Composed in Vienna in 1786. The theme of this set of variations is very short, consisting of an antecedent and a consequent phrase, each four measures long. The twelve variations derived from this brief theme are not merely rhythmic variations; they encompass pairs of variations where the roles of the left and right hands are interchanged, hand crossing, and polyphonic techniques, among other devices. Furthermore, the entire set of variations concludes with a restatement of the theme.
