Buckfast Abbey, 

Devon, United Kingdom

The sound

Designing an organ presents many challenges, many of which are related to making the instrument fit tonally and visually into the building which will be its home. The challenges connected with our recent installation at Buckfast Abbey, Devon, England, were, in many ways, out of the ordinary. We were asked to design two instruments of considerable size, tonally interconnected, for a building of moderate size and very kind acoustics that amplify sound in a dreamlike fashion. While it was not difficult to design an instrument to play a variety of literature, much attention was required to scaling the sound to the building without sacrificing the proper characterization of the many different stops.

The tonal palette was based on an initial draft by Matthew Martin, international recitalist, former organist at the London Oratory and now Fellow and Director of Music and College Lecturer at Keble College, Oxford. Further adjustments were coordinated between Philip Arkwright, Organist and Master of the Music at Buckfast Abbey, and Fratelli Ruffatti.

The main instrument, of four manuals and pedal, is located on two sides behind the choir stalls and partially on the triforium level (the upper arcaded gallery) above. Specifically, Great, Positivo (in the Italian style, hence the name), Swell, and Pedal are housed inside solid oak cases at nave level, while the Solo division is placed at triforium level, along with a whole series of “special effects” playable from the Positivo, some of which belong to the early Italian tradition.

The second instrument, comprising two manual divisions with full pedal, is located in the west gallery and partially in the triforium level areas that are closest to the west gallery. Two nearly identical four-manual consoles have been provided, one in each location. The difference between the two is that the Quire console is equipped with an electric lift that adjusts the height of the keydesk and stop jambs by more than four inches (10 centimeters). This feature, along with the two height-adjustable benches (one for concert use, and one for teaching purposes), makes it very easy for any organist to find comfortable playing space. 

As G. Donald Harrison, the Englishman who became tonal director of Aeolian Skinner, once stated, “To me, all art is international; one can draw from the best of all countries. I have used the technique at my disposal to produce instruments which I consider suitable for expressing the best in organ literature.” This instrument indeed embraces this philosophy. The requirements for the seven initial worldwide organbuilders that were asked to submit specifications included the need for the instrument to support a wide repertoire of accompanied music, as well as to successfully perform a wide range of organ literature. Such requirements were not taken lightly and, drawing from decades of experience and from different traditions, as Harrison advocated, Ruffatti introduced several tonal features that are new or rare to find in England, with the aim of sparking interest for improvisation and creative registration for the international repertoire. 

It is along these lines that the Gallery Organ was designed. It draws from the French Romantic tradition of Cavaillé-Coll. Dedicated studies were conducted on several organs in Paris and other locations in order to ensure as close a proximity as possible to the Cavaillé-Coll style, by carefully copying pipe measurements and voicing methods, without pretentious claims of authenticity. The instrument is designed as a two-manual, but it can also be used as a large cohesive division, part of which is under expression, that can be played against, or in tandem with, the main Quire Organ. 

Along the same line of thought, the Italian Positivo was introduced in the Quire. With the tonal consistency of an early Italian instrument and the trademark low-pressure voicing, it provides all tonal resources needed to faithfully perform classical Italian literature from the Renaissance up to the early Romantic period, an ingredient that is indeed rare to find in an instrument in England. It is also ideal for playing in alternatim with the monastic choir. This is not just a nice “toy” to have, but serves convincingly as a Positiv division, in dialogue with the Great for access to a broader classical repertoire.

Another note of interest concerns the Solo division, which includes stops that have been drawn from the Skinner tradition, as well as other orchestral stops of Ruffatti design.

One of the aspects characteristic of Fratelli Ruffatti is that we manufacture almost everything in house, including flue and reed pipes. This is the best guarantee for quality control. At the same time, it provides the opportunity to carefully select all the ingredients that are necessary in the mind of the tonal designer. The difference is in the details. Being able to pass any requirements that experience dictates on to the pipe shop enables the voicers to exactly tailor the sound to the room, resulting in that perfect blend for which Ruffatti is famous.  

Versatility is only partially the product of having a variety of stops on hand; what really makes the difference is the ability of each stop to combine successfully with all others to produce countless tonal combinations. Open-toe voicing for principals and flutes is the key, as it favors blending of sounds, as well as promptness and precision of speech, an aspect that is of paramount importance, especially when there is no close proximity of the player to the pipes (as there would be with a mechanical action instrument). An old misconception still flies around, deriving from the early neo-Baroque times of the Orgelbewegung, or Organ Reform Movement of the mid-twentieth century, where the open-toe voicing technique was sometimes used to produce excessively harsh sounds. Open-toe voicing is instead quite versatile, ideal for the effective voicing of a rank of pipes in a variety of styles, regardless of the chosen wind pressures. 

