One of the pitfalls of learning golf is the effort to do things "while moving." To make my point, in teaching piano in my former life, I would NOT want a pupil to "make music" with a new piece. I would ask him, "Can you play THAT ONE NOTE--JUST THAT NOTE?" The response was "Well, of course I can!" with an unspoken "do you think I'm an idiot or something?" But what the pupil is overlooking with this presumption IS THE FACT THAT THE PIECE IS MADE UP OF A SERIES OF DISCRETE, SPECIFIC THINGS. So learning the music MUST BE done with respect for what really the pupil does: like a motion picture - there IS no motion: the picture is made up of 35 cels per second! Each one correct, in perfect focus, and with unmistakable details.
So in a golf lesson if I tell a pupil AT THIS TOP OF SWING YOU NEED TO BE HERE: hands like this, club here, left arm here, "STOP AND LOOK AND ACTUALLY PUT YOUR HAND THERE!," I am giving him specific information that OF SOMETHING HE CAN DO IMMEDIATELY. There is no need to "try" AND LEAST OF ALL TO ALLOW HIM TO SWING IN HIS NORMAL PATTERN WHERE HE TAKES HIS HANDS SOMEWHERE ELSE and hence gets a conflicted message where "trying" to do one thing while doing another is impossible!
SO yes, it IS possible to "get things right" immediately; it is presumptuous to expect to flow them all perfectly smoothly at once, BUT THEY CAN BE CORRECTLY INSTALLED at the outset.
So the problem with the pianist is trying to make music before he knows the notes - and in the process fails to address those things he needs to install correctly; he may in the process fake a lot of the piece, but it would be far from well played if he didn't FOCUS ON THE RIGHT NOTE AND FINGER ONE AT A TIME and get them handled.
IT IS NOT HARD to address single details: it is fussy. And I don't mean to reduce the golf swing to positions, but to provide essentials. For example, without worrying a lot about HOW to get from address to top-of-swing, and allowing the body to work out an easy comfortable way to do it that with a little guidance builds into it the loading that is required, one can expect the golfer himself to get the club up there without microscopically managing each millimeter along his backswing arc.
A credit card over the phone can involve 28 separate details before the transaction can "take": 16 digits on the card, 4 digits for the exp date, three for the code no. on the back, and 5 for the zip code. NOT A ONE OF THE DIGITS IS HARD OR EASY; IT IS SIMPLY A DISCRETE NUMBER. So it is fussy, not hard, to get it right and effect a transaction.
This is, I think, what David intuits and states.
I promise you no successful pianist plays a concert piece nearly flawlessly without specifying the fingers and the thousands !!! of notes needed from page one to page 120 (the Brahms 2nd Piano Concerto). FLowing the notes together comes AFTER the notes are identified.
