What makes G Harmonic Major different
Harmonic major is the major scale with a lowered sixth, the one note that separates it from major. The ♭6 opens an augmented second between the sixth and seventh degrees, the same gap harmonic minor has, but over a major tonic. It changes the subdominant: the iv chord is minor while V stays major, so the minor iv to I cadence is built into the scale. Its ♭VI chord is augmented. On G, G Harmonic Major has E♭ where G Major has E; every other note is shared with G Major (G A B C D E F♯).
