First off thanks for you excellent book. I got my copy last week and dug right in. You mention placing the right forearm one the guitar one to two inches below the elbow (I don't have the book with me right now, so I may not quote exactly). You further mention that the right hand should fall roughly midway between the soundhole and the bridge, and John Jorgenson's video, which I also ordered agrees.
My problem is that I am a tall guy with long arms. My hand ends up over the soundhole, more to the neck side. The string tension there is too soft to dig in, and now I understand why I was having some of my problems with the rest stroke technique.
So how do I adjust? To get my hand whereit should be, I have to put my armon the guitar much further from the elbow, which seems to give me less mobility. The alternative is to drop my arm farther down towards the bridge end of the guitar. I can get my hand in the right place and my elbow 1-2 inches from the guitar, but then my arm is coming in too nearly parallel with the strings, which means I can't hold my wrist in the proper position.
I am only 6'2" so we're not talking basketball player proportions here, and my arms are not freakishly long. They are just too long to easily find the textbook position. Any suggestions? BTW, Gypsy Picking is a terrific book. The most systemtized picking technique I have seen since my classical days.
I've never been a guitar player, but I've played one on stage.
