So I've been playing flat fingered my whole life. Recently In talking with a jazz bassist in town I was told that playing should be with the tip of my fingers, thump planed on the back of the neck and not using much pressure when fretting. I've spent a great deal of time focusing on this and working on the efficiency of my playing by not moving my hand as much (i.e. trying to fret in one area when running blues scales instead of moving down the neck). However, I'm finding that when I use the tip of my ring finger and pinky, pain shoots through them near the first knuckle. I even use one of those finger strength trainers thinking that I've spent so much time playing wrong that my fingers are just not used to it. But the pain is getting in the way of my playing. Will this pain go away after I get used to playing this way? Is there anything I can do to minimize this pain?
