Sheet music by Alexander Scriabin

Alexander Nikolayevich Scriabin was a Russian composer and pianist. Scriabin, who was influenced by Frédéric Chopin, composed early works that are characterised by tonal language. Later in his career, independently of Arnold Schoenberg, Scriabin developed a substantially atonal and much more dissonant musical system, which accorded with his personal brand of mysticism.[citation needed] Scriabin was influenced by synesthesia, and associated colours with the various harmonic tones of his atonal scale, while his colour-coded circle of fifths was also influenced by theosophy. He is considered by some to be the main Russian Symbolist composer.
