A National Anthem is a song of patriotic sentiment affirming loyalty to one’s country or nation adopted officially by that Country or Nation. An anthem becomes a national anthem through Constitutional provision, specific legislation or long – standing tradition.
Stylistically the majority of anthems are marches or hymns.They are usually written or composed in the most common language in the Country.There are however some notable exceptions to this rule particularly in multi-ethnic nations.
