B 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:

I

II

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

How to play B prometheus on guitar

Root and minor seventh ring open here, on the B and A strings, so the drone pair costs nothing. A-shape barre follows at fret 2 and the E-shape at fret 7, putting both classic root anchors in the first half of the neck. Two frets of capo turn the key into A fingering, which lets open grips absorb the 4 sharps. Shapes change over at fret 11.
