Which song is traditionally sung at midnight on New Year's Eve in the United States?

Auld Lang Syne is traditionally sung at midnight on New Year's Eve in the United States.

The song uses a Scots poem attributed to Robert Burns, who wrote down a version in 1788. Its title means “old long since,” often understood as referring to times long past or old friendships. The melody and lyrics have appeared in several versions, so performances do not always use exactly the same words.

The song became strongly associated with New Year's celebrations in the United States during the twentieth century, helped by radio and later television broadcasts. Guy Lombardo and his Royal Canadians played it during their widely heard New Year's Eve programs, making the association especially familiar to American audiences.

Auld Lang Syne is not an official national anthem, and it is not exclusively an American tradition. It is also used in Scotland, Canada, parts of Asia, and other places for farewells, commemorations, graduations, and year-end gatherings. The Scots spelling and pronunciation may vary in international performances.
