The biggest thing is understanding that your violin is holding your bow for you, and you don’t have to put in extra effort in your performance to hold it. That is normally what is happening–the body naturally wants to have more security on items we are holding because we would hate to drop them. But this actually causes a negative effect as you are supposed to hold the bow lighter to get a good sound! You will avoid bow bounce when you holding the bow less and letting the violin hold the bow for you. Keep your violin level to help achieve this level of balance–if your instrument is leaning downwards you will have to hold the bow tighter which you won’t want.
