Independent shopping perspective
The Korena take
Single A string for 4/4 violin from Thomastik's Peter Infeld line. For players replacing one string on an existing set.
Strong match
Who this is for
- Replacing a worn or broken A without buying a whole set
- Violinists already running Peter Infeld strings
- Keeping a backup A in the case
Consider the trade-offs
When to look elsewhere
- Players needing a complete set — this is one string
- Fractional-size violins; 4/4 length won't fit
- Viola or cello players
What matters in use
The specifications, translated
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 02
A string only
Single string. A fresh A next to three older strings will sound brighter until it matures.
Detail 03
Peter Infeld line
Thomastik's higher-tier violin line, priced above their standard offerings for a single string.
Detail 04
Synthetic core
Settles faster than plain steel and gives a rounder tone under the bow than steel-core alternatives.

Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Does this come with the other strings?
No. This is the A string alone. The G, D and E are sold separately.
02Will it fit a 3/4 violin?
No. This is sized for a full 4/4 violin. A shorter instrument needs a fractional-length string.
03How often should I replace a violin A?
Depends on play time. Heavy daily practice usually means a few months before tone goes dull and response softens.
04Can I mix this with a different brand set?
You can, though tension and tone across strings will be less even than a matched set.
