Hi everyone, I'm new to the boards. I'm a freshman in music college right now and my main instrument is electric bass, but lately I have been starting the upright. So my issue: Holding the French Bow. My thumb is incredibly sore right now. Is this normal? Does anybody have some suggestions, links of good pictures of people holding a French bow etc? I am not sure where to put my thumb on the frog, and in relation to my other fingers. (I have an idea, but my hand doesn't agree with me). Do I just have a weak thumb that I need to bulk up? Any advice or responses whatever would be great. Thanks again.
