The Swell Division pipework sits inside the left organ chamber (right side if looking toward the rear of the church). The Swell generally has softer sounding pipes which are commonly used to accompany choral singing. There are 16 ranks with 1,000 pipes in the Swell. |

A good bit of the pipework in the Swell is visible here. Next to the walkway is the four rank Plein Jeu which is another type of mixture stop producing a different sound. Behind it are the Tierce, Blockflöte, Nazard, Harmonic Flute, Octave, Viole, Viole Celeste and Principal ranks. From a distance these pipes all look the same but subtle variations in their construction result in different tonal sounds. The wood pipes are from the Bourdon rank. The stops in the top of the pipes double the speaking pitch of the pipe, therefore an 8' long pipe will speak at the 16' pitch. |

Here's a
closer look at the mitered pipes on this side of the chamber. The
wood pipes are also present in this picture when the pipes were still
in the shop. |

One of the more unique ranks in the organ is the Harmonic Flute. These pipes are constructed twice the normal speaking length then overblown to speak at the octave or intended pitch (an example of overblown is when a kid blows too hard into a recorder causing it to screech). The holes prevent it from speaking incorrectly and give it a distinct spotting feature. Click on this link to get a more technical description. |

Along the back wall of the chamber are the three reed ranks: Clarion, Trompette and Hautbois. The ladder on the right is the access to the Pontifical Trumpet pipes. |
 |
Here's a closer look at the reed ranks. The ranks are from left to right Clarion, Trompette and Hautbois. The Clarion is sometimes considered to be a higher pitched Trompette rank. The Hautbois is also sometimes called an Oboe and has a slightly rounder tone than the Trompette or Clarion. |
