To return to the historical view, the course of the symphony during the century cannot be adequately scanned without a glance at the music-drama of Richard Wagner. Until the middle of the century, symphony and opera had moved entirely in separate channels. At most the overture was affected, in temper and detail, by the career of the nobler form.

The restless iconoclasm of a Liszt was now united, in a close personal and poetic league, with the new ideas of Wagner's later drama. Both men adopted the symbolic motif as their main melodic means; with both mere iteration took the place of development; a brilliant and lurid color-scheme (of orchestration) served to hide the weakness of intrinsic content; a vehement and hysteric manner cast into temporary shade the classic mood of tranquil depth in which alone man's greatest thought is born.

But a still larger view of the whole temper of art in Europe of the later century is needed. We wander here beyond the fine distinctions of musical forms. A new wave of feeling had come over the world that violently affected all processes of thought. And strangely, it was strongest in the land where the great heights of poetry and music had just been reached. Where the high aim of a Beethoven and a Goethe had been proclaimed, arose a Wagner to preach the gospel of brute fate and nature, where love was the involuntary sequence of mechanical device and ended in inevitable death, all overthrowing the heroic idea that teems throughout the classic scores, crowned in a greatest symphony in praise of "Joy."

Such was the intrinsic content of a "Tristan and Isolde" and the whole "Nibelungen-Ring," and it was uttered with a sensuous wealth of sound and a passionate strain of melody that (without special greatness of its own) dazzled and charmed the world in the dramatic setting of mediaeval legend. The new harmonic style of Wagner, there is good reason to suppose, was in reality first conceived by Liszt, whose larger works, written about the middle of the century, have but lately come to light.[[1]] In correspondence with this moral mutiny was the complete revolt from classic art-tradition: melody (at least in theory), the vital quality of musical form and the true process of a coherent thread, were cast to the winds with earlier poetic ideals.

If it were ever true that a single personality could change an opposite course of thought, it must be held that Richard Wagner, in his own striking and decadent career, comes nearest to such a type. But he was clearly prompted and reinforced in his philosophy by other men and tendencies of his time. The realism of a Schopenhauer, which Wagner frankly adopted without its full significance (where primal will finds a redemption in euthanasia), led by a natural course of thought to Nietzsche's dreams of an overman, who tramples on his kind.

In itself this philosophy had been more of a passing phase (even as Schopenhauer is lost in the chain of ethical sages) but for its strange coincidence with the Wagnerian music. The accident of this alliance gave it an overwhelming power in Germany, where it soon threatened to corrupt all the arts, banishing idealism from the land of its special haunts.[[2]] The ultimate weakness of the Wagnerian philosophy is that it finds in fatalism an excuse for the surrender of heroic virtue,—not in the spirit of a tragic truth, but in a glorification of the senses; just as in Wagner's final work, the ascetic, sinless type becomes a figure almost of ridicule, devoid of human reality. It is significant that with the revival of a sound art, fraught with resolute aspiration, is imminent a return to an idealistic system of philosophy.

In the musical art even of Germany the triumph was never complete. The famous feud of Brahms and Wagner partisans marked the alignment of the classical and radical traditions. Throughout the second half of the century the banner of a true musical process was upheld; the personal meeting of the youthful Brahms with the declining Schumann is wonderfully significant, viewed as a symbol of this passing of the classic mantle. And the symphonies of Gustav Mahler seem an assurance of present tendencies. The influence of Bach, revived early in the century, grew steadily as a latent leaven.

Nevertheless in the prevailing taste and temper of present German music, in the spirit of the most popular works, as those of Richard Strauss (who seems to have sold his poetic birthright), the aftermath of this wave is felt, and not least in the acclaim of the barren symphonies of a Bruckner. It is well known that Bruckner, who paid a personal homage to Wagner, became a political figure in the partisan dispute, when he was put forth as the antagonist of Brahms in the symphony. His present vogue is due to this association and to his frank adoption of Wagner idiom in his later works, as well as, more generally, to the lowered taste in Germany.

In all this division of musical dialect, in the shattering of the classic tower among the diverse tongues of many peoples, what is to be the harvest? The full symbol of a Babel does not hold for the tonal art. Music is, in its nature, a single language for the world, as its alphabet rests on ideal elements. It has no national limits, like prose or poetry; its home is the whole world; its idiom the blended song of all nations.

In such a view there is less hope in the older than in the newer world. No single, limited song of one nation can in the future achieve a second climax of the art. It is by the actual mingling of them all that the fairest flower and fruit must come. The very absence of one prevailing native song, held a reproach to America, is in reality her strength; for hers is the common heritage of all strains of song. And it may be her destiny to lead in the glorious merging of them all.
