A work from 1789, by which time Mozart had become known as a popular opera composer, but his family's financial situation was steadily deteriorating. It is said that this set of variations was composed based on a work by the cellist Jean-Pierre Duport, whom Mozart met in Potsdam, where he had traveled hoping for a court position.

The theme effectively utilizes the characteristics of the clavier, with chords resonating beautifully. Initially, the development follows a typical pattern, employing sixteenth notes and arpeggios, while in the latter half, modulations and octaves gradually introduce a dynamic quality. This work originated from an improvisation performed before Duport; a gentle and delicate theme steadily expands, revealing a profound depth that startles the listener, before returning to the theme and concluding.
