Thus through all human nature runs the tendency to vent feeling, active and contemplative, in those bodily movements and vocal utterances which underlie the two great generators of music, dance and song.
