  Mozart's new career in Vienna began well. He often performed as a pianist, notably in a competition before the Emperor with Muzio Clementi on 24 December 1781, and he soon "had established himself as the finest keyboard player in Vienna". He also prospered as a composer, and in 1782 completed the opera Die Entführung aus dem Serail ("The Abduction from the Seraglio"), which premiered on 16 July 1782 and achieved considerable success. The work was soon being performed "throughout German-speaking Europe", and thoroughly established Mozart's reputation as a composer.
  
  Near the height of his quarrels with Colloredo, Mozart moved in with the Weber family, who had moved to Vienna from Mannheim. The family's father, Fridolin, had died, and the Webers were now taking in lodgers to make ends meet.
