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.
The violin is the highest pitched instrument in the string section. It has a resonant lower register and can also reach extremely high notes. As with many orchestral instruments there is no definite top note - it all depends on the skill of the player. There are four strings, usually tuned to G3, D4, A4, E5.
