The Great Fantasia and Fugue in G minor BWV 542 is an organ prelude and fugue by Johann Sebastian Bach. It acquired that name to distinguish it from the earlier Little Fugue in G minor which is shorter. This piece is not to be confused with the Prelude and Fugue in A minor which is also for organ and also sometimes called the Great.It was transcribed for piano by Franz Liszt as S.463.
