As a mere player, the popularity of Mr. Gottschalk with the uninitiated masses is due, in a great measure, to his tact in discerning the American craving for novelty and sensation, and to his native originality and brilliancy, which allow him to respond so fully to these exigencies of public taste, as to possess on all occasions the keynote to applause. The faculty of never degenerating into dulness, the rock on which most pianists are wrecked in early youth, is another just cause for insuring to our compatriot the preeminence which he enjoys. Viewed from a critical point, the mechanical endowments and acquirements of Gottschalk are such as to enable him to subject his playing to the test of keenest analysis without detriment to his reputation. For clearness and limpidity of touch and unerring precision, for impetuosity of style, combined with dreamy delicacy, he has few rivals. The evenness and brilliancy of his trill are unequalled, the mechanical process required to produce it being lost to sight in the wonderful birdlike nature of the effect. In the playing of classical music, Mr. Gottschalk has to contend against his own individuality. This individuality, naturally intense and of a kind calculated to meet with public favor, has been cultivated and indulged in to such an extent as to prove an occasional obstacle to the exclusive absorption and utter identification with the ideas of another composer that classical music demands. In the mere matter of execution there is no difficulty which the fingers of this skilful pianist cannot overcome, and his intellectual grasp of a subject enables him to discern and interpret the beauties of all musical themes; but where an earnest, passionate interest in the music of the old masters is not felt by the performer, it is rarely communicated to his hearers. The world of letters, however, has not seemingly regretted the inability of Byron to trammel his muse with the uncongenial fetters of Pope's metre, and has certainly never quarrelled with Tom Moore for not assuming the manners and diction of the revered Samuel Johnson, LL.D.
