A Phrygian is the most exotic and immediately recognisable mode in Western music. The moment you play its first two notes the sound is unmistakable — dark, tense, Spanish, ancient. It is the scale of flamenco guitar, Spanish classical music, metal riffs and film scores that need a sense of mystery and danger. One note separates it from the natural minor and that one note changes everything.

What is A Phrygian

A Phrygian is the natural minor scale with one note lowered — the 2nd degree. A natural minor has B natural as its 2nd. A Phrygian has Bb. That single change creates the characteristic half step between the root and the 2nd degree that gives the mode its dark exotic quality. It is the third mode of the F major scale containing all the same notes as F major but starting and resolving on A.

The Notes

A — Bb — C — D — E — F — G — A

Compare to A natural minor: A B C D E F G A

One note different. Bb instead of B natural. That half step from A to Bb at the very beginning of the scale is what gives Phrygian its instantly recognisable tension.

Open Position

The open position looks almost identical to A natural minor open position — the only difference is the Bb note which sits one fret higher than B natural throughout the position.

A Phrygian notes: A Bb C D E F G

Low E: 0=E  1=F  3=G
A string: 0=A(R)  1=Bb  3=C
D string: 0=D  2=E  3=F
G string: 0=G  2=A(R)
B string: 0=B(no — not in scale)
          1=C  3=D
e string: 0=E  1=F  3=G

Open Position (R = Root note A)

e |--0--1--3--|    E   F   G
B |--1--3-----|    C   D
G |--0--2-----|    G   A(R)
D |--0--2--3--|    D   E   F
A |--0--1--3--|    A(R) Bb  C
E |--0--1--3--|    E   F   G

Fingers: Open=0  Index=1  Middle=2  Ring=3

The Bb appears at fret 1 on the A string — right next to the open A root. That half step interval between open A and fret 1 Bb is the entire Phrygian character under your fingers. Play from low E to high e and back down with alternate picking starting at 60 BPM.

5th Position

The 5th position looks almost identical to A natural minor 5th position — the only difference is Bb at fret 6 on the low E, A and high e strings instead of B natural at fret 7.

A Phrygian notes: A Bb C D E F G

Low E: 5=A(R)  6=Bb  8=C
A string: 5=D  6=Eb? -- no. A string fret 5=D fret 6=Eb
         wait A Phrygian has no Eb.
         A string: 5=D  7=E  8=F
G string: 5=C  7=D
B string: 5=E  6=F  8=G
e string: 5=A(R)  6=Bb  8=C

A string fret 5=D fret 6=Eb -- Eb not in A Phrygian
A string Phrygian notes: 5=D  7=E  8=F -- yes these are correct

D string: 5=G  7=A(R)
D string Phrygian: 5=G  7=A -- yes correct

5th Position (R = Root note A)

e |--5--6--8--|    A(R)  Bb  C
B |--5--6--8--|    E     F   G
G |--5--7-----|    C     D
D |--5--7-----|    G     A(R)
A |--5--7--8--|    D     E   F
E |--5--6--8--|    A(R)  Bb  C

Fingers: Index=5  Middle=6  Ring=7  Pinky=8

The Bb appears at fret 6 on the low E and high e strings — one fret above the root A at fret 5. That half step interval right at the start of the scale is the Phrygian sound announcing itself. Play from low E to high e and back down with alternate picking starting at 60 BPM.

Natural Minor vs Phrygian — Side by Side

A Natural Minor 5th position:
e |--5--7--8--|
B |--5--6--8--|
G |--5--7-----|
D |--5--7-----|
A |--5--7--8--|
E |--5--7--8--|

A Phrygian 5th position:
e |--5--6--8--|   <- Bb at fret 6 instead of B at fret 7
B |--5--6--8--|
G |--5--7-----|
D |--5--7-----|
A |--5--7--8--|
E |--5--6--8--|   <- Bb at fret 6 instead of B at fret 7

Two strings change. Everything else identical.

Practice Checklist

Work through every item. Master each one before moving to the next.

• ☐ Natural minor vs Phrygian comparison — play A natural minor 5th position then A Phrygian 5th position, hear the Bb on the low E and high e strings (fret 6 instead of fret 7). Repeat 10 times. Target: 3 minutes
• ☐ Flat 2nd isolation — play A (fret 5 low E) then Bb (fret 6 low E) repeatedly. That half step interval is the entire Phrygian character. Repeat 20 times. Target: 3 minutes
• ☐ Open position up and down — low E to high e and back, alternate picking, metronome 60 BPM, 10 clean repetitions. Target: 5 minutes
• ☐ 5th position up and down — low E to high e and back, alternate picking, metronome 60 BPM, 10 clean repetitions. Target: 5 minutes
• ☐ Connect open to 5th position — play up through open position then continue into 5th position without stopping, come back down through both. Target: 5 minutes
• ☐ Andalusian cadence — loop Am G F E, improvise with A Phrygian over the top, emphasise the Bb note to announce the mode. Target: 8 minutes
• ☐ Am Bb vamp — loop Am and Bb alternating, improvise with A Phrygian, feel the exotic tension. Target: 8 minutes
• ☐ Active listening — listen to White Rabbit by Jefferson Airplane, identify the Phrygian quality, feel the exotic tension building throughout the song. Target: 4 minutes
