Detail 01
Single string, not a set
You get the fourth string only. If the rest of the set is old, the new one will sound brighter and mismatched.

Independent shopping perspective
Single D-4 string from D'Addario's Pro-Arte Composites set, normal tension. A replacement for classical players who break or wear one string.

The core material differs from plain nylon, aimed at more consistent intonation on the wound bass strings.

Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
No. Classical strings are built for nylon-string guitars, which are made for lower string tension and use a tie-block bridge rather than bridge pins.
The fourth string, counting from the thinnest. On a standard classical guitar it is the highest-pitched of the three wound bass strings, tuned to D.
Fine if the rest of the set is fresh and you broke this one. If the whole set is worn, a single new string will stand out in tone and volume.
The middle tension option. It sits easier under the right hand than hard tension and gives moderate volume and action, which suits most players.
