Harmonic Minor vs. Harmonic Major

Both of these start on C, and both already carry a flat sixth and a raised seventh - the same augmented-second gap between them, reached from opposite directions (see Minor vs. Harmonic Minor and Major vs. Harmonic Major). The only thing left to separate them is the third.

The wheel makes the difference positional rather than verbal: the third-degree wedge sits one wedge further clockwise in Harmonic Major, and the spoke drawn from the center recolors to the interval that degree now forms with the tonic. Everything else on the two wheels is identical.

That single degree is the last mile between them: Harmonic Minor's flat third is what makes it read as minor at all, and Harmonic Major's natural third is what keeps it major despite the borrowed flat sixth. Everything else - the augmented second, the leading tone - is already identical. Reading it is one thing; the difference is much more obvious held under a drone, which is what the links under each figure are for.
