In this lesson we learn how to use open strings and fretted notes that are the same pitch to get a unique effect. We start by working on the G string going between Bb and B. By alternating between open strings and fretted notes we get a sound common to a blues and rock music. You can play these examples with either your fingers or the pick. Know that you can get this effect on all of the open strings. You can also use a hammer-on to get a different effect.
