In the ascending melodic minor mode, the third note of the scale is flattened. For example, C minor: C, D, Eflat, F, G, A, B, C.

In the descending melodic minor mode, the sixth and seventh notes are also flattened. C minor again: C, Bflat, Aflat, G, F, Eflat, D, C.

In the harmonic minor mode, the third and sixth notes are flattened in both ascending and descending modes. C minor yet again: C, D, Eflat, F, G, Aflat, B, C.

I hope this is helpful. 🙂

I understand this thanks! I think i’m going to pick harmonic minors for my scales! (thank God I have that choice)
