Sergei Prokofiev’s Violin Sonata No. 2 in D Major, Op. 94a, was based on the composer’s own Flute Sonata in D, Op. 94, written in 1942 but arranged for violin in 1943 when Prokofiev was living in Perm in the Ural Mountains, a remote shelter for Soviet artists during the Second World War. Prokofiev transformed the work into a violin sonata at the prompting of his close friend, the violinist David Oistrakh. It was premiered on 17 June 1944 by David Oistrakh and Lev Oborin.
