When it comes to my viola, I'm a very particular person about what I put on it. Even replacing the bridge was a hassle. When I'm looking for a set of strings, I am looking for the best, but also something more affordable, and I am glad to say that I found it with D'addario's pro arte strings. The sound quality is great. It doesn't even feel like I have to break the strings in, just to replace them six months later. The tone quality is second to none. I absolutely recommend these strings to any violist.
