How the formulas differ
Scale degrees are the key-independent way to compare two scales — these stay the same in every key, and they are what actually distinguishes one scale from another.
| Scale | Degrees |
|---|---|
| Natural Minor (Aeolian) | R · 2 · b3 · 4 · 5 · b6 · b7 |
| Harmonic Minor | R · 2 · b3 · 4 · 5 · b6 · 7 |
