Left-handed Amaj13 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.
Fret and finger guide
Both codes read from low E to high e, regardless of the diagram view.

Make a clean Amaj13 chord
Pick only the sounding strings. Keep X-marked strings silent, place each finger just behind its fret wire, and release pressure between attempts. This practical voicing leaves out 5, 11; the full chord formula is shown separately.
- 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.

Compare the alternative voicing and choose the position that sounds clear without straining your hand.
Fret codes are written low E to high e. An x means leave that string silent.
