About the G flat Prometheus Neapolitan scale
G flat 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♭, G, B♭, C, E♭, and E. The formula is H 1½ W 1½ H W. It is the fourth mode of C Blues Diminished.
An unfretted guitar already sounds E and G from the key. On guitar, the deepest G♭ within reach is the 2nd fret of the low E string. Placed at the second fret, a capo lets G♭ Prometheus Neapolitan be played with E-shape fingerings.
