Mozart’s Aria for Margarethe Marchand (K. 689) is a documented but now-lost vocal work, dated to Vienna in 1784. No music survives, leaving only its catalogue identity and a glimpse of Mozart’s ongoing, highly practical involvement with singers in his Viennese years.

The dedicatee is generally understood to be the soprano Maria Margarethe Marchand (later Danzi, 1768–1800), who was active in German musical circles a generation younger than Mozart [2]. In 1784 Mozart was deeply engaged with Vienna’s musical life—writing piano concertos for his own concerts and cultivating professional networks in which tailor-made vocal items could serve as auditions, favors, or Gelegenheitsstücke (occasional pieces) [3].

Musical Content

No notated musical content survives for K. 689, so its form, scoring, and text cannot be described from primary musical evidence. Although the work’s title calls it an “aria,” later summaries sometimes speculate about a small-scale vocal piece; the Mozarteum entry itself preserves only the basic identification and its lost status [1].
