Dominant Strings

These strings have a highly flexible, multi-strand nylon core. The resounding success of Dominant strings is due to its similarity in tone and response to gut strings, without gut's attendant drawbacks. The sound is full and mellow, yet rich in overtones. Its ability to project sound without being metallic comes to the fore both in arco and pizzicato. Also offers effortless response to intricate fingering and tuning stability even under extreme humidity and temperature conditions. Dominant strings should be changed at appropriate intervals to ensure continuity of tone color.

Dominants are NOT prone to breaking

"I am writing this review in response to other reviews. I've used Thomastik Dominants, mostly bought via Shar, for 36 years. I'm a professional violist and educator and I've never had a problem with Dominants or with Shar. Those people who are having repeated issues likely have an issue with their instrument having a sharp edge somewhere where they shouldn't. Some types of fine tuners have you loop the string over a sharp edge - this can cause breakage. Sometimes your string has dug into the bridge (the pressure of the strings over time can cause this) and it can cause a sharp edge there that causes breakage. I've seen many a poorly made nut (at the top of the fingerboard) that is sharp and causes breakage. This will happen more often with cheap instruments made with poor materials and workmanship. I don't use Dominants exclusively, but they are the string I've used most often in my career because they are reliable and long lasting. I strongly feel you can trust them. If you are having strings break repeatedly, see a reputable luthier (someone who specializes in string instruments only; not a store that sells every instrument under the sun) and my guess is they will be able to show you exactly why your string keeps breaking."

I've been looking for the best quality strings that bring out that deep rich sound. I just love the sound of the G and C strings. Don't get me wrong the A and D sound awesome too. The only thing I have to say that is pretty minor is that they have a hard time staying in tune the first day or two which is only natural. I am enjoying these strings and I hope you enjoy yours too. Thanks, Shar!

Excellent Viola Strings

I have been exclusively using Dominant strings on my Viola 16 inch for 8 years. These strings are very durable. In that time I have only had 2 A strings break at the ball. After 2 days they hold their tune very well when new. The G string is my favorite. Beautiful warm sound. I continue to use these strings and highly recommend them. They go on sale once in a while which is a bonus. I just ordered another set this week on sale, as my spare set. I usually change the strings every 18 months. I play most days..

Broken string

I am disappointed in quality of your strings Thomastik Infeld Dominant Viola String Set - Full Size - Medium Gauge. I ordered two sets at 95.99 plus tax for each. I had set put on my sons viola about 3 weeks later and about 2 weeks later a string broke. Fortunately, it didn't break during his audition. He had to replace the string with the spare string. According to your return policy we are not eligible for a return. I hope that the second strings last longer. How can we insure we are not receiving old strings?

Excellent, Reliable

I've been using these strings exclusively for more than a decade, and I have never had any issues with them. They have a clear tone, and balance warmth and brightness without sounding muddy. They're absolutely wonderful, and well worth the price of entry.

Viola A String is defective

In the past 3 months I have replaced four A strings on my viola. Of these, only one was eligible for replacement because I had purchased it within 30 days. These strings are breaking at the ball end (the fine tuner is not the problem, I have had it inspected), and the most recent break occurred during a concert. I love the sound of Dominants on my viola, but it's like playing a time bomb waiting for the A to break. I've switched to Jarger A (medium) which settled in to pitch quickly and is very responsive. From the reviews, it appears that I am not the only one who has had this problem and that the A strings are defective. Unfortunately, the warranty can't be applied to 3 of the strings because I've had them longer than 30 days.

Broken A strings...twice

In the last couple of years, I have purchased two sets of these strings, and the A strings on both sets broke....while in the case....and no, they were not strung too tight, were not exposed to big temp. changes, etc. I'm done with this brand. I even wrote a letter to Shar and received no response. I love the sound of the lower strings, but I can't keep having strings break for no reason.

A war-horse among strings

Trying different string brands and combinations is an expensive endeavor. And then there is the breaking-in time during which you begin to forget what the previous set sounded like. Dominants are the strings I have found to be the most successful across the widest range of violas. They are neither the brightest nor the darkest, the fastest nor the slowest-responding. They produce a clear, honest tone with a satisfactory response time on most instruments. They also have a reasonably long playing life. If you are on the inevitable quest for the perfect strings for your viola, start with Dominant (medium) D-G-C, and a Larsen or Jargar A-string. From there, you will be able to add or subtract strings/brands till you find your ultimate set-up.
