Understanding Ab Lydian Dominant
Names and spellings
Ab Lydian Dominant is also called Ab Lydian ♭7, Ab acoustic, Ab overtone; every one of those names means exactly these notes.
Lydian dominant, Lydian ♭7, acoustic scale and overtone scale all name this one scale: a Lydian with a flattened seventh, which is the fourth mode of the melodic minor.
How it is built
On Ab the scale is Ab · Bb · C · D · Eb · F · Gb, following the step pattern W W W H W H W. It is mixolydian with a raised fourth, or lydian with a flattened seventh — both descriptions give the same seven notes.
It is also called the acoustic scale, because its notes approximate the first several partials of the overtone series more closely than any diatonic scale does.
How it is used
It is the standard scale over a 7♯11 chord and over a tritone substitution, where the raised fourth belongs to the key being substituted into.
Bartók used it extensively, and it is a staple of fusion writing for exactly the reason jazz likes it: bright without being resolved.
