The song traditionally sung at midnight in many English-speaking New Year's Eve celebrations is “Auld Lang Syne.”
The title is Scots for “old long since,” often understood in English as “for old times' sake.” The song's words are associated with Scottish poet Robert Burns, who sent a version of the lyrics to a friend in 1788. Burns noted that he had heard an older traditional song, so the modern text reflects both folk material and his writing.
The familiar melody became strongly associated with the song during the nineteenth century. Later, the tune and refrain spread internationally through Scottish communities, social clubs, radio, and public celebrations. The words ask whether old friendships and shared memories should be forgotten, making the song suitable for a moment of reflection.
People sometimes assume the song was written specifically for New Year's Eve. It was not: its lyrics and melody predate that association. It is also used at reunions, farewells, memorials, and other transitions, and performances often omit or repeat verses.
