You might wonder whether touch so sensitive as what I have been describing is accessible only to great artists like Rubinstein.

I could tell when I heard a nine-year-old play that the sound she loved best was the B-major triad. I hear in the touch of another child that the action on her piano at home is much stiffer than mine. Last week an older woman's touch revealed that her piano at home sounded better than it had in months.

Could it be that this intimacy is what we all crave?

Is it possible that Killer Scales drill it out of our ears and fingers?
