This is a tune from Dalarna. It is a skänklåt, or gift-giving tune. This kind of tune, usually a march variant, is a ceremonial tune played when gifts are being presented, such as at a wedding.
This particular skänklåt is dedicated to the fiddler, and it might have been played at a dance when the fiddler was expecting money (or a drink?).
Here is a YouTube video of a small fiddlers’ team playing this tune at a school concert.
