C# Phrygian (Db Phrygian) on Guitar

Phrygian is a minor scale with the note directly above home pushed down a semitone — instant darkness. The notes of C# Phrygian are C#, D, E, F#, G#, A, B. Its characteristic note is D — the flat 2nd — the one note that gives this minor-type scale its colour.

That flat 2nd is the sound of flamenco, of Andalusian cadences, and of half the metal riffs ever written. It sits a single fret above the root, so the tension is always one finger away.
