The musical instrument often referred to as a "fiddle" is the violin. While the terms "violin" and "fiddle" refer to the same instrument, "fiddle" is commonly used in folk, country, and bluegrass music. The distinction often lies in the style of music being played, with fiddlers typically emphasizing a more lively and improvisational approach. This instrument has a long history and is made of wood, featuring four strings and a bow, producing a range of tones suitable for various musical genres.
