How to play it – with fingering

Open position

String 1 (e): fret 1, ring finger (F4)
String 2 (B): fret 1, middle finger (C4)
String 3 (G): fret 1, index finger (A♭3)
String 4 (D): open (D3)
String 5 (A): not played
String 6 (E): not played

Position 3, barre at fret 3

String 1 (e): fret 4, middle finger (A♭4)
String 2 (B): fret 3, index finger (D4)
String 3 (G): fret 5, little finger (C4)
String 4 (D): fret 3, index finger (F3)
String 5 (A): fret 5, ring finger (D3)
String 6 (E): not played

For the barre, lay your index finger flat across all the marked strings at fret 3; your other fingers press the higher frets.

A shape, fret 5

String 1 (e): not played
String 2 (B): fret 6, little finger (F4)
String 3 (G): fret 5, middle finger (C4)
String 4 (D): fret 6, ring finger (A♭3)
String 5 (A): fret 5, index finger (D3)
String 6 (E): not played

The “C, A, G, E and D shapes” are the CAGED system: you slide the shape of the open C, A, G, E or D chord up the neck and your index finger (a barre) takes over the job of the nut. That way the same chord can be played in five places, anywhere on the fretboard.

Tuning: E A D G B E (low to high). String 6 is the thickest, the low E. In the diagram, × means the string is not played, and a circle means an open string.
