I've been working a lot on my legato technique, for at least an hour a day up to 3 or so. Mostly not "'musical" stuff, just more so technical exercises and am really working on rebuilding my legato technique from the ground up. I've worked up to being able to practice legato for three hours a day in a pretty consistent way, think going to the gym. So all that said when practicing for long hours I get the occasional finger or hand pain....I'd liken it to a "good pain," I guess more of a soreness.. again akin to working out. Do you guys have any recommended treatments or remedies for this? Any harm in putting ben gay on my left hand? Any other suggestions?
