Thanks for this guide. The bridge is considered to be an important part of the instrument and also said to be a soul of the instrument and its sound. The bridge should be always straight and perpendicular to the surface of the instrument. For some people, it may be difficult to replace the bridge all by their own, therefore it is necessary to take the violin to a violin shop where an experienced technician can either fix or replace the bridge. While the bridge is small and light, the way it is set up makes all the difference as far as how the violin will sound.
