Coruss Synthetic Bow Hair for Viola

£14 - £21 + postage: please scroll to bottom of page to order

Here's why so many players are leaving horsehair behind:

  • Hydrophobic: Low humidity uptake keeps Coruss stable regardless of ambient humidity.
  • Reliability: Unlike horsehair, Coruss is very durable.  It's innate resistance to heat and humidity slow its lengthening, allowing a rehair to last approximately twice as long as horse hair.
  • Preservation: Do you keep a spare hank in case an emergency rehair is needed when travelling?  Coruss won't degrade like horsehair when stored for long periods.
  • Strength: Coruss doesn't break under normal use.
  • Tone: In blind tests, even professional musicians can't distinguish Coruss from horsehair .  When informed which is playing, 85% preferred Coruss, whilst 100% believed Coruss produced a much more articulate sound.
  • Ethically sourced: Coruss bow hair uses no animal products.
  • Clarity of sound: Coruss is capable of producing subtle dynamics without any tonal distortion.
  • Practicality: Coruss is strung in exactly the same way as horsehair.
  • Choice of colour: Coruss is available in the following 
    White, Black, Red, Blue, Pink, Green, Orange

Pops bass rosin is essential for use with Coruss hair.  The texture of Coruss is significantly smoother than horse hair, consequently, standard rosins often don't stick well to the hair.  By applying a few strokes of Pops rosin as a base layer, your preferred rosin can be applied with ease.  Scroll down to order.


Coruss is strung in the same way as horsehair, but please check with your luthier if they're willing to use Coruss before placing an order.

For those outside of Cardiff who wish to have their bow rehaired by us, we offer a rehair by post service.  Send your bow via post or courier.  Please fill in the following form and send it with the bow: Right click here to save form.

Please make sure you send your bow in a solid container such as a drain pipe. Wrap it gently in bubble wrap, ensuring it isn't overtightened, as this can result in your bow bending during transport. Do not use cardboard tubes as they aren't strong enough.
