Theory & Context

Why This Shape Works

The G# Blues scale uses G♯, B, C♯, D, D♯, F♯ and the formula 1 b3 4 b5 5 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 G# root, then select a five-fret position to see its tablature. The chord suggestions use notes from this scale.

Overview

Blues sounds gritty, tense and expressive. Try it for turnarounds, blues-rock phrasing and greasy lead work. 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

Treat the b5 as a passing colour and resolve it quickly for the classic bite. In Open D, find the D roots first, then follow the notes across the strings.
