How to Tune a Guitar to Itself Using the Fifth-Fret Method
4 of 5
Play the fourth (not the fifth!) fret of the G (3rd) string and then play the open B (2nd) string.
Note that you need to play the 4th fret this time instead of the 5th fret. Let both strings ring together. If the 2nd string seems flat or sharp, adjust the pitch accordingly.
