My D string on violin sound like the sound of cutting forniture workshop. All strings are in tune though!?

i think you should change your strincs or your violin wooden bridge....mebbe idk tho

chuck the strings that are on it. They're terrible. Buy a real tuner, the online tuners aren't very good. Now, there comes a choice when you go to buy strings. There are many styles and brands to choose from, and many price ranges. They basically fall in two camps, orchestral style strings or fiddle style. Within those, there are myriad of styles and brands again, so I'd just get a reasonably priced set of fiddle strings. They're the same note wise, but are much more forgiving than orchestral style. They're great for beginners that may not have precise fingering and bowing techniques yet. They're a bit more pleasant to hear than improperly played orchestral strings, but only a bit. Might think about getting a mute too, so you can practice without making everyone around you want to throw something at you just to make you stop. You might buy everyone in your family their own earplugs and earprotectors, it would be the courteous thing to do. LOL>
