Product studyD'Addario Prelude Series Viola D String 15+ Medium Scale

Strong match

Who this is for

  • Student violas 15 inches and up
  • Replacing a dead or false D mid-set
  • Stocking spares for a school orchestra program

Consider the trade-offs

When to look elsewhere

  • Violas under 15 inches — the scale is too short
  • Players chasing a darker synthetic-core sound
  • Anyone needing all four strings replaced

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 01

15+ inch scale

Sized for violas with a 15-inch or larger body. Shorter violas need the short-scale version.

Detail 02

Medium gauge

Standard tension. Balances volume and left-hand effort, and matches the rest of a medium Prelude set.

Detail 03

D string only

One string. Pairing a new D with three old strings can leave the D noticeably brighter until it settles.

Detail 04

Prelude series

The student tier — chosen for tuning stability and long life rather than tonal color.

Final check

Know before you order

  1. 01Measure your viola body first; under 15 inches needs a different string length
  2. 02Sold as one string, not a set
  3. 03Expect a few days of retuning while the new string stretches in

Product questions

Before you decide

Straight answers to the questions shoppers most often ask about this product.

01How do I measure my viola size?

Measure the back of the body from the top edge to the bottom edge, not including the neck. If it is 15 inches or more, this fits.

02Can I use this on a violin?

No. Viola strings are longer and tuned lower. A violin needs violin strings.

03Should I replace all four at once?

If the others are old, yes — a single new string will sound brighter and louder than its neighbors until they are all matched.

04What does medium gauge change?

Tension. Medium is the standard middle ground; it feels normal under the fingers and matches other medium strings in a set.
