Make a clean Cm7 chord

Use an A-minor-seventh shape with an index barre at fret 3. Add D at fret 5 and B at fret 4.

  1. Place one finger at a time, just behind the fret wire.
  2. Pick each sounding string slowly. Adjust any finger that mutes its neighbour.
  3. Release pressure, then make the shape again. Aim for a relaxed hand.
  4. 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 x3534x if the top string makes the barre awkward. The four sounding strings contain all four chord tones.

Fret codes are written low E to high e. An x means leave that string silent.
