I know I need to see a teacher again (I haven't for the past 4 years, but I was with a teacher for about 6 years before that). I wish it was that easy! There are NO teachers that I know of here where I am, State College, PA and if any of you guys know of any please let me know.
I tried practicing today paying more attention to relaxing my jaw and hand. I followed some of the suggestion from viewtopic.php?f=71&t=33040
The result is that my hand was more relaxed, especially while playing simple slow exercises, but I think there's something wrong with my posture, in the sense that I feel like there's some kind of imbalance that leads me to make too much effort on the right side of my body. At some point the muscles right above my right hip got a little aching and I had to spend some time trying to adjust my position to be more balanced. This was kinda difficult as it would change the position of the guitar with respect to my arms and all kind of small adjustment in the position of my right hand with respect to the strings.
Well, that's my experience so long. I'll keep posting updates in the hope I find a guitar teacher soon (or finally decide to take a 4 hour round trip to Pittsburgh to see a teacher there).
