Austrian girl singing nepali national anthem

A national anthem (also national hymn, national song etc.) is a generally patriotic musical composition that evokes and eulogizes the history, traditions and struggles of its people, recognized either by a nation's government as the official national song, or by convention through use by the people. The majority of national anthems are either marches or hymns in style. The countries of Latin America tend towards more operatic pieces, while a handful of countries use a simple fanfare.Although national anthems are usually in the most common language of the country, whether de facto or official, there are notable exceptions. India's anthem, Jana Gana Mana, is in a highly Sanskritized version of Bengali. States with more than one national language may offer several versions of their anthem: For instance, Switzerland's anthem has different lyrics for each of the country's four official languages (French, German, Italian and Romansh). Canada's national anthem has different lyrics for both of the country's official languages (English and French), and on some occasions is sung with a mixture of stanzas taken from its French and English versions.National anthems are used in a wide array of contexts. Certain etiquette may be involved in the playing of a country's anthem. These usually involve military honours, standing up, removing headwear, etc. In diplomatic situations the rules may be very formal. There may also be royal anthems, presidential anthems, state anthems, etc. for special occasions.
