4 Impromptus, D.935, op. posth.142
The Impromptus, Op. posth. 142, D. 935, are a set of four impromptus for solo piano composed by Franz Schubert in 1827. They were written in the same year as the Impromptus, Op. 90, but were not published until 1839, more than a decade after his death. Together with the preceding set, they have become a cornerstone of the piano repertoire.
The first Impromptu in F minor follows the form of a sonata exposition. The second Impromptu in A♭ major is written in the standard minuet form. The third Impromptu in B♭ major is a theme with variations. Finally, the fourth Impromptu in F minor is highly virtuosic and the most technically demanding of the set. Due to their structural and thematic links, some envisioned the four Impromptus as parts of a multi-movement sonata, a conjecture which is subject of debate among musicologists and scholars.
