Carols at Christmas

Lisa Jardine reflects on the power of music to move, especially at Christmas, when the singing of carols unites singers and listeners alike, in an outpouring of community spirit. She also celebrates each advance in technology which has made music available to all, not just an elite, from the fifteenth century mass production of carol books to the screening in cinemas worldwide of opera live from the Met in New York.
