Detail 01
Long scale, 16+ viola
Sized by body length, not by feel. A 15-inch viola needs the shorter version or the winding lands wrong.

D'AddarioZyex Series Viola D String 16+ Long Scale Light
Independent shopping perspective
The Korena take
A single light-gauge D string for violas 16 inches and up. For players replacing one worn string or lowering tension on a full-size viola.
Strong match
Who this is for
- Violas measuring 16 inches or more in body length
- Players who want lower tension under the left hand
- Replacing a single dead or broken D string
Consider the trade-offs
When to look elsewhere
- Smaller violas under 16 inches — wrong string length
- Players who want a full matched set at once
- Anyone wanting maximum volume and push
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
Light gauge
Lower tension. Easier to press and bow, quicker response, but less power under a heavy bow arm.
Detail 03
Zyex synthetic core
Holds pitch better than gut through temperature and humidity swings, and settles in within days rather than weeks.
Detail 04
Single D string
You get one string, not four. Mixing series across a set shifts the balance between neighbouring strings.
Detail 05
D string position
Middle-low voice on a viola. Changes here are more audible in warm-register passages than on the A.
Final check
Know before you order
- 01Measure body length from the neck heel to the bottom edge before ordering
- 02One string only — a full set means buying the other three
- 03Expect several days of stretching and retuning before pitch holds
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit a 15-inch viola?
No. This is cut for violas 16 inches and larger. A 15-inch instrument needs the shorter-scale version, or the wound section will sit past the nut or bridge.
02Is this one string or a full set?
One D string only. If you are replacing everything, you need three more strings to complete the set.
03How long before it stays in tune?
Usually a few days of daily playing and retuning. Synthetic cores settle faster than gut but still stretch at first.
04Light or medium gauge — which should I pick?
Light gives lower tension and an easier left hand. Medium pushes more volume. If your viola already sounds tight or harsh, light is the safer change.
