How to tune to Open D (f♯DF♯AD)
- Open the chromatic tuner (or play each reference tone above).
- Start from the lowest string and tune each one to F♯4, D3, F♯3, A3, D4.
- 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.
