- Open the chromatic tuner (or play each reference tone above).
- Start from the lowest string and tune each one to B1, F♯2, B2, E3, G♯3, C♯4.
- Tune up to each pitch: if you overshoot, drop below and come back up so the string settles.
- Check every string once more — changing the tension of one string slightly pulls the others.
- Big changes from standard tuning stretch strings: give them a minute and re-tune.
