Prelude and Fugue in C minor, BWV.546

Prelude and Fugue in C minor, BWV 546, is a piece of organ music written by Johann Sebastian Bach, with the prelude dating around his time in Leipzig (1723–1750), and the fugue dating around his time in Weimar (1708–1717). Like most other organ prelude and fugues of Bach, no autograph score survives, with the oldest known score copied by Johann Peter Kellner, an acquaintance of Bach. The work was played as a postlude for the funeral of Diana, Princess of Wales, the funeral of Prince Philip, Duke of Edinburgh, and the Committal of Queen Elizabeth II by organists Martin Neary and Luke Bond, respectively.
