Having trouble with changing chords. Changing from a barr chord to an open chord or vice versa. Play classical but when it comes to the chords I just seem to be having trouble. Am I expecting too much or do I just need to practice, practice, and practice. Can anyone give me an idea of how to practice my chord changes. I'm trying to play with my church band and I feel frustrated that I am having so much trouble with chords and chord changes.
