Non più andrai

Non più andrai is the musical expression through which Mozart’s effortless invention transforms Salieri’s welcome march into a famous melody from The Marriage of Figaro. Its later returns give the tune sharply different meanings: it marks Salieri’s public defeat at the opera and becomes the accompaniment to Constanze Mozart’s furious, mocking dance at home.

From Welcome March to Operatic Melody

Mozart begins with the march’s opening measures, rejects an interval that does not work, and tests a different one. Building on the corrected interval and the military trumpet arpeggio associated with Non più andrai, he discovers the melody note by note in the high register. The improvisation grows into something virtually recognizable as the finished march, complete with increasingly showy flourishes and triumphant chords. Mozart laughs delightedly whenever he reaches the corrected interval, absorbed in the music and unaware of the insult his performance delivers to Salieri.

Salieri watches with a smile that conceals the affront. When Mozart finishes, an uncomfortable pause follows; Salieri says he must leave, while Mozart invites him to try a variation. The exchange turns the melody into more than a display of virtuosity: it is an unintentional appropriation of Salieri’s music, achieved so freely that Mozart appears not to recognize the injury.

Salieri Hears His March Again

At a performance of The Marriage of Figaro, Salieri describes himself as having taken his seat as a spectator after the opera was produced despite his efforts. He calls this a notable defeat, yet says he feels strangely excited as the audience hears Figaro sing the melody. The tune that began as Salieri’s welcome march has become, in his bitter formulation, his poor march arranged to delight the world forever. Its faint sound fades into applause, making the music’s public success immediate even as Salieri registers his personal loss.

Count Orsini-Rosemberg tells Salieri that the passage recalls his style, though he calls it more vulgar and less subtle; Johann von Strack emphatically agrees. Their remarks distinguish the melody’s recognizable connection to Salieri from the more conspicuous character of Mozart’s treatment. The march survives not as Salieri’s controlled composition but as music reshaped by the very rival whose success he has tried to obstruct.

A Tune Recast as Domestic Mockery

The melody returns in a markedly different setting when Constanze Mozart dances violently around the room to its rhythm. She invokes the need to dance to get warm, imitates a refined request for Mozart to write a contredanse, and sarcastically reduces his work to writing dances. She then sings the opening of Non più andrai furiously as she continues to dance.

Mozart cries out for her to stop and grabs her, turning to pleading and playful attempts to distract her, but Constanze pushes him away and keeps dancing. The scene makes the march’s recurrence pointedly unstable: music associated with an elegant public performance and Salieri’s defeated recognition now accompanies an angry domestic confrontation. Constanze uses its dance rhythm to mock Mozart’s occupation, while the tune’s persistence carries the earlier triumph into a scene of resentment and strain.
