Chords & scales

Shapes for guitar, ukulele and piano, circle of fifths.

How it works

Shapes are worked out for each chord and tuning: the first ones are the easiest.
The number by a diagram is the fret it starts at; X = muted string, O = open string.
Each step clockwise round the circle adds a sharp; neighbouring keys share almost every note.
