Strings are one of the most important parts of the viola as they, when combined with a bow, ultimately produce the beautiful tones that violas are known for so it is therefore it is vital for you to pick the best viola strings.

There is no one viola string that sounds great on all violas since each viola is unique. We recommend trying several different viola strings to understand which strings make your viola sing. Our list below includes viola strings that are rated highest by players, but you will need to find the best viola strings for your viola from this list.

Viola String Types

Like violin strings, cello strings come in three types as well — Gut core, Synthetic core and Steel core.


These strings are made from the gut lining of sheep. Gut strings were the only strings available for the first several centuries of string instrument existence. Known for having the warmest sounds – and considered the most complex and with rich overtones – gut strings are almost exclusively used by professional classical musicians.

The other side of those rich, complex tones is that strings made from gut take the longest to settle in on your instrument. They are more sensitive to variations in temperature and humidity than other options and are known to slip out of tune easily. If you’re newer to the cello, gut strings are not the best option for you because you need to have a very keen ear and attention to detail in order to manipulate and play these strings consistently and with expertise. Also, gut strings aren’t as long-lasting as steel core or synthetic core options.

Another consideration when it comes to sound is that gut core strings are slower to respond and have much softer tones, which means they aren’t as suited to the cello unless you’re playing a baroque instrument and/or are looking specifically for that sound in your music.


Also referred to as “all metal” strings, steel core strings are made from straight or twisted metal wire. They are the most durable of all the cello string options and are also the most stable. Steel core strings provide stable pitch and are known for producing the highest volume. 

They are the preferred string for most jazz, country or folk players – who need a crisp, loud and consistent sound to shine through the other instrumentation. They’re also the ideal choice for electric cellos. Since steel core strings are the least expensive of all the options, they’re also a wise choice for beginning players and students – much easier on the budget.


These strings were invented in the 1970s in an effort to replicate the tones produced by gut core strings without all of their inconsistencies. As a result, synthetic core strings sound wonderful, settle in after just a day or two, and are not nearly as sensitive to temperature and humidity fluctuations.

Synthetic core strings are made using a synthetic fiber, Kevlar, or a type of nylon, Perlon. These materials are wound up outside the core with an amalgam of metals – such as chrome steel, aluminum, tungsten, silver or gold.

Viola String Gauge

Light, medium and heavy are the most commonly made cello string gauges, but some companies offer more variations, using gauge numbers. The rule of thumb is, a thicker string produces more tone, but has a slower response; a thinner string is delivers a faster response, but with the trade off of a thinner, lower volume sound.

Medium gauges cello strings are definitely the most common, but of course every instrument and player is unique, and you must discover which gauge works best for you.

In no particular order, these following string set are the most popular ones and should be the first ones you decide to try.

Thomastik-Infeld Dominants are one of the most popular strings due to their flexibility and stable, warm pitch. Personally, I use Dominants for my D, G, C strings and combine with a Jargar A. Despite their steeper price, Dominants have a very long life making them a great choice. They come in a variety of lengths and gauges, so again there is a lot of flexibility.

Dominants were the first strings manufactured with a synthetic perlon or nylon core and have become a measuring stick against which most other synthetic viola strings are measured.
