Piano Sonata No.8 in B-flat major, Op. 84

The movement begins with a melancholy, and mysterious theme that wanders. The key is B♭ major but the sense of tonality is weak due to Prokofiev's frequent modulations to remote keys. After the theme ends, a development, reminiscent of the first movement of the Piano Sonata No.7, follows. Next is a more brooding theme in G minor which goes through a series of modulations as the music prepares for the development section. The development section is unstable and perpetuated by motoric rhythms.
