D'Addario DZ313A 4/4M D Violin Strings

Warm, Stable Tone for the D String Slot

The D'Addario Zyex Violin Single Aluminum D String is a standalone replacement designed for 4/4 scale violins, serving as a direct swap for the D string in the Zyex family. Built around a stranded steel core with an aluminum winding, it delivers a warm, rich character that balances brightness and depth. The string settles in on the instrument within a matter of hours, making it a practical upgrade for players who want consistent tone without a long break-in period. Its aluminum winding provides a slightly mellower response compared to silver-wound alternatives, making it well suited to instruments that lean naturally bright. Manufactured in D'Addario's New York production facility, this single D string meets the same quality standards as the full Zyex set and pairs well with a wide variety of violins.

Who It's For

The Zyex Single Aluminum D String is the right choice for violinists who need a warm, responsive D string that performs reliably across different playing environments. Students moving up from beginner strings will appreciate the short break-in time and the rich tone that helps develop ear training. Intermediate and professional players benefit from the string's stability under drastic climatic changes—ideal for touring musicians and players in regions with variable humidity. The medium tension suits the majority of players and pairs well with a wide variety of instruments, including those with naturally bright tonal characteristics that need taming. The ball-end fitting is compatible with standard fine tuners found on most 4/4 violins, and the aluminum winding offers a slightly warmer alternative to silver-wound D strings for players seeking a mellower sound profile.
