I still suffer from the “death grip” on the neck and when I catch myself I try to relax but it can be hard to do. I was never given any advice on how to relax either so it has been a trial and error thing with me. I do think that as I play more and get better I am able to relax my hand more. And of course playing happy fiddle music helps. I will be interested in what other people have to say about this.
