(αα) Of these music is furthest removed from sculpture; and this is not merely so in respect to material and type of configuration, but also in that of the completed coalescence of its ideal and external aspects. There is in short a closer affinity between painting and music. In part this is due to the predominant ideality of expression exemplified in both; in part it is referable to treatment of material, in which, as we have already seen, it is permissible for the art of painting to approach the very boundary of music itself. Painting has, however, for its aim in common with sculpture the representation of an objective form in Space, and is restricted in its material to the actual form of things already present outside the sphere of art. It is unquestionably true that neither in the case of the painter nor the sculptor do we accept a human countenance, a position of the human body, the outlines of a mountain, the leafage of a tree precisely in the forms they present to us as here or there in Nature; in both cases we are bound to justify what we have before us under the conditions of the art in question, to adapt it to a particular situation, no less than to employ it as a means of expressing the inevitable artistic result of the entire content of the work. We have, therefore, in both cases on the one hand an independently recognized content, which has to receive artistic individualization, and, on the other, we are confronted with the forms of Nature as they are similarly presented in isolation; and the artist is bound, if he be truly an artist, and seek to unite these two sources of inspiration in his composition, to discover in both the material and support[393] for his conception and execution. In short, he will, acting in the first instance on the security of such general principles[394], endeavour on the one hand to fill out with more concrete detail the generality of his imaginative idea, and on the other to idealize and spiritualize the human or any other of the forms of Nature, which are submitted to serve him as particular models. The musician, on the contrary, it is true, does not abstract from all and every content, but finds the same in a text, which he sets to music, or with absolute freedom gives musical utterance to some definite mood in the form of a theme, which he proceeds to elaborate. The actual region, however, of his compositions remains the more formal ideality, in other words pure tones, and his absorption of content becomes rather a retreat into the free life of his own soul, a voyage of discovery into that, and in many departments of music even a confirmation, that he as artist is free of the content. If we are in a general way permitted to regard human activity in the realm of the beautiful as a liberation of the soul, as a release from constraint and restriction, in short to consider that art does actually alleviate the most overpowering and tragic catastrophies[395] by means of the creations it offers to our contemplation and enjoyment, it is the art of music which conducts us to the final summit of that ascent to freedom. Or in other language that which the plastic arts secure through the objective fact of a plastic beauty, which displays the entirety of human life, human nature as such, its universal and ideal significance, in the detail of its particularity, without losing that essential harmony, this effect music must produce in a wholly different manner. The plastic artist need only exhibit, in that which is enclosed in the conception, what was already therein from the first, so that every detail in its essential determinacy is merely a closer explication of the totality which already floats before the mind in virtue of the content which is there to exhibit it. A figure, for example, in a plastic work of art, requires in this or that situation a body, hands, feet, bust, a head with a given expression, a given pose, other figures, or other aspects to which it is related as a whole, etc., and all these aspects presuppose the others, in making collectively essentially complete work. The elaboration of the theme is in such a case merely a more accurate analysis of that which already itself essentially contains it, and the more elaborate the picture is, which thereby confronts us, the more concentrated is the unity, and the stronger becomes the connection of the parts. The most consummate expression of detail must be, if the work of art is the best class, at the same time an elucidation of the highest form of unity. No doubt the ideal articulation and rounding off in a whole, in which the one part follows inevitably from another, ought to be present in a musical composition. But in some measure the execution here is of a totally different type, and moreover we can only accept the unity in a restricted sense.
(ββ) In a musical theme the significance which has to be expressed is already exhausted[396]. If it is repeated or carried on to further oppositions and mediations these repetitions, modulations, and elaborations by means of other scales may very readily appear superfluous, and rather are appertinent to the purely musical development and the assimilation of the varied content of harmonic progressions which are neither demanded by the content itself[397], nor remain dependent upon it, whereas in the plastic arts the execution of the detail and the passage to it is simply and always a more accurate exhibition and analysis of the content itself.
But of course it is impossible to deny that another theme is actually motived by the way a theme is developed, and each of them, then, in their alternation or their interfusion progress, change, are at one time suppressed, at another emphasized, and by their victory or defeat are able to make a content explicit in its more definite features, oppositions, transitions, developments, and resolutions. But in this case, too, the unity is not made more profound and concentrated by virtue of such elaboration as is the case in sculpture and painting, but is rather an expansion, an extension, a correlative series[398], an addition of remoteness or a return, for which the content, which is thus expressed, remains no doubt the universal centrum, yet does not keep the whole so securely together as we find it is possible to do in the plastic arts, particularly where their subject-matter is confined to the human organism.
(γγ) Looked at from this point of view the art of music, as contrasted with the other arts, lies too close to the medium of that formal freedom of soul life, and thereby cannot fail to a greater or less degree to be diverted beyond what is actually presented, in other words the content[399]. The recollection of a theme proposed is likewise a self-revealment[400] of the artist, in other words is an ideal realization, to the effect that this self is the artist, and he may progress just as he likes, and by what by-paths he likes. But on the other hand the free exercise of imaginative caprice of the above description is expressly to be distinguished from a musical composition which is essentially conclusive, that is to say, which constitutes a fundamentally self-integrated totality. In the free improvization[401] the absence of restrictions is itself an object, so that the artist is able to assert his caprice in the acceptance of any material he chooses, to interweave acknowledged melodies and motives in his improvized productions, to emphasize some new aspect of such, to elaborate them in a variety of modifications, or make them steps in his progression to other material, and advance from thence in the same way to developments of still more arresting contrasts.
