Left-handed C9 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 C9 chord
Begin on A. Use a small ring-finger barre across G, B and high e at fret 3 while the index holds D at fret 2.
- 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.
Another way to play it
Try x3233x, omitting high e. This removes the fifth but keeps root, third, flat seventh and ninth.
Fret codes are written low E to high e. An x means leave that string silent.
Practise chord changes with a metronome →C9 notes and chord formula
A dominant ninth adds a ninth to a dominant seventh chord. Try C9 moving to F and listen to the third and flat seventh resolve.
