I have been self-learning for about a year. I am now starting to have doubt that I hold my bow properly. I hope you can give me some advice.
My particular question is: Where to put my thumb? Until now I have been putting my thumb in the frog curve. I recently read that the thumb should touch the beginning of the frog and the bow stick. What do you think? Should I change my way of holding (it will take some time to adjust) or is it not a big deal and I can keep on playing like before (without fearing of staying behind in my bowing technique)?
