Question:

"nepatsfansc asks, "I have gotten pretty good at playing barre chords and I can get a good clean sound while playing the chord. My problem is moving between chords, whenever I do, the strings make a loud screeching sound from my fingers rubbing along them. How to I fix this? Thanks, this site is awesome- Stephen""
