Hi everybody, I feel a little background for my question will lead to more productive responses.
I am a guitarist but not a classically trained guitarist. I play other styles (mostly jazz) and have had a very consistent private teaching practice for the past ten years or so.
I have several classical guitar method books: solo guitar playing book 1 and 2 by Frederick Noad, and Pumping Nylon. I have a few other random books of classical guitar music.
I also have had on and off problems with extreme pain in my shoulders, arms, and hands for about eight years, for which I've received various treatments.
In the process of managing my symptoms I completely revamped my technique (I used to play in the standard 'rock n roll' way) and now try to play most things with what I would call 'classical guitar position' for the hands and the body, with some modifications. My technique is a combination of what I learned from the books mentioned, doctors and physical therapists I have seen, some things I have learned from lurking this forum, as well as some help from guitarists I have studied with (not classical guitar teachers, though.) I also have been studying Alexander Technique for about five months (still trying to get out of that chair!) and am trying to apply those principles to the guitar.
That introduction out of the way, I am interested in material for 'guitar technique' mainly for the purposes of being able to better instruct my students on how to approach their instrument with efficiency, safety, and a minimum of bodily tension. These are topics I already cover in my lessons, relaying what I have learned from my experiences, but I feel a more in depth look would A. help me instruct them better and B. probably help my in my own playing, both in relieving excess tension and maybe even improving my abilities on the instrument.
Jamie Andreas's "Guitar Principles" material looks very good and extremely thorough, the Aaron Shearer method books were also recommended to me, as well as William Kanengiser video material. Which would you recommend?
Any recommendations for the best resources for this specific purpose would be very interested. Any advice or thoughts about the project would also be appreciated.
Thanks in advance!
