Composed in Paris in 1778. Notably, Mozart composed a total of four sets of variations for piano in this year.

The theme consists of a first and second half, with the latter being slightly longer. Pairs of variations are observed, created by interchanging the roles of the left and right hands. Furthermore, sustained notes with trills and arpeggiated octaves are characteristically employed. Following the eighth variation, which features extremely short note values, the final variation stands out with its continuous passages of sequential progressions of chords and double stops. In this ninth variation, the work concludes by recalling the theme at the end.
