twocats keystring so when I practice this etude it's not a full circle (only half circle, going back and forth with my wrists higher up), it is impossible with a lower wrist. It is also very good in the right hand to practice travel to those very high notes.
Thank you for sharing your experience. I was thinking how best to answer this. So, writing about any kind of motion in the playing of a piece risks becoming formulaic, turning the student into a self-programmed robot that says "I must do circles." A single shape like a circle is also simplistic, because there is a host of subtle and varying motions and paths that a pianist does as they play. Then if only circles, along which plane are we talking about? Another important thing is that things pianists do can be subtle and miniscule, but the difference between those micro-movements, versus a rigidly held position that might look the same, makes every difference in mobility and ease. For example, you might have micro-movements or in other words, you're not holding anything rigidly. Those were all thoughts.
My situation was that I tended to move along a narrow plane. First there was little "higher and lower" as my hands moved. There was also little "in and out" in the sense of in toward the fall out, out toward the edge. The circle is a first means of getting out of that flat plane from the very act of going higher and lower. First it was artificial, and then I started to get a feel for it. This also goes with the actual shape of our hands, the length of our fingers.
The etude came to my attention after I had fixed a first major problem, and I saw Woroniki demonstrate circles and this etude was part of one of those demonstrations. (He also showed other movements for this etude.) I knew it was something I didn't have. I was "locked up" in the arms, and there are complicated reasons why that was so. In the course of working on and with this, I am able to play a measure of the etude at a 60% tempo, without anything locking up or getting tense, and making the melody note louder, the other notes softer. A whole bunch of things have fixed themselves by making that (and a few other things) the central focus. But I don't literally "do circles" in a programmed way.
This has helped me for where I find myself, and the ongoing remediation and relearning needed because of my beginnings.
I hope this makes some sense. ๐
