Tuning a Mandolin to Itself
If you do not have another instrument to tune to, you can tune the mandolin to itself by using the following method. However, this usually requires many months of practice. You will probably need your music teacher or musician friend to help you tune when you are learning.

- Place a left finger on the 4th string (thickest string) at the seventh fret, and play the string.
- Play the open 3rd string (a D note). If this note sounds the same as the note you played on the 4th string at the seventh fret, the D string is in tune.
- If the open D string sounds higher, it means that it is sharp. Turn the tuning key slowly in a clockwise direction. This will lower the pitch of the string. Play the two strings again and compare the notes. Keep doing this until the open D string sounds the same as the G string at the seventh fret.
- If the open D string sounds lower, it means that it is flat. Turn the tuning key slowly in a counter-clockwise direction. This will raise the pitch of the string. Play the two strings again and compare the notes. Keep doing this until the open D string sounds the same as the G string at the seventh fret.
- Tune the open 2nd string (an A note), to the note on the seventh fret of the 3rd string, using the same method as before.
- Tune the 1st string using the same method.
