OK, a bit of background first. I'm a 67 year old male. A few years ago, when I hadn't been playing much, I started getting twinges of arthritis in the bottom knuckle of my left thumb (the one down by the wrist). My general philosophy of arthritis is, use it or lose it. So I stepped up my practice schedule and made a point of doing technique exercises every day.But for some reason I wasn't doing arpeggios. Now I've started doing arpeggios in 7ths, which are great for increasing extension between fingers. But I have to stop after a few minutes because of soreness. I know they'll get easier with practice, but I wonder if there's a better way.What I think I'm doing wrong is making my fingers do all the work. It's like my fingers have a death grip on the keys. I'm also to some extent using the strength of my fingers to propel my hands up and down the keyboard. This is especially hard on my thumb when I turn it under.Over the years I've seen a lot of discussion here on arms vs fingers. The consensus seems to be that it's better to let the arms do most of the work. But how do I learn how to do this after 59 years of doing it the wrong way? How do you go about teaching this technique to students? Are there exercises I could be doing? I know it will probably take me a long time to correct my bad habits, but I'd like to at least try. If nothing else it will extend my playing life before the arthritis kicks in for real.Thanks in advance.
... the truth of the matter is that one is *always* affecting the other in some way, and the largest aim is to have them -and your whole body- working harmoniously together (= smooth, efficient, non-constrained, musical motions) vs. parts of the mechanism inhibiting other parts in any way. This takes some serious exploration and investigation with specific aims. Let it be a given that any part of the mechanism should not be "static" ... if it is 'still', there is a difference between being balanced and supportive vs. being static (let's say that "static" here means resistant to any type of motion). Other than that, for this tiny snippet of a post about this subject...
But how do I learn how to do this after 59 years of doing it the wrong way?
I do not normally enter these discussions because I play little classical music and have had little orthodox technical training. However, I am also sixty-seven and much of my playing, the hundreds of hours of improvisation, is of a very physical nature. Now external conditions such as arthritis might be simply the luck of the draw, I don't know about that aspect. Speaking for myself, I am very glad I spent many years maintaining a strong finger technique. These days I hardly ever pass thumbs under and just use hand displacement. My case is somewhat unusual in that I have used a Virgil Practice Clavier to do this since I was twenty-one, but in principle the results are probably the same.Various experts have advised me, now and then, to use more arm, more weight and so on, but when I have attempted to do that I have found it leads to flaccid music and I start to feel insecure, especially with things like rapid double notes, to take an example.Therefore I caution against throwing away a dextrous finger technique unless you really have to.
I certainly don't want to abandon my finger technique, in fact I'd like to improve it so I can do ornaments in Bach quickly enough. But I'd also like to expand to do things I don't do so well now -- skips, octave passages, tremolos, Alberti bass, and so on.And I'd like to be sure I'm not putting the wrong kind of pressure on my hands. I didn't mention that I also now have bone spurs on several of my joints, which I think may be due to too much Hanon.
The best thing is to post a video. One can only speculate on what particular problems you might have to deal with, unless there is something to see. But there's nothing dangerous about moving your fingers through keys unless the arm compresses them down with force. Think how much extra pressure the arm would actually put on those fingers if it provided the energy for all those key depressions- squashing each finger into impact against the keybed.
My last teacher is the one who really got me started on the Hanon. She told me to always practice it fortissimo. And I was doing it in acciaccaturas, which is even worse.
arpeggios in sevenths/ extension?You may wish to lift your hands in an angle <> 45% from the keyboard. As the perimeter of a circle is 2piR, when you do that your fingers reach more amplitude and you did not need to do a great extension.When your hand is parallel to the keyboard, that is like the diameter of the circle and you have less amplitude. But when you lift your hand your fingers are like a circle, "ergo" <> 2 x diameter. Try it.
My English is very poor, so I was not very clear, may be.What I said is a very known technique for arpeggios in order to reach a greater amplitude.When we have our hands parallel to the keyboard we can reach one certain amplitude, for example only 11 keys. This amplitude is like the diameter of a circle.But when we lift our hand <> 45 degrees and "roll" the hand, that`s like as we make a circle instead of the diameter.As the perimeter is 2 pi R, beeing pi = 3,14 and R the half of the diameter, we have Dx3,14 of amplitude, wich is more than the diameter. So we have a gain.This is a well known technic, wich name I dont remember at this moment.
When you put your hand over a table, you may reach a certain distance between your first and your 5º finger. This distance is the diameter of a hemi-circle formed by your five fingers.But if you lift your hand from the horizontal to a vertical position, now what you have is your fingers forming a haf-circle over the table.So, when you roll your hand, you`ll reach a distance longer than the distance when your hand is parallel to the table...
Hee, hee.Geometry aside, rmb is right. Try it on the table, I just did.
Nb I never disputed the value in rotating to help cover distance. But the explanation is nonsense and accounts for no difference whatsoever.
It's not wrong, though.When your hand is flat, forearm rotation not only gains you no spread, it reduces your reach. The only way to gain distance by rotation is to move the elbow in and our pivoting around the hand. Raising the angle of the hand, and you can gain a small amount of rotation spread.
