I’m officially a part-time paid musician now, and maybe close to a quarter of that time is played on fiddle. I never paid this much mind before, cause it would come up so rarely, but I’ve noticed an occurrence when playing fiddle for over an hour and a half straight. My fingers ring, giving the sensation of my bones vibrating. It’s not particularly uncomfortable, and not all that debilitating, but mentally it’s like, "Maybe it’s time to call it a day?". But who wants to call it quits when there’s a generous flow of cash falling? If the situation allowed it, I would just switch to piano but, that’s not entirely workable, or convenient. All the extra equipment and what not. I’m also not sure if it’s a sign of some other problem. It lasts so long, several hours sometimes, i’m not sure if it’s damaging. Anyone know of this phenomenon?
