A public service is a service which is provided by government to people living within its jurisdiction, either directly (through the public sector) or by financing private provision of services. The term is associated with a social consensus (usually expressed through democratic elections) that certain services should be available to all, regardless of income. Even where public services are neither publicly provided nor publicly financed, for social and political reasons they are usually subject to regulation going beyond that applying to most economic sectors. Public service is also a course that can be studied at a college and/or university.
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.
