Theory & Context

Why This Shape Works

The C# Blues scale uses C♯, E, F♯, G, G♯, B 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 C# 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 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.

Practice Tip

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.
