I see countries just use either the major or minor scale. But I'm wondering if someone knows of a country that uses another mode (apart from major and minor scale) for their anthem?
This Wikipedia entry on national anthems notes that most national anthems use a major scale tonality. A number of exceptions which use a minor tonality are listed.
But there is also a list of national anthems which use a pentatonic scale for fundamental material, as well as a list of anthems which use "unique modes/modulations."
A couple of particular examples: "Kimgayo", the national anthem of Japan, uses a pentatonic scale, while "Garaşsyz, Bitarap Türkmenistanyň Döwlet Gimni", the national anthem of Turkmenistan, uses the Mixolydian mode.
