Matarvals till jul

When I was 17 (I think) I made my first nyckelharpa tune. It was this waltz and I had no direct idea about anything (I first started playing the harp when I was 16).
I thought it was cool that I had made a tune so I played it for someone who visited us that night. The comment I got was "but that's not a tune you made, it's Now it's a famous christmas tune made by Alice Tegnér".
I was terribly disappointed and never played it again.
Now when I'm looking for some simple songs for key harp lessons, I happened to find this one on a piece of paper. I'm the worst in the world at writing sheet music, but I could still make out that it was this tune.
Of course, it's a Christmas song, but there are lots of other folk music tunes based on christmast songs, so maybe this one can also be included.
(What's handy about this song is that you don't need a special hairstyle to play it, anything works!)
