On the guitar you can get the same pitch in different parts of the guitar. In this exercise we learn how to match the pitch of open strings with fretted notes. If you push down at the 4th fret of the G string, you get the pitch B. It is the same B as the open B string. In order to play this note, it is easiest to get into second position. By alternating between an open string and fretted notes on a lower string, you can create some interesting sounds. This is especially true if you use the pick. You can practice the two sets of notes, one using the B string and another using the E string, to explore these sounds. Try coming up with your own patterns, the only rule is that you use the open string for every other note.
