How to tune to Double C (gCGCD)

  1. Open the chromatic tuner (or play each reference tone above).
  2. Start from the lowest string and tune each one to G4, C3, G3, C4, D4.
  3. Tune up to each pitch: if you overshoot, drop below and come back up so the string settles.
  4. Check every string once more — changing the tension of one string slightly pulls the others.
