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 G tuning, the open strings run D B G D G 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. The open strings in Open G form a G major chord: D-G-D-G-B-D from low to high. Find the fretted scale notes around those open strings.

Practice Tip

Treat the b5 as a passing colour and resolve it quickly for the classic bite. In Open G, compare the fretted notes with the open G, B and D strings.
