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 viola is a stringed instrument slightly larger than the violin. The instrument plays the role of the alto member of the violin family, situated between the cello and the violin and with a richer, darker tone than the violin.
