D'Addario DZ312 4/4M A Violin Strings

Zyex Violin Single A String — Warm Synthetic-Core A for Full-Size Violins

The D'Addario Zyex Violin Single A String is a standalone A string designed for full-size 4/4 violins, built on a synthetic Zyex multifilament core rather than traditional gut or steel. Zyex is a next-generation synthetic material that produces a warm, rich tone with a broader tonal palette than most other synthetic-core strings, while remaining clear and powerful under the bow. Because the core is synthetic rather than gut, the string is remarkably stable under drastic climatic changes — humidity and temperature swings that would send a gut string out of tune stay largely under control. Within a matter of hours of fitting, the A settles in on the instrument and reaches its working voice, making it a practical choice for players who want synthetic-core consistency on a single string. Packaged in a uniquely designed sealed pouch, the string is protected from the elements that cause corrosion between the factory and the moment it goes on the instrument.

Who It's For

The Zyex Single A String is the right choice for violinists who already run a Zyex set and need to replace a worn or broken A without buying a full set, as well as players looking to try a synthetic-core A on a bright-sounding instrument that needs taming. Medium tension suits the majority of players and pairs well with a wide range of violins, especially those that lean bright or balanced. Students benefit from the short break-in time and stable tuning, intermediate players get a warm, responsive voice that broadens their tonal palette, and professionals value the climatic stability for stage and travel use. The sealed-pouch packaging keeps the string factory-fresh until the moment of fitting on any 4/4 violin.
