I have been tuning my fiddle successfully for the past year (had about 4 months of lessons). Now my fiddle has gone kapluie on me. First my bridge went flying and that had to be re-installed. Then the pegs kept loosening so I put on some peg drops on them. Then they were so tight one of the pegs snapped in half! Now, when I am getting close to the correct string tension and pitch the cord wrapped around the button at the base of the tail piece had totally let go. This has happened twice, each brass fitting pops off and everything goes flying! One would think that I have the strings too tight but the pitch is still too low and the strings need to be tighter. Do these parts wear out? Do I order a new cord and what is the official name of this part?. Sorry this is so long, I just want to practice my fiddle but I can't tune it. Thanks so much!!!!
I understand your frustration.
The pegs behavior is related with different factors. Most usual factors are:
Hope this was helpful to you.
Because multiple things are going wrong, it sounds to me like you need to pay a qualified violin repair technician to properly set up all the parts, and then give you some advice about how to keep these problems from recurring.
