Hi! I have made a video on how to customize and raise the height of your chin rest for your violin or viola! This can help many back, shoulder, and neck problems. I thought your followers might like it! :)
For person interested in fiddle: to be honest, most fiddle music is upbeat anyway. But you can start with things like Swallowtail Jig, Drowsy Maggie, or Calliope House. For more information, if your town has a regular contradance, go! The musicians have lots of great dance tunes and are generally really excited when other musicians express interest in playing. A lot of the time they'll let you join in, no previous experience required!
