About the B flat Prometheus scale
B flat Prometheus is used for impressionist and mystical concert music. Think of it as the mystic chord of Scriabin turned into a scale, a raised fourth with no fifth. It is B♭ Whole Tone with the sixth raised.
Its notes are B♭, C, D, E, G, and G♯. The formula is W W W 1½ H W.
Also called Mystic Scale and Mystic Chord.
Three open-string notes belong to B♭ Prometheus, namely E, D, and G. On guitar, the deepest B♭ within reach is the 1st fret of the A string. The scale runs a complete octave from root to root inside the first three frets.
