How to Play This Chord
Position your fingers on the fretboard as shown in the diagram. The vertical lines represent the strings, from low E (left) to high E (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
Open A7 removes one finger from the A major shape, leaving the G string open. This simple change introduces the dominant 7th sound. It's a critical chord for blues, folk, and country music. The open voicing has a bright, jangly quality that's perfect for acoustic playing.
