Classifying Scandinavian tunes is an arbitrary activity.
Most of these tunes are played for dances, and the same tune can be used for
different dances. As a practical matter, many musicians group tunes
together by dance type (especially for gammaldans, the more recent
layer) and/or by region (especially for bygdedans, the older
layer). This is the method I have used. (See here for a brief discussion of folk music
basics.)
Most Scandinavian tunes do not have unique names that can be
used to identify them. Any individual tune may be listed in more than one
category. If you can't find something you're looking for, try searching
for its number (if you know it) or a relatively unique word from the title
or the dance type.
