About
Wolfgang Amadeus Mozart is the central figure of the Classical era and, for most listeners and musicians, the most naturally gifted composer who has ever lived. Born in Salzburg to a musician father who was also his teacher and impresario, he began composing at age five and performing across the courts of Europe at age six. He spent most of his adult life in Vienna in a state of financial insecurity, producing in his final decade a stream of masterpieces in every genre — opera, symphony, concerto, chamber music, sacred music — that has never been equalled in quality or quantity in so short a time. He died at thirty-five.
Compositional Style
Mozart's compositional style is characterized above all by a perfect balance of opposites that no other composer has consistently maintained: melody and counterpoint, freedom and form, lightness and depth, comedy and tragedy. His music appears spontaneous and effortless — and was often written at extraordinary speed — yet it is architecturally flawless. Sonata form movements unfold with a logical necessity that feels like the only possible shape they could have taken; arias capture complex emotional states in melodies that feel discovered rather than invented.
His melodic genius is of a different order from Handel's (more harmonically adventurous) and Vivaldi's (more structurally integrated). A Mozart melody is always embedded in its harmonic context; it cannot be separated from its bass and inner voices without loss. The famous theme of the Piano Sonata in A major, K. 331 is a simple minuet tune, but its inner voice motion is quietly complex, and it is this complexity that gives the theme its warmth.
His harmonic language is deeply chromatic for its period: he uses diminished seventh chords, augmented sixths, and Neapolitan harmony with a fluency and dramatic purposefulness that his contemporaries rarely matched. The chromatic descents in the first movement of the Piano Sonata in C minor, K. 457, or the extraordinary harmonic sequences in the development section of the "Jupiter" Symphony's first movement, are moments when his harmonic thinking exceeds anything his era demanded or expected.
His counterpoint, learned from Bach through Baron van Swieten's circle in Vienna, is used strategically rather than systematically. The finale of the "Jupiter" Symphony, which combines five independent themes in a concluding stretto, is the most brilliant display of counterpoint in the Classical repertoire. In the operas, the ensembles — particularly the Act II finale of Le nozze di Figaro — are masterpieces of simultaneous dramatic and musical counterpoint.
Orchestration
Mozart's orchestration is the Classical standard — strings, pairs of woodwinds, horns, trumpets and drums — but within this framework he achieves effects of extraordinary subtlety and emotional precision. His assignment of melodic material to the winds is more independent and characterful than Haydn's early practice: the clarinet, which he used extensively from 1781 onward (after discovering Anton Stadler's playing in Vienna), became for him an instrument of special emotional weight, associated with the warmth and vulnerability of the human voice.
His late symphonies (Nos. 38–41) demonstrate the full maturity of his orchestral thinking. The orchestration of the "Prague" Symphony No. 38 is notably dark, with a prominent role for the lower strings and winds that gives the music a density unusual for the period. The "Jupiter" Symphony No. 41 uses its wind writing with chamber-music delicacy in the slow movement and with fugal brilliance in the finale.
In his piano concertos — twenty-seven of them, spanning his entire mature career — he develops a new kind of orchestral-soloist relationship. Unlike the Baroque concerto's tutti/solo dialogue, Mozart's concerto movements feature an orchestra that accompanies, completes, and sometimes contradicts the soloist in a continuous conversation. The strings support or comment; the winds add color and articulate the harmonic structure; the piano ranges freely over and through this texture. The slow movement of the Piano Concerto No. 21 in C major, K. 467 — with its steady pizzicato bass, murmuring flute, and singing piano line above muted strings — is one of the most perfectly realized orchestral textures in music.
In his operas — Don Giovanni, Le nozze di Figaro, Così fan tutte, Die Zauberflöte, La clemenza di Tito — the orchestration is intimately tied to dramatic function. The trombones that enter with the Commendatore's ghost in Don Giovanni are a famous example: their archaic, solemn sonority marks the boundary between the human world and the supernatural. The bassoon that doubles the bass voice in the same scene adds an almost comic gravity.
Key Works
- Symphony No. 41 in C major ("Jupiter"), K. 551 (1788)
His last symphony; the finale's five-theme fugal stretto is the summit of Classical counterpoint.
- Le nozze di Figaro, K. 492 (1786)
His first and greatest comic opera; a masterclass in ensemble writing and dramatic psychology.
- Don Giovanni, K. 527 (1787)
Opera that defies genre — simultaneously comedy and tragedy; the overture's D-minor opening is electrifying.
- Piano Concerto No. 20 in D minor, K. 466 (1785)
The first of his minor-key concertos; stormy and proto-Romantic, loved by Beethoven.
- Requiem in D minor, K. 626 (1791)
Left incomplete at his death; the Lacrimosa is among the most moving things he ever wrote.
- String Quintet in G minor, K. 516 (1787)
Often considered his most personal chamber work; the slow movement is one of infinite tenderness.
- Piano Sonata in A major, K. 331 (1783)
Includes the beloved "Alla Turca" finale; the theme and variations first movement is a model of Classical variation writing.
- Clarinet Concerto in A major, K. 622 (1791)
His final concerto; a valedictory work of intimate beauty written for his friend Stadler.
Influence
Mozart's influence is universal and largely inimitable — composers tend to absorb specific techniques rather than his totality. Beethoven studied his piano concertos and learned from their orchestral-soloist relationship. Schubert absorbed his lyrical chamber-music style. His operas remained the standard against which all subsequent opera was measured, and Wagner's conception of music drama grew partly from reaction to what Mozart's operas had achieved. Brahms said he despaired of writing a symphony after hearing Mozart's.
