I've been playing drums for a while and there's something bothering me. I've watched a lot of "how to hold your drumsticks properly" videos for the 'matched grip' style (the one i use) to try to improve my 'matched grip'. I try to be relaxed and not apply too much force when holding my drumsticks, but when I start to play a little bit faster, they start to move in my hands. My thumb and index finger are being used to find the fulcrum point but from time to time I have to move my index finger to find the fulcrum point again.
Do I have to put more force when I'm holding my sticks? I've watched a lot of videos on YouTube but they seem all the same to me when it comes do the matched grip. I've tried the traditional grip too. Should I invest more time and effort on improving it?
