Alexander Nikolayevich Scriabin was a Russian composer and pianist. Scriabin's early work is characterised by a lyrical and idiosyncratic tonal language influenced by Frédéric Chopin. 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. Scriabin was influenced by synesthesia, and associated colors with the various harmonic tones of his atonal scale, while his color-coded circle of fifths was also influenced by theosophy. He is considered by some to be the main Russian Symbolist composer.
