Exercises for string crossing
Okay, I've been at this almost 9 months now - almost enough time to hatch a kid. My left hand is making steady progress (albeit all in first position) and intonation is decent. And as long as I stay on one string, I can draw the bow reasonably straight with even pressure. But when I have to start crossing strings, I'm afraid the neighbors will phone up animal control because they think I'm vivisecting felines.
At least I can at least figure out why this is. My wee little brain is still having trouble coordinating the movements between my two hands. When I practice R hand alone on open strings, I do okay. But as soon as I divert more than 7% of my attention away to what my L hand is doing, I tend to reach for the next string with my wrist rather than move my elbow to get over to that other string, which causes all sorts of Bad Things to happen.
So I'm wondering if anyone has any suggestions for exercises that would allow me to practice string crossings with some but not too much activity in my L hand.
I think practicing on open strings is a good start, then you can start playing with your first finger down and so on. There is so much to consider while playing, but it will get easier.
What does your teacher suggest? Ask about it if need be. Try to keep your movements as small and precise if possible. I'd start with open strings, then, add one finger, then two, and keep increasing the complexity of the exercise as your confidence increases.
Scales. Scales. Scales. 4/4 first one note on one bow, then two, then 4, then 8. Make stops between notes, then bring them together in legato. Then 3/4 (count 1,2,3), first with one note on one bow, then 3 etc. In 3/4 the last note is longer. Then arpeggios in the same way. Start with a scale you are familiar with. Then move to the others. Everything is in two variants: starting bow down, and starting bow up.
