Years of toe and heel tapping will take its toll, friends. As a young man, I pounded heavily with my right foot until I noticed that my leg and hip were always sore after a session. By pure persistance, I managed to change to my left heel, but that only messed up my left leg too. For years I tried to let the rhythm flow through subtle big toe movements. That works on slow stuff, but when my (French Canadian)fiddler pal and I really get down to it at a gig, we always end up stomping and dancing while we play. Sometimes it takes nearly a week to recover. Get that tapping under control right from the beginning!
