The main difference between a violin and a fiddle is simply the style of music that is played on them. The instrument itself is the same, with four strings and a similar shape. However, a violin is typically used to play classical music, while a fiddle is used in traditional folk music, such as bluegrass or country.
Fiddle players often use a different technique than violin players, with more emphasis on bowing and playing with a looser, more energetic style. The term "fiddle" also has a more colloquial, down-to-earth connotation, whereas "violin" may sound more formal or high-brow.
