Besides choosing the tuning from the presets list, Stave'n'Tabs allows to tune each string manually.
- In the Tuning tool, scroll down to the Strings section if needed.
- Use plus button to raise up and minus button to lower down the open string's pitch by a semitone.
- Tap Done to apply a new tuning.
To listen to the open string note, press and hold the button with the string's number in the circle, e.g. ③.
