Robert Burns's 1788 poem “Auld Lang Syne” became the source of the lyrics for the song widely sung at New Year's celebrations. The Scots title means roughly “old long since” or “for old times' sake.”
Burns sent a version of the poem to the Scots Musical Museum, and the words were later paired with the familiar melody. The song reflects on friendship, shared memories and the passage of time, making it especially suited to a year-end farewell.
Although commonly treated as a Scottish song, “Auld Lang Syne” is now sung internationally. Its melody and verses can vary, and many people know only the opening lines and chorus. It is not exclusively a New Year's song, but that is its most famous modern setting.
