F 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:

F

I

G

II

A

tip
  • This is the mystic chord as a scale: stack it in 4ths from F (root, #IV (B), bVII (Eb), 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 (Eb).
  • Resolve by half step: #IV (B) up to the 5th of the next chord, or bVII (Eb) down to its 3rd; the scale exits gracefully despite its float.

How to play F prometheus on guitar

Root sits at fret 1 on both E strings, keeping this key pressed up against the nut. Four inner strings ring scale tones open: A, D, G, and B, stacked as major third, major sixth, major second, and augmented fourth, so open-string texture is everywhere. One fret of capo swaps the whole thing to E fingering, which means barre work becomes optional. Box one ends at fret 5.
