If you want a step by step guide for teaching a beautiful bow hold check this book out. If you have students who need help correcting their bow hold then you need this book. It is full of helpful pictures and explanations for why there might be a problem. For example, why the thumb cannot sit in the right spot and a detailed explanation for good contact points. Also you don’t have to find a clever phrase or technique to fix it, just show your student the picture! The straightforward and practical application of a good bow hold is off the charts in this guide. I cannot recommend this book enough!
