Independent shopping perspective

The Korena take

Single Spirocore G string for 15-inch and larger violas. A steel-core replacement string, sold individually rather than as a set.

Strong match

Who this is for

  • Replacing a broken or dead G on a full-size viola
  • Players who want a steel core's focus and quick response
  • Topping up a set when only the G has gone

Consider the trade-offs

When to look elsewhere

  • Violas under 15 inches, which need a shorter string
  • Players wanting warm, gut-like tone from a synthetic core
  • Anyone needing a complete set, since this is one string

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

G string only

One string, not a set. You will need the other three separately if you are doing a full change.

Detail 02

15+ inch sizing

Cut for full-size violas measured 15 inches and up at the body. A shorter viola will leave too much slack.

Detail 03

Spirocore steel core

Steel gives a focused, direct sound and fast response, with less warmth than synthetic-core strings.

Detail 04

Steel core tuning stability

Steel settles fast and holds pitch well once stretched, so break-in takes hours rather than days.

Detail 05

Around $41 for one string

A full set of these runs well past a student string set. Budget accordingly if replacing all four.

Final check

Know before you order

  1. 01Measure your viola body length; under 15 inches means a different string
  2. 02Check whether your tailpiece has fine tuners, which steel strings benefit from
  3. 03Only the G is included; other strings are sold separately

Product questions

Before you decide

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

01Will this fit my 16-inch viola?

Yes. The 15+ inch designation covers full-size violas from 15 inches up, so a 16-inch instrument is within range.

02Can I mix this with strings from another set?

Yes, and many players do, though steel and synthetic cores respond differently under the bow. Expect the G to speak more directly than synthetic neighbors.

03How long does it take to settle in?

Steel core settles quickly. Expect it to hold pitch within a few hours of playing rather than the days a synthetic core can take.

04Does it come with a ball or loop end?

Check the end fitting against your tailpiece before installing. If your tailpiece has built-in fine tuners, confirm which end type they accept.
