On April 10, 1830, Chopin writes that his Concerto is not yet finished; and on May 15, 1830:—

The Rondo for my Concerto is not yet finished, because the
right inspired mood has always beep wanting. If I have only
the Allegro and the Adagio completely finished I shall be
without anxiety about the Finale. The Adagio is in E major,
and of a romantic, calm, and partly melancholy character. It
is intended to convey the impression which one receives when
the eye rests on a beloved landscape that calls up in one's
soul beautiful memories—for instance, on a fine, moonlit
spring night. I have written violins with mutes as an
accompaniment to it. I wonder if that will have a good
effect? Well, time will show.
August 21, 1830.—Next month I leave here; first, however, I
must rehearse my Concerto, for the Rondo is now finished.

For an account of the rehearsals of the Concerto and its first public performance at Chopin's third Warsaw concert on October u, 1830, the reader is referred to the tenth chapter (p. 150). [FOOTNOTE: In the following remarks on the concertos I shall draw freely from the critical commentary on the Pianoforte Works of Chopin, which I contributed some years ago (1879) to the Monthly Musical Record.]

Chopin, says Liszt, wrote beautiful concertos and fine sonatas, but it is not difficult to perceive in these productions "plus de volonte que d'inspiration." As for his inspiration it was naturally "imperieuse, fantasque, irreflechie; ses allures ne pouvaient etre que libres." Indeed, Liszt believes that Chopin—

did violence to his genius every time he sought to fetter it
by rules, classifications, and an arrangement that was not
his own, and could not accord with the exigencies of his
spirit, which was one of those whose grace displays itself
when they seem to drift along [alter a la derive]....The
classical attempts of Chopin nevertheless shine by a rare
refinement of style. They contain passages of great interest,
parts of surprising grandeur.

With Chopin writing a concerto or a sonata was an effort, and the effort was always inadequate for the attainment of the object—a perfect work of its kind. He lacked the peculiar qualities, natural and acquired, requisite for a successful cultivation of the larger forms. He could not grasp and hold the threads of thought which he found flitting in his mind, and weave them into a strong, complex web; he snatched them up one by one, tied them together, and either knit them into light fabrics or merely wound them into skeins. In short, Chopin was not a thinker, not a logician—his propositions are generally good, but his arguments are poor and the conclusions often wanting. Liszt speaks sometimes of Chopin's science. In doing this, however, he misapplies the word. There was nothing scientific in Chopin's mode of production, and there is nothing scientific in his works. Substitute "ingenious" (in the sense of quick-witted and possessed of genius, in the sense of the German geistreich) for "scientific," and you come near to what Liszt really meant. If the word is applicable at all to art, it can be applicable only to works which manifest a sustained and dominating intellectual power, such, for instance, as a fugue of Bach's, a symphony of Beethoven's, that is, to works radically different from those of Chopin. Strictly speaking, the word, however, is not applicable to art, for art and science are not coextensive; nay, to some extent, are even inimical to each other. Indeed, to call a work of art purely and simply "scientific," is tantamount to saying that it is dry and uninspired by the muse. In dwelling so long on this point my object was not so much to elucidate Liszt's meaning as Chopin's character as a composer.

Notwithstanding their many shortcomings, the concertos may be said to be the most satisfactory of Chopin's works in the larger forms, or at least those that afford the greatest amount of enjoyment. In some respects the concerto-form was more favourable than the sonata-form for the exercise of Chopin's peculiar talent, in other respects it was less so. The concerto-form admits of a far greater and freer display of the virtuosic capabilities of the pianoforte than the sonata-form, and does not necessitate the same strictness of logical structure, the same thorough working-out of the subject-matter. But, on the other hand, it demands aptitude in writing for the orchestra and appropriately solid material. Now, Chopin lacked such aptitude entirely, and the nature of his material accorded little with the size of the structure and the orchestral frame. And, then, are not these confessions of intimate experiences, these moonlight sentimentalities, these listless dreams, &c., out of place in the gaslight glare of concert-rooms, crowded with audiences brought together to a great extent rather by ennui, vanity, and idle curiosity than by love of art?

