So i haven't been playing very long and I've been mostly teaching myself. My only lesson, however, was from a great guitar player who has been playing forever and produces music. One piece of advice that he gave me that may help is just to keep practicing switching between chords. He told me to do it whenever I'm bored or watching TV. Just sit there and go through all the chords that I know. Another thing that he said is to learn to play a difficult song all the way through slowly making sure I can switch chords in time and right before being about to do it at the right tempo.
I hope that made sense and helps. <img src="images/smiley_icons/icon_smile.gif" border=0 alt="Smile">
