O Tannenbaum O Tannenbaum "" (; "O fir tree", English: "O Christmas Tree") is a German Christmas song. Based on a traditional folk song, it became associated with the traditional Christmas tree by the early 20th 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.

Anschütz based his text on a 16th-century Silesian
