Great post, Ron. Thanks, but I think Greg described the two building bit best–I believe it was in his Trumpet Chat #7–the one he posted in response to the “Am I The Only Dummy” thread.
The concept is that we’re living in our current house while we begin construction on our new house. We have to live in our current house as the new one isn’t liveable yet. We start by building the foundation, the walls, eventually the roof, etc. Eventually, we move into the new building.
Our minds are complicated and while in many ways playing trumpet is very simple, it does involve a lot of different fine motor movements that have to be coordinated delicately to have optimal effectiveness and efficiency. That takes time to learn / coordinate, but I believe Greg / WindWorks does a great job providing the important goalposts / principles to keep in mind.
