About the E Scriabin scale
E Scriabin is used for impressionist and mystical concert music. Think of it as a five-note scale from the late, mystical harmony of Scriabin. It is E Major Pentatonic with the second lowered.
Its notes are E, F, G♯, B, and C♯. The formula is H 1½ 1½ W 1½.
Also called Major Pentatonic ♭2 and Vibhas.
E Scriabin uses two black keys on the piano, G♯ and C♯.
