OK, so the divisions then are the labeled items in each of the sections:
http://en.wikipedia.org/wiki/Boardwalk_Hall_Auditorium_Organ
eg. Pedal Left, Unenclosed Chior, Great, etc ...
From a different organ:
http://en.wikipedia.org/wiki/Image:String-Division-Middle-Sect.jpg
Each row of pipes would be a rank, then?
So, the string division on this organ has dozens of stops?
OK. When you mentioned stops, you mentioned a 32' (or was it 16'?) stop.
Obviously from the sheer size a very low note. How does that relate to
the organ.
FWIW, you really can't appreciate a pipe organ unless you hear it live.
The church my inlaws go to has a pipe organ that they actually use. It's
pretty much brand new. The lowest notes were simply incredible to
experience. (It is a legitimate pipe organ, you can see the display
pipes, I have no idea where the rest of the instrument is. I've not
actually looked at the console.)

Yep. Learning to play a large pipe organ is like learning to drive a
car. You need both hands and your feet, and they need to work in a
coordinated fashion, but after a while you can do it with effortless
grace. (Depending on exactly what you're trying to do... F1 drivers make
taking corners at 160 MPH look pretty effortless, but *you* try it
sometime!)

Not entirely...
The divisions are a conceptual entity. Typical division names are
"peddle", "great", "swell", "choir" and "echo". Usually there is one
keyboard to each division. (But there can occasionally be "floating
divisions" that are only accessed by couplers.) Where the pipes
physically *are* in the building is an entirely different matter.
Pipes can be "enclosed", meaning they're inside a box with movable
shutters. A peddle on the console opens and closes the shutters, thus
altering the apparent loudness of the pipes. Apparently this organ has a
choir division where only some of the ranks are enclosed. (This is not
uncommon.)
The organ I played has *all* the pipes of the Swell enclosed, and *all*
the pipes of the Great and Peddle divisions unenclosed. (A completely
standard design for such a small organ.) At the end of the video you can
just about see me operating the Swell peddle, which opens and closes the
shutters.

Probably - but not necessarily. The organ builder can arrange the pipes
any way they damned well fancy. It *looks* like you're right, but it
might be that, say, each *pair* of rows is a complete rank, with the
pipes in one row being the next note up, or something.
> So, the string division on this organ has dozens of stops?
This is from the famous Wanamaker, the largest playable pipe organ in
the entire world. And yes, it is famed for its *vast* string division.
(The organ I played doesn't even have a single string stop. But then,
it's a *church* organ rather than a *theatre* organ.)
> OK. When you mentioned stops, you mentioned a 32' (or was it 16'?) stop.

A "normal" pipe rank is called an 8' rank. Because the lowest note has a
pipe roughly 8' long - assuming it's an open pipe. Stopped pipes are
half the length. And actually there are end corrections too depending on
the width of the pipe and other parameters... But notionally, 8' long.
Thus, any stop marked "8'" will cause the keys to sound at the same
pitch as a piano. (The organ I played just happens to have a piano sat
right next to it. Currently the church doesn't have an organist!)
A 4' rank sounds one octave higher, and a 2' rank sounds an octave
higher again. You can play such a rank on its own, or you can mix it
with a 8' to add more "brightness" to the sound.
In my recording, I have (from the looks of it) two 8' stops, a 4' stop
and the 2' pulled (in the Great division), and also a 16' in the Swell.
> FWIW, you really can't appreciate a pipe organ unless you hear it live.
No. My cheap camera mic doesn't do it justice. Why, you can hardly
*hear* the bass notes I'm playing! And they aren't even that low...

The peddle division on this organ makes the flower arrangements audibly
rattle.
Unfortunately, as I say, only some of the notes work. One of the peddles
just makes a hissing noise at you! o_O

To clarify: The organ I played has two 16' stops, and no 32' stops at all.
One of the 16' stops is obviously (the only rank in) the Peddle
division. The other one is in the Swell division, oddly enough...
Would you (or anybody else) be interested in a complete readout of the
organ stops?

Concave = the peddles in the middle are lower than the peddles at the
edges. The alternative is for all peddles to be the same height.
Straight = the peddles are parallel to each other. The alternative is
"radial", meaning the peddles radiate out around the stool.
> Peddle division:

Small organs typically have very few peddle stops. If there is only one,
it is almost always a Bordon.
> Great division:
> Open Diapason 8'
> Stopped Diapason 8'
These are your basic organ stops. Sounds rather flute-like. The stopped
diapason sounds quieter and more muffled, but otherwise similar to the
open diapason. These are both 8' (i.e., normal pitch) stops.
> Dulciana 8' (incomplete rank)
A rather pleasent, quiet stop, with a mellow tone. Sounds almost
"distant". It is "incomplete" in that there are no pipes for the bottom
octave.
> Principal 4'
> Flute 4' (incomplete rank)
> Fifteenth 2'
These sound more or less like diapasons, but higher-pitched. Use them on
their own, or mixed in with an 8' stop just to add more trebble.
> Swell division (enclosed):
> Double Diapason 16' (incomplete rank)
Double as in double length. (This is a 16' stop.)
> Horn Diapason 8' (incomplete rank)
I'm not fond of this one. Sounds a bit like a fog horn.
> Lieblich Gedact 8'
Ask Florian how the **** you pronounce that. (It seems to be roughly
"YEE-blihh deDAAkt".) It has a lovely flute-like tone, soft and
delicate. Works best for melodies rather than chords.
> Principal 4'
> Full Mixture III
Again, use these to flesh out the sound. Personally I don't like the
Mixture stop very much.
> Cornopean 8'
The only reed rank on the organ. (The others are all flue pipes.)
Produces an irritating trumpet-like sound.
> Tremelo (sic.)
Pull this and the organ makes a thunderous noise like an unbalanced
washing machine! o_O Makes all the ranks sound like they've been put
through a Leslie speaker. (It modulates the air pressure.)
> Couplers:

As demonstrated, this causes a second set of keys to move when you press
the first set. (Also makes the keys correspondingly heavier! And more
prone to jamming on this tired old organ.) On modern electric organs,
this would just make an extra rank speak without actually moving the
keys. I kinda like the graphic demonstration of what it does though!

Thanks for that :) an interesting read. So, this is a pretty typical
organ, then?

Heh. I'm glad somebody liked it. ;-)

It's fairly typical for a small Victorian organ, yes. The *exact* stop
readout varies according to the builder's taste and the time period, but
this is a fairly typical specimin.
2 manuals + 1 peddleboard is about the smallest pipe organs get. There
are smaller ones, but not often.
