He made a tour to the north of Italy, and heard the Italian musician Paganini, which fired him with so much ardor, that he immediately set himself to transcribe his Caprices for the piano, and to accomplish upon this instrument similar effects to those which Paganini produced upon the violin. At length, after much difficulty with his guardian and his mother, it was agreed that he might fit himself for a musician, so in 1830 he was back again in Leipsic studying diligently with Master Wieck. In his ardor for great results in a short time, he undertook some kind of mechanical discipline for the fourth finger of his right hand, the effect of which was that the tendons became overstrained, the finger crippled, and for a long time he was utterly unable to use it in piano playing. In composition he now entered upon regular instruction with Heinrich Dorn, at that time conductor of the opera in Leipsic. Dorn recognized the greatness of Schumann's genius, and devoted himself with much interest to his improvement. In 1832 a symphony of his was produced in Zwickau, but apparently with little success, for the work was never heard of afterward. At this same concert Wieck's daughter, Clara, who was then thirteen years of age, appeared as a pianist, and Zwickau, Schumann says, "was fired with enthusiasm for the first time in its life." Already he was very much interested in the promising girl, and expresses himself concerning her with much ardor. He seems to have been singularly slow in composition. At this time, 1833, he had written the first and third movements of the G minor sonata, had commenced the F minor sonata and completed the "Toccata," which had been begun four years before. He also arranged the second set of Paganini's caprices, Opus 10. He found a faithful friend in Frau Voigt, a pianist of sense and ability. Schumann usually passed his evenings in a restaurant in company with his friends, after the German fashion, but while the others talked he usually remained silent. Frau Voigt told W. Taubert that one lovely summer evening after making music with Schumann, they both felt inclined to go upon the water. They sat side by side in the boat for an hour in silence. At parting Schumann pressed her hand and said, "Good day, we have perfectly understood one another."
