If you learned how to tune your guitar to itself when you first started learning the guitar, you’ll remember that the note in Fret 5 corresponds to the note of the open string on the next string down. The only exception is the 3rd string, where in order to get the same note as the 2nd string open, we need to play Fret 4. This is due to how the guitar is mostly tuned in intervals of a perfect fourth, except for the 2nd string, which is tuned a major third above the 3rd string (G to B is a major third).
