How is a fiddle tuned differently from a violin?

A fiddle and a violin are typically tuned the same way, with both instruments using the standard tuning of G, D, A, and E. However, fiddlers may use alternative tunings to achieve specific sounds or facilitate certain styles, such as cross-tuning or open tunings. These variations can affect the instrument's timbre and the ease of playing certain folk or traditional music. Ultimately, the primary difference lies in the playing style and musical context rather than the tuning itself.
