The Piano Sonata in A minor D. 845 (Op. 42) by Franz Schubert is a sonata for solo piano, composed in May 1825.


I. Moderato

A minor. Sonata form (second theme in C major).

II. Andante poco moto

C major. Theme and variations.

(The first variation is not exact, as 4 measures are missing after measure 43 that would correspond to measures 20–23 of the theme.)

III. Scherzo: Allegro vivace - Trio: Un poco più lento

A minor - A major. Trio in F major.

IV. Rondo: Allegro vivace

A minor. Sonata-rondo (second theme in E minor - E major).

The first movement is in sonata form though with ambiguity over the material in the development and the beginning of the recapitulation.[1]

The second movement is in C major (relative key to A minor) variation form. Noted performers of the work in the 19th century included Hans von Bülow, who played the sonata in both Europe and the USA.[2]

The third movement is a scherzo in compound ternary form, where the main scherzo is essentially in sonata form. The main scherzo opens in the agitated A minor but ends jubilantly in A major (parallel key to A minor). The calmer and slower trio section is in F major, the submediant major to A minor (also the subdominant of the relative key to A minor). NO extra coda is present after the recapitulated main scherzo.

The fourth movement, in A minor, begins with a melancholic but light melody. This movement is in sonata rondo form with foreshortened recapitulation. The secondary subject in the exposition goes from E minor to E major, while that in the recapitulation goes from A minor to A major. This movement finally closes in A minor.

Daniel Coren has discussed the nature of the recapitulation in the first movement of this sonata.[3]
