How to tune to 6-string (B E A D G C)
- Open the chromatic tuner (or play each reference tone above).
- Start from the lowest string and tune each one to B0, E1, A1, D2, G2, C3.
- 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.
