An Earth anthem is a celebratory song or a musical composition that eulogizes, extols or exalts the planet Earth.
History.
On the request of then United Nations Secretary-General, U Thant, a Hymn to the United Nations was performed on the occasion of its 26th anniversary, on October 24, 1971, by Pablo Casals, the lyrics to which were penned by the poet W.H. Auden. Thant first approached Casals, who was a personal friend, looking to create a hymn to peace and hoping for the song to be based on the preamble of the Charter of the United Nations. Thant later commissioned Auden to write the poem after Casals requested one to set to music. Auden completed his work in three days time. The finished work, scored for chorus and orchestra, takes approximately seven minutes to play. However, there were never any plans to adopt the song the organization's official anthem.
