Wolfgang Amadeus Mozart composed Symphony No. 27 G Major K 199 (161b / 162a) in April 1773, at the age of seventeen. At this time he had already travelled to Italy with his father Leopold, where he created, among other works, the operas Mitridate, re di Ponto, Ascanio in Alba, and Lucio Silla, and formed a close friendship with Josef Mysliveček, who was already an established and famous composer of opera seria and instrumental music, and who significantly influenced young Mozart at this stage of his career. However, despite the hopes of the Mozarts, Wolfgang failed to obtain a steady supply of contracts or a permanent engagement at an aristocratic court in Italy, and they returned to Austria, where Wolfgang gained employment at the court of Prince Archbishop Hieronymus of Colloredo, the last ruler of the Prince-Archbishopric of Salzburg. During this service, Mozart composed a large number of diverse works, including symphonies, sonatas, masses, string quartets, and violin concertos. This period also saw the creation of Symphony No. 27 G Major. It is one of the so-called “Salzburg symphonies” (together with symphonies no. 22, 23, 24, and 26). According to the hypothesis of Alfred Einstein, a prominent musicologist and expert on Mozart’s life and work, these symphonies were commissioned by an unknown Italian patron. The cast of the symphony requires two flutes, two French horns, and strings instruments, and a bassoon and a harpsichord were usually added. This delicate and light composition captivates listeners by its liveliness, sonority, and bright colours of the flutes and French horns.
