When Wolfgang had attained his fourth year, says M. Schlichtegroll, his father began, though hardly in earnest, to teach him a few minuets and other short pieces of music. It took the child half an hour to learn a minuet, and proportionately more time to master compositions of greater length. In less than two years he had made such progress, that he invented short pieces of music, which his father, to encourage such promising talent, committed to writing. It is to be regretted that not one of these curious manuscripts, if preserved, has ever been produced. Before he began to manifest a predilection for music, his amusements were like those of other children; and so ardent was he in the pursuit of them, that he would willingly have sacrificed his meals rather than be interrupted in his enjoyment. His great sensibility was observable as soon as he could make his feelings understood. Frequently he said to those about him, “Do you love me well?” and when in sport he was answered in the negative, tears immediately began to flow. He pursued everything with extraordinary ardour. While learning the elements of arithmetic, the tables, chairs, even the walls, bore in chalk the marks of his calculations. And here it will not be irrelevant to state,—what we believe has never yet appeared in print,—that his talent for the science of numbers was only inferior to that for music: had he not been distinguished by genius of a higher order, it is probable that his calculating powers would have been sufficiently remarkable to bring him into general notice.
