What was the cause of Mozart’s disaffection with Salzburg and his embrace of Vienna's world of musical opportunity? Settled in the Imperial capital, and after the cooling of relations with his father Leopold, and marriage to Constanze, Mozart composed the opera that enjoyed the greatest success in his lifetime, The Abduction from the Seraglio, performed all over Germany after its premiere in Vienna in 1782. The series of great piano concertos, in which Mozart as soloist dazzled the Viennese public with his keyboard virtuosity, brought fame and a degree of fortune, and this triumphant phase of Mozart’s career culminates in the rapprochement with his father, who visited Vienna in the early months of 1785 and was moved to tears by the richness and beauty of his son’s music. Leopold’s letters home to Mozart’s sister Nannerl give a fascinating glimpse of Mozart life at the pinnacle of his success.
