Coruss Bow Hair

No reason to switch to synthetic bow hair?  Coruss not only matches horse hair's tonal quality in blind studies, it also possesses greater strength and durability!  

In fact the hair performs so well, it is the bow hair of choice for the award winning Orchestre de Chambre de Toulouse, especially when performing abroad.  Whether you're a touring musician, a vegan, someone seeking to save money on bow rehairs, you're concerned about animal welfare, or perhaps just want the novelty of playing a bow with coloured hair, Coruss is for you!

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

  • Hydrophobic: Low humidity uptake keeps Coruss stable regardless of ambient humidity.  Take note, touring musicians!
  • Reliability: Unlike horsehair, Coruss is very durable.  Its innate resistance to heat and humidity slow its lengthening, allowing a rehair to last a least three times 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, so your spare hank will last a lot longer!
  • Colour: Coruss is available in white, black and a range of colours (see gallery at bottom of page).
  • Strength: Coruss doesn't break under normal use like horse hair.
  • Tone: In blind tests, even professional musicians can't distinguish Coruss from horsehair .  When informed which is being played, 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.

Trevor Maplestone ( and amateur rosin researcher) has been experimenting with various rosins for several months to test which is most suited to Coruss and has observed the following:

"Preferred method so far:  I use Evah Pirazzi Gold and Olive Label as a pair of rosins. For a single choice, I would say Evah Pirazzi Gold is the best rosin, but a second rosin gives variation when you think your chosen rosin isn’t performing or you need something else.  On some performing days, before I go out, I put on a layer of Olive Label with some EP Gold on top."
The favourites so far based on the experiences of several customers:

  • Violin : Evah Pirazzi Gold and Olive
  • Viola : Evah Pirazzi Gold, Andrea Solo and Andrea Orchestra
  • Cello : Andrea Solo, Andrea Orchestra and A Picaccere
  • Double-Bass : Nymans and Pops

Rehairs by post

Unable to travel to the shop for a rehair?  No problem!  Send your bow via post or courier.  Please fill in the following form and send it with the bow: Right click here to download 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.

You can order Coruss bow hair from our online shop and ask your usual rehairer to fit it for you.  It is now available in colours! Click here to order!

The Coruss hair is really great and we love the strong sound it has produced. It's also nice to know, no harm has been done to animals in its making!

I get more sound without working so hard,… the response [is] better, the notes are more immediate.

[Coruss] has transformed an ordinary Snakewood Baroque violin bow into a very expensive feeling bow that plays effortlessly and with great precision. 
Gordon Ewan

I suppose in the same way that some excellent bows simply don’t work with some excellent violins - this might not be a solution for all outfits - but with its consistency, longevity and excellent value [Coruss is] definitely worth a try.
Oli Wilson-Dickson (ALAW, Jamie Smith’s Mabon, The Devil’s Violin)

They are super durable, and I haven't broken a single hair since I got them (and I used to break a lot!). What is really super about them is that they have all the qualities needed for playing more conventional as well…I will recommend Coruss bow hair to every player I meet, regardless of playing style!!!
Christian Meaas Svendsen, Norway,

I have a big problem with horse hair because it breaks a lot…..I have to rehair my bow every month, sometimes even more.  Fortunately if Coruss hair doesn't break so easily ( it didn't break so far), I think I found a solution.  It's better than I expected! It produces solid sound immediately as I touch the strings.
