There may be some video, somewhere, of me playing Bach's AMB minuet in G ... I think that was my "big" attempt at something with a "rebuilt" technique.

I'd look if I could find it..
I don't think I ever "rebuilt" - I tried to, but in the end I just kept on doing what I always did, only with a greater understanding of what it was about my current skills that worked, and what didn't - it became more refined. It also kick started the process of understanding how different movements work, and what movements are even possible. So as to properly experiment and arrive at something that works and delivers the sound desired with comfort/ease. What has been more important for me as a teacher on the technical side of things has been understanding what movements cause which negative effects, and how to recognize them in a student.
Some other thoughts/experiences -
What I originally perceived on the video to be what they meant about rotation caused problems, and since they say "it can look right and still be wrong" I assume I had it wrong initially.
There is definitely "something" going on in my technique, that if I remove it causes problems
I find it hard to believe that Edna, and the rest of her faculty are all doing this meticulously in their own playing if it doesn't work well for them, or if not doing it works better, especially considering the taubman institute has effectively been around since the 70's.
Since I'm physiologically similar (we are all human), what works for them should work for me. Therefore, I have to assume that what I'm doing is probably for the most part similar to what they are doing because it works and I don't have any tension issues, or major ongoing technical difficulties.
If I had stumbled onto the motion without reference to any known pedagogy (just noticed it in my playing) I doubt I'd have thought it was sourced in the forearm as it is so very subtle. With that in mind maybe what I'm talking about isn't actually rotation at all - but given the reference to known pedagogy I'm inclined to think it is.
I think the issue is prone to disagreement because it is so incredibly subtle, and because it would ultimately not be necessary to do it on every note in order to achieve the given musical aim. But, I think that it feels better as the performer if the motion is there.

I think it would be great if marik could discuss in more detail why he thinks it shouldn't always happen, and what effects he thinks it has. Such as perhaps, to what musical end would you use it, and to what musical end would you not. As well as perhaps discuss more about what constitutes rotation over the entire musical phrase, which he said is there always. Providing that explanation may be a time consuming task though so I won't be too bothered if it doesn't happen. I'd be happy form1469to have a go too as one of mariks students
