D 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:

D

I

E♭

bII

F♯

III

G♯

#IV

B

VI

C

bVII

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

How to play D prometheus neapolitan on guitar

Open D serves as a root, and open B lands on the major sixth, so a two-string pedal is ready before anything gets fretted. Fretted roots stack up at the 3rd fret, the 5th, and the 10th, which lets you change octave without leaving the shape. First box stretches to the 14th fret. An augmented second lives inside this fingering, so one wide reach per octave has to be planned.
