A♯ Messiaen's Mode #7
A♯ · B · B♯ · C♯ · D♯ · D♯♯ · E♯ · F♯ · F♯♯ · G♯♯
The largest of Messiaen's modes of limited transposition, A♯ Messiaen's Mode #7 contains ten of the twelve notes in a symmetrical pattern repeating at the tritone. At that density it functions as texture rather than melody. Purely modern-composition material — there's little left for it to exclude.
