A feature of many David Crosby tunes is the use of altered tunings. *Guinnevere*is an great example of how he changes the pitch of a few strings, starts messing around with chord shapes and sounds, adds a somewhat abstract melody with complex harmonies, and creates beautiful music. The tuning is EBDGAD and uses an arpeggio-style picking pattern over some fairly simple, but unusual chord shapes. He also is never concerned with playing anything exactly the same way twice, and as such recreates each song every time he plays it. We take that approach in this lesson and start with some specific patterns but look at changing and varying them on the fly.
