Clara Wieck, who later became the wife of Robert Alexander Schumann, is known as a pianist and composer. This Impromptu begins with its first movement, featuring a simple motif composed by Clara in the opening right-hand part, while the bass presents the C-F-G-C phrase, which Schumann himself used in the finale of his unfinished Symphony in G minor, a study piece. The work then proceeds in the form of 10 subsequent variations. The themes of these variations vary, sometimes being Clara's melody and sometimes Schumann's four-note phrase, and the piece progresses in an improvisatory manner. Although the beginning of the piece is written quite simply, it gradually becomes more complex, incorporating many somewhat difficult passages, making it a rather challenging work. Perhaps for this reason, it is rarely performed today. It was composed in 1832, and a revised edition with some minor alterations was completed the following year.
