About the G Prometheus Neapolitan scale

G Prometheus Neapolitan is used for impressionist and experimental writing. Think of it as the Prometheus scale with a flat second added.

Its notes are G, A, B, C, E, and E. The formula is H 1½ W 1½ H W. It is the fourth mode of C Blues Diminished.

E, G, and B are open guitar strings that sit inside the key, ready to drone under a riff. A guitarist finds the lowest G at the 3rd fret of the low E string. The first three frets carry a complete octave of G Prometheus Neapolitan, a genuine open-position shape.
