FAQ

Common questions about identifying strings

What is the String Finder?

It is Azzato’s free tool for identifying a violin, viola or cello string: you enter the silk colors at both ends, and it lists the matching models, brand by brand. No account or sign-up needed.

Are silk colors the same across all manufacturers?

No. Every manufacturer has its own code, and the colors also change from one instrument to another for the same model. That is why this tool works brand by brand and instrument by instrument, and never carries one over to another.

Where do I look for the color on the string?

At both ends. The silks are the colored threads wound at the pegbox end and at the tailpiece end. Both matter: two models can share the same color at one end and differ at the other.

What if the string has no silk left, or it has faded?

Colour identification no longer works. Bring the string to either of our two shops: our luthiers recognise it by gauge, material and winding.

What are the notes of the violin, viola and cello strings?

The violin is tuned G, D, A, E, from lowest to highest. The viola and the cello are both tuned C, G, D, A, the cello an octave below the viola. With most manufacturers, the silk color changes from one string to the next: that is how you can tell which note you are holding.

Does the tool cover harp and guitar?

No: it covers violin, viola and cello, the three instruments for which manufacturers publish a color chart. For the harp we have a separate tool, based on the Savarez table.
