In music, then, we find rhythm, order, sequence. It is both episodic and static, though episode and unity are in symbolic form. In the individual sequences, the internal multiplicity, the episode is given; in the whole, the unity of Reality, the static, or better, the absolute element.

Because in good music these two aspects must of necessity be perfectly balanced, music can rouse the keenest, highest sense of beauty in a greater degree than any other of the arts.

But often music falls short of this. Mendelssohn for instance, too often sacrifices everything to prettiness. The individual sequences are trivial and empty. Multiplicity of episode is lost sight of in a rather petty unity; the two are not balanced. The fourth sound is simply a fourth note, not a star. Not only is the intuition limited, but the balance is not preserved between the notes and the whole in its expression. Bach owes his pre-eminence to the perfect balance between attention to detailed sequence and expression of a great intuition. Future musicians may see further than he did, but unless they can achieve his perfect balance they will fail to express what they see, and in so far as they fail they will be rewarded with ugliness.

The music-hall tune has but a very paltry vision to express; generally the relationship it portrays is one of vulgar intrigue or animal desire, at best one of elementary aspiration; and its notes have a purely subordinate and utilitarian rôle. If it is pretty or ingenious it has got far beyond the average. Generally, moreover, it is constrained by considerations alien to music. The words are written, and the tune has to illustrate them. In this it differs from folk-tunes, where words and music grow together, each shaping, moulding, modifying the other, till the song is one thing.

This brings us back to a question which we have several times touched upon, and as often shelved—the question of the overlapping of different arts. Opera, oratorio, and ballet give us excellent examples, and from them we will draw the material of our brief discussion.

In Opera we have drama, episode expressed in language, set in a more or less accordant scene with histrionic accompaniment, and woven in with a musical interpretation. In Oratorio we have the same thing without the scenery and the histrionics. In Ballet—and of this art the Russian Ballet is especially in my mind—we have the drama, the scene, the histrionic accompaniment in choregraphic form, and the music.

Let us take Opera first. There are two appeals to the ear and two to the eye. The music and the words; the acting and the scenery. The scenery, if subdued and perfectly in accord with the action, does not much distract the attention, for it is purely a pictorial setting. Nevertheless a sense is growing that in drama it ought to be so much subordinated that it does not distract the attention at all, being confined to a few patterns that help in our understanding of the motive, or to simple draperies. As far as I am aware this has not yet been attempted in opera[42], but opera is such a jumble of incongruities that it can never be an artistic whole, much as we may rejoice in individual parts of it. The words, however, do constrain the music in a manner thoroughly unjustifiable: “In composing an opera the stage should be the musician’s first thought, he must not abuse the confidence of the theatre-goer who comes to see as well as to hear.... The stage often paralyses a composer’s inspiration, that is why symphonic and chamber music are so far superior to opera. A symphony or a sonata imposes no limitations, but in opera, the first necessity is to speak the musical language of the great public[43].” Moreover the action and the music are so incompatible that we are forced to leave our sense of humour outside the theatre door. When the hero explains for ten minutes that the heroine is in acute danger and that therefore he must hurry away; when Tristan and Isolde sing their passion with complete detachment for more than half an hour; we cannot feel that the action helps the music or the music the action. In Oratorio, since action is absent, we feel this particular incongruity less, for we manage mentally to eliminate time; but few will be found to defend the oratorio as a form of aesthetic expression. It is the anthem prolonged into a “useless Alexandrine,” “which like a wounded snake drags its slow length along.” The fatal fact about opera and oratorio is that the music is constrained to do something that is alien to itself. It is interpretive of episode, and the episode forces it into shape. It is not free. This is the root trouble always when two arts overlap. Art must be completely free to express its intuition technically, subject only to the inevitable restrictions of the technique proper to it. From these restrictions it even gains, since the lines of simplification are to some extent determined, and this very determination helps the artist towards clear expression of a clear intuition. It would, of course, be absurd to say that music does not express definite intuitions that are expressible through other media as well. “I do not in the least agree with you that music cannot interpret the universal nature of love,” writes Tchaikovsky to Nadejda von Meck. “On the contrary, I think only music is capable of doing so. You say words are necessary. O no! This is just where words are not needed, and where they have no power; a more eloquent language comes in, which is music. Look at the poetical forms to which poets have recourse in order to sing of love; they simply usurp the spheres which belong inseparably to music. Words clothed in poetical forms cease to be mere words; they become partly music[44].” But if there is a restriction alien to the art and imposed from without, which prevents full expression in that medium, the result is bound to be more or less a failure. The dramatic episode and the verbal form in opera constitute such a restriction, introducing a vein of unreality that is fatal to aesthetic expression. In oratorio, where the words demand a representation they do not get, and where yet the music is bound by the words, we feel the same thing. Even to take a poem and set it to music is almost bound to lead to aesthetic disappointment. The intuition of the artist is not single nor free. The writer of the melody may recreate the intuition of the poet, he may try to express the same intuition in his setting, but the setting is none the less constrained by the words. The musician is not at liberty to form one clear intuition and give it free play[45]. The form of the expression is already fixed in part, and the knowledge of this fixation forms a second intuition which generally obscures and confuses the main one. Moreover both expressions appeal to the same sense, that of hearing, and this, apparently, produces greater confusion, more lack of clarity, in the auditor. The same fact accounts for the unsatisfactoriness of music which moves out of its proper sphere and endeavours to tell a definite story or paint a definite scene. The 1812 Overture, fine though it is, can never be said to be pre-eminent as music; nor can Haydn’s Creation, nor any of the music that, intentionally or unintentionally, is not single-hearted, but calls up visual images as well as depending on them. This statement does not constitute an indictment of programme-music. The Adagio of Beethoven’s Fourth Symphony cannot be thus lightly dismissed[46]. In Tchaikovsky’s introspective letters we find most interesting accounts of the inspiration from which he worked, and an eloquent defence of programme-music in general, and his own Fourth Symphony in particular[47]. To N. F. von Meck he writes[48]: “Laroche is entirely opposed to a programme. He thinks the composer should leave the hearer to interpret the meaning of the work as he pleases; that the programme limits his freedom; that music is incapable of expressing the concrete phenomena of the physical and mental world.... If you care to hear my opinion on the subject, I will give it in a few words.... I think the inspiration of a symphonic work can be of two kinds: subjective or objective. In the first instance it expresses the personal emotion of joy or sorrow, as when a lyric poet lets his soul flow out in verse. Here a programme is not only unnecessary, but impossible. It is very different when the composer’s inspiration is stirred by the perusal of some poem, or by the sight of a fine landscape, and he endeavours to express his impressions in musical forms. In this case a programme is indispensable.... To my mind, both kinds of music have their raison d’être, and I cannot understand those who will only admit one of these styles. Of course every subject is not equally suitable for a symphony, any more than for an opera; but, all the same, programme-music can and must exist. Who would insist, in literature, upon ignoring the epic and admitting only the lyric element?”