Materials for the construction of pipes include the ultra-shiny alloy of ninety-five percent tin, used for the pipes in the façade as well as for a high number of larger internal pipes. Its structural strength and incredible resonance properties make it ideal for pipes of larger size. Other internal pipes are made with a tin percentage ranging from 75 to 30 percent.

Many pipes are made of wood, including the resonators of the two majestic 32′ reeds, the Bombarde, and the Fagott. Only the finest African Sipo mahogany has been used, varnished inside and out to enhance resonance. The Pontifical Trumpet, which projects horizontally from the front of the Gallery Organ, has highly polished solid brass resonators.

This organ was featured in the press for the first time in the March 2018 issue of the British magazine Organists’ Review with an article by Philip Arkwright, Organist and Master of the Music at Buckfast Abbey. It was inaugurated on April 20, 2018, with a splendid concert performed by Martin Baker, Organist and Master of Music at Westminster Cathedral, which I had the good fortune to witness. The improvisation that closed the performance was stunning: a perfect demonstration of creativity and a kaleidoscopic use of musical color.

The opening organ series also includes concerts by Vincent Dubois, titular organist of Notre Dame Cathedral, Paris; David Briggs, Artist-in-Residence at St. John the Divine, New York City; Matthew Martin, Director of Music at Keble College, Oxford; Richard Lester, international recitalist; and in-house organists Richard Lea and Matthew Searles.

Architecture and technical features

The east and west organs at Buckfast Abbey are aesthetically quite different. The east organ (Quire) is intended to be discreet, as the client’s desire was that the front of the building should not have the imposing presence of an intricate organ design. For this reason we chose a very simple layout for the façade, with pipes recessed into three arches that crown the stalls on both sides of the Quire. The pipes are hardly visible from the center of the building, but clearly show the brightness of the tin they are built from when they are seen from the side.

The central pipe of each bay, with its diamond-shaped embossing, reflects the light in all directions, providing a touch of richness within the simplicity of the design scheme.

The west organ (Gallery) gave us the opportunity to offer a more sophisticated architectural solution. The full visibility of the splendid stained glass windows being paramount, we built two symmetrical oak organ cases against the side walls of the gallery, with tunnels to grant access to the balcony from the doors in the back corners. The aim was for a design of lightness and richness at the same time—not an easy task, as the two qualities are normally in conflict.

To achieve this goal, we chose a case design where the façade pipes are not topped by a ceiling. Instead, there is an alternation between bays having pipes with unobstructed tops and pipes with carved elements defining the top line. The richness is provided by the carving, which is also used to separate façade pipes within the same bay. In the general scheme, it gives visual continuity to the various bays. These elements have been hand-carved from European oak by a gifted artist, from a Ruffatti design inspired by the intricate and elaborate carved wood of the Abbey’s choir stalls. Even the panels of the lower part of the case are enriched by carvings in the Gothic style. 

The sunlight coming through the stained glass windows is reflected by the shiny surface of the tin pipes, adding a touch of color to the façade, an effect that is remarkably spectacular.

The signature Ruffatti horizontal trumpets, with their flared brass bells, extend from the lower part of the cases, projecting their shining beauty into the Abbey’s central bay.

The most frequent comment we have received on the design is that the organ looks like it has always been there. I believe that this is the biggest compliment that can be paid to the designer, because it proves that the organ belongs to the building, without imposing its presence. The initial aim has been reached: a light yet elegant result.

On the strictly technical side, African Sipo mahogany is widely used for functional parts, such as all of the windchests. The main units are of the slider type, which are controlled by solenoids of the latest generation, featuring self-adjusting power for the initial stiffness of the slider movement and reduced power at the end of the travel, for maximum silence.

The twin consoles feature identical controls and can be played simultaneously, as they often are. The control system is operated by the organist from a touch-screen panel, and it offers a large number of functions. The huge memory provides separate password-protected storage folders for many organists, where stop combinations, personal crescendo, and tutti settings can be stored. The system also features, among many other useful tools, a transposer, a record/playback function, and on-board diagnostics, a useful tool for maintenance.

The height adjustment of the keydesk of the Quire console is controlled by a push button, operating a heavy-duty electric motor. Adjusting the level of the keydesk allows maximum comfort for the player, regardless of that person’s physical height and build.

The organ is distributed over several locations and, true to Ruffatti philosophy, uses several different wind pressures to optimize the tonal result of the various stops. As a result, nine separate blowers, twenty traditional reservoirs, and nine schwimmers have been used to provide adequate and stable wind at the many different pressures, ranging from 40 to 185 mm.
