Db prometheus neapolitan

The prometheus neapolitan scale darkens the prometheus scale by lowering its 2nd: root, flat 2nd, major 3rd, raised 4th, 6th, flat 7th. The Neapolitan flat 2nd adds a Phrygian shadow to an already floating whole-tone-ish set, giving lines an exotic snap right at the start of the scale. A niche but memorable color over altered dominants.

tip
  • Prometheus with a phrygian doorstep: open with b2 (D) against the root, then float through III, #IV (G), VI, bVII (B).
  • Over an altered dominant vamp on Db, the b2 (D) reads as a b9; the rest of the scale keeps the 13#11 shimmer.
  • Contrast the two 2nds across phrases: a prometheus line (natural II) answered by this scale's b2 (D) makes a two-scale hook.
  • With no 5th, keep the root sounding low; a bass pedal on Db is what keeps this scale legible.

How to play D♭ prometheus neapolitan on guitar

Tones ring on open D, G, and B, giving the minor second, augmented fourth, and minor seventh without a fretting hand. Roots wait at the 9th fret on the outer strings, so the barre and the lowest box coincide, and the shape closes at the 13th. B string keeps one at the 2nd fret. Capo at the 1st fret converts everything to C fingering, so the four-flat spelling never has to be read.
