text: Italy In 1737 Gluck arrived in Milan, and was introduced to Giovanni Battista Sammartini, who, according to Giuseppe Carpani, taught Gluck "practical knowledge of all the instruments". Apparently, this relationship lasted for several years. Sammartini was not, primarily, a composer of opera, his main output being of sacred music and symphonies, but Milan boasted a vibrant opera scene, and Gluck soon formed an association with one of the city's up-and-coming opera houses, the Teatro Regio Ducale. There his first opera Artaserse was performed on 26 December 1741, dedicated to Otto Ferdinand von Abensberg und Traun. Set to a libretto by Metastasio, the opera opened the Milanese Carnival of 1742. According to one anecdote, the public would not accept Gluck's style until he inserted an aria in the lighter Milanese manner for contrast.
  Nevertheless, Gluck composed an opera for each of the next four Carnivals at Milan, with renowned castrato Giovanni Carestini appearing in many of the performances, so the reaction to Artaserse was likely to have been reasonably favorable. He also wrote operas for other cities of Northern Italy in between Carnival seasons, including Turin and Venice, where his Ipermestra was given during November 1744 at the Teatro San Giovanni Crisostomo. Nearly all of his operas in this period were set to Metastasio's texts, despite the poet's dislike for his style of composition.
