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

Put your index on the E string at fret 1, then add middle on the G string, ring on the C string and pinky on the A string, all at fret 2. The pinky on the outer A string is the weak link — press it firmly on its tip and keep the others arched so all four notes ring evenly.