Tchaikovsky seems to me to ignore the deepest side of music, however; that intuition of an ordered, universal harmony which gives to Bach his pre-eminence. Programme-music, then, is not necessarily limited to any great extent by that which it represents, provided the representation is sufficiently generalised to allow the music free scope. But it is always in danger of losing touch with the universal in over-emphasis of the particular, becoming constrained by its subject. Moreover it loses something of the freedom, and independence of phenomenal existence, which is the peculiar privilege of music and its unique prerogative among the arts, taking on something that belongs to painting or language. In so far as the wrong technical medium is used, just so far aesthetic expression fails.

These strictures do not apparently apply, at any rate in the same degree, where two media appealing to two different senses are used simultaneously. We are accustomed to correlate sight and hearing and to form through them a single intuition. This may explain the extraordinary satisfyingness of the Russian Ballet, in spite of its frequent artificiality and the perverted themes and imagery that pass unnoticed by the more healthy-minded public of England. The episodic side, made rhythmical and ordered in its choregraphic presentation, parallels, but does not constrain in any great degree, the musical side. In Les Sylphides especially the same intuition is expressed in two media. The choregraphic artist has studied and followed out the intuition of Chopin, and has expressed it in a different medium. But music and dancing have much ground in common, and consequently both are capable of serving as the technical medium for one or the same intuition. Therefore Les Sylphides[49] is more of an artistic whole than almost any other compound aesthetic expression. Art must be free, and if it use two media, both must express the same intuition—this is the root of the matter. You may appeal simultaneously to two senses, but you must do so in the medium proper to each sense and the intuition must be capable of expression in those media. To appeal to one sense through the medium proper to another is to court disaster. We see that this must be so if, as is the case, the aesthetic intuition has to be founded on the particular before it can move out to discover the universal; and the particular cannot be faithfully represented if the representation is not as clear-cut as the intuition and the reality intuited. Art must be free, for it is the intuition of a relation free on one side at least, and not finally satisfied till it finds rest in mutuality, love, free on both sides. It is the expression of our growing understanding of the meaning of Reality.

No doubt music, like all other arts, has been transformed from its original character. It is no longer imitative, though it may have been first roused by imitative attempts; it is no longer dependent on the harmony of bodily well-being, though it may first have expressed such harmony. In it spirit calls to spirit, no longer body to body. But this need not surprise us. The foundations contribute nothing to the beauty of a building, though upon them the building is reared. All that is greatest in man had a very humble beginning. Even his limbs and lungs had a plebeian ancestry.
