There are so many different kinds of violin strings available today.
There are basically three types: nylon strings, steel strings, and gut strings.
I often recommend Dominant strings from Thomastik
I think it’s good to use very standard strings like Dominant until you gain more experience.
I think Dominant works well or any violin and they sound good too.
First, you need to concentrate more on learning violin playing techniques, as well as develop some musicality, at least until you start to use a full-size violin.
After you get used to playing a full-size violin, you can certainly start trying different kinds of strings, depending on your preference, and see what kind of sound you want to produce.
I will talk more later about which strings I use, as well as some of my impressions of different strings. 😀
