Sergei Prokofiev's Piano Sonata No. 6 in A major, Op. 82 (1940) is a sonata for solo piano, the first of the Three War Sonatas. The sonata was first performed on April 8, 1940 in Moscow.
- Allegro moderato
- Tempo di valzer lentissimo
1. Allegro moderato
The first movement introduces the main motto, which is somewhat tonally unstable because it is introduced in both A major and A minor. Thus, it already introduces the uncertainty of the work. Only at the beginning the movement is somewhat tonal. The greater part of it is dominated by grinding dissonances and atonality, further increasing the despair of the work. Throughout most of the piece, there is a lack of key signature.
The second movement has been described as having a march-like sound with staccato chords, the middle section being melodic.
3. Tempo di valzer lentissimo
The third movement is similar to a waltz, slower and romantic.
The closing movement is a rondo, containing material from the opening movement.
