Hey there VeeTG, great post! How do we indeed… It is just the way it is, efficient players, hard working players. People sharing what they think they are doing and perpetuating the “it’s hard work playing brass” myth.
If you are at a point in your playing where things are not working for you, you are in the right place.
I does not really matter why or how this has all unfolded over the decades, the fact is that it has and my endeavour is to help sort it out.
Ramble away any time! Enjoy the course.
