Hey, ive been playing for a few years and am self taught, i know some say that putting your thumb over the board is bad, and im stopping that now. But when i play my left hand is fretting and i tuck my pinky in, i roll it up basically. If my description doesnt work ill post a picture but its like this. Take your left hand and make all your fingers tucked in startring at the second knuckle. so you have like little half fingers. now unfold them all but the pinky, that is how my left hand looks, i dont use my pinky to fret anything. Is this bad? Or is it only bad if it hurts? Because lately my left hand has been hurting, not just my fingers either. anyone understand me? thanks.
