Since the release of World War 2 grand strategy game Hearts of Iron II, almost a decade ago, Paradox Development Studio has always set its games to original music by Andreas Waldetoft. But the original Hearts of Iron relied on pre-existing music — for instance, Wagner’s “Ride of the Valkyries”, Mussorgsky’s “The Great Gate of Kiev”, and this week’s theme, Rodrigo’s “Adagio”. While lovely, “Adagio” is neither heroic, nor bold, nor martial at all. It is melancholy and regretful (according to Wikipedia, one of Rodrigo’s inspirations was grief at his wife’s miscarriage), and perhaps that makes it appropriate for accompanying a game about World War 2. Worth thinking about while you listen to the song.
