There are many versions of this song. Perhaps you have never heard this version or verses. “O Christmas Tree” (originally known as “O Tannenbaum”) is a German Christmas song. “O Tannenbaum” (German: [oː ˈtanənbaʊm]; “O fir tree”, English: O Christmas Tree) is a German Christmas song. Based on a traditional folk song which was unrelated to Christmas, it became associated with the traditional Christmas tree by the middle of the 19th century and sung as a Christmas carol. The modern lyrics were written in 1824 by the Leipzig organist, teacher and composer Ernst Anschütz. A Tannenbaum is a fir tree. The lyrics do not actually refer to Christmas, or describe a decorated Christmas tree. Instead, they refer to the fir’s evergreen quality as a symbol of constancy and faithfulness. Anschütz based his text on a 16th-century Silesian folk song by Melchior Franck, “Ach Tannenbaum”. August Zarnack in 1819 wrote a tragic love song inspired by this folk song, taking the evergreen, “faithful” fir tree as contrasting with a faithless lover. The folk song first became associated with Christmas with Anschütz, who added two verses of his own to the first, traditional verse. The custom of the Christmas tree developed in the course of the 19th century, and the song came to be seen as a Christmas carol. Anschütz’s version still had treu (true, faithful) as the adjective describing the fir’s leaves (needles), harking back to the contrast to the faithless maiden of the folk song. This was changed to grün (green) at some point in the 20th century, after the song had come to be associated with Christmas.[2]it became associated with the traditional Christmas tree by the early 20th century and sung as a Christmas carol.
