C♯ Enigmatic

C♯ · D · E♯ · G · A · B · B♯

Invented by Verdi as a compositional puzzle, C♯ Enigmatic rises through a flat second, major third, flat fifth, flat sixth, flat seventh, and major seventh — an asymmetric sequence that belongs to no conventional key. It resists functional harmony almost by design. A curiosity worth exploring for genuinely unusual melodic shapes.
