The plain DOMINANT PRO E-string NO.DP01 [diameter 0.265 mm, 8.0 kg, removable ball end] with a core of carbon steel is tin-plated. A protective layer of nickel is placed between the outer coating of tin and the steel core in order to increase the corrosion resistance compared with conventional tin-plated strings. However, the corrosion resistance is lower than that of plain stainless steel strings (NO.129) as well as the stainless steel strings with gold and platinum plating (e.g.: NO.DP01AU, NO.DP01PT).

The string has a very good response, barely whistles, and is well-balanced in its brilliance and warmth. It supports the equilibrium with the A-string and promotes its capacity to carry sound. For musicians who prefer a high resistance to bow pressure, strings have to be extremely resilient. To ensure this, manufacturers often set store by a high string tension, among other things. As a general rule: the greater the diameter of a plain, unwound steel string, the higher the string tension. However, from a diameter of 0.273 mm onward, the string tension is usually so high that the strings can put excessive strain on the instrument, resulting in a loss of sound color.

Thanks to a specially developed wire treatment, however, we have succeeded in creating E-strings like the DOMINANT PRO NO.DP01, which offers a high level of resistance to bow pressure already at 0.265 mm with no loss of color or strain on the instrument. This wire treatment makes the sound soft enough that it does not have a screeching effect, and brilliant enough that it offers sufficient radiance, projection and resistance to bow pressure. As a result, the string sounds broad and brilliant even without applying much pressure. 

Technical Details:

NO.DP01AU [diameter 0.265 mm, 8.0 kg, removable ball end] generates a very warm, clear sound that simultaneously conveys brilliance. In addition, the string is extremely corrosion-resistant. In contrast to NO.DP01, the sound is as clear as a bell and the individual sound colors can be clearly and individually distinguished: green and blue remain green and blue without morphing into a tonal turquoise; yellow and red do not merge to become orange.

Combined with its great capacity for projection, this allows it to assert itself very well in orchestras or in chamber music as required. If the system as a whole (instrument, rosin, bow hair and bowing) has a tendency to whistle, NO.DP01AU may not be the ideal choice. In this case we recommend NO.DP01.

Important: the assumption that individual bowing alone leads to whistling is incorrect. As always, when using a fine tuner hook, it is crucial to make sure that it is always “deburred” (= the sharp edges are filed down), otherwise the string at the fine tuner end can break more easily than normal tin-plated strings.

Technical Details:

Of all the E-strings described, NO.DP01PT [diameter 0.268 mm, 8.2 kg, removable ball end] has the greatest projection capacity. It combines the clarity of the gold-plated NO.DP01AU with the response of the tin-plated NO.DP01. Like NO.DP01AU, NO.DP01PT is also extremely corrosion-resistant, but has less of a tendency to whistle and offers more brilliance in comparison. Due to its outstanding projection capability and clarity, it can be unsuitable for sensitive ears.

As a result of its larger diameter (0.268 mm as opposed to NO.DP01 and NO.DP01AU with 0.265 mm), it offers more resistance to bow pressure and is also better suited to a very low string position.

Tip: players must also be careful when using a fine tuner hook with NO.DP01PT , and always ensure that the sharp edges are rounded down.

Technical Details:

In comparison to the other E-strings, NO.DP01SN [diameter 0.262 mm, 7.9 kg, removable ball end] has a smaller diameter and is therefore ideally suited to instruments with a normal or high string position (high bridge or lowered fingerboard). In comparison to the standard NO.DP01, NO.DP01SN is not underlaid with nickel and is therefore somewhat more susceptible to corrosion. Thanks to a thicker layer of tin, however, it sounds warmer than NO.DP01 and much warmer than NO.DP01AU and NO.DP01PT.

NO.DP01SN also has the lowest string tension of all DOMINANT PRO E-strings, which means that almost no strain is exerted on the instruments and they can be greatly opened in terms of sound. This leads to a good bow response and also promotes the instrument’s radiance. Its low string tension means that it has the lowest resistance to bow pressure of all the DOMINANT PRO E-strings. 

