Phrygian is a minor mode with a flat 2nd. The half-step b2 – 1 creates its most recognizable melodic gesture, while the minor tonic beside the major bII chord produces the characteristic i – bII movement. With no leading tone, Phrygian is usually anchored by a tonic pedal or repeated riff. It appears in metal, flamenco-influenced music, film scoring and modal jazz.

Phrygian is a minor mode with a lowered 2nd degree. It differs from natural minor, or Aeolian, by one note: it uses the minor 2nd b2 instead of the major 2nd 2. The minor 3rd establishes the mode’s minor quality, while the semitone between b2 and the tonic creates its defining sound. Degree b2 also produces the major bII chord, which is often used to move toward the minor tonic. The mode has no leading tone: b7 lies a whole tone below 1.

1 — tonic: the modal center and the root of the minor i and i7 chords.

b2—minor 2nd / minor 9th: the defining degree of the mode. It lies a semitone above the tonic, serves as the root of the major bII chord, and often resolves downward to 1.

b3—minor 3rd: establishes the mode’s minor quality, belongs to i and i7, and serves as the root of the major bIII chord.

4 — perfect 4th / 11th: belongs to the tonic minor environment and serves as the root of the minor iv chord.

5 — perfect 5th: a stable tone of the tonic minor chord. The chord built on the 5th degree is diminished, v°, rather than an ordinary minor or major V.

b6—minor 6th / flat 13th: serves as the root of the major bVI chord and distinguishes Phrygian from Dorian b2, which has a natural 6.

b7—minor 7th: belongs to i7, serves as the root of the minor bvii chord, and does not function as a conventional leading tone.

Harmonizing the scale in triads produces:

i—minor; bII — major; bIII — major; iv — minor; v° — diminished; bVI — major; bvii — minor.

The diatonic seventh chords are i7, bIImaj7, bIII7, iv7, vø7, bVImaj7, and bvii7.

The mode’s principal harmonic marker is the combination of a minor tonic with the major bII chord. The motion bII–i emphasizes the resolution of the defining b2 downward to the tonic. The chord on the 5th degree is diminished, so diatonic Phrygian has no ordinary V or V7 dominant. The bIII7 chord has the structure of a dominant seventh chord, but this does not mean that it has dominant function relative to the Phrygian tonic.

In E Phrygian, the triads are Em F G Am Bdim C Dm; the seventh chords are Em7 Fmaj7 G7 Am7 Bm7b5 Cmaj7 Dm7.

Phrygian is used in modal music with a minor center when the minor 2nd above the tonic needs to be emphasized. A typical harmonic foundation is a sustained tonic bass or i chord alternating with bII. Repeating the tonic in the bass helps preserve the Phrygian center and prevents the same pitch collection from being heard primarily as its relative major key.

In jazz chord-scale theory, Phrygian corresponds to the iii7 chord of a major key. For example, E Phrygian contains the notes of C major and may be used over Em7 when that chord functions as iii7 in C major. Degree b2 is a minor 9th above the chord root, so it is normally treated as directed tension rather than a neutral stable tone.

The mode is also used in modal jazz, rock, and metal, especially over minor pedal points, riffs, and i–bII motion. It should not automatically be used over every minor chord: when the harmony calls for a natural 2, the Phrygian b2 will conflict with it.

Phrygian is the third mode of the major scale. Its relative parent major scale begins on degree b6 relative to the Phrygian tonic. For example, E Phrygian and C major contain the same notes, C D E F G A B, but E is the center in E Phrygian.

Its closest parallel mode is Aeolian, 1 2 b3 4 5 b6 b7. It differs only in the 2nd degree: Phrygian uses b2. Locrian has the formula 1 b2 b3 4 b5 b6 b7 and differs through its lowered 5th. Dorian b2 has the formula 1 b2 b3 4 5 6 b7 and differs through its natural 6th. Phrygian Dominant has the formula 1 b2 3 4 5 b6 b7 and uses a major 3rd instead of b3.

Over the minor tonic, begin with the chord tones 1 b3 5 b7. To make the line sound specifically Phrygian, regularly expose b2 and its semitone relationship with the tonic through motions such as b2–1, 1–b2–1, b3–b2–1, and 1–b2–b3. Without b2, the melody can easily sound like ordinary natural minor.

Degree b2 forms a minor 9th against the tonic. When the chord root is sustained in the bass or accompaniment, holding b2 creates strong friction. It can be used as a brief tension resolving to 1, as a passing tone between 1 and b3, or as a sustained color only when the harmony specifically supports a b9.

Over i–bII motion, follow the notes of each chord. In E Phrygian, for example, F is b2 over Em but becomes the root of the F chord. When the harmony returns to Em, the motion F–E emphasizes the Phrygian resolution.

When Phrygian is used over iii7 within a major key, follow the current minor chord and the voice leading of the larger progression. Place 1, b3, 5, and b7 on structural beats, while treating b2 deliberately as tension.

Phrygian is a minor mode with a lowered 2nd degree. Its foundation is a minor tonic, i or i7, while its defining sound is the semitone motion between b2 and 1. The bII chord brings the same color into the harmony, especially through bII–i motion. Unlike natural minor, Phrygian uses b2; unlike Phrygian Dominant, it retains the minor 3rd b3.
