D'AddarioHelicore Viola E String 16 in. Plus Heavy
Independent shopping perspective
The Korena take
A single heavy-gauge E string for a 16-inch-plus viola. For players running a five-string setup or an extended upper tuning.
Strong match
Who this is for
- Five-string viola players needing a dedicated top E
- Replacing one broken E rather than a whole set
- Violas measuring 16 inches or larger
Consider the trade-offs
When to look elsewhere
- Players needing a standard C-G-D-A viola set
- Smaller violas under 16 inches
- Anyone wanting lower tension under the bow
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
Medium at 22.4 lbs., light at 20.4 lbs.
Heavy sits about 2.6 lbs. above medium, enough to change bow feel and top pressure.
Detail 03
16 in. Plus
Cut for full-size violas 16 inches and up. A shorter body leaves excess string past the peg.
Detail 04
E string
Not part of standard viola tuning. This is for a five-string instrument or an extended upper range.
Detail 05
Sold as one string
You get the E only. Mixing it with worn strings will leave an obvious tonal mismatch.
Final check
Know before you order
- 01Single string, not a set. Buy the other three or four separately
- 02Measure body length first, 16 inches or more
- 03Heavy tension adds load, check the bridge and soundpost are sound
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Does this come as a full set?
No. This is the E string on its own. If your other strings are worn, replace them at the same time so the instrument sounds even across the range.
02Will it fit my 15-inch viola?
No. It is cut for 16-inch and larger violas. On a shorter body the winding length will not line up correctly.
03What is the difference between heavy and medium?
Heavy pulls 25 lbs. against 22.4 lbs. for medium. Expect more volume and more resistance, with a slightly slower response.
04Why does a viola need an E string?
Standard viola tuning is C-G-D-A. An E is used on five-string violas or when a player extends the upper range beyond the A.
