Mozart

From prodigy to independent composer

Johannes Chrysostomus Wolfgangus Theophilus Mozart was born in Salzburg on 27 January 1756, the son of violinist, composer and pedagogue Leopold Mozart and Anna Maria Pertl. Only Wolfgang and his elder sister Maria Anna “Nannerl” survived infancy. Leopold recognized the children’s gifts early and organized extensive tours that exposed Wolfgang to courts, theatres, churches and leading musicians across Europe.

The journeys were not merely displays of prodigious talent. They formed a practical education in international styles. Mozart heard and absorbed Italian opera, Mannheim orchestral writing, Parisian public concert culture, London symphonic and keyboard traditions, and the contrapuntal legacy he later encountered more deeply in Vienna.

After years as a Salzburg court musician, Mozart broke with Archbishop Colloredo in 1781 and established himself in Vienna as a freelance performer, teacher and composer. This move created artistic freedom but also financial instability. His Vienna decade produced many of his greatest piano concertos, chamber works, symphonies and operas.

Why Mozart remains central

Salzburg childhood and Grand Tour: 1756–1766

Mozart began keyboard study at an extraordinarily early age under Leopold. The family travelled to Munich and Vienna in 1762, then undertook the great European tour of 1763–66 through German courts, Brussels, Paris, London, the Netherlands and Switzerland. In London Mozart met Johann Christian Bach, whose galant style and concerto writing left a lasting impression.

During these years Mozart composed keyboard pieces, sonatas and early symphonies while learning to write for public occasions and specific performers. His prodigy career placed him inside aristocratic networks but also subjected him to exhausting travel and repeated illness.

Italy and Salzburg service: 1769–1777

Three Italian journeys between 1769 and 1773 immersed Mozart in opera seria and Italian instrumental culture. He received honours in Bologna and Milan and wrote stage works including Mitridate, re di Ponto and Lucio Silla. Back in Salzburg he served the prince-archbishop’s court, composing symphonies, serenades, sacred music, concertos and dramatic works.

His relationship with Salzburg employment became increasingly restrictive. Mozart wanted a career equal to his ambitions and repeatedly sought opportunities elsewhere.

Mannheim and Paris: 1777–1779

Travelling with his mother, Mozart sought a permanent position in Mannheim and Paris. Mannheim’s celebrated orchestra influenced his orchestral imagination, while his relationship with the Weber family—especially the young singer Aloysia Weber—became personally important. No secure appointment resulted.

His mother died in Paris on 3 July 1778, a severe personal blow. Mozart nevertheless produced important works during the journey, including the Paris Symphony and music written for Mannheim and Paris performers. He returned reluctantly to Salzburg in 1779.

Idomeneo and the break with Salzburg: 1780–1781

The Munich commission for Idomeneo, premiered in January 1781, gave Mozart an opportunity to combine Italian opera seria, French-influenced choral spectacle and a highly developed orchestral language. Soon afterward, conflict with Archbishop Colloredo came to a head in Vienna. Mozart was dismissed from Salzburg service and chose to remain in the imperial capital.

Vienna: performer, teacher and composer, 1781–1786

Mozart quickly established himself as a celebrated pianist and teacher. He married Constanze Weber on 4 August 1782. Die Entführung aus dem Serail was a major success, while private encounters with the music of Bach and Handel through Baron van Swieten stimulated a renewed interest in counterpoint.

The mid-1780s were the high point of Mozart’s subscription concerts and piano concertos. Works such as K. 449, 450, 451, 453, 456, 459, 466, 467, 482, 488 and 491 explore an extraordinary range of tonal and dramatic possibilities. He also completed the six quartets dedicated to Haydn.

Opera maturity and Prague: 1786–1788

Le nozze di Figaro premiered in Vienna in 1786 and enjoyed especially strong success in Prague. The city’s enthusiasm led to Don Giovanni, premiered there in 1787. Mozart’s collaboration with librettist Lorenzo Da Ponte culminated in Così fan tutte in 1790.

In 1787 Mozart was appointed Imperial and Royal Chamber Composer, succeeding Gluck, though the post did not provide the stable income of a full Kapellmeister position. In 1788 he composed the last three symphonies, Nos. 39, 40 and 41, within a remarkably concentrated period.

Final years: 1789–1791

Changing concert conditions, war-related economic pressures and Mozart’s own household finances reduced the security of his Vienna career. Yet his final years were compositionally rich. In 1791 he wrote La clemenza di Tito, Die Zauberflöte, the Clarinet Concerto and the unfinished Requiem.

Mozart became seriously ill in late November and died shortly after midnight on 5 December 1791 at the age of thirty-five. The precise medical cause remains uncertain; sensational poisoning theories have no secure documentary basis.

Family and posthumous legacy

Constanze played an important role in preserving and promoting Mozart’s legacy, arranging memorial concerts, dealing with publishers and cooperating with early biographers. Two sons survived to adulthood: Karl Thomas and Franz Xaver Wolfgang.

The nineteenth century turned Mozart into an emblem of “natural genius,” sometimes obscuring the discipline, revision and professional calculation visible in his manuscripts and correspondence. Modern scholarship restores the complexity of the working composer behind the legend.

Melody, harmony and form

Mozart’s themes often sound spontaneous because phrase balance and harmonic pacing are exceptionally clear. Yet his mature works frequently complicate that clarity with chromatic detours, minor-mode shadows, delayed cadences and development of small motives.

Sonata procedures are flexible rather than formulaic. Operatic habits of contrast and dialogue enter instrumental music, while concerto form exploits the difference between public orchestral statement and the soloist’s more individual voice.

Opera and ensemble writing

Mozart’s operatic ensembles allow several characters to express conflicting intentions simultaneously without sacrificing formal coherence. The finales of Figaro and Don Giovanni are famous examples of accumulating dramatic complexity controlled through key, tempo, texture and recurring motives.

His orchestration is closely tailored to dramatic character. Winds acquire increasing independence in the mature operas, concertos and symphonies.

Counterpoint and older music

Through van Swieten’s circle Mozart studied works by Bach and Handel. This study intensified his contrapuntal writing in pieces such as the C minor Mass, the finale of the “Jupiter” Symphony and several chamber works. Learned style becomes part of Mozart’s own expressive language rather than a historical imitation.

Improvisation, performers and revision

Mozart was celebrated as an improviser at the keyboard. His concertos were often composed for his own performance, and surviving autographs sometimes leave room for embellishment or cadenzas. Other works were designed around specific voices or instrumentalists, such as Anton Stadler in the Clarinet Quintet and Concerto.

Autographs show both extraordinary fluency and real revision. The romantic myth that Mozart simply “wrote down finished music from his head” is an oversimplification.

Cataloguing and authenticity

The Köchel catalogue is not a simple list of “626 works.” Modern Mozart research distinguishes authentic works, doubtful attributions, arrangements, fragments, lost pieces and newly identified items. The 2024 edition introduced additional catalogue entries and rationalized historical numbering without erasing familiar K numbers.
