Is learning to play the piano well the result of a very specific process? I guess I can see that. I might be confused by a lack of clear division between training and application of This Stuff when people talk about it.
Piano is an interesting analogy. If you had two warriors, and one came from a camp where learning how to fight was about as difficult as learning to play piano, and another came from a camp where learning how to fight was about as difficult as learning to play football, and each had about one year of training...which do you think would survive a fight?
You must be kidding... I both trained formally in classical piano most of my young life. And I enjoyed football. So? And what the hell are you talking about?
How about the 6'4 250 pound lean, athletic kid with a bad atittude who loves piano... That's who'd win the fight.
Geez... I must be missing something... We are intentional creatures. We do not move solely as "machines" in any non-trivial task. There is an entire system of conscious and subconscious control involved in most every non-trivial task involving movement. The skills in any task involve developing physical attributes, physical skills, but also mental skills even at the tiniest levels.
Seriously, I must be missing your point here.
