To divide by an arbitrary line something that cannot be divided is a process that is disturbing to some. Perhaps our deductions are not as inevitable as they are logical, which suggests that they are not "logic." An arbitrary assumption is never fair to all any of the time, or to anyone all the time.
Many will resent the abrupt separation that a theory of duality in music suggests and say that these general subdivisions are too closely inter-related to be labeled decisively-"this or that." There is justice in this criticism, but our answer is that it is better to be short on the long than long on the short. In such an abstruse art as music it is easy for one to point to this as substance and to that as manner. Some will hold and it is undeniable-in fact quite obvious-that manner has a great deal to do with the beauty of substance, and that to make a too arbitrary division, or distinction between them, is to interfere, to some extent, with an art's beauty and unity. There is a great deal of truth in this too. But on the other hand, beauty in music is too often confused with something that lets the ears lie back in an easy chair. Many sounds that we are used to, do not bother us, and for that reason, we are inclined to call them beautiful. Frequently,-possibly almost invariably,-analytical and impersonal tests will show, we believe, that when a new or unfamiliar work is accepted as beautiful on its first hearing, its fundamental quality is one that tends to put the mind to sleep. A narcotic is not always unnecessary, but it is seldom a basis of progress,-that is, wholesome evolution in any creative experience. This kind of progress has a great deal to do with beauty-at least in its deeper emotional interests, if not in its moral values. (The above is only a personal impression, but it is based on carefully remembered instances, during a period of about fifteen or twenty years.) Possibly the fondness for individual utterance may throw out a skin-deep arrangement, which is readily accepted as beautiful-formulae that weaken rather than toughen up the musical-muscles. If the composer's sincere conception of his art and of its functions and ideals, coincide to such an extent with these groove-colored permutations of tried out progressions in expediency, that he can arrange them over and over again to his transcendent delight-has he or has he not been drugged with an overdose of habit-forming sounds? And as a result do not the muscles of his clientele become flabbier and flabbier until they give way altogether and find refuge only in a seasoned opera box-where they can see without thinking? And unity is too generally conceived of, or too easily accepted as analogous to form, and form (as analogous) to custom, and custom to habit, and habit may be one of the parents of custom and form, and there are all kinds of parents. Perhaps all unity in art, at its inception, is half-natural and half-artificial but time insists, or at least makes us, or inclines to make us feel that it is all natural. It is easy for us to accept it as such. The "unity of dress" for a man at a ball requires a collar, yet he could dance better without it. Coherence, to a certain extent, must bear some relation to the listener's subconscious perspective. For example, a critic has to listen to a thousand concerts a year, in which there is much repetition, not only of the same pieces, but the same formal relations of tones, cadences, progressions, etc. There is present a certain routine series of image-necessity-stimulants, which he doesn't seem to need until they disappear. Instead of listening to music, he listens around it. And from this subconscious viewpoint, he inclines perhaps more to the thinking about than thinking in music. If he could go into some other line of business for a year or so perhaps his perspective would be more naturally normal. The unity of a sonata movement has long been associated with its form, and to a greater extent than is necessary. A first theme, a development, a second in a related key and its development, the free fantasia, the recapitulation, and so on, and over again. Mr. Richter or Mr. Parker may tell us that all this is natural, for it is based on the classic-song form, but in spite of your teachers a vague feeling sometimes creeps over you that the form-nature of the song has been stretched out into deformity. Some claim for Tchaikowsky that his clarity and coherence of design is unparalleled (or some such word) in works for the orchestra. That depends, it seems to us, on how far repetition is an essential part of clarity and coherence. We know that butter comes from cream-but how long must we watch the "churning arm!" If nature is not enthusiastic about explanation, why should Tschaikowsky be? Beethoven had to churn, to some extent, to make his message carry. He had to pull the ear, hard and in the same place and several times, for the 1790 ear was tougher than the 1890 one. But the "great Russian weeper" might have spared us. To Emerson, "unity and the over-soul, or the common-heart, are synonymous." Unity is at least nearer to these than to solid geometry, though geometry may be all unity.
But to whatever unpleasantness the holding to this theory of duality brings us, we feel that there is a natural law underneath it all, and like all laws of nature, a liberal interpretation is the one nearest the truth. What part of these supplements are opposites? What part of substance is manner? What part of this duality is polarity? These questions though not immaterial may be disregarded, if there be a sincere appreciation (intuition is always sincere) of the "divine" spirit of the thing. Enthusiasm for, and recognition of these higher over these lower values will transform a destructive iconoclasm into creation, and a mere devotion into consecration-a consecration which, like Amphion's music, will raise the Walls of Thebes.
