Alexander Scriabin (6 January 1872 – 27 April 1915) was a late 19th Century Romantic and post-tonal composer of various piano and symphonic works. His career spanned the influences of Frederic Chopin and Arnold Schoenberg; Scriabin fondly referred to these composed in much of his output. He is also known for his colour-pitch synesthesia (a neurological condition where the individual experiences colours when certain pitches are heard), where he assigned specific colours to keys ordering in the circle of fifths.
