Synthetic bow hairCoruss, the new generation
of bow hair.

Over the course of 30 years’ playing in concerts all over the world, in all sorts of venues, involving a great deal of travelling, I found that the way natural horsehair reacted to variations in humidity often caused me problems. When the bow hair has absorbed so much moisture that it can’t be sufficiently tightened, this really makes playing a lot harder.

Coruss carbon bows

Our bows
Coruss’ natural, organic rosin


Rosin is a key component, acting as the interface between bow hair and strings. Coruss bow hair merits its own, specific rosin. We have chosen the very best ingredients in order to be able to offer you the best playing experience, time after time.