The concerto is the least perfect species of the sonata genus; practical, not ideal, reasons have determined its form, which owes its distinctive features to the calculations of the virtuoso, not to the inspiration of the creative artist. Romanticism does not take kindly to it. Since Beethoven the form has been often modified, more especially the long introductory tutti omitted or cut short. Chopin, however, adhered to the orthodox form, taking unmistakably Hummel for his model. Indeed, Hummel's concertos were Chopin's model not only as regards structure, but also to a certain extent as regards the character of the several movements. In the tutti's of the first movement, and in the general complexion of the second (the slow) and the third (Rondo) movement, this discipleship is most apparent. But while noting the resemblance, let us not overlook the difference. If the bones are Hummel's (which no doubt is an exaggeration of the fact), the flesh, blood, and soul are Chopin's. In his case adherence to the orthodox concerto-form was so much the more regrettable as writing for the orchestra was one of his weakest points. Indeed, Chopin's originality is gone as soon as he writes for another instrument than the pianoforte. The commencement of the first solo is like the opening of a beautiful vista after a long walk through dreary scenery, and every new entry of the orchestra precipitates you from the delectable regions of imagination to the joyless deserts of the actual. Chopin's inaptitude in writing for the orchestra is, however, most conspicuous where he employs it conjointly with the pianoforte. Carl Klindworth and Carl Tausig have rescored the concertos: the former the one in F minor, the latter the one in E minor. Klindworth wrote his arrangement of the F minor Concerto in 1867-1868 in London, and published it ten years later at Moscow (P. Jurgenson).[FOOTNOTE: The title runs: "Second Concerto de Chopin, Op. 21, avec un nouvel accompagnement d'orchestre d'apres la partition originale par Karl Klindworth. Dedie a Franz Lizt." It is now the property of the Berlin publishers Bote and Bock.] A short quotation from the preface will charactise his work:—

The principal pianoforte part has, notwithstanding the entire
remodelling of the score, been retained almost unchanged.
Only in some passages, which the orchestra, in consequence of
a richer instrumentation, accompanies with greater fulness,
the pianoforte part had, on that account, to be made more
effective by an increase of brilliance. By these divergences
from the original, from the so perfect and beautifully
effectuating [effectuirenden] pianoforte style of Chopin,
either the unnecessary doubling of the melody already
pregnantly represented by the orchestra was avoided, or—in
keeping with the now fuller harmonic support of the
accompaniment—some figurations of the solo instrument
received a more brilliant form.

Of Tausig's labour [FOOTNOTE: "Grosses Concert in E moll. Op. 11." Bearberet von Carl Tausig. Score, pianoforte, and orchestral parts. Berlin: Ries and Erler.] I shall only say that his cutting-down and patching-up of the introductory tutti, to mention only one thing, are not well enough done to excuse the liberty taken with a great composer's work. Moreover, your emendations cannot reach the vital fault, which lies in the conceptions. A musician may have mastered the mechanical trick of instrumentation, and yet his works may not be at heart orchestral. Instrumentation ought to be more than something that at will can be added or withheld; it ought to be the appropriate expression of something that appertains to the thought. The fact is, Chopin could not think for the orchestra, his thoughts took always the form of the pianoforte language; his thinking became paralysed when he made use of another medium of expression. Still, there have been critics who thought differently. The Polish composer Sowinski declared without circumlocution that Chopin "wrote admirably for the orchestra." Other countrymen of his dwelt at greater length, and with no less enthusiasm, on what is generally considered a weak point in the master's equipment. A Paris correspondent of the Neue Zeitschrift fur Musik (1834) remarked a propos of the F minor Concerto that there was much delicacy in the instrumentation. But what do the opinions of those critics, if they deserve the name, amount to when weighed against that of the rest of the world, nay, even against that of Berlioz alone, who held that "in the compositions of Chopin all the interest is concentrated in the piano part, the orchestra of his concertos is nothing but a cold and almost useless accompaniment"?
