Music has been betrayed into a position where she has lost sight of her own limitations; although in herself she is simply an "organ of expression," she has fallen into "the error of desiring to define with perfect clearness the thing to be expressed." The musical basis of the opera was the aria, that is, the folk-song deprived of its own original words, and adapted at once to the vanity of the singer and the luxurious tastes of the world of rank. Aria and dance-tune, with an admixture of recitative, made up an opera, into the musical domain of which the poet was only allowed to enter in order to supply a little narrative cohesion. The significance of the so-called reformation of Gluck has been greatly exaggerated. All he did was to curtail the arrogant pretensions of the singer, while leaving the texture and plan of opera untouched. His was a revolt of the composer fighting merely for his own hand, not for the ends of drama: and every means by which he increased the power of music in opera was necessarily a further shackle on the limbs of the poet. Méhul, Cherubini and Spontini in their turn broadened the old musical forms of opera, and made the musical expression more consonant with that of the words, but did nothing for opera except from the standpoint of music. The poet may now have had to provide a slightly better and firmer groundwork for the musician, but it was to the musician, and to him alone, that he still owed his existence in opera. People failed to see that the source of regenerative power could be nowhere but in the drama: and the trouble was that music tried by itself to perform the functions of drama, to be a "content" instead of mere "expression."
Mozart, again, was so entirely a musician that his work throws the clearest light on the relations of musician and poet; and we find him unable to write at his best where the poem was flat and meaningless. He could not write music for Tito like that of Don Giovanni, or for Cosi fan tutte like that of Figaro. He, the most absolute of all musicians, would long ago have solved the operatic problem had he met the proper poet. This poet he was never fortunate enough to meet: all his "poets" did was to give him a medley of arias, duets, and ensembles to set to music. But the flood of beauty and expression which Mozart poured into opera was too great for that narrow bed; the stream overflowed into wider and freer channels, until it became a mighty sea in the symphonies of Beethoven.
The aria was a degeneration of the folk-song, in which poetry and music had been spontaneously one. The operatic aria was the music of the folk-song, arbitrarily wrested from the words, and made to serve the indolent pleasure of the man of luxury. In course of time people forgot that a word-stave should by rights go with the melody. It was Rossini who took this artificial flower, drenched it with manufactured perfume, and gave it the semblance of life. Rossini saw that the life-blood of ordinary opera was melody—"naked, ear-tickling, absolute-melodic melody." Spontini erred in imagining the "dramatic tendency" to be the essence of opera: the real essence, as Rossini showed, and as the future history of opera proves, was simply absolute melody.
Earnest composers, however, while by no means denying the claims of melody, held that Rossini's melody was cheap and superficial, and endeavoured to derive theirs more directly from the fountains of expression of the Folk. This was the course taken by Weber, who gave opera-aria the deep and genuine feeling of the folk-song; though the flower, thus torn from its native meadow, could not thrive in the salons of modern luxury and artificiality. And Weber, no less than Rossini, made his melody the main factor of opera, though of course it was far worthier and more honest than the melody of the Italian composer. Weber directed and constrained the poet of Der Freischütz as emphatically as Rossini did the poet of Tancredi. And Weber's failure proves afresh the assertion that instead of the drama being taken up into the being of music, music must be taken up into the drama.
Weber's success in harking back to the Folk was envied by the composers of other nationalities, and a number of operas were produced which tried to proceed on similar lines—such as Masaniello and William Tell. The Folk, in fact, was exploited, but its real inspiration could not, from the very nature of the case, be embodied in opera. In the epic and the drama the Folk celebrated the deeds of the Hero, and in true drama the action and the character are recognised as necessary; but under the influence of the modern State, dramatic characters lose their personality and become mere masks. This was particularly the case in opera, where the folk-song has degenerated into the aria, and the Folk itself has become the Mass, the Chorus. "Historic" opera became the fashion, and even Religion was dragged upon the stage, as in the operas of Meyerbeer. But the outlandishness thus imported into opera led in its turn to worse degeneration: and the "historic" mania became "hysteric" mania—in other words, Neo-romanticism.
Up to this time, every influence that had shaped the course of opera had come from the domain of absolute music alone. After Rossini, operatic melody was varied by the introduction of instrumental melody. People had not perceived that instrumental music was also unfruitful, by reason of its not expressing the purely-human in the form of definite, individual feelings.
"That the expression of an absolutely definite and clearly-understandable individual Content was in truth impossible in this language that was capable only of generalised emotional expression, could not be demonstrated until the coming of that instrumental composer in whom the longing to express such a Content became the burning, consuming motive-force of all artistic conception."
It was the function of Beethoven to show what music can do if it confines itself to its true sphere, that of expression. In his later works, Beethoven, having his mind filled with a definite content, burst the bounds of many of the old absolute forms, and stammered through tentative new ones. Future symphonists followed him from this point, without seeing what it was in Beethoven that made him act in this way; they consequently misapplied his forms, copying the externals only. Hence the vogue of programme music, of which the great representative is Berlioz. Then there came an influx of the wealth of instrumental music (developed independently of vocal music) into operatic melody. This is modern characteristic, of which Meyerbeer, the cosmopolitan Jew, is the great exploiter, and which differs from that of Gluck and Mozart in that the poet is infinitely more degraded, and absolute melody more exalted. This held good even in Paris, where the poet had hitherto always had some rights; but now Meyerbeer forced Scribe, his librettist, to run wherever he chose to drive him. The secret of his music is "Effect without Cause." Yet even Meyerbeer wrote fine music where he allowed the poet to guide him—as in parts of the great love-scene in the fourth act of Les Huguenots.
To sum up, then, Music has tried to be the drama, and the attempt has ended in impotence. The only salvation for it lies in sensible co-operation with the poet. This may be seen by a glance at the nature of our present music. The most perfect expression of the inner being of music is melody; it is to harmony and rhythm what the external side of the organism is to the internal. Now the Folk's melodies were a revelation of the nature of things. Christianity, however, with its anxiety to lay bare the soul, found itself face to face not with life but death; and the Folk-song, the indivorcible union of poetry and music, almost died out. In the ages of human mechanism the longing of things was to produce the real man, which man "was really none other than Melody, i.e. the moment of most definite, most convincing manifestation of Music's actual, living organism." The struggle of Beethoven's great works is the struggle of mechanism to become a man, an organism, uttering itself in melody. Thus while other composers merely took melody, ready-made, from the mouth of the Folk, and applied it to their own purposes, Beethoven's melody was the spontaneous effort of Music's inner organism to find expression. But it is only in the verbal outburst of the Ninth Symphony that Beethoven brings melody to true life; music was sterile until fertilised by the poet. The error had always been that operatic melody, coming as it did from the Folk-song, ran on certain rhythmical and structural lines, beyond which the musician could not stray; so that melody had no chance to be born spontaneously out of poetry, for the poet had simply to adapt his words to the one invariable musical scaffolding. "Every musical organism is by its nature a womanly; it is merely a bearer, not a begetter; the begetting force lies outside it, and without fecundation by this force it cannot bear." In the Choral Symphony Beethoven had to call in the poet to fertilise absolute music; and the folly of the latter is seen in its attempts not only to bear but also to beget. "Music is a woman," whose nature is to surrender in love. Who now is to be the Man to whom this surrender is to be made? Let us look at the Poet.
