I recently asked a student to watch the Horowitz silent movie of Chopin’s Etude Op 10 #8 in F major

and then imitate his movements. This was a very revealing exercise. Horowitz ‘cocks’ his fourth finger and then has it vigorously strike into the key as his hand goes over the thumb in the descending passages. His wrist stays virtually even. It looks like there’s an undulation of hand, wrist and arm but this actually only occurs as a passive result of the vigorous finger activity.
My student however took the visible undulation to be the main element, and left his fingers, especially the all-important fourth, virtually inert. This was of course this student’s classic habit, the one of which I have been trying to cure him for years. I was struck by the degree to which his habitual pianistic self-image overrode the perception of what Horowitz was actually doing, and rendered this potentially rich learning situation barren.
When I pointed out what he had done, and guided him to eventually really do what the film shows – THAT was real learning. What a change in his sound and his sense of capability!
