Detail 01
D string only
You get one string. A four-string restring means buying G, D, A, and E separately.

Independent shopping perspective
A single 4/4 violin D string from Thomastik's Infeld Red series, hydronalium-wound. For players replacing one string 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
You get one string. A four-string restring means buying G, D, A, and E separately.
Detail 02
Scaled for a full-size violin. On a 3/4 or 1/2 instrument the winding lands in the wrong place.
Detail 03
Hydronalium is an aluminum-magnesium alloy, lighter than silver winding for the same string gauge.
Detail 04
Part of a matched family — pairing it with the same series keeps response even across strings.
Detail 05
Single-string pricing. Budget four times this if you are restringing the whole instrument.
