I've been trying to develop finger technique no my left hand and so far I hit a barrier where I cannot go any further because I'm applying too much pressure on my thumb instead of allowing the other fingers to do most of the work.
I've created a video to demonstrate my problem:
As you can see, my thumb is constantly applying pressure, and I hit a barrier of 70 bpm's where I cannot go further because of this.
As more as I try to relax the thumb and not apply pressure, somehow my body just cannot do it, although on the right hand is perfectly fine.
Any tips on how to fix this? I'm currently very frustrated... In the course of the last 4 months I've spent 60 hours just doing this exercise and still it's not as I would like it to be.
My second question poses with doing finger technique only on french grip. Shouldn't I do the majority of finger technique in german/american grip since that's the grip I'll be using in the drumkit anyway? Thing is the fulcrum completely changes if I switch to german/american grip since I'll have the fulcrum on the middle finger opposed to index finger in the french grip.
Thanks in advance!
