Ole Bull's first visit to America was in 1843, and the impression produced by his playing was, for manifest causes, even greater than that created in Europe. He was the first really great violinist who had ever come to this country for concert purposes, and there was none other to measure him by. There were no great traditions of players who had preceded him; there were no rivals like Spohr, Paganini, and De Beriot to provoke comparisons. In later years artists discovered that this country was a veritable El Dorado, and regarded an American tour as indispensable to the fulfillment of a well-rounded career. But, when Ole Bull began to play in America, his performances were revelations, to the masses of those that heard him, of the possibilities of the violin. The greatest enthusiasm was manifested everywhere, and, during the three years of this early visit, he gave repeated performances in every city of any note in America. The writer of this little work met Ole Bull a few years ago in Chicago, and heard the artist laughingly say that, when he first entered what was destined to be such a great city, it was little more than a vast mudhole, a good-sized village scattered over a wide space of ground, and with no building of pretension except Fort Dearborn, a stockade fortification. Our artist returned to Europe in 1846, and for five years led a wandering life of concert-giving in England, France, Holland, Germany, Italy, and Spain, adding to his laurels by the recognition everywhere conceded of the increased soundness and musicianly excellence of his playing. It was indeed at this period that Ole Bull attained his best as a virtuoso. He had been previously seduced by the example of Paganini, and in the attempt to master the more strange and remote difficulties of the instrument had often laid himself open to serious criticism. But Ole Bull gradually formed a style of his own which was the outcome of his passion for descriptive and poetic playing, and the correlative of the mode of composition which he adopted. In still later years Ole Bull seems to have returned again to what might be termed claptrap and trickery in his art, and to have desired rather to excite wonder and curiosity than to charm the sensibilities or to satisfy the requirements of sound musical taste.
