Sherborne Abbey - The Organ in the North Transept

SHERBORNE ABBEY

The Organ

The Abbey's magnificent pipe organ occupies a loft in the North Transept.  It was originally built in 1856 by Gray & Davidson to a specification similar to their exhibit at the Great Exhibition of 1851.  In 1951, it was rebuilt and had an electro-pneumatic action with a remote console installed by J W Walker & Sons.  Tonal adjustment was made by John Coulson of Bristol in 1971.  Unfortunately, the electro-pneumatic action did not stand the test of time and the instrument was completely rebuilt with a mechanical action by Bishop & Sons in 1986-87.  In 2004/5, the organ, once again, underwent a major improvement.  In the meantime, the Abbey was temporarily served by a superb electronic organ.

The 2004/5 rebuild by Mr Kenneth Tickell

When asked to inspect the organ in 2003, the brief from Ian Bell, the Organ Advisor to the Abbey, was: to address the problems of persistent murmurings and intractability of the actions, and to implement minor tonal changes, including returning the Choir organ back in the direction of its original roots. A new Nave organ was to be provided on the west wall of the Abbey, it now being realised that the poor position in the north transept had dogged the instrument since its installation in 1856. Our work has been comprehensive: the end result being effectively a new instrument within the carpenter case, and using the existing pipework. New slider soundboards have been made for each of the three manual divisions, the Bishop soundboards for the Pedal having been overhauled. There is a new console and mechanical coupling chassis, with new tracker action throughout the organ. The Pedal off-note chests had previously operated on a curious mixture of pneumatic and individual tracker actions. We have taken a pragmatic approach here, and, given the presence of electricity within the organ to operate the new Nave organ, have converted these to electro-pneumatic action, and also retained the optional electric assistance for the Swell couplers. The Nave organ can be played on either the Great or Choir keys. All the bellows have been releathered, and the original large double rise reservoir has been changed to two single rises on a common well, enabling the Choir organ to return to a more gentle pressure.

The pipework of the organ has been much reworked over the years in the course of the various rebuilds. There is still a core of  Gray & Davison work, particularly in the Great diapason chorus, and some of the flutes, and we have endeavoured to blend the new voices to these. On the Great there have been no significant changes, except to open up the Trumpet somewhat, and to create a difference between the two, previously similar, Open Diapasons, by cutting up and loudening number I while softening number II. All of the mixtures in the organ have been reconfigured with slightly lower breaks, and generally re-balanced. The Swell has gained new Flute 4, and also a Double Trumpet 16, allowing the former Contra Oboe 16 to return to a more useful 8ft pitch. The Cornopean and Clarion which had both been shortened and produced a very hard, cutting sound, have had extra pipes inserted to allow for a more blending tone created by longer resonators. On the Choir organ, the Clarabella, Principal and Flute have been retained, and the Cornet IV placed on a mounted block. A new tapered Gamba 8, Flageolet 2 and Mixture III join these ranks, while the former Clarinet has returned from its temporary sojourn as a Cremona . There are no changes to the Perdal organ.

Placing a Nave organ case in such a wonderful building has been a particular responsibility. The blank area of wall below the great west window was crying out for an organ case to be affixed to it, and there was just the right amount of height between the window and the west door for an 8ft case. The new pipework was made by Terry Shires of Leeds.  

Tonally, the new division has been a revalation. The main organ is extremely forceful at the console, and indeed in the opposite transept, but quickly loses vitality and power as one moves down the Nave. Adding one or two stops of the Nave section instantly brings an immediacy and presence into the main body of the building, which will be valuable for congregational accompaniment. The full chorus simply makes one realise how wonderful it would have been to build a new west end organ in such a building. Nevertheless, the slightly remote placement of the main organ does allow almost its full resources to be used in cathedral-style choral accompaniments, as was heard to good effect at the Easter services.

The work of Kenneth Tickell and his craftsmen has been comprehensive: the end result being effectively a new instrument within the Carpenter case, and using the existing pipework. New slider soundboards have been made for each of the three manual divisions, and the Bishop soundboards for the Pedal having been overhauled. There is a new console and mechanical coupling chassis, with new tracker action throughout the organ. The new Nave organ can be played on either the Great or Choir keys.
