About the Prometheus Scale
The notes are root, 2nd, 3rd, raised 4th, 6th and flat 7th. Scriabin built his mystic chord from these notes.
Almost every step is a whole step, so the scale sounds dreamy and has no strong pull to any note.
Play it over a dominant 7th chord with a #11, the same sound as Lydian dominant.
