Weird question. I have returned to bass playing after a LONG break and notice a lot of shortcomings in my playing I don't even remember having as a total beginner! Anyway, one thing that I tried today was really magical, but obviously not a good solution long term, so I'm hoping someone A. won't laugh at me and B. can suggest something that gets the same result but isn't a sock. Here's the deal: I discovered that my bow grip was really bad - again, I don't remember this being a problem before but perhaps my memory is selective. I found a way to work on that and had about 80% improvement in my bowing. But I was still frustrated by the fact that my thumb joint caves in - I have very hypermobile hands. So I tried putting a balled up sock in my hand, sort of behind the bow. Magic! All of the sudden my bowing sounded great! But of course I cannot always play while holding a sock...the very thought makes me laugh. Thoughts?
