It is quite possible that, in any case, Chopin would have found himself incapable of dealing with large masses. The want of virility, which has already been noted in his character, appears beyond question in his music; leaving untouched all the grace and tenderness, all the rare and precious qualities of workmanship, but relaxing into an almost inevitable weakness at any crisis which demands sustained force or tenacity. When he is at his strongest, we miss that sense of reserve power, that quiet irresistible force, 'too full for sound or foam,' which characterises the dignity of the noblest art. He can be passionate, vehement, impetuous, but he expends himself in the effort. He can express agitation, challenge, defiance, but he lacks the royal magnanimity that will never stoop to defy. Even his melody is never sublime, never at the highest level. Its more serious mood stands to the great tunes of Beethoven as Leopardi stands to Dante, rising for a moment on a few perfect lines to follow the master's flight, and then sinking back to earth under some load of weariness or impatience.
Take, for instance, the B flat minor Sonata, in which Chopin most nearly approximates to the 'grand manner' of composition. The first movement, regarded by itself, is a masterpiece; its exposition clear and concise, its subjects well contrasted, one for thematic treatment and one for melody, its free fantasia an admirable example of an established type, and its recapitulation, though a little too short for perfect balance, a firm and lucid statement which sums up its results without a bar of vagueness or uncertainty. Not less complete is the Scherzo, which develops the simple forms of Mozart and Beethoven without obscuring their outline, and, despite all its rush and vigour, never allows its themes to get out of hand or to pass beyond the legitimate bounds of control. But from this point the value of the Sonata steadily declines. Schumann undoubtedly hits the blot when he declares that the great Funeral March ought never to have formed part of the work at all. As a separate piece it is of incomparable beauty; as the adagio of this particular Sonata it is wholly out of place. Its key is ill selected in relation to the rest of the composition; its contrasts of theme bear too much resemblance to those of the first movement; worst of all, its form is precisely the same as that of the Scherzo; and these objections, not one of which affects the movement in itself, are no less than fatal to it in its present context. The Finale, again, has neither the breadth nor the dignity requisite for its position. Its structure, though perfectly clear, is too simple and primitive to justify it as the fitting conclusion of an important work; and its persistent rhythmic figure gives it somewhat the air of an impromptu. If we had found it in the Volume of _Preludes_, we should have felt for it nothing but admiration; here, its inadequacy is so obvious that the greater part of critical attention has been distracted from its undeniable merits. In short, the first half of the Sonata gives promise of a Classic such as, with one exception, the world had not seen since the death of Beethoven; the second half, though almost every bar contains something that is beautiful, is a disappointment and a failure. Icarus has flown too near the sun, and the borrowed wings have no longer the strength to support him.
