At Christmas, we are especially touched by vocal music. Johann Sebastian Bach's Christmas Oratorio ensures sold-out churches for organizers. Last Christmas, Silent Night and Feliz Navidadare played over and over again in department stores. Choral music also provides a suitable musical setting for baking Christmas biscuits and wrapping presents. What is it that makes this music so appealing? Is it just the memories and traditions associated with it, or does the general atmosphere of Christmas songs already result in a radically different sound? Even in a secular world, Advent and Christmas maintain their central importance in the course of the year. The focus has evolved from the Christian celebration of the birth of Jesus to a festival of mutual affection.
