Scale Notes & Info
Scale: C prometheus
Description: A six-note synthetic scale derived from Scriabin's Prometheus or mystic chord (for example C, F♯, B♭, E, A, D). Lacking a conventional 3rd or 7th, it produces an open, ambiguous sonority that has inspired modern classical and jazz composers seeking luminous, quartal, non-functional harmony.
Notes (pitch classes): C, D, E, Gb, A, A#
Intervals (formula): 1P, 2M, 3M, 4A, 6M, 7m
