Though these works are often considered to be influenced by Scriabin's
synesthesia, a condition wherein one experiences sensation in one sense in response to stimulus in another, it is doubted that Alexander Scriabin actually experienced this. His color system, unlike most synesthetic experience, lines up with the
circle of fifths: it was a thought-out system based on Sir
Isaac Newton's Optics. Indeed, influenced also by his theosophical beliefs, he developed it towards what would have been a pioneering multimedia performance: his unrealized magnum opus
Mysterium was to have been a grand week-long performance including music, scent, dance, and light in the foothills of the
Himalayas that was to bring about the dissolution of the world in bliss.
In his autobiographical
Recollections, Sergei Rachmaninoff recorded a conversation he had had with Scriabin and
Nikolai Rimsky-Korsakov about Scriabin's association of colour and music. Rachmaninoff was surprised to find that Rimsky-Korsakov agreed with Scriabin on associations of musical keys with colours; himself skeptical, Rachmaninoff made the obvious objection that the two composers did not always agree on the colours involved. Both maintained that the key of D major was golden-brown; but Scriabin linked E-flat major with red-purple, while Rimsky-Korsakov favoured blue. However, Rimsky-Korsakov protested that a passage in Rachmaninoff's opera
The Miserly Knight supported their view: the scene in which the Old Baron opens treasure chests to reveal gold and jewels glittering in torchlight is written in D major. Scriabin told Rachmaninoff that "your intuition has unconsciously followed the laws whose very existence you have tried to deny."
While Scriabin wrote only a small number of
orchestral works, they are among his most famous, and some are frequently performed. They include three
symphonies, a
piano concerto (1896),
The Poem of Ecstasy (1908) and
Prometheus: The Poem of Fire (1910), which includes a part for a "
clavier à lumières", also known as the
Luxe, which was a
color organ designed specifically for the performance of Scriabin's symphony. It was played like a piano, but projected colored
light on a screen in the concert hall rather than sound. Most performances of the piece (including the premiere) have not included this light element, although a performance in
New York City in 1915 projected colours onto a screen. It has erroneously been claimed that this performance used the
colour-organ invented by English painter
A. Wallace Rimington when in fact it was a novel construction personally supervised and built in New York specifically for the performance by Preston S. Miller, the president of the Illuminating Engineering Society.
Scriabin's original colour keyboard, with its associated turntable of coloured lamps, is preserved in his apartment near the
Arbat in Moscow, which is now a museum dedicated to his life and works.
