Of the numerous criticisms of well-known composers contained in this correspondence, a few more may be cited. They are mostly favorable in tone, but concerning the "Prophète" he writes: "The music appears to me very poor; I cannot find words to express my aversion to it." "Lortzing's operas meet with success—to me almost incomprehensible." To Carl Reinecke he writes that he is "no friend of song-transcriptions (for piano), and of Liszt's some are a real abomination to me." He commends Reinecke's efforts in this direction because they are free from pepper and sauce à la Liszt. Nevertheless, those of Liszt's song-transcriptions in which he did not indulge in too much bravura ornamentation are models of musical translation, and the collection of forty-two songs published by Breitkopf & Härtel should be in every pianist's library. "Of Chopin," he writes in 1836, "I have a new ballad [G minor]. It seems to me to be his most enchanting (though not most genial) work; I told him, too, that I liked it best of all his compositions. After a long pause and reflection he said: 'I am glad you think so, it is also my favorite.' He also played for me a number of new études, nocturnes, mazurkas—everything in an incomparable style. It is touching to see him at the piano. You would be very fond of him. Yet Clara is more of a virtuoso, and gives almost more significance to his compositions than he does himself."
Brendel having sent him some of Palestrina's music, he writes that "it really sounds sometimes like music of the spheres—and what art at the same time! I am convinced he is the greatest musical genius Italy has produced." Nineteen years previous to this he had written from Brescia: "Were not the Italian language itself a kind of eternal music (the Count aptly called it a long-drawn-out A-minor chord), I should not hear anything rational. Of the ardor with which they play, you can form no more conception than of their slovenliness and lack of elegance and precision." Handel appears to be mentioned only once in all of Schumann's correspondence ("I consider 'Israel in Egypt' the ideal of a choral work"), but Bach is always on his tongue. The following is one of the profoundest criticisms ever written: "Mozart and Haydn knew of Bach only a few pages and passages, and the effect which Bach, if they had known him in all his greatness, would have had on them, is incalculable. The harmonic depth, the poetic and humorous qualities of modern music have their source chiefly in Bach: Mendelssohn, Bennett, Chopin, Hiller, all the so-called Romanticists (I mean those of the German school) approximate in their music much closer to Bach than to Mozart."
To Wagner there are several references, betraying a most remarkable struggle between critical honesty and professional jealousy. Thus, in 1845, Schumann writes to Mendelssohn of "Tannhäuser:"
"Wagner has just finished a new opera—no doubt a clever fellow, full of eccentric notions, and bold beyond measure. The aristocracy is still in raptures over him on account of his 'Rienzi,' but in reality he cannot conceive or write four consecutive bars of good or even correct music. What all these composers lack is the art of writing pure harmonies and four-part choruses. The music is not a straw better than that of 'Rienzi,' rather weaker, more artificial! But if I should write this I should be accused of envy, hence I say it only to you, as I am aware that you have known all this a long time."
But in another letter to Mendelssohn, written three weeks later, he recants: "I must take back much of what I wrote regarding 'Tannhäuser,' after reading the score; on the stage the effect is quite different. I was deeply moved by many parts." And to Heinrich Dorn he writes, a few weeks after this: "I wish you could see Wagner's 'Tannhäuser.' It contains profound and original ideas, and is a hundred times better than his previous operas, though some of the music is trivial. In a word, he may become of great importance to the stage, and, so far as I know him, he has the requisite courage. The technical part, the instrumentation, I find excellent, incomparably more masterly than formerly."
Nevertheless, seven years later still, he once more returns to the attack, and declares that Wagner's music, "apart from the performance, is simply amateurish, void of contents, and disagreeable; and it is a sad proof of corrupt taste that, in the face of the many dramatic master-works which Germany has produced, some persons have the presumption to belittle these in favor of Wagner's. Yet enough of this. The future will pronounce judgment in this matter, too." Poor Schumann! His own opera, "Genoveva," was a failure, while "Tannhäuser" and "Lohengrin" were everywhere received with enthusiasm. This was a quarter of a century ago; and the future has judged, "Tannhäuser" and "Lohengrin" being now the most popular of all works in the operatic repertory.
What caused the failure of Schumann's only opera was not a lack of dramatic genius, but of theatrical instinct. He believed that in "Genoveva" "every bar is thoroughly dramatic;" and so it is, as might have been expected of the composer of such an intensely emotional and passionate song as "Ich grolle nicht" and many others. But Schubert, too, could write such thrilling five-minute dramas as the "Erlking" and the "Doppelgänger," without being able to compose a successful opera. Like Schumann, he could not paint al fresco, could not command that bolder and broader sweep which is required of an operatic composer. It is characteristic of Schumann that he did not write an opera till late in life, whereas born operatic composers have commonly begun their career with their specialty. Indeed, it was only ten years before he composed his opera that Schumann wrote to a friend: "You ought to write more for the voice. Or are you, perhaps, like myself, who have all my life placed vocal music below instrumental, and never considered it a great art? But don't speak to anyone about this." Oddly enough, less than a year after this he writes to another friend: "At present I write only vocal pieces.... I can hardly tell you what a delight it is to write for the voice as compared with instruments, and how it throbs and rages within me when I am at work. Entirely new things have been revealed to me, and I am thinking of writing an opera, which, however, will not be possible until I have entirely freed myself from editorial work."
Like other vocal composers, Schumann suffered much from the lack of suitable texts. In one letter he suggests that Lenau might perhaps be induced to write a few poems for composers, to be printed in "The Zeitschrift:" "the composers are thirsting for texts." In several other letters we become familiar with some of his plans which were never executed, owing, apparently, to the shortcomings of the librettists. One of these was R. Pohl, who in all earnestness sent Schumann a serious text in which the moon was introduced as one of the vocalists! Schumann mildly remonstrated that "to conceive of the moon as a person, especially as singing, would be too risky." So the project of "Ritter Mond" was abandoned, and it is to be regretted that Schumann did not reject his "Genoveva" libretto, which was largely responsible for the failure of the opera.
One project of Schumann's is mentioned which it is to be very much regretted he never carried out. "I am at present [1840] preparing an essay on Shakspere's relations to music, his utterances and views, the manner in which he introduces music in his dramas, etc., etc.—an exceedingly fertile and attractive theme, the execution of which would, it is true, require some time, as I should have to read the whole of Shakspere's works for this purpose." His object was to send this to Jena as a dissertation for a Doctor's degree, with which he hoped to soften the heart of the obdurate Wieck, who opposed his marriage with Clara, and at the same time to make an impression on the public. Schumann had had painful experience of the fact that for genius itself there is little recognition in Germany unless it has a handle to its name—a "von" or a "Herr Doctor." Clara, however, loved him for his genius, and for the impassioned pieces and songs he wrote to express his admiration of her and of woman in general; and, like other German men of genius, he had his reward—after death. "No tone poet," says Naumann, "has been more enthusiastic in the praise of woman than Robert Schumann; he was a second Frauenlob. This was acknowledged by the maidens of Bonn, who, at his interment, filled the cemetery, and crowned his tomb with innumerable garlands."
