Wolfgang Amadeus Mozart

Vienna
1781: Departure
Mozart family, c. 1780 (della Croce); the portrait on the wall is of Mozart's mother.
In January 1781, Mozart's opera Idomeneo premiered with "considerable success" in Munich.^[45] The following March, Mozart was summoned to Vienna, where his employer, Archbishop Colloredo, was attending the celebrations for the accession of Joseph II to the Austrian throne. For Colloredo, this was simply a matter of wanting his musical servant to be at hand (Mozart indeed was required to dine in Colloredo's establishment with the valets and cooks).^[g] He planned a bigger career as he continued in the archbishop's service;^[47] for example, he wrote to his father:
My main goal right now is to meet the emperor in some agreeable fashion, I am absolutely determined he should get to know me. I would be so happy if I could whip through my opera for him and then play a fugue or two, for that's what he likes.^[48]
Mozart did indeed soon meet the Emperor, who eventually was to support his career substantially with commissions and a part-time position.
In the same letter to his father just quoted, Mozart outlined his plans to participate as a soloist in the concerts of the Tonkünstler-Societät, a prominent benefit concert series;^[48] this plan as well came to pass after the local nobility prevailed on Colloredo to drop his opposition.^[49]
Colloredo's wish to prevent Mozart from performing outside his establishment was in other cases carried through, raising the composer's anger; one example was a chance to perform before the Emperor at Countess Thun's for a fee equal to half of his yearly Salzburg salary.
The quarrel with the archbishop came to a head in May: Mozart attempted to resign and was refused. The following month, permission was granted, but in a grossly insulting way: the composer was dismissed literally "with a kick in the arse", administered by the archbishop's steward, Count Arco. Mozart decided to settle in Vienna as a freelance performer and composer.^[50]
The quarrel with Colloredo was more difficult for Mozart because his father sided against him. Hoping fervently that he would obediently follow Colloredo back to Salzburg, Mozart's father exchanged intense letters with his son, urging him to be reconciled with their employer. Mozart passionately defended his intention to pursue an independent career in Vienna. The debate ended when Mozart was dismissed by the archbishop, freeing himself both of his employer and of his father's demands to return. Solomon characterizes Mozart's resignation as a "revolutionary step" that significantly altered the course of his life.^[51]

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,^[50] and he soon "had established himself as the finest keyboard player in Vienna".^[50] 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",^[50] 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.^[52]
