Notes

The Ionian mode is more commonly called "the major scale" (and is the most commonly used major scale)
The Aeolian mode is commonly called "the natural minor scale" (and is the most commonly used minor scale)
Lydian, Ionian, & Mixolydian are considered major modes because their "I chord" is major.
Dorian, Aeolian, & Phrygian are considered minor modes because their "I chord" is minor.
The Locrian mode is so dissonant that it is usually unusable.
