Harmonic Minor vs. Hungarian Minor

Both of these start on C, and both keep the raised seventh that gives Harmonic Minor its pull back to the tonic.

The wheel makes the difference positional rather than verbal: the fourth-degree wedge sits one wedge further clockwise in Hungarian Minor, 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 adds a second stretched, augmented-second gap to a scale that already has one: alongside the wide step between the flat sixth and the leading tone, Hungarian Minor opens a matching one between the raised fourth and the fifth, which is what gives it its dramatic, folk-tinged color. 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.
