I've been listening to (and watching videos by) Eric Johnson a lot lately. IMO, his uncanny left hand /right hand sync is one of the main things that separates him from other pros and probably one of the reasons so many - even non musicians - comment on his sound, that it's so smooth and fluid. Syncing your hands perfectly should really be the basis of any player's toolbox but somehow it's often overlooked. There is a "good enough" mentality I think; we can get away with some bad sync so we do and I am one of the main offenders, I'm afraid. Which leads up to my simple questions: how do work on improving left/right coordination in your playing? And if already in perfect sync: how did you get there?
