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 C tuning, the open strings run E C G C G C 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.
Blues sounds gritty, tense and expressive. Try it for turnarounds, blues-rock phrasing and greasy lead work. Open C is C-G-C-G-C-E from low to high. Its open strings form a C major chord, with C on three strings.
Treat the b5 as a passing colour and resolve it quickly for the classic bite. In Open C, use the three open C strings to check the roots when practising in C.
