It's my understanding that the difference between a violin and a fiddle is the bridge. The bridge on a violin is flatter that the fingerboard. However, on a fiddle, the contour of the bridge is made to match the contour of the fingerboard.
Fiddle is another name for the bowed string musical instrument more often called a violin. It is also a colloquial term for the instrument used by players in all genres, including classical music. Fiddle playing, or fiddling, refers to various styles of music.
