Hey Isabel, I never heard that! I’m not sure it’s not an old wives tale. Either way, sweaty hands (whether you drink soda or not) cause the E string to ‘darken’. When it becomes discolored like that, definitely time to change the E string.
Meanwhile, here are a few fun facts about the violin:
1) The violin is made up of over 70 pieces of wood.
2) Violin strings were first made of sheep gut (commonly known as catgut).
3) Violin bows typically contain 150 to 200 hairs.
4) You burn 170 calories per hour playing violin. (Do you play at least an hour? 🙂
It will be a fun thread, if everyone does a little research to find an interesting trivia fact about the violin!
