Theory & Context

Why This Shape Works

The F# Phrygian Dominant scale uses F♯, G, A♯, B, C♯, D, E and the formula 1 b2 3 4 5 b6 b7. In Half Step Down tuning, the open strings run D# A# F# C# G# D# from highest to lowest, so use this map rather than a Standard-tuning shape. Use the map to locate each F# root, then select a five-fret position to see its tablature. The chord suggestions use notes from this scale.

Overview

Phrygian Dominant sounds bright inside a dark frame, with a strong Middle Eastern pull. Try it for metal leads, flamenco-inspired riffs and dramatic dominant vamps. Half Step Down lowers every string by one semitone. Chord shapes keep their familiar string relationships, but the sounding notes change.

Practice Tip

Emphasize the jump from b2 to 3 to define the mode instantly. In Half Step Down, remember that a familiar shape now sounds one semitone lower.
