The same tendency is observable in chamber and pianoforte music. Not only are modern composers fond of curious groupings of wind and string instruments, as in the trumpet septet of Saint-Saëns, the clarinet quintet and horn trio of Brahms, and other such works, but when they use only the four stringed instruments they combine contrasting rhythms and modes of phrasing, as well as pizzicato, the sordino, the high register of the 'cello, and other exotic devices, with an unfailing sense of color-values. Schubert is the first conspicuous example of this sort of quartet writing; Dvořák is his worthy follower. As for the piano, there is almost as much difference between the piano writing of Beethoven, so often thick, harsh, and lumpish, and the ramifying figuration of Schumann or the wide, clear arpeggiated accompaniments and flowering scale-figures of Chopin as there is between the coloring of Rembrandt and that of Monet.

All this gain in sensuous richness and technical elaboration is, however, to be considered largely as a concomitant rather than a direct result (though to some extent is was that) of the romantic movement. It was primarily merely a phase of that unparalleled material and mechanical progress so characteristic of the nineteenth century. The modern orchestra and the modern pianoforte are simply special examples of the ingenuity of that century in mechanical devices; the genius which turned the clavichord into the piano was the same as that which substituted the propeller for sails, and the electric telegraph for the lumbering mail-coach. But if this modern mechanical genius has indeed brought to the musician priceless gifts, it is still important to remember that perfected mechanisms do not account for romantic music, which might conceivably have existed without them. Instruments alone cannot make music, any more than a steam derrick can build a bridge. If we wish to seize the true spirit of the modern musical art, we must, after all, leave orchestra, and piano, and sensuous value behind, and ascertain to what use composers have turned all these resources, and to what manner of expression, embodied in what kind of forms, they have been spurred by the romantic spirit.

III

Difficult to make, and dangerous when made, as are sweeping generalizations about so many-sided a matter as the expressive character of whole schools or eras of art, there seem to be generic differences between classical and romantic expression which we can hardly avoid remarking, and of which it is worth while to attempt a tentative definition, especially if we premise that it is to be suggestive rather than absolute. The constant generality of classical expression, and the objectivity of attitude which it indicates in the worker, cannot but strike the modern student, especially if he contrasts them with the exactly opposite features of contemporary art. The classical masters aim, not at particularity and minuteness of expression, but at the congruous setting forth of certain broad types of feeling. They are jealous of proportion, vigilant to maintain the balance of the whole work, rigorous in the exclusion of any single feature that might through undue prominence distort or mar its outlines. Their attitude toward their work is detached, impersonal, disinterested—a purely craftsmanlike attitude, at the furthest pole from the passionate subjectivity of our modern "tone-poets." J. S. Bach, for example, the sovereign spirit of this school, is always concerned primarily with the plastic problem of weaving his wonderful tonal patterns; we feel that what these patterns turn out to express, even though it be of great, and indeed often of supreme, poignancy, is in his mind quite a secondary matter. The preludes and fugues of the "Well-tempered Clavichord" are monuments of abstract beauty, rather than messages, pleas, or illustrations. And even when their emotional burden is so weighty as in the B-flat minor prelude or the B-minor fugue of the first book, it still remains general and, as it were, communal. Bach is not relieving his private mind; he is acting as a public spokesman, as a trustee of the emotion of a race or nation. This gives his utterance a scope, a dignity, a nobility, that cannot be accounted for by his merely personal character.

Haydn and Mozart illustrate the same attitude in a different department of music. Their symphonies and quartets are almost as impersonal as his preludes and fugues. The substance of all Haydn's best work is the folk-music of the Croatians, a branch of the Slavic race; its gaiety, elasticity, and ingenuousness are Slavic rather than merely Haydnish. It is true that he idealizes the music of his people, as a gifted individual will always idealize any popular art he touches; but he remains true to his source, and accurately representative of it, just as the finest tree contains only those elements which it can draw from the soil in which it grows. Mozart, more personal than Haydn, shares with him the aloofness, the reticence, of classicism. What could be more Greek, more celestially remote, than the G-minor Symphony, or the quintet in the same key? What could be less a detailed biography of a hero, more an ideal sublimation of his essential character, than the "Jupiter Symphony"? And even in such a deeply emotional conception as the introduction to the C-major quartet, can we label any specific emotion? Can we point to the measures and say, "Here is grief; here is disappointment; here is unrequited love"?

In Beethoven we become conscious of a gradually changing ideal of expression. There are still themes, movements, entire works, in which the dominant impulse is the architectonic zeal of classicism; and there is the evidence of the sketchbooks that this passionate individualist could subject himself to endless discipline in the quest of pure plastic beauty. But there are other things, such as the third, fifth, and ninth symphonies, the "Egmont" and "Coriolanus" overtures, the slow movement of the G-major concerto (that profoundly pathetic dialogue between destiny and the human heart), and the later quartets, in which a novel particularity and subjectivity of utterance make themselves felt. In such works the self-forgetful artist, having his vicarious life only in the serene beauty of his creations, disappears, and Ludwig van Beethoven, bursting with a thousand emotions that must out, steps into his place and commands our attention, nobly egotistic, magnificently individual. And then there is the "Pastoral Symphony," in which he turns landscape painter, and with minutest details of bird-notes and shepherds' songs and peasants' dances delineates the external objects, as well as celebrates the inner spirit, of the countryside. These things mark the birth of romanticism.

