C# Phrygian
The C# Phrygian mode (also written Db) — C# D E F# G# A B — shown across the guitar neck.
Also written Db Phrygian. Db and C# are the same pitch, though spelling it from Db would need double accidentals (Db Ebb Fb Gb Ab Bbb Cb), which is why C# is the name in use.

C# Phrygian is the natural minor with one note changed — the b2, D. That single note is what gives the mode its sound: lean on it and the colour is obvious. Leave it out and the melody alone could pass for plain minor — then it is the chords underneath that keep the mode.
What is C# Phrygian?
C# Phrygian is the seven notes C# D E F# G# A B — the notes of A major started from its 3rd degree, C#. Same seven notes as the parent, but with C# as home, so the intervals and the sound are different.
C# Phrygian vs C# natural minor
6 of the seven notes are the same. The difference is one note, and that is the whole character of the mode:
- b2 is D in Phrygian, where C# natural minor has 2, D#.
Play C# natural minor and C# Phrygian back to back over a C#m chord and listen for D — that is the note to lean on.
Chords in C# Phrygian
Stack the mode in thirds and each degree becomes a chord. The home chord is C#m; the rest are the chords of A major, since the notes are the same — what changes is which one the music rests on. Vamp between C#m and D and the mode is unmistakable.
C# Phrygian on the guitar neck
Because C# Phrygian is A major from its 3rd note, its natural fingering is position 3 of the seven three-notes-per-string shapes of A major — the shape whose lowest note is C#. Learn that shape with C# as home — start and end on it, over a drone on C# or the vamp above — and you have the mode under your fingers. Play the same shape with A as home and you hear A major instead. The other six positions are the fingerings for the other six modes of the same key.
How to practice C# Phrygian on guitar
- Loop position 3 of A major at 60 BPM, starting and ending on C# so your ear hears C# as home rather than A.
- Hold a C#m chord (or record one) and play the shape over it. Land on D on the strong beats — that is the sound of Phrygian.
- Hear it harmonized in 3rds on the Fretboard: press Play and every note sounds with its partner while the neck lights up.
The tool draws C# Phrygian from its own root: the orange dots are on C# and the degrees count from it. The notes are its parent key's, A major; to hear Phrygian, start and end on C#.
