The Phrygian Chord Progression
The defining Phrygian move is i-bII. In E Phrygian, play Em and F major. Their roots are one semitone apart, and F is the flat second degree that gives the mode its characteristic pull toward E.
- 2 chords
- Em F
- flat 2 sits one semitone above the tonic

The progression
- i
- bII
Follow every voice
Em contains E-G-B. F major contains F-A-C. In root position, all three voices rise by scale step:
- E rises by semitone to F
- G rises by whole tone to A
- B rises by semitone to C
On the return, the pattern reverses. Parallel triads make the root semitone feel larger because every chord tone participates in the motion.
Keep E as the centre
The notes of E Phrygian are the white notes from E to E: E-F-G-A-B-C-D. They are also the notes of C major, so the collection alone does not establish E as home.
Use a low E drone, begin and end phrases on Em and let melodies settle on E or B. Avoid strong G7-C motion if E should remain central.
Compare three textures
| Texture | Sound to follow |
|---|---|
| E then F bass notes | root semitone |
| Em then F triads | parallel stepwise voices |
| F/E then Em | F rubbing directly against an E pedal |
F/E places the bII chord above the tonic bass. The simultaneous E-F minor second is more compressed than the alternating roots and can create a stronger dissonance.
A modal writing exercise
- Drone Ehold it for four bars.
- Alternate Em and Fkeep one chord per bar.
- Write with E-F-Gmake flat 2 audible in the melody.
- Remove F for one phrasenotice how quickly the specific Phrygian identity weakens.
- Return through F-Emuse the semitone as the final modal gesture.
Relation to the Andalusian cadence
Am-G-F-E contains the same F-E semitone at its end. From an E-centred perspective, F-E is bII-I. From an A-minor perspective, E or E7 is V leading back to Am.
The surrounding phrase decides whether the semitone closes on E or prepares A minor.
When it is useful
Use i-bII when a modal section needs a compact, unmistakable Phrygian identity. Tempo, register, articulation and instrumentation can make the same pair restrained, heavy or rhythmically active.
