Scriabin's Piano Sonata No. 2 in G-sharp minor, took five years for him to write. It was finally published in 1898, at the urging of his publisher. The piece is in two movements, with a style combining Chopin-like Romanticism with an impressionistic touch. The piece is widely appreciated and is one of Scriabin's most popular pieces.
