What makes C♯ Enigmatic different
The enigmatic scale (1, ♭2, 3, ♯4, ♯5, ♯6, 7) was published in the 1880s as a harmonisation puzzle, and Verdi answered it with his Ave Maria. After the leap from ♭2 to 3 it climbs in whole steps through ♯4, ♯5 and ♯6, then closes on the tonic with two half steps. It has no perfect fourth or fifth, so it belongs to no major or minor family. The tonic is approached by a half step from each side, 7 below and ♭2 above, which is the only thing in the scale that points home.
