About This Item

D'Addario Octave Helicore Strings

The Helicore Octave Violin set is designed to be played one octave below traditional tuning for a new world of tonal and stylistic possibilities. It utilizes the same core technologies as the original violin set for quick bow response, comfortable playability, and clear sound.

NOTE: Please follow these guidelines for installation: Check that the grooves in your bridge and nut have room to accommodate the larger diameter of the octave strings. A too narrow groove could pinch the string and cause it to break. Excessive pressure or pinching may prevent normal movement. For best results, thoroughly apply graphite (pencil lead) to grooves before installing each string.

Asked On: 09/27/2020

I recently purchased a 3/4 viola and would like to have it an octave lower than my violin using these strings. The Instruments are same length the viola just a deeper body. Will this set work for the viola? Thanks.

SHAR Answer:

Hi Doug, thank you for your question! If your viola is the same length as a 4/4 violin, these strings should work just fine!

Are these strings as thick as viola strings? Would you recommend a viola bow given the extra thickness?

SHAR Answer:

Hi Terrel, thanks for your question. The octave strings are thicker and can benefit from the added mass of a viola bow to produce more projection. They can also be played with a violin bow and produce a wonderful tone. It really comes down to a player's personal preference for tone and bow feel. Hope this helps!

How does the string tension compare between the octave and standard strings?

SHAR Answer:

Hello Randy! There is not difference in tension, but the Octave strings are thicker in diameter. You will likely need to adjust your bridge and nut slightly to allow for their girth, but the tension should remain the same as a standard set of Helicore strings. Let us know if you have any other questions!
