Main Page | See live article | Alphabetical index Composer and theosophist Alexander Scriabin's so called mystic chord, actually called the synthetic chord by Scriabin, consists of the pitch classes: C, F#, Bb, E, A, D. An augmented fourth, diminished fourth, augmented fourth, and two perfect fourths. It is a quartal hexachord. Scriabin used this chord in what George Perle calls a pre-serial manner, producing harmonys, chordss, and melodies. However, unlike the twelve tone technique to which Perle refers, Scriabin did not use his synthetic chord as an ordered set. This article is from Wikipedia.
