In his piano playing he represented quite another school from that of Liszt. He was gentle where Liszt was frenzied; he was graceful where Liszt was pompous. Or, rather, his playing was of no school, but was simply his own. His imitators exaggerated his characteristics, carrying his _rubato_ to a silly extreme. But no competent witness has testified that Chopin ever erred in taste. The criticism was constantly heard, during his lifetime, that he played too softly, that his tone was insufficient to fill a large hall. It was his style; he did not change because of his critics. He was not, perhaps, a virtuoso of the first rank, but all agree that the things which he did he did supremely well. The supreme grace of his compositions found its best exponent in him. Ornaments, such as the cadenzas of the favorite E flat Nocturne, he played with a liquid quality that no one could imitate. His rubato carried with it a magical sense of personal freedom, but was never too marked--was not a rubato at all, some say, since the left hand kept the rhythm quite even. As a workman Chopin was conscientious in the extreme. He never allowed a work to go to the engraver until he had put the last possible touch of perfection to it. His posthumous compositions he desired never to have published. His judgment of them was correct; they are in almost every case inferior to the work which he gave to the public. Just where his individuality came from, no one can say; it seems to have been born in him. From Field[81] he borrowed the Nocturne form, or rather name. From Hummel[82] and Cramer[83] he borrowed certain details of pianistic style. From the Italians he caught a certain luxurious grace that is not to be found in French or German music. But none of this explains the genius by which he turned his borrowings into great music.
