Harmonic Minor = E F# G A B C D# = C Lydian #2 IIIh

The harmonic minor is considered a horizontal scale in the LCC. For instance, E harmonic minor has a flat-lying LT (C, as Chesper pointed out).

Classical theory/pedagogy uses the terms "leading note" and "leaning note" to denote tones that resolve up and those that resolve down.

In these terms, The major scale, or Ionian Mode, has it's M7 as a leading tone (resolves up to the tonic), and it's P4 as a leaning tone (resolves down to the M3 - a member of the tonic triad), both of which contribute to the HTG toward the tonic major triad.

The "natural minor" scale, or Aeolean Mode, has it's P4 as a leaning tone (this time resolving down to the m3 - a little weaker than to the M3), and a m6 as a leaning tone (resolves down to the P5), both creating HTG to the tonic minor triad.

To strengthen that HTG in minor keys, which classical music was all about, the Harmonic Minor scale was used - adding the M7 leading note to complement the force of the P4 and m6 to the tonic minor triad.

The Harmonic Major scale contains all three of these horizontally-charged intervals, but this time resolving to a tonic MAJOR triad - a more stable, final-sounding structure than the minor triad.

Like you said, motherlode, it's a very decisive scale for the horizontal side of things, since the intervals make it very clear whether your melody note is "here" or "there", and the polarity between separate, distinct "places" is at about it's maximum.

No ML, no different answers at all.

I agree that G Harmonic MAJOR = C Lydian Dim. [G Harmonic Major = C LD Vh ]

I was making the additional point that E Harmonic MINOR = C Lydian #2. [E Harmonic Minor = C L#2 IIIh ]
