A spirit of departure the often-used catchword stands here not only in a figurative sense, but also for three different life situations of the young Wolfgang Amadeus Mozart, in which he left his not necessarily beloved hometown of Salzburg and set out for new shores elsewhere. In 1772, when he was only 16 years old, he traveled to Milan to conduct the rehearsals for the premiere of his new opera Lucio Silla achieved a new quality of character drawing and set the trend for Mozart's further operatic work. A few years later he revolutionized the genre of the piano concerto with the Jenamy concerto, the last one composed in Salzburg. Shortly thereafter, Mozart set out on another great journey. The innovations in the interplay between soloist and orchestra laid the foundation for his later successes with the Viennese piano concertos. Finally, the Symphony K. 338 was composed shortly before Mozart left Salzburg forever; musically, it too lays the foundations for the successful Viennese years that followed.
