18.5The seven modes

For reference:

1. Ionian
2. Dorian
3. Phrygian
4. Lydian
5. Mixolydian
6. Aeolian
7. Locrian

But do not memorize seven Greek names as our first task.

For practical jazz/pop piano, the most immediately useful are:

Ionian / major

Dorian

Mixolydian

Aeolian / natural minor

and later:

Lydian
