Is there any standard width height or breadth for violin bridges. I think I over sanded my bridge but it was pretty cheap it came with a 200 dollar violin. Can I sand the bridge myself carefully? Can anyone recommend any bridges? Also something to keep my violin clean? Also is there any solution for the rosin sticking on to the bow and the hair? Is it possible to get genuine horsehair? I live in India so online options would be good as there are not many sores around here. Any other general tips would be great.
Standard dimensions of violin bridges: the strings should be about 12 mm apart at the bridge, and the height of the bridge should be such that the G string is about 5.5 mm above the end of the fingerboard, the E string about 3.5 mm, the others in between, such that the curve makes it possible to bow all strings separately easily. This is subject to variation, depending on the violin and musical taste.
Keep your violin clean with a clean cloth. You shouldn't need any cleaning fluid if you do it every time after playing. Anything that will dissolve rosin might also remove varnish. If necessary (on your own responsibility) you can use a cloth with water and a bit of alcohol. Use care.
