About the Enigmatic Scale

The notes are root, flat 2nd, 3rd, raised 4th, raised 5th, raised 6th and 7th. Verdi used it in his Ave Maria.

The flat 2nd and the 7th close in on the root. Between them the scale climbs in whole steps.

It sounds unstable, so phrases should end on the root.

Degree	Interval	Semitones	In A

Stack every other note of the scale and you get one chord on each note. These chords sound at home with the scale, so they make good progressions.
