A national anthem is a patriotic musical composition that represents a country. It is often played during official events, ceremonies, and celebrations, serving to evoke national pride and unity among citizens. National anthems typically include lyrics that reflect the history, values, and aspirations of the nation. Most countries have their own unique national anthem, which may be sung or played at various occasions, such as sports events or national holidays. The United States has "The Star-Spangled Banner," while France is known for "La Marseillaise." These anthems are important symbols of national identity and heritage.
