Silent Night was first performed on Christmas Eve 1818 in Oberndorf, Austria, with lyrics by Joseph Mohr and music by Franz Xaver Gruber. Originally written in German as Stille Nacht, it was translated into English in the nineteenth century and spread through churches, carol singers and recordings worldwide. Its simple, lullaby-like melody made it easy to arrange for piano, strings and music boxes. Today short excerpts circulate online as background music for seasonal videos, where the tune alone instantly signals Christmas without needing any lyrics or explanation.
