D string unwinding at the bridge??

June 11, 2017, 2:50 PM · For the last two sets of strings I've put on my violin, the d string has unwound at the bridge each time. I do follow the recommendation of using pencil graphite on the bridge and nut to prevent unwinding, but it doesn't seem to help. Any way to prevent this from happening anymore? I don't want to start a habit of putting new strings on once a month, as this happens frequently and is costly as well.

There are a few causes for string unwinding but especially in something as thick as a D string, I would think that the bridge slot is either too narrow and friction-destroying the string, or the D string itself is too heavy gauge.

There is also the option I believe for parchment, a little piece of material that is placed on the grooves of the bridge and stops wearing down of the string. However, that is only usually necessary for E strings, so I would still recommend getting it (the D string and the grooves on the bridge) checked out by your local violin shop.

Hope this helps!
