I use a nylon string classical guitar so the body is fairly small. Most of
the time I hold the guitar on my right knee like you do when playing a steel string acoustic guitar but occasionally I'll hold it on my left knee in a typical classical guitar position with my foot on one of those little footstands.
I figured with the amount of players there must be some who experience this elbow or shoulder pain as well who may have discovered some secrets to getting around this ?
