I was playing my cello, and when I played a note — not too hard, around f or mf — the bow hair suddenly became loose. Now, when I tighten the bow, the hair stays soft and can’t be tightened any more. I screwed out the adjuster screw, and nothing seems broken. What could have happened?

will ask my teacher and luthier later, but I just wanted an answer now. The bow is on loan, and I was thinking about buying it, so I’m kind of stressed.

If you want pictures of specifik things just ask

I am a 15-year-old male, and I first noticed that I might have scoliosis just now. I realized that my right shoulder is higher than my left, and I also have a mild case of pectus carinatum (pigeon chest), which developed during puberty. When I saw that about 15% of people with pectus carinatum also have scoliosis, I started putting the pieces together. How should I move forward, and will I need treatment? Do you have any advice?
