Adding fingers on the violin is altogether far-trickier and involving more fine motor skills than most methods and teachers recognize. not only are you dealing with the precise location of each individual finger, you are training your hand as to the relationships between each finger and in consistent posture.
tuning is the primary concern. i have been spending no small amount of time at a keyboard making absolute certain i am training my hand and ear to find the exact centers of pitch so i maintain a stable learning process for each finger as added.
i probably spend north of 3 hours a day practicing, which to some may seem quite impossible with such simple-seeming exercises. but mastering other disciplines has embedded in me how crucial it is to get the coordinations right from the very beginning.
the second set of second finger exercises is almost finished. i hope to post another video from this set on monday, after the medium-height bridge arrives and is installed. after that, it's on to a bit-more-demanding second finger in first position exercises! i will be learning second finger in the third and fifth positions next, and after that i will be adding chromatics to the fingers and positions thus-far.
