hello Choo, I hadn't realised you were running such a lively thread here - much busier than the 'other place'.
So, what with the excellent advice you're getting from Birba and AJ, perhaps I could tag along here also?
regards, dt
Hi Dire_tonic..
I took a look around the "other place" - saw this..
"I’m not so sure about the rotation idea and although I humbly acknowledge AJs authority on the subject I’m not convinced it’s for me. For example, I notice when I play bar 8 which has a fair quota of left/right-ing, that the faster I play the more my wrist rotates so, bearing in mind I was never taught to rotate, this suggests to me that it's more a natural consequence than a technical device. But it may turn out to be useful for you, I don’t know. In any case, I suspect (I could be wrong) you'll be unable to start working on increasing tempo in any section until it’s under complete control of muscle memory. If that includes attention to rotation as well, then you have extra work to undertake. But I don’t rule out its possible long-term benefit to your technique – I’m not qualified to know."
You're point is pretty valuable - about the bar 8 section where a sense of rotation is quite intuitive i think.
It can be valuable for some people because there are situations where people have been taught specifically not to rotate. This situation is fairly unusual i guess. My video is not directly applicable to any one persons situation, rather just an analysis of those bars, its a lesson on a concept more than it was directly applicable. If the rotation is incorrect at a point it can really disrupt the passage, so its important. Try the LRLRLR in bar 8, but do something like LLRRLLRR - it will be plainly obviously that its important - this section is not one likely to cause a problem for most people though. By contrast, going R after the thumb when you come down from the top of the phrase is likely to cause a problem because of the notes going left, its easy to assume that you arm must continue to go left. - Or perhaps, attempt the phrase without letting your forearm turn, it will cause your fingers to take on a much bigger workload and you will feel the tension.
With all that in mind - the best way to tackle this on an individual basis is to take a look at a whole phrase. If there's a problem with a part of the phrase you might check the rotational is going the right way, maybe just 2-3 notes don't work quite right and thats all you need to deal with.
I actually think better understanding of rotation is important for choo as a means to resolving tension in her hand overall, to allow her to speed up comfortably. This phrase seemed like a good way to illustrate some beginning information about it. I think that dwelling too much on it is not a great idea - rather the understanding/execution can be discussed and worked on over time and gradually implemented into the technique.
I can't impress enough that its just a discussion on one small aspect of a big picture, but in saying that sometimes its hard to maintain that careful distant perspective on the situation when you're dealing with a great mass of information that can be a little overwhelming.
