In 1747 Leopold Mozart married Anna Maria Pertlin, a foster-child of the Convent of St. Gilgen. The fruits of this marriage were seven children, two of whom alone survived,—Maria Anna, (the fourth), called Nannerl, born in 1751; and the youngest, Wolfgang Amadeus Johannes Chrysostomus. The daughter at a very early age displayed a most remarkable talent for music, and when her father began to give her instructions in it, an inborn and passionate love of this art was soon evident in her little brother of three years old, who at once gave tokens of a degree of genius far surpassing all experience, and really bordering on the marvellous. In his fourth year he could play all sorts of little pieces on the piano. He only required half an hour to learn a minuet, and one hour for a longer movement; and in his fifth year he actually composed some pretty short pieces, several of which are still extant.

The wonderful acquirements of both these children, to which Wolfgang soon added skilful playing on the violin and organ, induced their father to travel with them. In January, 1702, when the boy was just six years old, they went first to Munich, and in the autumn to Vienna, the children everywhere on their journey exciting the greatest sensation, and being handsomely remunerated. Leopold Mozart, therefore, soon afterwards resolved to undertake a longer journey, accompanied by his whole family. This lasted more than three years, extending from the smaller towns in West Germany to Paris and London, while they visited, on their way back, Holland, France, and Switzerland. The careful musical instruction which the father perseveringly bestowed on his son, went hand in hand with the most admirable education, and the boy was soon as universally beloved for his amiable disposition and natural simplicity and candor, as admired for his rare gifts and acquirements.
