Properties of Greek Modes

Greek modes have really interesting properties

If we take the seventh chords of the major scale, we would get Imaj7 ii7 iii7 IVmaj7 V7 vii7 viiø7. We can order this by the circle of fifths. In particular, we will get the table below:

Ionian IVmaj7 Imaj7 V7 ii7 vi7 iii7 viiø7

Notice how it is in the order of chord qualities. When we go to Mixolydian, our seventh turns flat. Four things happen:

  1. the diminished chord’s root goes down a semitone, turning it into a major seventh chord.
  2. the third of the dominant chord goes minor, turning to a minor seventh chord.
  3. the fifth of the last minor seventh chord go flat, turning it to a half diminished chord.
  4. the seventh of the last major seventh chord goes flat, turning it to a dominant seventh chord.

If we were to reorder by the circle of fifths, we get a familiar pattern.

Mixolydian bVIImaj7 IVmaj7 I7 v7 ii7 vi7 iiiø7
Ionian IVmaj7 Imaj7 V7 ii7 vi7 iii7 viiø7

We can repeat the process forward and backwards for every mode. We get the final table here:

Locrian bVmaj7 bIImaj7 bVI7 biii7 bvii7 iv7 iø7
Phrygian bIImaj7 bVImaj7 bIII7 bvii7 iv7 i7 vø7
Aeolian bVImaj7 bIIImaj7 bVII7 iv7 i7 v7 iiø7
Dorian bIIImaj7 bVIImaj7 IV7 i7 v7 ii7 viø7
Mixolydian bVIImaj7 IVmaj7 I7 v7 ii7 vi7 iiiø7
Ionian IVmaj7 Imaj7 V7 ii7 vi7 iii7 viiø7
Lydian Imaj7 Vmaj7 II7 vi7 iii7 vii7 #ivø7

Is this useful? Not really. But I find it interesting that:

  • The tonic note forms the longest axis. Makes sense because the tonic is always ever.
  • Every note in Lydian eventually gets a half diminished version.
  • Every new note in the right column eventually lands a spot in Locrian
  • Most chords are actually fully minor chords.
