Check out the “Let it Snow” Xmas 2020 Group youtube project!”
I read an article about the 10,000 Note Check Up
I'm sure some of the members here who have owned violins for much longer than I have will provide some practical answers for you.
Another question along this line. I read somewhere that we should bring our violins to get checked lit once a year to get the tuning pegs, soundpost, tailpiece, etc all checked out. Is this something we should do once a year?
It depends on the climate you live in. If you have large seasonal changes in humidity, you should do it at least once a year, possibly even twice a year. In California, where it stays dry all year, I can get away with a a checkup every two or three years.
My luthier does a quick 5-minute inspection free of charge every time I go in for any other service, so I get that quick check every time I have a bow rehaired (on average every 8-12 months) and get a cleaning and detailed check-up every 2 years or so.
