Helicore: a modern benchmark from D'Addario for response and stability
Within the D'Addario range, Helicore viola strings stand out due to their multi-filament steel core construction, designed to offer consistent playability and reliable tuning stability. This C string in the "Long Scale" version meets the needs of larger violas while maintaining a uniform feel under the bow.
For whom and which styles?
This string is aimed at the vast majority of violists seeking a versatile Medium tension. Its profile suits both the classical repertoire (orchestra, chamber music) and more modern playing styles, thanks to a clear response and good definition.
Sound characteristics
The multi-filament steel core provides a clean attack and a quick response, particularly appreciated in bow articulations. The tungsten and silver winding promotes a solid C string with a warm foundation and clarity that helps the lower register remain distinct, while maintaining good tuning stability.
Recommended compatible accessories
To extend the string's lifespan, a soft cloth (for wiping after playing) and careful application at the nut and bridge are recommended to limit wear and optimize tuning stability.
