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.
Such activities, however, are by no means as yet dance and song. At first they are no more than mere reflex actions, as spontaneous and unthinking as the «Ow» of the man who stubs his toe. The emotion is felt, and out comes the gesture or cry; that is all. It is the organism's way of letting off steam. It is not expression, not being prompted by a desire to communicate the feeling, but merely by the impulse to be unburdened of it. Before there can be true expression or communication, there must be two more links added to the chain of which these automatic activities are only the first. The second link is imitation. According to a theory widely exploited in recent years, we tend to imitate whatever we see another do. With children the tendency is so strong that a large part of their time and energy is devoted to elaborate impersonation and make-believe, and the entire basis of their education is acquired through this directly assimilative faculty. In adults it is less active, but every sensitive person knows how difficult it is not to imitate foreign accents, stammering, and other petty mannerisms, and few are so callous that they can withstand the infection of strong stimuli like the gestures and cries of emotion. The wailing baby in the street car, who moves all the other babies within hearing to wail also (if they be not already at it independently); the dog baying the moon until all within earshot join in the serenade; the negro at the camp-meeting clapping his hands until the whole company is in a rhythmic ecstasy—these are examples of the contagion of cries and gestures. Bearing them in mind, it is easy to see that the vocal or bodily acts which in the first place are mere reflexes of feeling, performed with no thought of expression, but only for personal easement, will generally, nevertheless, prompt similar acts in others. The performances of the individual will not end with himself; thanks to the instinct of imitation, they will be very widely copied.
But now—and this is the third link of the chain—bodily acts set up mental states, and a man cannot gesticulate or vocalize without feeling the emotions of which his actions are, as we say, expressive. «We feel sorry because we cry,» writes Professor William James in his brilliant, paradoxical way, «angry because we strike, afraid because we tremble;» and whether or not we agree with his extreme view that the mental state is entirely a reverberation of bodily disturbances, we cannot but realize that in all these cases executing the expression tends to give us the feeling. He who persistently smiles will end by being cheerful, and a moderate amount of sighing or groaning will make any one melancholy. Above all, the imitation of vocal movements, such as we all go through at least incipiently when we hear melody, and the «keeping time» that strong dance-music so irresistibly prompts—these actions very noticeably set up in us their appropriate states of feeling. We not only imitate the lip motions and throat contractions of a persuasive speaker or singer, but doing so fills us with the emotion that prompts his utterance. Tired soldiers not only step out to a potently rhythmical tune—that is, they not only imitate the beat—but they actually feel less weary, more energetic, so long as the stimulus lasts. Once a bodily activity is set up, no matter how, it arouses the mental state proper to it; in a word, expression generates emotion.
Obviously, then, if in the first place the natural outlets of emotional excitement are bodily motions and vocal sounds, if in the second place the observation of such motions and sounds arouses the impulse to imitate them, and if finally this imitation produces again in the imitator the states of mind which first set the whole process going, then these motions and sounds, these inchoate germs of dance and song, possess an enormous latent power of expression, and need only to be systematized to become a wonderfully eloquent language. Such a language, in fact, is music.
