Gb prometheus

The prometheus scale is Scriabin's mystic chord laid out as a six note scale: root, 2nd, major 3rd, raised 4th, 6th, flat 7th. It is the lydian dominant sound with the 5th removed, which unmoors it: bright, whole-tone leaning and never quite resolving. Use it over 7#11 or 13#11 chords, or for harmonically suspended interludes.

it consists of these notes and degrees:

tip
  • This is the mystic chord as a scale: stack it in 4ths from Gb (root, #IV (C), bVII (E), III, VI, II) to hear it as Scriabin voiced it.
  • Over a 13#11 chord, every note lands; with no 5th in the scale, nothing anchors, which is exactly the floating effect.
  • Treat II and VI as melodic pivots between the whole-tone-flavored lower notes and the dominant color of bVII (E).
  • Resolve by half step: #IV (C) up to the 5th of the next chord, or bVII (E) down to its 3rd; the scale exits gracefully despite its float.

How to play G♭ prometheus on guitar

Both E strings sit in the scale when open, spelled Fb at the minor seventh. A capo at fret 2 rewrites the key as E fingering, which means the 5-flat spelling stays on paper while your hands play something plainer. Uncapoed roots start at fret 2 on both E strings, so the E-shape barre stays low and available. Handover to position two comes at fret 6.
