I started looking at the Finnish tunes Jack Campin was nice enough to post here I'm looking at it from from back to front.
I got to Violan Marsurkka (3rd from last in the pdf) which is notated with dotted-eighth/sixteenths.
The examples I've found on Youtube, like this accordion one or this ensemble one seem
like they they are more like straight eighths.
Should this tune, or Masurkkas in general, be swung?
