Hey Jill, I just happened to see these posts come in last night and just watched this one first. I’m amazed at the mid range of that instrument. It has the sweetest tone anyone could ask for! Full and rich and ringing. I don’t think anyone would disagree with me on that! Great job with all the fast pace rhythms! Spot on intonation too. I am familiar with your playing standing up. I think we should always have an option to practice seated as long as we can maintain form. In this video, it looks like the bow angle to string is a little off but I would never know it listening. None of the sounds that usually give away this issue. Fantastic violin and great job on your part!
