Piano Sonata No. 8

Sergei Prokofiev's Piano Sonata No. 8 in B major, Op. 84 is a sonata for solo piano, the third and longest of the three "war sonatas", with performances typically lasting around 30 minutes. He completed it in 1944 and dedicated it to his partner Mira Mendelson, who later became his second wife. The sonata was first performed on 30 December 1944, in Moscow, by Emil Gilels. Movements The sonata has three movements. I. Andante dolce — Allegro moderato The movement begins with a lyrical theme. The key is B major, but the sense of tonality is weak due to Prokofiev's frequent modulations to remote keys. Next is a theme in G minor that goes through a series of modulations which prepares the development section. The development section is tonally unstable and propelled by motoric rhythms. Another theme emerges, leading into a reprise of the first theme, followed by a truncated reprise of the development section, this time in B-flat minor. The movement ends in B major.
