Yeah, but does it work?
How do you tap chords???
Hrm. Do you play chords with finger movement I sure hope not ...
If my memory serves, the most conspicuous chords in the Goldbergs (Variation #16) Gould rolled, but in any cases, there are the chords in variation #29 that he definitely didn't roll. If he finger-tapped them at all, he probably pushed his finger tips forward rather than just "down."Personally I don't think this practice technique is all that interesting. What's interesting is that he obviously developed himself as an artist, by sitting for hours at a time, trying to find the maximum result for the minimum effort. It happened that he organized his physical approach through this method of finger-tapping, but I would counter that his achivement was rather a success of his insanely obsessive mentality, rather than the method itself.It's my point of view, though, that exercises in themselves are only useful insomuch as you put your concentration into it. In that sense, exercises are not particularly beneficial, because you can also achieve leaps in strides in your technique from condensed concentration on passages from the repertoire; therefore, don't take a lot of time playing exercises, unless you are obsessed with a specific thing.Walter Ramsey
Are you asking if Glenn Gould's piano technique was good enough?
I seem to understand what he is saying something like this: We use way too many muscles and way too much effort when we play and this creates tension and negates economy of movement. If you tap your finger down with the other hand, you will experience what needs to move, and can physically compare the difference between the few muscles/tendons being used and the many you usually use. Theoretically that would educate the body in a kind of biofeedback way. I haven't tried it, but I can picture it.
