I just started playing the violin a few days ago. I looked at a few videos here an there before and after my first violin lesson, and of course, the spider exercises came up a few times (including during the lesson).
After practicing it on my own a few times, I noticed I can't seem to slide my thumb down the bow (when going against gravity) if it touches the bow too much.
From what I understand, when holding the bow, only the very tip of the thumb should be touching the bow. Unless I do the same thing in the spider exercises, the friction won't let me slide down my thumb. If the thumb slides just a tiny bit inwards, the friction is too strong.
Didn't really see a reference to this point anywhere. Should I be able to do it even if it's not just the very tip of the thumb touching? Or do I just need to make sure my thumb doesn't slide a little bit inwards?
