THERE is a story, in Max Muller's amusing reminiscences, of how Mendelssohn and David once played, in his hearing, Beethoven's later sonatas for piano and violin, and of how they shrugged their shoulders, and opined the old man had not been quite himself when he wrote them. In the history of music it seems to be a rule almost without exceptions, that the works of genius are greeted with contumely. The same is no doubt true, though to a much less degree, of other arts, but in music it seems that the critics proposed also excellent reasons for their vehemence.

And it is instructive to observe that the objections, and the reasons for the objections, recur, after the original object of wrath has passed into acceptance, nay, into dominance of the musical world. One may also descry one basic controversy running through all these utterances, even when not explicitly set forth.

It was made a reproach to Beethoven, as it has been made a reproach to Richard Strauss, that he sacrificed the beauty of form to expression; and it was rejoined, perhaps less in the old time than now, that expression was itself the end and meaning of music. Now the works of genius, as we have seen, after all take care of themselves. But it is of greatest significance for the theory of music, as of all art, that in the circle of the years, the same contrasting views, grown to ever sharper opposition, still greet the appearance of new work. It was with Wagner, as all the world knows, that the question came first to complete formulation. His invention of the music-drama rested on his famous theory of music as the heightened medium of expression, glorified speech, which accordingly demands freedom to follow all the varying nuances of feeling and emotion. Music has always been called the language of the emotions, but Wagner based his views not only on the popular notion, but on the metaphysical theories of Schopenhauer; in particular, on the view that music is the objectification of the will. Herbert Spencer followed with the thesis that music has its essential source in the cadences of emotional speech. In opposition primarily to Wagner, the so-called formalists were represented by Hanslick, who wrote his well-known "The Beautiful in Music" to show that though music ha a limited capacity of expression, its aim is formal or logical perfection alone. The expressionist school could not contradict the undoubted fact that chords and intervals which are harmonious show certain definite physical and mathematical relationships, that, in other words, our musical preferences appear to be closely related to, if not determined by, these relationships. Thus each school seemed to be backed by science. The emotional-speech theory has been held in a vague way, indeed, by most of those theorists whose natural conservatism would have drawn them in the other direction, and is doubtless responsible for the attempts at mediation, first made by Ambros,<1> and now met in almost all musical literature. Music may be, and is, expressive, it is said, so long as each detail allows itself to be entirely derived from and justified by the mere formal element. The "centre of gravity" lies in the formal relations.

<1> The Boundaries of Music and Poetry.

To this, after all, Hanslick himself might subscribe. Other writers seek to balance form and expression, insisting on "the dual nature of music," while resting ultimately on the emotional-speech theory. "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."<1>

<1> D.G. Mason, From Grieg to Brahms, 1902, p. 30.

This usual type of reconciliation, however, is a perfectly mechanical binding together of two possibly conflicting aesthetic demands. The question is of the essential nature of music, not whether music may be, but whether it must be, expressive; not whether is has expressive power, but whether it is, in its essence, expression,-a question which is only obscured by insisting on the interdependence of the two elements. If music has its essential source in the cadences of speech, then it must develop and must be judged accordingly. Herbert Spencer is perfectly logical in saying "It may be shown that music is but an idealization of the natural language of emotion, and that, consequently, music must be good or bad according as it conforms to the laws of this natural language."<1> But what, then, of music which, according to Ambros, is justified by its formal relations? Is music good because it is very expressive, and bad because it is too little expressive? or is its goodness and badness independent of its expressiveness? Such a question is not to be answered by recognizing two kinds of goodness. Only by an attempt to decide the fundamental nature of the musical experience, and an adjustment of the other factors in strict subordination to it, can the general principle be settled.

<1> On Educaiton, p. 41.

The excuse for this artificial yoking together of two opposing principles is apparent when it is seen that form and expression are taken as addressing themselves to two different mental faculties. It seems to be the view of most musical theorists that the experience of musical form is a perception, while the experience of musical expression, disregarding for the moment the suggestion of facts and ideas, is an emotion. Thus Mr. Mason: "In music we are capable of learning, and knowledge of the principles of musical effect can help us to learn, that the balance and proportion and symmetry of the whole is far more essential than any poignancy, however great, in the parts. He best appreciates music...who understands it intellectually as well as feels it emotionally;"<1> and again, "We feel in the music of Haydn its lack of emotional depth, and its lack of intellectual subtlety."

<1> Op. Cit., p. 6.

It is just this contrast and parallelism of structure as balance, proportion, symmetry, addressed to the mind, with expression as emotional content, that a true view of the aesthetic experience would lead us to challenge. If there is one thing that our study of the general nature of aesthetic experience has shown, it is that aesthetic emotion is unique- neither a perception nor an intellectual grasp of relations, nor an emotion within the accepted rubric-joy, desire, triumph, etc. Whether or not music is an exception to this principle, remains to be seen; but the presumption is at least in favor of a direct, immediate, unique emotion aroused by the true beauty of music, whatever that may prove to be.

With a great literature in the form of special studies, we must yet, on the whole, admit that we possess no general formula in the philosophy or psychology of music which covers the whole ground. Schopenhauer has said that music is the objectification of the will-not a copy or a picture of it, but the will itself; a doctrine which however illuminating when it is modified in various ways is obviously no explanation of our experience. Hanslick has but shown what music is not; Edmund Gurney's eloquent book, "The Power of Sound," is completely agnostic in its conclusion that music is a unique, indefinable, indescribable phenomenon, which possesses, indeed, certain analogues with other physical and psychical facts, but is coextensive with none. Spencer's theory of music as glorified speech is not only in a yet unexplained conflict with many facts, but has never been formulated so that it could apply to concrete cases. The same is true of Wagner's "music as the utterance of feeling."

But there is a body of scientific facts respecting the elements of music, in which we may well seek for clues. As facts alone they are of no value. They must be explained as completely as possible; and it is probable that if we are able to reach the ultimate nature and origin of these elements of music they will prove significant, and a way will be opened to a theory of the whole musical experience. The need of such intensive understanding must excuse the more or less technical discussions in the following pages, without which no firm foundation for a theory of music could be attained.
