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.
