IMPROVISATION BY BILL SIBBEY ON THE BEVINGTON ORGAN O WORSHIP THE KING (Hanover)

The firm of Henry Bevington built a large four manual organ for the Church of St Martin's-in-the-Fields in 1854. An inscription on the St Mary's console states that they were Medal Winners in London (1862) and Paris (1855 and 1867). The late Austin Niland once said that he considered that the Diapason Chorus at St Mary's was one of the finest in the area, but this was before work was done on the organ in 1965.

The organ was installed and playing at the opening of the new St Mary's Church on 15th October 1878

In 1904 four speaking stops were added to the Swell Organ, namely a soft (very!) Salicional and, on a separate added soundboard, Contra Fagotto, Vox Humana and Voix Celestes. At the same time the Swell also acquired its Octave coupler.   It is hoped that in the very near future a more suitable pair of Swell strings will be inserted, replacing the Salicional and Voix Celestes, from a Bevington organ which has been removed from a church, but which is contemporary with the St Mary’s instrument.

In 1965 the firm of Cedric Arnold, Williamson & Hyatt were employed to do some work on the organ and removed (unfortunately) the Double Diapason 16' rank from the Swell. The unique to Bevington's Swell Double Diapasons were of exceptional quality - from middle C upwards the rank had full length metal open diapason pipes. The pipes below middle C were exquisitely voiced stopped wooden pipes and the join tonally between the metal and wood pipes was seamless. The bottom octave's pipes were outside the swell box. The original Pedal Bourdon was renamed "Subbass" and a second-hand Bourdon rank (which appears to be Bevington pipework) was placed on a 'Roosevelt' electric action chest and from it the Acoustic Bass 32', the Bass Flute 8' and Flute Bass 4' are derived. This rank is also found on the Great manual as Bourdon 16'. The remaining Pedal stops are on electro-pneumatic action. A modern radiating/concave pedal board and a balanced swell pedal were also installed at that time and the chorus reeds were revoiced, but I feel that this was not a successful venture, as they seemed to lose some of their original "fire"

A glance at the specification of the instrument below will bring to your notice two electronic additions to the Pedal Organ, namely Trombone 16' and Contra Trombone 32'. David Houlgate, who installed these two stops in 1980, is a well-respected electronic organ engineer in the South East of England, who installed the superb theatre organ in Portslade Town Hall, near Brighton, which he co-owns with Michael Maine - often heard playing it on "The Organist Entertains" on BBC Radio 2. The sound of these electronically generated stops is relayed through a tall bank of six 15" speakers situated at the back of the organ. Much adjustment has been made to the volume and timbre of the sound reaching the listener (we have got it spot on now - a slightly 'rounder' version of the Great Trumpet) and when used with full organ combinations with reeds, the effect is very convincing - helped of course by the generous acoustics of the building - and (I know this sort of thing has been said many times) to anyone listening in the body of the church it is extremely difficult to tell the difference between these additions and the real thing - if not in the know, they are none the wiser. The fact that we have these 'luxury stops' will probably upset the die-hard purists, but even I, who tend to lie in that particular camp, would hate to have to part with this unit. It completes the "full organ" ensemble in a thrilling way that can only be obtained by the use of pedal reeds, hitherto unavailable here at St. Mary's. David has been commissioned to install a replacement 32' electronic Open Wood on the famous organ of the Dome, Brighton (to replace the original device, installed in 1936, when electronics were still in their infancy, which is now "kaput!")

It was in 1997 that we at St Mary's had to face the fact that an instrument over one hundred years old cannot go on for ever without something wearing out. The springs inside the Bourdon chest were rusting and breaking (causing cyphers) and these have been replaced. The Swell stops marked * in the Specification below stand on a pneumatic soundboard worked from the main Swell soundboard. The pneumatic motors were all re-leathered as they were drying out and therefore did not 'flex' as they should, causing sluggish speech of the pipes, also some leathers were splitting. The hitherto uneven speech of the Bell Diapason has now been corrected and many damaged pipes caused by decades of cone tuning were repaired. The tuning stoppers of many of the stopped wooden pipes in the instrument have been replaced or re-packed as necessary. The coupling mechanisms (Swell Octave coupler and manual to manual and manual to Pedal couplers) have been completely reset as some of the keys were getting very hard to depress and also, because the mechanism was out of adjustment, some of the notes were not coupling through properly. The last task, and the most difficult one to be done, was to completely replace the leather of the main wind reservoir, as it had begun to leak badly owing to the fact that the original material was perishing.

But now to the all important tonal matters …........

It appears that, some years ago, (1965) the wind pressure was raised to three inches w.p.g. to make the organ sound more forceful. This meant that the pipes were being overblown and the Diapasons especially were 'hooting' rather than 'singing', the Great upperwork was 'spiky' and harsh (obliterating the Trumpet somewhat), the Great Claribel had a hard tone and, in my opinion, was rather characterless, and the Bell Diapason and the Swell strings had a nasty 'edge' to the tone. The Choir Leiblich Gedackt had an annoying transient hoot (rather like a 'coughing bourdon'). John and Eric Shepherd of Edgware (whose expertise with restoring old organs is renowned), visited the church with the Organ Club in the early 1990's, and thought then that the instrument sounded odd, and weren't too impressed. (They have recently been back and have voiced their praise of the organ as it sounds now). It all came to light when Patrick Christian experimentally removed some weights from the bellows on one of this tuning visits (he had his suspicions that the pipes were being overblown) and after replacing them left a note in the tuner's book to the effect that without them the organ certainly sounded better (especially the Diapasons). So, one of our plans was to incorporate the lowering of the wind pressure in the context of the work to be done on the organ's overhaul. But, anything proposed has to be passed by that body of church bureaucracy known as the Diocesan Arts Committee (the DAC), the dishers-out of those bits of paper known as "Faculties". All of the remedial work to be done was "OK'd", but with the proviso that we should get in an independent expert to asses the validity of our concern about lowering the wind pressure.

