“With the fingers falling…freely, the following intervals are produced : a whole tone between the 1st and 2nd fingers, a semitone between the 2nd and 3rd, and a whole tone between the 3rd and the 4th . . . This disposition of the fingers, which describes a perfect fourth between the 1st and 4th fingers, is the natural position of the fingers, and the basis of violin fingering.” — The Principles of Violin Fingering by I. M. Yampolsky, page 25
Adding all four fingers, for me first in Schradieck, is always a challenge for a string player. What I have found quite a few low-level violinists neglect or are unaware of is that the natural frame of the hand should always be mostly-maintained. It is easy, when unaware of this, to allow the wrist with the fingers to pivot to the right to regain a flat position, an easier position for the body, when playing lower fingers, requiring a pivot of the wrist for upper fingers, primarily the 4th. This makes acceptably-accurate intonation almost impossible because of the targets for the fingers becoming further away with more-complex hand motions. The fingers, instead, should stay directly above their natural positions on the violin and fall directly on the strings, sliding up and down the string freely of one another (later introduced in Part II of this book) for chromatics.
I spent several days playing erroneously in the lesser way, as I see many other novice and beginner violinists do on IG. Once these corrections were made, not only did my intonation improve tremendously, my tone quality became far better. I am still perfecting the accuracy of my fourth finger (and all fingers as relate to one another, to some degree), as can be expected. But it's closer and closer every day, and it doesn't hurt or strain me to play! I always say technique comes in response to a need, but a musician must learn where and how to respond to their needs. More practice won't cut it. It will only further ingrain irrational technique! Happy soul-searching!
P.S. If my squinting bothers you, hmu, and I will let you know which stand light to buy me as a gift! 😀 - 9 months ago
