Editing Hexatonic scale (section)

==Prometheus scale==
{{Main|Mystic chord}}
The Prometheus scale is so called because of its prominent use in [[Alexander Scriabin]]'s [[symphonic poem]] ''[[Prometheus: The Poem of Fire]]''.  Scriabin himself called this set of pitches, voiced as the simultaneity (in ascending order) C F{{music|sharp}} B{{music|flat}} E A D the "[[mystic chord]]". Others have referred to it as the "Promethean chord". It may be thought of as C Lydian-Mixolydian.

It can also be though as a triad pair: a minor triad and an augmented triad 1/2 step up. For example, A minor triad and B flat augmented triad.
