Contradictory? It takes tremendous physical training over a tremendous amount of time to play piano technically well. So a talented person plays there is a fantastic amount of skill and training driven by the mental and emotional content of the pianist.
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?
