Sized to fit 4/4 scale violin with a playing length of 13 inches (328mm), these medium tension strings are optimized to the needs of a majority of players. The Helicore Titanium-Wound Violin A String provides an alternative to the standard aluminum-wound Helicore A string. It is designed to stand up to rigorous playing, corrosive elements and fretted instruments. Frets often take their toll on aluminum strings, as aluminum is a softer metal. Additionally, the Titanium-Wound A provides a solution for violinists whose body chemistry is naturally corrosive to aluminum. The Titanium A String is tonally brighter, more focused, and thinner in diameter than its aluminum-wound counterpart, but retains the quick bow response and short settling time characteristic of other Helicore strings.
