C♯ blues scale — guitar notes & shapes

The C♯ blues scale is C♯, E, F♯, G, G♯, B. The blues scale is the minor pentatonic plus one passing note, the flat 5th (“blue note”). Use it as a quick, gritty chromatic step between the 4th and the 5th.

On the fretboard

Red = root (C♯). High e string on top, like tab. Numbers show the scale degree. Shaded area: position 1 (frets 9–12).
