Detail 01
Single D string
Only the D. Your other three stay put, so expect the new one to sit slightly brighter until it settles.

Independent shopping perspective
A single aluminum-wound D string for 4/4 violin, from Thomastik's Vision Solo line. For players replacing a worn D rather than a full set.

What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 01
Only the D. Your other three stay put, so expect the new one to sit slightly brighter until it settles.
Detail 02
Aluminum-wound D is the common choice for clarity. Silver-wound Ds read warmer and thicker under the finger.
Detail 03
Cut for a full-size violin. A fractional instrument needs a shorter string or the ball end sits wrong.
Detail 04
Mixing lines across one violin makes the strings feel uneven bow to bow. Match your other three if possible.
Detail 05
Single-string pricing. If the A and E are also tired, a full set generally works out better.

Product questions
Straight answers to the questions shoppers most often ask about this product.
Aluminum. If your current D is silver-wound, this one will read a little clearer and less thick by comparison.
No. It is cut for 4/4. A fractional violin needs the matching smaller size.
It will play, but tension and feel vary between lines, so the D may sit unevenly against your other three under the bow.
Usually a few days of playing. Retune often at first, as new strings stretch and drop in pitch repeatedly.
