| The accounts of this admirable composer’s early proficiency in music are almost incredible. Mozart began the piano at three years of age. At five years old he began to invent little pieces of such ingenuity that his father used to write them down. When scarcely able to walk, his first question to the friends who took him on their knee was, whether they loved him, and a negative always made him weep. At six years old this singular. child commenced with his father and sister (two years older than himself) one of those musical tours common in Cermany, and performed at Munich before the Elector, to the great admiration of the most musical court on the continent. When only seven years old Mozart taught himself the violin; and thus, by the united effort of genius and industry; mastered the most difficult of all instruments. From Munich, he went to Vienna, Paris, and London. His reception in the British metropolis was such as the curious give to novelty, the scientific to intelligence, and the great to what administers to stately pleasure. He was flattered, honored, and rewarded. His execution, which on the piano had astonished the English musicians, on the organ, brought in aid of his genius, and be overcame all rivalry. On his departure from England, Mozart gave a farewell concert, of which all the symphonies were composed by him. That was the career of a child nine years old ! |
