Scriabin's early harmonic language was specially fond of the thirteenth dominant chord, usually with the 7th, 3rd, and 13th spelled in fourths. This voicing can also be seen in several of Chopin's works. According to Peter Sabbagh, this voicing would be the main generating source of the later Mystic chord. More importantly, Scriabin was fond of simultaneously combining two or more of the different dominant seventh enhancings, like 9ths, altered 5ths, and raised 11ths. However, despite these tendencies, slightly more dissonant than usual for the time, all these dominant chords were treated according to the traditional rules: the added tones resolved to the corresponding adjacent notes, and the whole chord was treated as a dominant, fitting inside tonality and diatonic, functional harmony.
