Silent Night(Stille Nacht in German, Silens Nox in Latin) is perhaps the most beloved Christmas Carol. It was composed in 1818 by Franz Guber, an organist and schoolmaster, to lyrics by Father Joseph Mohr of the St. Nicholas parish in Oberndorf  bei Salzburg, Austria. It was first performed on Christmas Eve in 1818 and since the organ was broken, the only musical accompaniment was the guitar. The popularity of the song spread and the version commonly used today comes from a translation in 1859. John Freeman Young, serving as an Episcopal priest at Trinity Church in New York City, translated and changed the tempo of the song. The original rendition by Gruber was more like a dance tune and sung faster. Young made into a slower lullaby style that is the most common version today. Because it has been so widely translated, it is the one Christmas carol that is known worldwide.

In Austria Silent Night is not heard until Christmas Eve, usually around 9 p.m. Then it is played on the radio once an hour and of course during church services.
