bowing with the fingers
my current violin teacher hasn't adequately explained a lot of bowing techniques to me, leaving me very confused about a few things. in fact, I'm not even sure bowing with the fingers is the correct term for it. my teacher says I'm doing these things correctly, but I still have lots of questions
1. is colle bowing when you bow with just moving your fingers/wrist?
2. is it possible to do tremolo with just moving your fingers or wrist?
3. what's the difference between spicatto and sautille and do those both require bowing with the fingers?
Actually Vivien's new video shows you just how to do this. I suggest you watch that and try what she shows, it's very clear.
What Scott Cole says!
My teacher tells me to practice this very thing and it is quite literally the hardest thing I've ever done relating to playing an instrument.
regarding question 2, tremelo with the fingers only would be really contrived. allowing the wrist to move as well, definitely yes, like Scott already said.

For those of us on the eastern side of The Pond, the equivalent climb would be Croagh Patrick (St Patrick's Mount) in Co. Mayo, Ireland. The hard climb here is actually a very steep and often treacherous walk, sometimes on hands and knees for some; and the easy "climb" is an easy low gradient track a few miles long on the other side of the mount. I'm not going to say which I've done!
The basic hand shape often has a curved pinky (on top of the stick), and a curved thumb.
