This Rondo was written around the same time as the Piano Concertos in A major (KV 488) and c minor (KV 491). in the course of the work, a theme from the third movement of the Piano Quartet in g minor (KV 478) is taken up and further developed. in spite of its considerable length and its musical depth the work was apparently not published during the composer's lifetime. The dedication, "Pour Mad:selle Charlotte de W..." (the rest is indecipherable) is an enigma. No. matter which lady Mozart had in mind, this rondo is today one of his best loved and most played piano works.
