What It Is

The 4th mode of melodic minor (ascending/jazz form) - Lydian with a flatted 7th, combining a raised 4th with a dominant-quality seventh chord. Notes: A#, B#, C##, D##, E#, F##, G#.

How It Functions

Matches the notes of a dominant 7#11 chord; used over dominant chords that resolve in ways other than a plain V-I, especially tritone substitutions.

Mood & Character

Bright but unresolved - a floating, jazzy dominant color, less tense than a plain altered dominant scale.
