Timbre for viola

The Timbre string set is the best that we have made so far, utilising all of our knowledge and experience. It combines gut-like sound and response with the extra projection and stability that synthetic strings can deliver.

The Warchal Timbre set is distributed only by a select network of luthiers and repairers. (The limited promotional series is available online here.)


Why we decided to sell Timbre only via luthiers?

There are several reasons why we decided to sell Timbre only via luthiers:

Timbre is the best product that we have designed so far. We would like to be sure that it will be installed properly. If you aren't sure about your set-up or how to install strings without damaging them, you can utilise the complimentary installation service.

Instead of searching for strings online we suggest that you spend a few minutes in a violin making workshop. Even the environment and smell is inspiring. You'll find helpful advice about choosing strings to suit your tonal and playing preferences and your instrument can be checked briefly at the same time.

Timbre strings delivered to luthiers have never been coiled so you can enjoy them at their optimum quality.

If your luthier or repairer doesn't stock Warchal Timbre strings then please let them know that ordering from us is simple. More information can be found on lep.warchal.com

String break-in time of only 15 minutes.

Though we have tried our best to give you a short string break-in time, we also need your help to enable the strings to reach their ultimate sound quality. After fitting Timbre strings we suggest that you play for 10 - 15 minutes using moderate dynamics. You may need to retune your strings several times during this period.

Check that the bridge angle is correct and adjust it carefully if needed, retuning afterwards.

If you find that the sound of the W-Core strings is warm but perhaps a little dull, or lacking in power and brilliance, then this can easily be rectified in a few seconds. Play at least four strokes of the bow on each string close to the bridge. Ideally you should use a slightly slanting but not tilted bowing angle as shown in the diagram.


Use a bold fortissimo that is louder and perhaps harsher than you might use when performing on stage. Retune again.

You are now able to enjoy almost all the sound quality of the Warchal Timbre strings. You will need to retune slightly over the course of the next few hours. Full tone quality is reached within about five hours of playing.

Never rub or heat our strings as part of your string break-in routine. We are aware that you may find information online that suggests you do this, but please do not.

To keep your Timbre strings responding at their best, make sure that you regularly clean rosin build up from your strings. Do not use liquid cleaners of any type to clean Warchal strings. Regular cleaning with a microfibre cloth is all that is needed. If you find that the rosin dust has become fused to the string then use a plastic card such as a credit card to scratch it off gently. You can find full cleaning recommendations here.

If your luthier or repairer does not stock Warchal Timbre strings then please let them know that ordering from us is simple. More information can be found here.
