The air (theme) of this set of variations is by A. L. Baudron. It was composed in Paris in 1778. Notably, Mozart composed a total of four sets of variations for piano in this year.

The theme consists of two parts, a first half and a second half, with the latter being slightly longer. Furthermore, in this set of variations, Mozart introduced a variation in a minor key (Variation 9). Among Mozart's variations, this is a relatively large-scale work, and he employs the technique of concluding the entire work with a restatement of the theme. Additionally, pairs of variations can be observed where the roles of the left and right hands are interchanged.
