Form in music, however, notwithstanding its origin as a means of defining those emotional expressions which without it would have remained vague, unimitable, and immemorable, is much more than a means of definition. At first practiced as a means to an end, it soon became an end in itself. For the perception of relations, the mental activity which groups impressions, is not merely useful; it is profoundly, indescribably delightful. Calling the mind into activity just as sensation calls the senses, it is a far deeper source of pleasure than sensation can ever be, because the mind far exceeds the senses in the subtlety, variety and independence of its action. When, therefore, the primitive musicians first made their syntheses of gestures and cries they discovered a novel pleasure, altogether more delicious than the crude joys of sensation and expression. Before they made such syntheses they had merely enjoyed the sweetness of tones, and taken satisfaction in expressing their feelings; but when once they learned to group their expressive tones together, to feel the subtle bonds which bound them into clear and salient unity, then they felt a joy altogether new and on a higher plane, they felt true æsthetic delight. Here was not merely a passive, or at most an automatic process; here was a truly creative activity, a conscious and free manipulation of materials. Mere hearing, however delicious, mere expression, however grateful, could not give this sense of mastery, of comprehension, of insight. Beauty alone, beauty depending on consciously made comparisons and contrasts, can give the highest æsthetic delight, the delight in form. And so, like painters who, using form at first to define their material, come quickly to a realization of its inherent value, and finally, if they be true artists, value its pure beauties of line and balance and composition more highly than any mere richness of color or of expression, musicians, in the degree of their true musicianship, came to prize the intrinsic beauty of music above all its other qualities.
Sometimes, doubtless, they carried their devotion too far. In certain periods and individuals the love of formal beauty has entirely eclipsed pleasure in expression. Unable to attend at once to expression and to beauty, many composers, and in some periods all, have devoted their entire energy to the quest for formal perfection. Thus in the work of the Netherland masters of early counterpoint, in some of Bach's ingenious weavings, and in much of the music of Haydn and his contemporaries, the search for purely plastic qualities goes on with little thought of the original emotional burden of the material that is being formulated. To such men form was much more than a means of defining expression; it was an end in itself, and an end worth a lifetime of painstaking, devoted effort.
And yet, justifiable as their feeling was, indispensable as their labors were to that development without which the expressive power of music would itself have remained rudimentary, it is not to their view, but to a more universal one, that we must look to find a rounded theory of expression and form. If it be a mistake to neglect the latter for the former, as they well saw, it is equally a mistake to prize form with too exclusive an enthusiasm. For beauty is itself one of the most potent means of expression. Our minds are not made up of hermetic compartments, but are so permeable, so conductive, that an eloquent thing is made more eloquent by being also beautiful. The impression of beauty reverberates endlessly, intensifying all that is associated with it. The general atmosphere transfigures every feature. If the whole is fair, no detail will be entirely without its appeal to our kindled imaginations, but if the whole is formless, no single phrase, however impassioned, can affect us very deeply. The truth is, then, that form and expression in music are as essential to each other as objects and light in the world of vision. No radiance of illumination will satisfy the eye if there is nothing to see, and, on the other hand, the loveliest things will give little pleasure in the dark. To be beautiful they must be suffused in light. Similarly the phrases of music, to be truly moving, must be suffused in beauty. The greatest masters clearly realized this. Bach in his masterpieces, Beethoven nearly always, and Brahms in his inspired hours, acted on the principle that the two elements must exist side by side, subtly and potently reacting upon each other. Their practice, indeed, unanimously confirms the theory of musical effect which has now been briefly sketched, and which may be more briefly summarized before we pass on to deduce from it some general canons of appreciation and criticism.
Music, we have seen, originates in the spontaneous gestures and cries made by primitive man under the sway of emotion, imitated by observers, and arousing in them the same feelings. As intelligence dawns, men see that this triple process of spontaneous action, imitation and reduplicated feeling affords a basis for a language of emotion, a language that needs, however, to be somehow defined and articulated. Articulation gradually follows by means of the grouping in time which develops the gestures of active feeling into Dance, and the grouping in pitch which develops the utterances of contemplative feeling into Song. Eventually the two modes of grouping are combined, and music becomes an independent art. Meanwhile, the forms at first adopted for the sake of mere definition become the basis of a new and deeper delight, æsthetic beauty, which is sought for both as ancillary to expression and for itself alone. Finally, beauty of form reacts potently on eloquence of expression, and the most universal composers, recognizing the interdependence of the two elements, produce the highest type of pure music, music in which beauty is based upon expression and expression transfigured by beauty.
