What I find interesting when I look at traditional songs in Scandinavian culture is that they almost always celebrate nature. There are many, many examples of this. Scandinavians have a great love and respect for nature.
The Swedish national anthem for instance, 'Du Gamla, du Fria':
”You ancient, you free, you mountainous north
You quiet, you joyful beauty!
I greet you, loveliest land upon Earth,
Your sun, your sky, your green meadows. ”
At the celebration of Walpurgis Night at the end of April we all sing: 'Sköna maj välkommen =We welcome you fair month of May
this traditional song celebrates that the long winter months are over.
It is also interesting that music is compulsory in Swedish schools and emphasises music making, vocal as well as instrument-based, as the core activity of the subject.