For romanticism is, in essence, just this modern subjectivity and individualism, just this shifting of the emphasis from abstract beauty, with its undifferentiated expressiveness, to personal communication, minute interest in the uttermost detail, impassioned insistence on each emotion for itself rather than as a subordinate member in an articulate organism, and, in extreme cases, to concrete objects, persons, and scenes in the extra-musical world. Musicians since Beethoven have inclined to exploit more and more that aspect of their art which is analogous to language, even when this means neglect of the other aspect, the nearest analogue of which is to be found in sculpture, architecture, and decorative painting. The modern watchword has come to be initiative rather than obedience, originality rather than skill, individuality rather than truth to universal human nature. It is, after all, one impulse, the impulse toward specialization, that runs through all the various manifestations of the romantic spirit, and may be traced alike in the lyricism of Schubert, the fanciful whimsicality of Schumann, the picturesqueness of Mendelssohn, the introspection of Chopin, and the realism of Berlioz and Liszt.

In Schubert, the first of the out-and-out romanticists, and the eldest of them all in point of time (his birth date falls in the eighteenth century), we find a curious grafting of a new spirit on an old stem. Brought up on the quartets and symphonies of Haydn and Mozart, making his first studies in boyishly literal imitation of them, he acquired the letter of the classical idiom as none of the others save Mendelssohn ever did. His works in sonata form, written up to 1816, might well have emanated from Esterhaz or Salzburg; the C-major Symphony, so far as general plan is concerned, would have done no discredit to Beethoven. Yet the spirit of Schubert is always lyrical. It was fated from his birth that he should write songs, for his was a typically sentimental temperament; and when he planned a symphony, he instinctively conceived it as a series of songs for instruments, somewhat more developed than those intended for a voice, but hardly different in kind. As a naturalist can reconstruct in fancy an extinct animal from a fossil jaw-bone, a musical historian might piece out a fair conception of what romanticism is, in the dearth of other evidence, from a study of "Erlkönig," or "Ständchen," or "Am Meer"; and the ideas he might thus form would be extended rather than altered by acquaintance with the "Unfinished Symphony" or the D-minor Quartet. The lyrical Schubert contrasts always with the heroic and impersonal Bach or Beethoven, much as Tennyson contrasts with Shakespeare, or Theocritus with Sophocles.

Schumann adds to the lyrical ardor of Schubert insatiable youthful enthusiasm, whimsicality, a richly poetic fancy, and a touch of mysticism. His songs are even more personal than Schubert's, and his piano pieces, especially the early ones, bristle with eccentricities. The particularity, minute detail, and personal connotation of the "Abegg Variations," the "Davidsbündertänze," the "Papillons," the "Carnaval," the "Kreisleriana," are almost grotesque. He confides to us, through this music, his friendships, his flirtations, his courtship, his critical sympathies, his artistic creed, his literary devotions. Never was music so circumstantial, so autobiographic. In later years, when he had passed out of the enchanted circle of youthful egotism, and was striving for a more universal speech, his point of view became not essentially less personal but only less wayward. Till the last his art is vividly self-conscious—that is his charm and his limitation. No one has so touchingly voiced the aspirations of the imprisoned soul, no one has put meditation and introspection into tones, as he has done in the adagio of the C-major Symphony, the "Funeral March" of the Quintet, the F-sharp major Romance for piano.

If Schumann sounds, as no other can, the whole gamut of feeling of a sensitive modern soul, Mendelssohn, quite dissimilar in temperament,—correct, reserved, dispassionate,—is nevertheless also romantic by virtue of his picturesqueness, his keen sense for the pageantry of life, his delicate skill as an illustrator of nature and of imaginative literature. His "Songs without Words" reveal a strain of mild lyricism, but he is never intimate or reckless, he never wholly reveals himself. His discreet objectivity is far removed from the frankly subjective enthusiasms of Schubert and Schumann. He was, in fact, by tradition, training, and native taste, a classicist; the exhibition of deep feeling was distasteful to his fastidious reticence; and he is thus emotionally less characteristic of his period than any of his contemporaries. But for all that he shows unmistakably in the felicity of his tone-painting the modern interest in picturesque detail, in the concrete circumstance, the significant particular. Illustration rather than abstract beauty—that is one of the special interests of the new school. No one has cultivated it more happily than the composer of the "Midsummer Night's Dream" music, the "Hebrides Overture," and the "Scotch" and "Italian" Symphonies.
