Wolfgang Amadeus Mozart_Depature to Vienna

1781: Departure to Vienna

In January 1781, Mozart's opera Idomeneo premiered with "considerable success" in Munich. The following March the composer was summoned to Vienna, where his employer, Archbishop Colloredo, was attending the celebrations for the accession of Joseph II to the Austrian throne. Mozart, fresh from the adulation he had earned in Munich, was offended when Colloredo treated him as a mere servant, and particularly when the archbishop forbade him to perform before the Emperor at Countess Thun's for a fee equal to half of his yearly Salzburg salary. The resulting quarrel 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 ass", administered by the archbishop's steward, Count Arco. In Vienna, though, Mozart had become aware of some rich opportunities, and he decided to settle there as a freelance performer and composer.

The quarrel with the archbishop went harder for Mozart because his father sided against him. Hoping fervently that he would obediently follow Colloredo back to Salzburg, Leopold exchanged intense letters with his errant son, urging him to be reconciled with their employer; but Wolfgang passionately defended his intention to pursue an independent career in Vienna. The debate ended when Mozart was dismissed, freeing him from the demands of an oppressive employer and of an over-solicitous father. Solomon characterizes Mozart's resignation as a "revolutionary step", and it greatly altered the course of his life.

Early Vienna years

Mozart's new career in Vienna began well. He performed often 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 to enormous acclaim. The work was soon being performed "throughout German-speaking Europe", and fully 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 father, Fridolin, had died, and the Webers were now taking in lodgers to make ends meet. Aloysia, who had earlier rejected Mozart's suit, was now married to the actor Joseph Lange, and Mozart's interest shifted to the third daughter, Constanze. The couple were married on 4 August 1782, eventually securing Leopold's "grudging consent".In the marriage contract, Constanze "assigns to her bridegroom five hundred gulden which [...] the latter has promised to augment with one thousand gulden", with the total "to pass to the survivor". Further, all joint acquisitions during the marriage were to remain the common property of both.

The couple had six children:

•Raimund Leopold (17 June – 19 August 1783)
•Karl Thomas Mozart (21 September 1784 – 31 October 1858)
•Johann Thomas Leopold (18 October – 15 November 1786)
•Theresia Constanzia Adelheid Friedericke Maria Anna (27 December 1787 – 29 June 1788)
•Anna Maria (died soon after birth, 25 December 1789)
•Franz Xaver Wolfgang Mozart (26 July 1791 – 29 July 1844)

In the course of 1782 and 1783 Mozart became intimately acquainted with the work of Johann Sebastian Bach and George Frideric Handel as a result of the influence of Gottfried van Swieten, who owned many manuscripts of the Baroque masters. Mozart's study of these scores inspired compositions in Baroque style, and later had a powerful influence on his own personal musical language: for example in fugal passages in Die Zauberflöte ("The Magic Flute") and the finale of Symphony No. 41.

In 1783, Wolfgang and Constanze visited his family in Salzburg. Leopold and Nannerl were, at best, only polite to Constanze; but the visit at least prompted the composition of one of Mozart's great liturgical pieces, the Mass in C minor. Though not completed, it was premiered in Salzburg, with Constanze singing a solo part.

Mozart met Joseph Haydn in Vienna, and the two composers became friends (see Haydn and Mozart). When Haydn visited Vienna, they sometimes played together in an impromptu string quartet. Mozart's six quartets dedicated to Haydn (K. 387, K. 421, K. 428, K. 458, K. 464, and K. 465) date from the period 1782 to 1785, and amount to a carefully considered response to Haydn's Opus 33 set from 1781. He stood in awe of Mozart, whose sister recorded that in 1781 Haydn told the visiting Leopold: "I tell you before God, and as an honest man, your son is the greatest composer known to me by person and repute, he has taste and what is more the greatest skill in composition."

From 1782 to 1785 Mozart mounted concerts with himself as soloist, presenting three or four new piano concertos in each season. Since space in the theaters was scarce, he booked unconventional venues: a large room in the Trattnerhof (an apartment building); and the ballroom of the Mehlgrube (a restaurant). The concerts were very popular, and the concertos he premiered at them are still firm fixtures in the repertoire. Solomon writes that during this period Mozart created "a harmonious connection between an eager composer-performer and a delighted audience, which was given the opportunity of witnessing the transformation and perfection of a major musical genre".

With substantial returns from his concerts and elsewhere, he and Constanze adopted a rather plush lifestyle. They moved to an expensive apartment, with a yearly rent of 460 florins. Mozart also bought a fine fortepiano from Anton Walter for about 900 florins, and a billiard table for about 300. The Mozarts sent their son Karl Thomas to an expensive boarding school, and kept servants. Saving was therefore impossible, and the short period of financial success did nothing to soften the hardship the Mozarts were later to experience.

On 14 December 1784, Mozart became a Freemason, admitted to the lodge Zur Wohltätigkeit ("Beneficence"). Freemasonry played an important role in the remainder of Mozart's life: he attended many meetings, a number of his friends were Masons, and on various occasions he composed Masonic music.
