A. David Moore, North Pomfret, Vermont, Opus 27
The home of George Becker and Christo Bresnahan,
San Francisco, California
From the builder
Opus 27 is a compact two-manual organ designed to give the player the
greatest number of stop combinations and colors from a small stoplist. The
lower keyboard controls the Great, the upper the Positive. The manual compass
is 56 notes, and the straight pedalboard has 30 notes. Couplers include
Positive to Great, Positive to Pedal, Great to Pedal. The tremulant affects the
entire organ.
The Great has an 8' Clarabella, a 4' Principal in the display, Twelfth,
Fifteenth and Seventeenth. The Clarabella is scaled after examples found on
early Hook organs. The bass octave is stopped. Pipes from tenor C are of open
wood and of English style construction with the windway carved into the cap.
They are similar to early New England-style Stopped Diapason pipes without the
stopper. The blocks have a little step down after the front edge next to the
windway, which helps a great deal with the speech of the pipes. Provision of an
8' open stop on the Great allows for a rich plenum with a strong fundamental.
The Clarabella, drawn alone, serves as a distinctive foil to the 8' Stopped
Diapason. The Clarabella must not be confused with the Melodia, also an open 8'
stop. (The Melodia typically has an inverted mouth, a cap that protrudes over
the front of the pipe, more nicks, and a block, the top of which is curved
forward in various degrees depending on the builder.) Twenty-one Principal
pipes are in the display above the keyboards. The treble pipes are in the case,
followed, front to back, by Fifteenth, Twelfth and Seventeenth. Initially
conceived as a double draw Sesquialtera, it was thought better to separate the
two ranks to allow greater freedom of registration.
The Positive has an 8' Stopped Diapason of wood, a 4' Flute and an 8'
Trumpet. The Stopped Diapason is quite literally an open wood diapason which is
stopped, in the manner of early Hook and English examples. The speech has a
hint of quint and a subtle chiff. The Flute is of open wood pipes. The bass of
the Trumpet has wooden resonators, wooden blocks and shallots.
style="mso-spacerun: yes"> The blocks and shallots are turned (on
a South Bend lathe) from a single piece of wood. The inside bore of the shallot
is tapered. The tongue is held in place with a hardwood cleat and two small
wood screws. The opening in the shallot is tapered and milled into the wooden
face. The dimensions of shallot opening, bore, taper and resonator inside
diameters are close to eighteenth-century North European practice. The use of
wood for the shallot avoids the need for lead-faced shallots or leathered
shallot faces. The wood face, in terms of hardness, is somewhere between lead
or brass and a leathered surface. The brass tongues are fairly wide, thick, and
tapered. The lowest octave has wooden resonators which impart a strong
fundamental and circumvent concerns about collapse. Metal resonators are used
from 4' C with wood shallot-blocks; at middle C the resonators are metal, the
blocks lead and the shallots brass, much like an old North European Trumpet.
The Trumpet has a brightness of speech as well as a distinct and prominent
fundamental throughout. The Trumpet can be played either from the upper manual
or from the pedal, or on both manuals and pedal simultaneously. It is useful
for a cantus firmus, or for an independent pedal line when used with the 8' and
4' Positive stops against the lower manual plenum, and is satisfying as a solo
register.
The Pedal contains the 16' Subbass of butternut wood; the lowest six pipes
flank the manuals. The butternut, like most of the wood in the organ, was
felled on the North Pomfret Moore property. The logs were sawed into boards of
various thicknesses on a WoodMizer thin-kerf band sawmill. Much of the wood is
quarter sawn.
