Between 1769 and 1773 the young Wolfgang Amadeus Mozart and his father Leopold made three Italian journeys. The first, an extended tour of 15 months, was financed by performances for the nobility and by public concerts, and took in the most important Italian cities. The later journeys were to Milan, for Wolfgang to complete operas that had been commissioned there on the first visit. Leopold had been employed since 1747 as a musician in the Archbishop of Salzburg's court, becoming deputy Kapellmeister in 1763; but he had also devoted much time to Wolfgang's and sister Nannerl's musical education. He took them on a "grand tour" between 1764 and 1766, and spent some of 1767 and most of 1768 with them in the imperial capital, Vienna. The children's performances had captivated audiences, especially early in these journeys; and they made a considerable impression on European society. By 1769 Nannerl had reached adulthood, but Leopold was anxious to continue 13-year-old Wolfgang's education in Italy, a crucially important destination for any young composer of the 18th century.
