Working on two posture changes that I have been working on to relax my playing, yet work on speed. Using a different shoulder rest, I’ve brought my left elbow closer to my body, alleviating some arthritic left shoulder pain. At the same time I am working to use my wrist more to make bowing smoother and a bit quicker. I’ll practice some in front of a large mirror to watch the position of my bow arm (wrist).
Liz Faiella has a video on relaxing the bow arm/hand. I’m going to try that method with FH’s play along of Kesh Jig, progressively faster.