In general, however, a musical composition determines the freedom of the composer, either by limiting it to a more self-contained execution, and the observance of what we may describe as a more plastic unity, or by permitting him with the full force of his personality and caprice to pass at every point into more or less important digressions, to let spontaneous ideas travel hither and thither as they please, to lay stress for the moment on this or that motive, and then once more to drown it in an overwhelming torrent. While, then, the study of Nature's forms is essential to both painter and sculptor, the art of music can look for no such fixed body of fact outside its own prescribed forms, with which it would be forced to comply. The extent of the regularity and necessity of its formal character is almost wholly determined within the sphere of tone itself, which does not come into so close an association[402] with the definition of the content that is therein reposed, and consequently in respect to deviations beyond the same permits for the most part a considerable opportunity for the free play of the characteristic impulse of the composer.
And this is the main point of view, from which we may contract music with the strictly plastic arts.
(γ) Looked at from another aspect music is, in the third place[403], most nearly affiliated to poetry; both in fact make use of the same sensuous medium, that is, tone. Despite this, however, these arts are very strongly distinct from one another not only in virtue of the mode of treating tones in each case, but also in respect to their different modes of expression.
(αα) In poetry, as we have found already in our general differentiation of the several arts, tone is not as such elicited and artistically produced by various humanly constructed instruments, but the articulate sound of the human organ of speech is reduced to the mere symbol of speech, retaining thereby nothing more than the value of a sign of ideas, which is by itself devoid of significance. Consequently we find here that tone remains throughout a self-subsistent sensuous entity, which, as the mere symbol of emotions, ideas, and thoughts, possesses the externality and objectivity which is inherent in itself simply in virtue of the fact that is a sign and nothing more. For the true objectivity of the soul-life as such does not consist in utterance and words, but in this fact, that I, as subject, am aware of a thought, a feeling, and so forth, that further I confront it as an object, and in this way have it present to the imagination, or forthwith develop for myself what is implicit in a thought or a conception, setting forth in a series the external and spiritual relations of the given content, and relating the particular features of it to one another. Unquestionably we think throughout in language, without, however, needing actual speech as spoken. By reason of this ability to dispense with speech-utterance in its sensuous aspect as contrasted with the spiritual content of ideas, etc., to elucidate which they[404] are employed, tone receives once more self-subsistency. In the art of painting no doubt colour and its arrangement, regarded simply as colour, is likewise by itself without significance, and in the same way, as contrasted with the spiritual embodied, thereby a self-substantive sensuous medium; but we get no painting from colour simply as such: we must first attach to it form and its expression. With these spiritually animated forms colouring is brought into an association by many degrees more constrained than that which pertains to uttered speech and its coalescing result of words with ideas.
If we will now look at the distinction between the poetical and musical use of tones we shall find that music does not depress the tone sound to the mere speech-utterance, but creates out of tone simply its own independent medium, so that, in so far as there is musical tone, it is treated as the object of the art[405]. And on account of this the realm of tone, inasmuch as it cannot serve merely as a symbol, is by virtue of this emancipated function of its life[406] able to attain to a mode of configuration, which makes the form that is its peculiar possession, that is to say, the modes of tone as artistically developed, its fundamental aim and object. In recent times especially, the art of music, by its wresting itself from all content that is independently lucid, has withdrawn into the depths of its own medium. But on this very account and to this extent it has lost its compelling power[407] over the soul, inasmuch as the enjoyment, which is thus offered, is only applicable to one aspect of art, in other words, is only an interest in the purely musical characteristics of the composition and its artistic dexterity, an aspect which wholly concerns the musical expert, and is less connected with the universal human interest in art.
(ββ) All that poetry loses, however, in external objectivity by being able to place on one side its sensuous medium, in so far as that can be wholly dispensed with by art, it secures for itself, in the ideal objectivity of its vision and ideas, which poetical speech presents to soul and mind. For it is the function of imagination to clothe these concepts, emotions, and thoughts in a world that is itself essentially complete[408] with its events, actions, moods, and exhibitions of passion, and by this means it creates works, into which the entire fabric of reality, both in its external aspect as phenomena and in the ideal significance of its content, is brought home to the emotions, vision, and imagination of spiritual life. It is this type of objectivity which the art of music, in so far as it asserts its independent claims in its own province, is compelled to renounce. In other words, the realm of tone possesses, no doubt, as I have already indicated, a relation to the soul, and an alliance which is consonant with its spiritual movement; but it fails to pass beyond a sympathetic relation which is always of an indefinite character, albeit in this aspect of it a musical composition, if originating in the soul-life itself, and permeated by genius and emotions of a rich quality, cannot fail to react on our nature with an equivalent power and variety. In the case of a content and the ideal and personal creation such as poetry implies our emotions pass more completely out of their elementary medium of undefined conscious life into the more concrete vision and more universal[409] imagination which is embodied in such content. This may also be the effect of a musical composition, so soon as the emotions which it excites in ourselves by virtue of its own nature and the artistic energy that animates it are involved more closely in ourselves with a distinct vision and ideas, and thereby present to consciousness the tangible definition of soul-impressions in a more stable outlook and more universally accepted ideas. This is, however, our imagination and vision, which no doubt has been suggested by the musical work, but which has not been itself directly disclosed by virtue of the artistic elaboration of musical tones. Poetry, on the contrary, expresses emotions, perceptions, and ideas as they are[410], and is further able to delineate a picture of external objects, although it cannot itself either attain to the plastic clarity of sculpture and painting or the spiritual intimacy of music, and is consequently obliged to call as auxiliary to its powers the direct vision we otherwise receive through the senses and the speechless apprehension of soul-life in music.
