D Messiaen's Mode #3
D · E · F · F♯ · G♯ · A · B♭ · C · C♯
The third of Messiaen's modes of limited transposition, D Messiaen's Mode #3 uses nine notes in a symmetrical pattern that repeats every major third. With so many notes it's closer to a colour field than a melodic scale. Best approached as a source of harmonic material for modern composition.
Left-handed
