The Seven Modes of the Major Scale Explained

Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian and Locrian - how they are built and how to hear them.

Modes have a reputation for being mysterious, but the idea is simple: if you take the seven notes of a major scale and treat a different note as "home", you get a different scale with its own mood. There are seven notes, so there are seven modes.

This lesson shows two ways to think about modes, the one note that gives each mode its character, how to rank them from bright to dark, and which chords bring each mode to life. You should already know the major scale and the natural minor scale.

The seven modes at a glance

Start with C major: C D E F G A B. Play those same white keys, but start and end on each note in turn:

DegreeModeNotes (from C major)Formula
1IonianC D E F G A B1 2 3 4 5 6 7
2DorianD E F G A B C1 2 b3 4 5 6 b7

6AeolianA B C D E F G1 2 b3 4 5 b6 b7
7LocrianB C D E F G A1 b2 b3 4 b5 b6 b7

Ionian is simply the major scale, and Aeolian is the natural minor scale. The other five are the "new" sounds.

A popular mnemonic for the order: I Don't Particularly Like Modes A Lot.

Two ways to think about modes

1. Relative (derivative) thinking

The table above is relative thinking: every mode is derived from a parent major scale. D Dorian is "C major starting on D". To find any mode, ask which major scale it belongs to:

  • Dorian is built on the 2nd degree, so E Dorian comes from D major: E F# G A B C# D.
  • Mixolydian is built on the 5th degree, so A Mixolydian comes from D major: A B C# D E F# G.
  • Lydian is built on the 4th degree, so Bb Lydian comes from F major: Bb C D E F G A.

This is fast for finding the notes, especially on guitar, where you can reuse major-scale shapes you already know.

The danger: if you play "C major shapes" over a D minor chord without hearing D as home, you are just playing C major. A mode only sounds like a mode when the harmony underneath establishes its root.

2. Parallel thinking

Parallel thinking compares every mode with the major or minor scale on the same root. All seven modes from C:

ModeNotes from CChange compared with...Parent major
C LydianC D E F# G A Bmajor with #4G major
C IonianC D E F G A B-C major
C MixolydianC D E F G A Bbmajor with b7F major
C DorianC D Eb F G A Bbnatural minor with natural 6Bb major
C AeolianC D Eb F G Ab Bb-Eb major
C PhrygianC Db Eb F G Ab Bbnatural minor with b2Ab major
C LocrianC Db Eb F Gb Ab BbPhrygian with b5Db major

Parallel thinking is how modes are heard: Mixolydian is "major with a flat 7", Dorian is "minor with a bright 6th". Use relative thinking to find notes quickly, and parallel thinking to understand the sound.

The characteristic note of each mode

Each mode has one note that sets it apart from its closest relative, major or natural minor. Emphasise this note in melodies and you will hear the mode clearly.

ModeTypeCharacteristic noteTypical mood
Lydianmajor#4floating, dreamy, bright
Ionianmajornatural 4 and major 7stable, familiar
Mixolydianmajorb7bluesy, earthy, rock
Dorianminornatural 6cool, soulful, hopeful minor
Aeolianminorb6sad, serious
Phrygianminorb2dark, Spanish-flavoured, tense
Locriandiminishedb5unstable, unresolved

Hear Dorian on its own. Listen especially for the B, the natural 6th, which a natural minor scale would flatten to Bb:

D Dorian Mode

D – E – F – G – A – B – C

Brightness order

If you arrange the modes on the same root from brightest to darkest, a neat pattern appears: each step lowers exactly one note by a half step.

  1. Lydian - 1 2 3 #4 5 6 7
  2. Ionian - lower the #4 to 4
  3. Mixolydian - lower the 7 to b7
  4. Dorian - lower the 3 to b3
  5. Aeolian - lower the 6 to b6
  6. Phrygian - lower the 2 to b2
  7. Locrian - lower the 5 to b5

After the #4 returns to 4, the notes are lowered in the order 7, 3, 6, 2, 5. On C that means Bb, Eb, Ab, Db, Gb - exactly the order of flats in key signatures, moving around the circle of fifths. Play all seven from the same root, one after another, and you will hear the music getting gradually darker.

Chords to play the modes over

A mode needs harmony that confirms its root and ideally contains its characteristic note. The basic match is the seventh chord built on that degree of the parent scale:

ModeMatching chord (on C)Good vamp to practise
IonianCmaj7C - F
DorianCm7, Cm6Cm - F (i - IV)
PhrygianCm7, or C7sus4 with b9 colourCm - Db (i - bII)
LydianCmaj7#11C - D (I - II)
MixolydianC7C - Bb (I - bVII)
AeolianCm7Cm - Ab - Bb (i - bVI - bVII)
LocrianCm7b5usually short, inside a ii - V in minor

The two-chord vamps are the key. A static chord alone is ambiguous; the second chord adds the characteristic note:

  • In Dorian, the IV chord is major (F in C Dorian contains A, the natural 6).
  • In Mixolydian, the bVII chord (Bb) contains the b7.
  • In Lydian, the II chord is major (D in C Lydian contains F#, the #4).

Try the Mixolydian vamp and improvise with G Mixolydian over it:

G Mixolydian vamp - G to F

  1. IG
  2. ♭VIIF
  3. IG
  4. ♭VIIF
G Mixolydian - the F natural is the characteristic b7

And a Dorian vamp: in the key of C major, the ii and V chords (Dm and G) make D sound like home if you start and end on Dm.

D Dorian vamp - Dm to G

  1. iiDm
  2. VG
  3. iiDm
  4. VG

On the bass

The bass decides which mode the listener hears. Over the same white-key chords, a bass line that keeps returning to D makes the music sound D Dorian; one that returns to G makes it G Mixolydian. So in a modal vamp, play the root on beat 1 of almost every bar, and use the characteristic note in fills and passing notes rather than holding it.

Bass line: root, fifth, octave and approach note

For D Dorian, the characteristic natural 6th (B) is on string 4, fret 7 or string 2, fret 9. Explore the mode across the neck:

Practice

  1. Write out all seven modes of G major (G Ionian, A Dorian, B Phrygian, C Lydian, D Mixolydian, E Aeolian, F# Locrian). Then write all seven modes starting on D using parallel thinking, and name each parent major scale.
  2. Record a one-chord drone or a two-chord vamp from the table, then improvise using only the matching mode. Land on the characteristic note on strong beats.
  3. Play the brightness order from one root (Lydian down to Locrian) slowly and sing along.
  4. Name the mode: a scale contains A B C# D E F# G and A is home. (Answer: A Mixolydian.)
