Hey, Todd – Thought I would respond, since you haven’t had a hit yet. I know nothing about music, but I do have a daughter who is 8, so I’ve been through that age phase of 4.
I’m not sure when your daughter expressed an interest in the violin, but I would recommend waiting a week or two and seeing if she is still interested. I know with my daughter, what she wanted yesterday, is long forgotten today.
Unfortunately, that’s as much help as I can give you on this topic. Good luck!
