Nice story in the New York Times - replica of an unplayable historic organ at Vilnius built in Rochester NY
some excerpts
The organ, the Craighead-Saunders, is a unique instrument, not only because of its lovely sound, but also because it is a nearly exact copy of a late Baroque organ built by Adam Gottlob Casparini of East Prussia in 1776. The original stands in the Holy Ghost Church in Vilnius, Lithuania.
The project to build a replica of the Vilnius organ began in 2000 at the Eastman School of Music at the University of Rochester, but Eastman had long wanted a new instrument for Christ Church. David Higgs, a concert organist and head of the Eastman organ department, had been seeking one for years.
In 1998, Mr. Higgs met Dr. Davidsson, the founder of the Goteborg Organ Art Center in Sweden. The center specializes in reconstructing historic organs and in making sure that restored instruments sounded the way the builders intended and that they properly played the music that was written for them.
Reconstruction is not easy. The technique for building large Baroque pipe organs had matured by the 17th century, but progress since then has put new tools in builders’ hands. Entirely new schools of organ-building, performance, composition and taste evolved. These days, organs are tuned differently. Many are bigger, more robust and designed to play different kinds of music. Older organs needed to keep up with the times, so they were modified, sometimes so radically that their original tone could no longer be discerned.
It took four years to make the parts in Goteborg. Meanwhile, in Rochester, specialty cabinet-makers were building a new organ balcony for Christ Church, using lumber salvaged from a 19th-century South Carolina factory. Digital scans enabled the team to reproduce the carvings of the Vilnius cabinet, including the statue of King David above the console. German specialists painted the exterior wood surfaces with 18th-century-style gesso.
The Goteborg Center formed a collaboration with the Lithuanian Ministry of Culture and Mr. Gucas to support Lithuania’s efforts to restore the Vilnius organ and make a replica as part of the project.
The team began by measuring everything in the Vilnius organ, including the cabinets and the smallest hand-wrought iron fixtures and nails. Team members made drawings of every fixture, every join, every pipe and every surface. The data were printed out and put together in enormous manuals the size of telephone books.
Then they were analyzed. The team removed the pipes to study the metal composition and to test the acoustics. The Vilnius organ was not playable, so the team could not hear what it sounded like. In fact, the meticulous preparations were necessary partly because the replica was to provide guidance in restoring the original.
The organ arrived in Rochester in 2007 and took a year to assemble. Behind the soaring facade, the interior is roomy and airy like a three-story, walk-in pine closet. Pipes of all sizes leap toward the rafters, but virtually all the moving parts — stop throttles, key action, air valves and trackers — are made of wood and driven mechanically by the power of human hands and feet.
The organ made its debut in October 2008, with four days of lectures, workshops and concerts.
