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

How to play E prometheus neapolitan on guitar

Open E rings as a root on the top and bottom strings, with the minor seventh on open D, so a pedal tone can hold while the hand works higher. Nut position doubles as position one, with fretted roots at the 2nd on the D string and the 5th on the B string. First shape ends at the 4th fret, which means shifts arrive quickly. A-shape barre waits at the 7th.
