Theory & Context

Why This Shape Works

The A# Phrygian scale uses A♯, B, C♯, D♯, E♯, F♯, G♯ and the formula 1 b2 b3 4 5 b6 b7. In Open D tuning, the open strings run D A F# D A D from highest to lowest, so use this map rather than a Standard-tuning shape. Use the map to locate each A# root, then select a five-fret position to see its tablature. The chord suggestions use notes from this scale.

Overview

Phrygian sounds dark, compressed and exotic. Try it for metal riffs, Spanish-flavoured motifs and tense pedal point ideas. Open D is D-A-D-F#-A-D from low to high. Its open strings form a D major chord, which you can use alongside fretted melody notes.

Practice Tip

Hit the b2 against the root to make the Phrygian tension obvious. In Open D, find the D roots first, then follow the notes across the strings.
