Left-handed A7 diagram
Vertical: high e on the left, nut at the top. Horizontal: high e at the top, nut on the right. X = silent, O = open. Dot numbers are fingers: 1 index, 2 middle, 3 ring, 4 little. A thick line joins notes held with one finger as a barre.

Make a clean A7 chord
Start at A. Keep the G string open between your two fretted notes.
- Place one finger at a time, just behind the fret wire.
- Pick each sounding string slowly. Adjust any finger that mutes its neighbour.
- Release pressure, then make the shape again. Aim for a relaxed hand.
- Strum four beats, rest for four, then repeat. Rest if your hand becomes tired; stop if you feel pain.
More fingering ideas
Compare with A: lift the finger on G to hear the flat seventh.
Fret codes are written low E to high e. An x means leave that string silent.
