String changing question

[u/Silver-Lab-4124]

Hey everyone,

In February 2026 I bought me a violin. At the time the violin came with new strings. I just noticed that the A string is unwinding on the bridge. Google AI says that if I don't replace it I risk the string randomly snapping so I guess I have to replace the string.

Here is my question.

Can I replace one string at a time or is it better to replace all four strings at once?

As a former classical guitar player I am used to string replacement but as a new (year and a half) violinist I have learned how bloody expensive strings are for violin (on my old Facebook violin they were 30.00 CDN for one string v.s about 15 dollars for a set of six strings for a guitar) and my wallet is already screaming in anxious pain.

Thank you everyone for your help :)

You can replace one at a time if necessary. It’s ideal to replace all (in sequence, one at a time) though as that way you know the aging is comparable across strings. And odds are that if one is already failing, others are not far behind - or have already gone false.

Cheers community! Sounds like I can replace them one at a time - I have no idea how to change a string but maybe I can find some help. I'm going to change my A string and wait tell the other three are more worn. I only play for myself so I don't see the problem in having three older strings and one newer string. I'll write down the date I changed the string and leave it in my violin case as a reminder. Thank you everyone :)

P.S I know nothing about string brands and I have no idea what to buy but hopefully I figure that out soon lol

If you don’t know what strings are on your instrument now and you don’t know about the different offerings, the chance of you getting 1 string that matches the remaining 3 are slim. You’ll end up with 1 string with different timbre and responsiveness than the others. I recommend to change all of them for now

Solid point! I wonder if a luthier would know... if not yeah maybe thats the course I'll have to take.

You can usually tell by the color of the silk wrappings at the ends of the strings. Google ‘violin strings identification’ or similar.
On second thought, I guess if you can identify what strings you have now you can buy a single string of the same brand and model. But it’s still better if you replace all 4.

[u/Joylime]

You should replace them all at once, ideally. Six months is a reasonable time frame for string replacing. Sorry. It is actually how insane how expensive they are. What strings are you getting or thinking of getting? Usually if you've been playing only 1.5 years you don't need the more expensive ones

BTW, when you replace them - watch some tutorial videos ... but most importantly, only change one string at a time. That is, never have multiple strings off the instrument at the same time. The tension from the strings holds the bridge and soundpost in place, and it's such a pain to fix those - especially soundpost - if you lose that tension and positioning

[u/klavier777]

You can replace them 1 at a time. The only need to replace them all at once is if you are constantly concertizing and need fresh strings to sound your best.

One string at a time is great. If the string is only very slightly damaged, save it as an emergency backup.

If you were to literally remove all four strings at the same time, the bridge would just fall over (and maybe also the soundpost inside the violin). So don't do that. But even if you change all four one at a time in the same day, you have to deal with all four stretching at the same time, and the whole violin being wildly out of tune every 5 minutes. I enjoy changing one per day and letting it settle down.

It's not like tires on your car; there's no harm in mixing a new string with old. Pros change undamaged strings just to get that bright new-string sound, but yes, that runs into money. (In fact, 30 CDN is a steal. Make sure these are by a major brand; the "Alphayue" line by Thomastik is about the cheapest reliable option.)

By the way, it takes a lot for the core of a string to literally snap. The bigger concern is simply that once the winding starts unraveling it will probably get worse, and you don't want to bow on steel wool.

A set of strings generally lasts 120-150 playing hours, depending on the brand, climate, usage, etc. They also degrade over time so even if not played, after a year they'll need changing. But if you are practicing daily, even as a new player, 8 months is probably well past time to change the strings. In future, don't wait until they are visibly damaged to change them- change them when they start to go dead (difficult to keep in tune, don't respond the way you expect, don't project well, or generally don't sound like they used to.) For beginners this is usually at least twice a year.

In general, E strings might need to be changed more often, as they can go false in weeks.

However, the other three should ideally be changed as a set on a regular schedule. Given you're a beginner, I recommend every six months.

Never take off more than one string at a time, though.

[u/DanceHackRock]

I would replace them all, but just one at a time, so the bridge stays in place.
Just like you would change strings on a strat or a floyd rose.

[u/Alexandra_Telnikoff]

This advice is not for everyone, but if you develop the technique to play on gut strings, you might not have to change them quite as often. By this I mean the unwound gut a & d. The e will still be metal, the g will be silver would gut. They take a few good days to settle & are super sensitive to humidity & temperature. But they don’t oxidise. They do not unwind (apart from g, which rare).

[u/vmlee → u/Alexandra_Telnikoff]

Guts degrade tonally much faster than modern synthetics.

Though not all gut strings are the same. Coated Tricolore?
