Wolfgang Amadeus Mozart (1756-1791) was born in Salzburg in Austria, the son of

Leopold, Kapellmeister to the Prince-Archbishop of Salzburg. By the age of three
he could play the piano, and he was composing by the time he was five; minuets
from this period show remarkable understanding of form. Mozart's elder sister

Maria Anna (best known as Nannerl) was also a gifted keyboard player, and in

1762 their father took the two prodigies on a short performing tour, of the
courts at Vienna and Munich. Encouraged by their reception, they embarked the
next year on a longer tour, including two weeks at Versailles, where the
children enchanted Louis XV. In 1764 they arrived in London. Here Mozart wrote
his first three symphonies, under the influence of Johann Christian Bach,
youngest son of Johann Sebastian, who lived in the city. After their return to

Salzburg there followed three trips to Italy between 1769 and 1773. In Rome

Mozart heard a performance of Allegri's Misere; the score of this work was
closely guarded, but Mozart managed to transcribe the music almost perfectly
from memory. On Mozart's first visit to Milan, his opera Mitridate, r? di Ponto
was successfully produced, followed on a subsequent visit by Lucia Silla. The
latter showed signs of the rich, full orchestration that characterizes his later
operas. A trip to Vienna in 1773 failed to produce the court appointment that
both Mozart and his father wished for him, but did introduce Mozart to the
influence of Haydn, whose Sturm und Drang string quartets (Opus 20) had recently
been published. The influence is clear in Mozart's six string quartets,

K168-173, and in his Symphony in G minor, K183. Another trip in search of
patronage ended less happily. Accompanied by his mother, Mozart left Salzburg in

1777, travelling through Mannheim to Paris. But in July 1778 his mother died.

Nor was the trip a professional success: no longer able to pass for a prodigy,

Mozart's reception there was muted and hopes of a job came nothing. Back in

Salzburg Mozart worked for two years as a church organist for the new
archbishop. His employer was less kindly disposed to the Mozart family than his
predecessor had been, but the composer nonetheless produced some of his earliest
masterpieces. The famous Sinfonia concertante for violin, violo and orchestra
was written in 1780, and the following year Mozart's first great stage work, the
opera Idomeneo, was produced in Munich, where Mozart also wrote his Serenade for

13 wind instruments, K361. On his return from Munich, however, the hostility
brewing between him and the archbishop came to a head, and Mozart resigned. On
delivering his resignation he was verbally abused and eventually, physically
ejected from the archbishop's residence. Without patronage, Mozart was forced to
confront the perils of a freelance existence. Initially his efforts met with
some success. He took up residence in Vienna and in 1782 his opera Die Entf?hrung
aus dem Serail (The abdication from the Seraglio) was produced in the city and
rapturously received. The same year in Vienna's St Stephen's Cathedral Mozart
married Constanze Weber. Soon afterwards he initiated a series of subscription
concerts at which he performed his piano concertos and improvised at the
keyboard. Most of Mozart's great piano concertos were written for these
concerts, including those in C, K467, A, K488 and C minor, K491. In these
concertos Mozart brought to the genre a unity and diversity it had not had
before, combining bold symphonic richness with passages of subtle delicacy. In

1758 Mozart dedicated to Haydn the six string quartets that now bear Haydn's
name. Including in this group are the quartets known as the Hunt, which make use
of hunting calls, and the Dissonance, which opens with an eerie succession of
dissonant chords. Overwhelmed by their quality, Haydn confessed to Leopold

Mozart, 'Before God and as an honest man I tell you that your son is the
greatest composer known to me either in person or by name.' The pieces are
matched in excellence in Mozart's chamber music output only by his String

Quintets, outstanding among which are those in C, K515, G minor, K516 and D,

K593. Also in 178 Mozart and Lorenzo da Ponte collaborated on the first of a
series of operatic masterpieces. Le nozze di Figaro (The Marriage of Figaro) was
begun that year and performed in 1786 to an enthusiastic audience in Vienna and
even greater acclaim later in Prague. In 1787 Prague?s National Theatre saw the
premiere of Don Giovanni, a moralizing version of the Don Juan legend in which
the licentious nobleman receives his comeuppance and descends
