The Impromptus, Op. 90, D. 899, 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. 142, though only the first two pieces were published during Schubert's lifetime. Together with the latter set, they have become a cornerstone of the piano repertoire.
The fourth and final Impromptu, in A♭ major, starts in A♭ minor and is characterized by cascading arpeggios and a chordal response.
The fourth Impromptu (Allegretto), in A♭ major, actually begins in A♭ minor, though this is written as A♭ major with accidentals. The opening theme consists of cascading arpeggios followed by murmuring chordal responses. These are repeated and developed, going through C♭ major and B minor before finally reaching A♭ major. There is a subordinate theme, accompanied by the arpeggio, varied with triplets. In the central section, in C♯ minor, the arpeggios are replaced by a chordal accompaniment. This section ventures into the major mode towards its conclusion, but reverts to the minor. The opening section is repeated and the work ends in A♭ major.
Performer: Olga Tverskaya (Fortepiano)
