This site is oriented primarily towards fiddlers (although most instruments are suitable for Scandinavian folk music).  A violin is typically tuned G D A E (lowest string first), but many other tunings are possible and are used commonly in Baroque music and for folk music -- this technique is called scordatura.  (For hardingfele, the typical tuning is A D A E, and alternative tunings are especially common.)

When playing in performance, there are practical considerations about changing the tuning of the violin, expecially if there are several fiddlers playing together.  Consequently, it can be convenient to play entire sets in the same tuning.  Below are examples of some tunes which share a common tuning, from which sets could be constructed.  Other tunes not listed here can also be played in some of these tunings -- experiment and see what works.

The most common alternative tuning for the violin is A D A E (also known as A-bas).  It is so common (and often optional) that no special list has been gathered here.
