Db 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 Db (root, #IV (G), bVII (B), 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 (B).
  • Resolve by half step: #IV (G) up to the 5th of the next chord, or bVII (B) down to its 3rd; the scale exits gracefully despite its float.

How to play D♭ prometheus on guitar

One fret of capo moves this key onto C fingering, which means the 4-flat spelling never slows you down. Nearest root without it: B string, fret 2. Open G and open B keep contact with the scale, G sounding the augmented fourth and the B spelled as Cb. First shape runs to fret 13, so the position change lands past fret 12.
