Toccata and Fugue in D Minor, J.S. Bach
This is the picture of the main part of the organ in the Cathedral of Passau. The organ consists of five separate parts – the great organ above the main entrance, the epistle and the gospel organ on the western gallery of the aisle, the choir organ at the altar and the echo organ in the attic behind the „Holy Spirit Hole“ in the ceiling in the middle of the nave. The organ‘s muted tones reach the interior through that hole in the ceiling. The largest pipe is more than 11 meters long and weighs 306 kilos. Its deepest tone is almost inaudible with a frequency of 16 Hz. The smallest pipes are 6 mm and their tones are almost to piercingly high for our hearing with a frequency of 16 000 Hz. More than 120 km cable had to be laid in the attic to connect the five organ parts. Your stereo speakers have 6" cone drivers?
It is the largest Cathedral Organ in the world.
