The
Pedal Division
sits in the same chamber as the Great Division and more or less
surrouds it. There are 12 ranks in the Pedal Division.
Starting
with the smallest pipes in the Pedal Division are these four
ranks
of pipes. The left three ranks is the three rank Fourniture, a mixture
which was added in 1969. The rank of pipes on the right is an addition
to the existing two rank Scharf mixture. Like the mixture ranks in the
other divisions, these pipes add a
little bit of brilliance to a division dominated by low bass
pipes. |
 |
The
original two rank Pedal Mixture is in this picture on the left. Next to
the Mixture
are from left to right, Principal, Spitzprincipal (slightly tapered
pipes), Quinte and Posaune (narrow flared pipes). |
 |
The
Bourdon rank in
the Pedal Division is made up of wood pipes, unlike the Great Division
rank made of metal. In this photo the Bourdon pipes appear to be having
a conversation with the red felt topped Stopped Diapason rank in the
Great. |
 |
Most
of the big bass pipes in the Pedal are mounted against the wall in the
chamber. Opposite of the opening in the chamber is the Pedal Principal
rank (foreground), and the Great Principal rank (toward the end of the
pipes). Other than the Pedal rank being a little larger in diameter,
there is very little difference between the pipes of the two ranks. |
|
The
back wall of the chamber angles toward the stage as you get closer to
it. Mounted on the angle in the corner is the Quinte rank (visible),
and the Gemshorn rank behind it (not visible).

 |
As
we continue our journey around the perimeter of the chamber, we
encounter some of the larger pipes of the Pedal Bourdon rank. Behind it
are the largest pipes of the Pedal Principal rank. |
|
This
photo shows parts of several Pedal ranks. Wood pipes are the Bourdon,
behind it is the Principal rank. Just to the left of it are two pipes
from the Gemshorn rank, then next to it are pipes from the Quinte. On
the far left are a few pipes from the Posaune. All of the other pipes
belong to the Great Division. Note the plaster which has fallen off the
wall and into some of the pipes. The chamber needs some help!

The
biggest pipes in the organ are the bottom 12 pipes of the Posaune rank
which speak at the 32' pitch. These 12 pipes were added to the organ in
1969. The bottom three notes are on 10" of wind pressure with the other
nine pipes on 6" of wind. The rest of the rank is on 4 1/2" of
wind.
Their large
mitered construction and slightly flared ends make a statement in the
organ (as does their sound). The three bottom pipes are so heavy that
they require a wood brace seen in the two right photos. These pipes
also require a lot of air and sit on their own offset chest which is
seen in the bottom left photo. In the top left photo note the V-shaped
seam in the pipe's construction. |
