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 |
|---|---|
| Major (Ionian) | R · 2 · 3 · 4 · 5 · 6 · 7 |
| Mixolydian | R · 2 · 3 · 4 · 5 · 6 · b7 |
Notes in common
