English Christmas carol
"The Twelve Days of Christmas" is an English Christmas carol that enumerates in the manner of a cumulative song a series of increasingly grand gifts given on each of the twelve days of Christmas. The song, published in England in 1780 without music as a chant or rhyme, is thought to be French in origin. "The Twelve Days of Christmas" has a Roud Folk Song Index number of 68. The tunes of collected versions vary. The standard tune now associated with it is derived from a 1909 arrangement of a traditional folk melody by English composer Frederic Austin, who introduced the familiar prolongation of the verse "five gold rings".
