Eb 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.

it consists of these notes and degrees:

tip
  • Prometheus with a phrygian doorstep: open with b2 (E) against the root, then float through III, #IV (A), VI, bVII (Db).
  • Over an altered dominant vamp on Eb, the b2 (E) 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 (E) makes a two-scale hook.
  • With no 5th, keep the root sounding low; a bass pedal on Eb is what keeps this scale legible.

How to play E♭ prometheus neapolitan on guitar

Four open strings carry tones, the E pair spelled Fb at the minor second, open G at the major third, with open A supplying the augmented fourth. Nearest root is D string, 1st fret, so the opening box begins right at the nut. Capo the 1st fret, giving D fingering. Roots then climb through the 4th, 6th, and 8th frets, which means most of the low neck stays inside one shape before the 15th.
