Sergei Prokofiev's Piano Sonata No.
14, is a sonata for solo piano, written in 1912.
First published by P. Jurgenson in 1913, it was premiered on 5 February 1914 in Moscow with the composer performing.
[1][2] Prokofiev dedicated the work to his friend and fellow student at the St. Petersburg Conservatory, Maximilian Schmidthof, who committed suicide in 1913.
[3] Concert pianist Boris Berman has said of this sonata that it 'covers a huge emotional range: from Romantic lyricism to aggressive brutality'.
