Sergei Prokofiev's Piano Sonata No. 9 in C major, Op. 103 (1947) is a sonata for solo piano composed in 1947 and consists of four movements.
 The sonata was dedicated to Sviatoslav Richter, a member of the Union of Soviet Composers, and by whom it was first performed on 21 April 1951 in Moscow.
Sergei Prokofiev's Piano Sonata No. 3 in A minor, Op. 28 (1917) is a sonata composed for solo piano, using sketches dating from 1907.

Sergei Prokofiev's Piano Sonata No. 2 in D Minor, Op. 14 (1912), is a sonata composed for solo piano.
 It was premiered on February 5, 1914 in Moscow with the composer performing.
 Prokofiev dedicated the work to his friend and fellow student at the St. Petersburg Conservatory, Maximilian Schmidthof, who committed suicide in 1913.
Visions fugitives, Op. 22, are a series of short piano pieces composed by Russian composer Sergei Prokofiev (1891–1953) between 1915 and 1917.
 They were premiered by Prokofiev on April 15, 1918 in Petrograd, Soviet Union.
 They were written individually, many for specific friends of Prokofiev's, and he originally referred to them as his "doggies" because of their "bite".
 In August 1917, Prokofiev played them for Russian poet Konstantin Balmont, and others, at the home of a mutual friend.
 Balmont was inspired to compose a sonnet on the spot, called "a magnificent improvisation" by Prokofiev who named the pieces ""Mimolyotnosti"" from these lines in Balmont's poem: ""In every fleeting vision I see worlds, Filled with the fickle play of rainbows"".
 A French-speaking friend at the house, Kira Nikolayevna, immediately provided a French translation for the pieces: "Visions Fugitives".
 Prokofiev often performed only a couple of them at a time as encores at the end of his performances.
Sergei Prokofiev's Violin Sonata No. 2 in D Major, Op. 94a (sometimes written as Op. 94bis), 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 violinist David Oistrakh.
 It was premiered on 17 June 1944 by David Oistrakh and Lev Oborin.
Sergei Prokofiev's Piano Sonata no. 5 in C major, Op. 38 (1923) and Op. 135 (revised 1952-53) is a sonata for solo piano.
 Prokofiev composed the sonata in Ettal, by the Bavarian Alps, and dedicated it to Pierre Souvtchinski, a musicologist and friend.
 Even though the revised version of the sonata has a new opus number, if one compares the two versions closely, there are few radical differences between the two, with most of the changes occurring in the last movement.
 This sonata was the only piano piece of this genre to be composed during his life outside of Russia.
Aram Il'yich Khachaturian ( ; Russian: Ара́м Ильи́ч Хачатуря́н ; Armenian: Արամ Խաչատրյան , "Aram Xačatryan"; ] ; 6 June [O.S. 24 May] 1903 1 May 1978) was a Soviet Armenian composer and conductor.
 He is considered one of the leading Soviet composers.
The Toccata in D minor, Op. 11 is a piece for solo piano, written by Sergei Prokofiev in 1912 and debuted by the composer on December 10, 1916 in Petrograd.

 Other composers of well-known toccatas include Maurice Ravel, Dmitri Kabalevsky and Aram Khachaturian.
Sergei Prokofiev's Piano Sonata No. 4 in C minor, Op. 29 (1917) is a sonata composed for solo piano.

Sergei Prokofiev set to work on his Piano Concerto No. 2 in G minor, Op. 16, in 1912 and completed it in 1913.
 But this concerto is lost; the score was destroyed in a fire following the Russian Revolution.
 Prokofiev reconstructed the work in 1923, two years after finishing his Third Concerto, and declared it to be “so completely rewritten that it might almost be considered [Concerto] No. 4”; indeed its orchestration has features that clearly postdate the 1921 concerto.
 Performing as solo pianist, Prokofiev premiered this surviving “No. 2” in Paris on 8 May 1924 with Serge Koussevitzky conducting.
 It is dedicated to the memory of Maximilian Schmidthof, a friend of Prokofiev's at the St. Petersburg Conservatory who had killed himself in 1913.
