That's probably arguable if you're Italian or German or Finnish or Czech, but what Grieg is getting at is the concept that composers are shaped on an instinctive level by the landscape around them. For Grieg, the very remoteness of Norway's landscape symbolized the distancing he needed to counteract the Austro-German musical hegemony. Mountains, fjords and harsh winters concentrate the mind . What is trivial and commonplace is dwarfed by the power of nature. In his seminal Grieg: Music, Landscape and Norwegian Identity,(2006) Daniel M Grimley shows how landscape inspired a sense of identity that gave rise to concepts which would shape Norwegian culture. Speaking of Gangar op 54/2. Grimley demonstrates how Grieg develops a powerful structure by contrasting dynamic and static elements. "It is, arguably", he concludes, "the denial of personal subjectivity and the longing for transcendence that this systematic organisation and division of musical space creates that is the most powerful expression of Grieg’s landscape."
Everyone is going to have different ideas on any subject but that doesn't mean it's right to destroy anyone who doesn't agree. Now, thanks to the internet, ideas about community and identity are being redefined. Once we jostled on with others and at some level realized that no-one really is omnipotent. Now any nutcase can link to other nutters and convince themselves that their reality is more important than anyone else's. This new community reinforces absolutism, in poltics and everything else. In the moral vacuum of modern communications, perspective disappears, and with that tolerance and decency. And I don't mean just gunmen. Again, Norwegian myth to the rescue. Trolls don't venture forth, learn, develop. They are fools but they get their kicks from destroying travellers who do. They usually win because they operate thru networks of fellow trolls. Significantly, trolls live under bridges and travellers seek wide open spaces. Out in the mountains and in the vastness of nature, we're forced to realize how grubby bigotry can be.
I've written a lot over the years about what mountains signify in music, especially in Mahler. Please read HERE and HERE for example. Also please read here about Thorbjørn, who was a Traveller, in every sense.