Metal in the Principal is lead with 28% tin. Smaller amounts of antimony,
bismuth and copper are added to the metal alloy. The melting pot holds 700 lbs
of metal. To this is added 1.25 lbs of antimony, .25 lbs of bismuth and 2.5 lbs
of copper. Copper seems to give the alloy a nice ringing sound. Antimony is
added to prevent metal collapse. Pipe metal was poured, hammered and fashioned
into pipes all in the Moore workshop. (A Dom Bédos-type hammering
machine, made by Dave Moore, graces the workshop and is used "once in a
while.") A new hammering machine that can automatically hammer a full
sheet of metal as it is taken from the casting table is now used. This machine
has 17 metal hammers that are raised and dropped onto the metal all at once,
covering the whole width of the sheet. The sheet is then advanced a fraction of
an inch and the hammers move over slightly. Metal hammered with this machine
prevents the "bacon effect" (caused by sheets of metal being hammered
on the edges more than in the middle, thus the sheet starts to get wavy like a
piece of cooked bacon). Hammering pipe metal is an old practice that hardens
the metal, optimizes pipe resonance and imparts a richness of timbre not
otherwise obtainable.
The metal pipework is voiced with fairly wide windways and regulation at the
toe hole for most stops. The toe holes are closed down until the volume of the
pipe is just right. In essence, an Open Diapason register would have pretty
much open toes in the mid range and then the treble pipes would be regulated a
bit at the top register. Toe regulation is important in stops above 4' pitch.
Thus with a 2' stop the windways are kept just right in the top octaves and the
volume is controlled at the toe. This keeps the top ranges of the stop from
being too loud and overpowering. This style of voicing, with moderate nicking,
is just about what the early New England organ builders practiced. One can
often find this type of voicing in various European styles. The pipes are cone
tuned.
The action is suspended, and is provided with easily accessible adjustment
nuts. Trackers are of wood with rolled threaded brass ends and wood or leather
nuts for adjustments. Some tracker ends have wires into the wooden trackers
that go through unbushed metal rollerboard arms. The pedal action has some felt
bushings and washers but the manual keyboards do not.
Winding for the organ is controlled by a small curtain valve. A small
single-fold reservoir is located at the bottom inside the case and feeds air to
three windchests through solid wood trunks in the manner of old instruments.
Pressure is 211/16 inches. Winding is flexible in that a sustained note in one
part of the keyboard is influenced by a moving passage in another part of the
register. The blower is a quiet operating Laukhuff. The tremulant is of the
tremblant doux type described by Dom Bédos and found on early French and
New England organs. A leather-covered door is poised at an angle in a horizontal
section of the main wind trunk. When the tremulant is engaged, the door
oscillates back and forth, creating fluctuation in the wind pressure and a
tremulant effect that varies depending on what is being played.

From the owner
I first met Dave Moore in 1970 when he was renting an apartment in the
Pigeon Cove house of Charlie and Ann Fisk. David apprenticed in the then small
Fisk shop before establishing his own workshop in North Pomfret, Vermont, where
he has been designing and building historically informed mechanical action
organs for over three decades. This unique builder has traveled extensively and
studied some of the finest old (and some new) organs of Germany, France, the
Netherlands, Denmark, Italy and England. He has a working knowledge of the
treatises of Clicquot and Dom Bédos. Living and working in New England,
he has acquired a knowledge, both intimate and scholarly, of the 18th- and
19th-century New England builders. His association with the likes of John Fesperman,
Barbara Owen, Fenner Douglass, Mark Brombaugh and Kevin Birch (to name but a
few) has contributed to his understanding of the organ and its music. (Indeed,
David himself is a quite respectable organist.)
Opus 27 was built almost entirely from trees harvested by David Moore on his
Vermont farm, from lead and tin melted, poured and hammered, and from cow
bones, fashioned into keys and stop labels, all in his workshop. When I visited
the shop in 2000 to see the progress of the instrument, boards for the Subbass
still had bark on them! Wood in the organ includes butternut, black cherry,
maple, ash, walnut, pine and oak. Basswood is used for the tableboards of the
windchests. Sliders are made of poplar. Pipe shades were designed by Tom Bowen
and carved by Dave Laro.
Working out the stoplist was an exciting process involving frequent e-mails,
conversations and a number of changes. The goal was to create an instrument of
character (Moore character) with a light, responsive suspended action, stops of
distinctive color, resilient winding, and a case which bespeaks its New England
roots.
