Detail 01
Single D string, not a set
One string only. If your other three are worn, a fresh D will sound noticeably brighter and mismatched.

Independent shopping perspective
A single aluminum-wound D string for 4/4 violin, from Thomastik's Peter Infeld line. For replacing a broken or dead D without buying 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
One string only. If your other three are worn, a fresh D will sound noticeably brighter and mismatched.
Detail 02
Lighter and clearer than a silver-wound D, with quicker response. Silver gives more warmth and body.
Detail 03
Full-size violin only. It will be too long and wrong in tension for 3/4 or smaller instruments.
Detail 04
Thomastik's synthetic-core premium line. Mixing it with a different brand's strings changes the balance across the instrument.
Detail 05
Aluminum windings can corrode with sweaty hands, dulling faster than silver for some players.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
One string — the D. If you need E, A, and G as well, buy the full set rather than four singles.
Aluminum is brighter and responds faster; silver is warmer and heavier under the bow. Aluminum is the more common choice on this line.
No. This is cut and tensioned for a 4/4 instrument. On a smaller violin the length and tension will both be wrong.
Synthetic-core strings usually stretch for a few days. Expect to retune several times a session at first, then it stabilizes.
