So it is written in that link Goose posted:
"The purpose of this article is to outline a time-efficient, simple, and certain way of developing a quality finger technique."
The first excercise is to hold a chord of G# B D F G# in BH and hold down the notes but keep repeating the 5ths. He doesn't mention at all how you are supposed to repeat these notes, he just says repeat it. This offers 0 guidance to someone who wants to start out. one would have to add description as to how the 5th fingers should fall. It would be hepful to add that you should fall with the entire left side of the Lh (palm down) when the LH 5th strikes its notes, similarly the RH 5th must fall with the entire RH side of the hand (palm down).
However i think this excerises offers little, but it is proclaimed it will help in 3 ways
-to strengthen the fifth finger in both its downward (sounding) and upward (articulation) aspects.
- to render its action (the 5ths) independent of the other fingers, and independent of movement of the arm or wrist; and,
- to develop orientation, sensitivity and control in the fifth finger.
The first one yes it does, but so does 100 other excersises.
The second one is blasphemous. The action of the 5ths independent of the movement of the wrist is just stupid because that then restricts the 5th finger to move just by itself which is a maximum of discomfort. The finger must drop with the entire side of the hand, not just use its own weight, this is the control of efficient playing, not finger playing which will simply kill your hands in the end.
The third one is pushing it and just being over confident in the value of the excersise expressed. Orientation is not there since we are not moving anywhere and maintain a stagnant position, sensitivity isnt there because there is no music to attach a sensitive expression to, and again control is highlighting orientation, which isnt there because we are simply controlling a stagnant position which offers not a great deal.
the rest of the article encourages that we do the same process of repeating the notes on every single finger. Again the same comments apply to each finger as with the 5th.
I would have to say the article is a waste of space, simply because what was written could be written in about 2 sentences, i.e:
"Hold this 5note chord in both hands, now simply repeat each finger in each hand until you are exhausted. Trust me, this will make your playing good enough for Rachmaninov."
make your own decision if this is good advice or not!
