The Létourneau Opus 55 Organ
Mounted horizontally outside the case, the Trumpet en
chamade required thirty-seven hours of labor for its voicing in the
factory.

This instrument includes the first full-length metal 32-foot reed stop
built by Orgues Letourneau. (They have built four 32-foot metal reeds of
half-length.)
Forty artisans who worked on this instrument range in age from 18 to 64;
more than half have Letourneau organ building as their first and only
career.
On completion of First United Methodist Church's instrument in 2000,
Kalamazoo became the first city in the United States with two new organs
built entirely by Létourneau. Other cities with two or more already
exist in Australia, Alberta, New Brunswick, and Quebec.
Fewer than 3% of the total number of pipes are visible from the pews;
the others are behind the facade of the organ case. The 3,638 pipes constitute a small proportion of the roughly 100,000
wood, metal, and other components of the organ. Each large facade pipe required the efforts of two men a full day to
polish it.
The largest 24 pipes of the 32-foot reed and the largest 12 pipes of
all the sixteen-foot reeds have boots made of wood for endurance and
stability over the decades; the largest 12 pipes of all the sixteen-foot
metal ranks have double-thick metal in the foot to support the pipe's
weight in coming generations.

The most important "stop" on any organ is the room in which it is
placed; the last and most important 30% of pipe voicing is done on site
to fit the room's acoustics.
Opus numbers correspond to accepted design proposals, not contract or
completion dates. This organ, Opus 55, was finished in 1998; Opus 51 at
First United Methodist Church in Kalamazoo was installed in 2000, while
the four-manual Opus 50 at the University of Alberta in Edmonton was
completed in 2001.
Custom-designed, each organ is completely erected and playable in the
builder's shop before it is disassembled and shipped for installation.
After most parts were already made, erecting this organ in the shop took
four months; re-erecting it in the church took three weeks.
Pipes and other parts were transported from the shop to the church in
two fully packed 47-foot semi-trailers; three weeks later another
53-foot semi-trailer returned the empty crates to the shop.

Raw materials such as metal and wood used in the organ come from
Brazil, China, and the USA; stop-action parts come from Germany,
Maryland, and California.
The coloring of dark naturals and light sharps in the manual keyboards
follows historic tradition and affords best visual clarity in all types
of light.
The largest pipes weigh 450 pounds, the smallest less than a pencil.
The whole organ weighs about twelve tons.
This is the largest new organ built by Orgues Létourneau in this
century, although a university concert instrument nearly twice its size
was completed in 2001.
Létourneau employment has more than doubled within the past five years,
including 6-8 apprentices in various stages of training, but cannot keep
up with demand; current contracts will require three years to complete.
Letourneau has been selected to build new instruments in Oxford
University, the Tower of London, and Vienna.