Dave Moore and Thad Stamps drove the organ from North Pomfret to San
Francisco in 72 hours! Christo and I helped them unload pipetrays, blower and
organ parts into the modestly sized music room of our San Francisco Victorian.
Over the next three weeks the organ was erected and Dave completed tonal
finishing. The organ has an unmistakable character reflecting David's vision,
his New England craftsmanship and his musical genius. Opus 27 was celebrated
with a dedication recital played in January 2003 by Charles Krigbaum. At that
time Dave Moore gave a brief demonstration of the organ to an appreciative
audience.
Dave Moore prefers to avoid the term eclectic for his organs:
. . . the organs I've made have
a certain sound to them. Pretty full, quite a lot of fundamental, good solid
bass to most things, upperwork designed along the lines of early American
organs . . . I prefer not to have them labeled in any one way. If you say,
"This is an organ constructed after French principles," some people
think that all you can play on it is French music. I prefer to keep the stop
nomenclature in English, so that if someone comes along and says, "Aha!
This is very much like the old Dutch organs, it's perfect for that," they
play that music on it and they're very happy . . . You're much better off if
you can accept an instrument for what it is and play what you can on it.1
Although I have found the organ especially appropriate for playing Bach,
Sweelinck and their contemporaries (having myself played many old organs of
Holland and North and Central Germany), opus 27 does admirably well with the
likes of Franck, Hindemith, Pinkham and Hampton. David Moore and his co-workers
Tom Bowen and Thaddeus Stamps have created a cohesive, harmonious and
imminently musical organ in a little shop in rural Vermont. The sheer joy of
playing this splendid and modestly elegant instrument is, for me, as good as it
gets.

Fabry, Inc., Fox Lake, Illinois, has
completed the renovation of the organ at Zion Lutheran Church, Marengo,
Illinois, originally built in 1960 by Haase Pipe Organs of Chicago as three
manuals and 40 ranks. In 1986 the congregation demolished their old church and
built a new one on the same site. The organ was dismantled, stored, and then
installed in the new building. Over time, the organ deteriorated to the point
where some major work was necessary.
In February 2002, Fabry was engaged to repair, refurbish, and enlarge the
organ. Phase one, completed in October 2002, included a new three-manual
console with movable platform built by Fabry. The new console was fitted with a
Peterson MSP-1000 combination action, multiplex coupler relay and chamber
relay, and is prepared for MIDI. Phase two, completed in February 2003,
included the addition of six ranks of pipework, several additional windchests,
four new wind supply reservoirs, four electric tremolos, a Zimbelstern, and
complete revoicing and re-regulation of the entire instrument. Some of the
existing pipework was repaired and re-racked, and one rank was relocated. David
G. Fabry built all the chestwork, three-manual console, and movable platform.
Joseph Poland handled the installation.

Bedient Pipe Organ Company
Roca, Nebraska
First Presbyterian Church
Chippewa Falls, Wisconsin
The challenge to Bedient was to maintain the integral parts of an 1889
Steere and Turner, update and expand the organ, while at the same time make the
organ user-friendly and accessible. Opus 72 at First Presbyterian Church,
Chippewa Falls, Wisconsin (II/30) accomplished just that. In 2003, much of the
organ was dismantled and moved to our Lincoln, Nebraska shop where it was
reassembled, and old and new were interlaced.
New additions to the organ are 11 ranks of pipes (including a new speaking
façade drawn from the Principal 8' and Pedal Principal 8'), a new,
enlarged Swell windchest, electro-pneumatic stop action, solid-state
combination action, electro-pneumatic Pedal key action, wind system components,
both keyboards, the pedalboard and an adjustable height organ bench. Retained
and modified were the Great windchest and Pedal Bourdon wind-chest, some of the
façade casework (necessitating the stripping of old paint and careful
matching of cherry wood finish on both old and new parts), and structural parts
of the organ. The entire organ was revoiced to accommodate the newly renovated
sanctuary and blend the old and new pipes to be as one. The new stops are
indicated in italics.