Technical Details:

The DOMINANT PRO A-string NO.DP02 [5.5 kg] with aluminum winding was designed to have more tonal core and energy in the keynote. Its metallic component is slightly lower, but it still projects sound beautifully and also responds very well in pianopianissimo ppp with a consistently high capacity for modulation.

The string is very colorful, possesses a good balance between brilliance and warmth, an excellent response as well as good resistance to bow pressure. When combined with the E-string NO.DP01, it sounds even broader and more richly colored. 

Technical Details:

In comparison to NO.DP02 [5.5 kg], the NO.DP02B [6.1 kg, removable ball end] has a considerably smaller diameter. This means that NO.DP02B responds much faster than NO.DP02. Due to the steel core, the string achieves pitch stability immediately after being strung and offers a very high level of resistance to bow pressure. In addition, the chrome winding makes it extremely corrosion-resistant and bestows the string with a particularly long lifespan. Should a player have problems with the lifespan of synthetic A-strings in general due to aggressive sweating, NO.DP02B is the ideal solution.  It also reduces buzz tones (= small wolf tone).

It has a higher dynamic range (= can be played very quietly and very loudly) than NO.DP02,  however, it also features a decreased tonal modulation capacity, which is a typical characteristic of a steel string. Both strings have a very good brilliance to warmth ratio. After a break-in period of around five hours, NO.DP02B becomes a touch more brilliant and open. This supports the brilliance of the E-string, but can also induce whistling in sensitive E-strings such as NO.DP01AU or NO.DP01PT. However, NO.DP01 is not influenced by this.

In general, steel core strings have a higher string tension; this must also be taken into consideration with NO.DP02B so as to avoid potentially overburdening the instrument. When deciding on the NO.DP02B, we recommend using a fine tuner, since even the smallest of changes when winding up a string can result in extreme changes in the frequency, similarly to a steel E-string. 

Technical Details:

The D-string is the violin’s leading string. Accordingly, it has a very strong influence on the remaining strings in all aspects of play. The tonal lifespan of the entire violin string set is chiefly dependent upon this string. With the help of a novel silver alloy, we were able to combine the advantages of a silver string with those of an aluminum string in the DOMINANT PRO NO.DP03A [4.5 kg], while also eliminating their drawbacks.

What this means is that the DOMINANT PRO D-string offers a very refined bow noise, brilliance and pronounced sound color with a good deal of modulation capacity. This combination guarantees an ideal ability to sustain sound and projection in halls. Unlike conventional silver D-strings, it has a more direct bow response and does a better job of suppressing wolf tones in combination with the new G-string. The diameter is somewhat smaller than that of a synthetic A-string. This makes the string pleasant to play and means that it feels at once both supple and resilient beneath the left and right hand. 

Technical Details:

For musicians who prefer a larger D-string diameter, the aluminum-wound NO.DP03 [4.6 kg] offers an alternative to the thinner NO.DP03A. The diameter lies between that of the Dominant Pro A- and G-string. The sound characteristics are similar to the silver-wound NO.DP03A; however, the bow noise is coarser, the response more direct, and brilliance and projection capacity are increased. The decision swings somewhat more in favor of NO.DP03 if the feel of a thicker string is preferred.

Technical Details:

The DOMINANT PRO G-string NO.DP04 [4.6 kg] has a very low metallic component, less bow noise, and a more direct response. It is a good fit for the majority of new and old instruments and is ideally suited for soloists, chamber musicians, and use in orchestras. Due to the slightly increased string tension (compare this with DOMINANT NO.133 at 4.5 kg), it also offers increased resistance to bow pressure without putting too much strain on the instrument. The new string feels soft beneath the fingers, but stands out with its high resistance to bow pressure with an extreme capacity to sustain sound and outstanding radiance.

Immediately after stringing, the string set sounds bell-like and fills the room. In the first three to five hours of playing, the strings feel a touch softer and sound a little warmer than they do for the rest of their lifespan. Then the strings open up, sound more brilliant and open, and feel a little tighter beneath the fingers. The bell-like sound that fills the room decreases slightly in the last third of the strings’ life and they sound more direct – from this point on, the tonal character of the strings barely changes.
