Choose Tuning

You can designate an alternate tuning for certain instruments. If you select a supported instrument, you can choose one of the alternate tunings. This will change the strings to be tuned in the Tuner Widget as may also change chord diagrams if supported.

None

The default option for alternate is this which results in the standard tuning being used.