Well, Alan Thurlow of Chichester Cathedral, who was sitting on the DAC (and no mean Organ Adviser himself) recommended that we call in the eminent authority, Dr Nicholas Thistlethwaite, the author of the book, "The Making of the Victorian Organ". As our organ was built in that era, Nicholas was keen to come and test it out and he visited us in late November, 1997, in the presence of Pat Christian, Stanley Houlgate (Organist & Choirmaster) and myself. After he had played through all of the individual stops and ensembles on the instrument he agreed that "Summat was certainly wrong". In his subsequent letter to us, he said .......

"It was a great pleasure to have the privilege of hearing and playing your splendid organ. It is by any standards a fine musical instrument - a rare and important example of Bevington's work from the mid-Victorian years. During my visit a number of weights were removed from the bellows in order to lighten the pressure and the musical change was striking. Previously, individual registers had sounded forced and 'edgy' and spoke too quickly, giving rise to an unpleasant speech characteristic (a sort of 'plop', for want of a better word). Although the 'chorus' effects sounded impressive, the pipework was not speaking with natural ease. However, with the pressure lowered, it regained the unforced musical speech I would expect to find in an instrument of this vintage and provenance, and the reeds lost some of their blandness. I am therefore happy to endorse the proposal to reduced the wind pressure and which will enhance (or perhaps I should say, restore) the organ's intrinsic musical character"

Soon after Nicholas's visit to us, Patrick and I experimented with different wind pressures - this entailed humping cast iron slabs of different weights on and off the top of the bellows (wind reservoir) until we found the optimum point where the sound was correct and the individual stops of the Diapason Chorus cohered perfectly, so now we can hear the full effect as the organ has subsequently been tuned and regulated at the new lower pressure which now lies at two and three quarter inches (Bevington's norm).

Let me detail the most striking improvements:-

Diapasons - 'sing' and 'gel' as they should.

Great upperwork (especially the Fifteenth and Sesquialtera) - no longer screams at you which now enables the reeds to be heard in perfect blend.
Great Bell Diapason & Swell Voix Celestes - have lost their reedy harshness - now sound smoother and sweeter.

Flutes - All of the flutes have taken on a beautiful 'liquid' tone. The Swell Stopped Diapason (which may have come out of the previous organ) is an exquisite gem and much admired.

Chorus reeds - their 'fire' and brassiness have been restored, without them having to be re-voiced

Another significant improvement concerns the 'touch' of the keyboards. It is now considerably lighter as the pallets do not have to fight against the higher wind pressure any more.

To highlight some of the many excellent features of the organ I would like to tell you know about a few of the individual stops and ensembles ........

The flutes are real gems - the Choir Harmonic Flute and the Leiblich Gedackt deserving special mention. The Great 4' Flute is slightly overblown and produces a mild orchestral "chiff", which is quite attractive. The Choir Vox Angelica was originally called "Dulciana", but was tuned sharp at my request, and when drawn with the Salicional these two stops fill the church with a most beautiful and restful ethereal sound.

The Salicional on the Swell is really too soft to be a perfect partner for the Voix Celestes. However, all is not lost, as they do sound well together (almost like a Viol d’Orchestre) and the latter stop, which is rather "stringy" also blends extremely well with either the Open or Stopped Diapason.

The Great Diapason Chorus (16-2 ft) is truly one of the glories of this organ and Austin Niland's pre-1965 comments were well-founded. It has a singing cohesion which would grace any cathedral organ and when combined with the sparkling Sesquialtera and Trumpet makes a truly inspiring sound. The Swell Chorus Reeds have regained their richness without having to be revoiced and with the Octave coupler and Mixture produce a cathedral-like 'caged tiger' Full Swell. The sound of Full Organ with Full Great and Swell coupled plus the 32' reed is quite spine-tingling.

Many people who have played or heard the organ consider that it now sounds just like a cathedral instrument. One of the comments made about it in a "thank you" letter after an Organists' Association visit was "A MAGNIFICENT ORGAN IN A MAGNIFICENT SETTING". What more need be said? The former Organist of Tewkesbury Abbey on his visit in early 2004 said, "This is a jewel of an organ – a real stunner and must be preserved".

An interesting postscript to all of this is that sound engineers from the Dutch digital organ firm 'Content' visited us in 1998 and sampled the pipework, so it is possible that if you are the lucky purchaser of one of the "English Voicing" models, then you may be privileged to be playing on some stops sampled from this very instrument, which to them epitomised the true 'English' sound more than either of the other local organs they sampled. They were most impressed with the wonderful blend of all the stops. A 3-manual exhibition model was displayed at the Frankfurt Music Fair in the summer of 2000.
