How to Play This Chord

Position your fingers on the fretboard as shown in the diagram. The vertical lines represent the four strings, from the top G string (left) to the A string (right), and the horizontal lines are the frets. Numbers inside the dots indicate which finger to use: 1 (index), 2 (middle), 3 (ring), 4 (pinky). An X means don't play that string; an O means play it open. A bar spanning multiple strings means one finger presses across all of them at once — this is known as a barre chord.

Tips & Tricks

Lay your index across the C and E strings at fret 1 as a small barre, set the middle finger on the G string at fret 2, and the ring finger on the A string at fret 3. The half-barre is the tricky part — roll the index slightly onto its side so both inner strings ring cleanly.
