The smallest difference will change the sound of the violin. Musicians sometimes think that this was the secret of the Italians. Maybe they understood more than we do about how to cut the wood.

But the new violins still do not sound as good as the old one. Some scientists think the secret may be the varnish, which covers the wood of the violin and makes it look shiny.
