You've moved the goalpost.
Unless I'm wrong, TMe was merely noting that DISCUSSION around hammer technique still abounds, despite the fact that hammering seems like such a straightforward thing. I see no suggestion on his part that construction workers "learn" how to hammer on their first day.
The point is, whether you're talking about how to swing a hammer or how to throw a drumstick, there are techniques and subtleties that people derive real value from discussing.
You don't just get to just dispense with 200+ years of time-tested drumming orthodoxy because you're annoyed by it.
I'm not seeing who is annoyed
at any rate ... the discussion is about all hands being different and using what is natural without being told what is "correct"
there is no "correct" across the board
you like a thumb and index fulcrum ... wonderful ... I wish you years of success with it
in my opinion no teacher should ever tell you that there is a "correct" and "incorrect" way to hold and motivate a stick ... a proper teacher presents options that relate themselves to natural movement
a lot of times so much time is wasted working so hard on what a student feels is "correct" because his teacher says so and it feels so uncomfortable and unnatural but they grind it for 4 months and force it to feel good ... when they could have explored options and been finished with that process in probably one day
I personally know multiple teachers who insist on teaching index/thumb fulcrum and preach this first knuckle stuff ... but then you watch them play and they themselves are not using anything of the sort
it is like they are programmed by that 200+ years you speak of to teach that way when they themselves don't even use it
almost every drum teacher I know seems so afraid to go against what seems like some holy tradition ... like lightening is going to strike them if they do not live by what other teachers have said
teachers waste too much time with minutia that is not very important in the grand scheme
I have a number of past students who I handed their first pair of sticks who ended up going to some of the most prestigious music schools and conservatories in the world ... a couple on scholarship ... many who now work full time as players in the industry.
this is what I dedicate a large portion of my life to ... the words "this is how you hold a stick" have never been uttered in my studio
if a teachers is forcing a student to use a hand position that they have to constantly concentrate on keeping or that feels unnatural they are wasting valuable time that could be dedicated to furthering the advancement of the student.
you guys be well ... this discussion has grown long in the tooth for me
