The song traditionally sung at midnight on New Year's Eve in many English-speaking countries is “Auld Lang Syne.”
The title is Scots for “old long since,” a phrase referring to former times, memories, and old friendships. Scottish poet Robert Burns sent a version of the words to a friend in 1788, noting that the song was based partly on older material. The familiar melody was paired with the lyrics in later musical tradition.
“Auld Lang Syne” became closely associated with New Year's celebrations through Scottish Hogmanay customs and the spread of Scottish communities around the world. It is also used at farewells, reunions, memorials, and other transitions.
The song is often misunderstood as a specifically British national anthem or as a song written entirely by Burns. Burns preserved and reshaped traditional lines rather than creating every element from scratch. Its reflective theme explains why it fits a celebration that looks both backward and forward.
