By Laurie Niles: Violinists have been stringing their fiddles with "Dominants" for a half-century, and now Thomastik-Infeld aims to build on the popularity of its best-selling brand with a new line of strings called "Dominant Pro."
Pioneers of the synthetic core string, Thomastik-Infeld's original Dominants, launched in 1970, allowed for qualities of both steel strings (tuning stability and resistance to bow pressure) and gut strings (low tension and modulation capability) by using a synthetic core of very fine nylon fibers.
When it comes to the new Dominant Pros, "this new set was not aimed to change the basic character of Dominant, but rather to offer an additional, contemporary repertoire of strings," reads a statement by Thomastik-Infeld.
Generally, the new Dominant Pros tend to cost about $25 more than the regular Dominants (a quick check on the Internet shows Dominant Pro violin sets to run around $89; with old Dominant sets being about $64).
I have not personally tried them yet, but here are some of the characteristics that Thomastik-Infeld lists for the new strings:
Compared with regular Dominants, Thomastik-Infeld said that the Dominant Pros sound darker, more focused and respond more directly. They also project more powerfully, and the "break-in" period is supposed to be just a few hours, so they will be fully ready for performance within several hours of playing after re-stringing. You can read more about the new strings on this page by Thomastik-Infeld.
