Jingle Bells was written by James Pierpont in 1857, originally titled One Horse Open Sleigh, and it has since become one of the most recognisable Christmas songs in the world. Because the melody is in the public domain, it is widely recorded in many styles, including gentle music box arrangements like this one, which are popular for cards, adverts and online videos. The music box sound gives the familiar tune a softer, more intimate feel, which is why creators keep returning to it for holiday content year after year.
