JULIAN RHODES' DREAM ORGANS


ORGAN DESIGNS BY NORMAN COCKER (1889-1953)
PART TWO:
SMALL CHURCH ORGAN DESIGN



Norman Cocker contributed an article about the design of small church instruments to the October 1928 issue of 'The Organ' quarterly. It is so well written, and so full of interesting ideas, that it is reproduced here in its entirety.



SMALL CHURCH ORGAN DESIGN
by
NORMAN COCKER


A small organ containing twenty-two speaking stops has recently been erected by Harrison in the chapel of Jesus College, Cambridge. Originally the instrument was an elderly two-manual without pedals:

GREAT
     8       Open Diapason
     8       Stopt Diapason
     4       Principal
    2 2/3    Twelfth
     2       Fifteenth
    III      Sesquialtera
 
SWELL
     8       Open Diapason
     8       Stopt Diapason
     4       Principal
     4       Open Flute

(This interesting organ was given to the college in 1847 by John Sutton. It was built by J.C. Bishop to Sutton's stoplist incorporating his old-English tonal ideals. Two Father Smith ranks were included. The case was designed by A.W. Pugin.
Cocker's stoplist omits a 4ft. Stopt Flute on Great The Sesquialtera was in fact a two rank stop (19.22), and there was a separate 1 3/5ft. Tierce - j.r.)

Now, if we conventionally-minded folk had been responsible for the enlargement of this little scheme, we should probably have made it look like this:-

GREAT: 16.8.8.8.8.4.4.2 2/3.2.III.8
SWELL: 16.8.8.8.8.4.4.III.8.8.
PEDAL: 16.16.8

(This pastiche scheme, and the following four, were given in full in the original, complete with appropriate couplers, accessories and stop names - j.r.)

The more enlightened among us would call this late Victorian, and suggest instead an up-to-date version:-

GREAT: 16.8.8.8.8.4.4.2 2/3.2
SWELL: 16.8.8.8.4.4.III.16.8.8.
PEDAL: 16.16.8.8.16

(This is a pastiche of Arthur Harrison stoplists - j.r.)

The French organ builder aims first and foremost at blend and ensemble, plus a well-stocked pedal department. He would probably suggest:-

GRANDE: 16.8.8.8.8.4.2 2/3.2.1 3/5.II.8
RÉCIT: 8.8.8.8.4.4.V.8.8
PÉDALE: 16.8.8.4.16.8.4

The German builder thinks on somewhat similar lines, with, if anything, more variety in the pedal 16ft. flues. His swell, however, is often a kind of modern English enclosed choir, containing a large assortment of 8ft. flue stops:-

MAN. I: 16.8.8.8.8.8 (reed).4.2 2/3.2.III
MAN. II: 16.8.8.8.8.8.8 (reed).4.4.III
PEDAL: 16.16.16.8.8.8.16.8

The average American organ builder would consider all these schemes very small beer. He specialises in ear-tickling. Ensemble to him means nothing. So he would hand out something after this kind:-

GREAT (encl.): 8.8.8.8.8 (celeste).4.4.2.8.Chimes
SWELL: 16.8.8.8.8.4.2 2/3.2.8.8.8.Harp
PEDAL: 32.16.16.8.8

Mr. Arthur Harrison, however, has evolved quite a different type of scheme. At least we may be sure he had a hand in it. Instead of adding stops to the two original departments, he has left these departments intact, and added two more, complete with separate manuals. The result is a baby four-manual:-

GREAT (new)
    16       Double Salicional
     8       Open Diapason
     8       Hohl Flute
     4       Octave
             Swell to Great
             Choir to Great
 
SWELL (new)
     8       Viol di Gamba
     8       Harmonic Flute
     4       Concert Flute
     8       Trumpet
             Echo to Swell
 
CHOIR (old Great)
     8       Open Diapason
     8       Stopt Diapason
     4       Principal
     4       Stopt Flute
    2 2/3    Twelfth
     2       Fifteenth
    1 3/5    Tierce
    II       Sesquialtera
 
ECHO (old Swell)
     8       Open Diapason
     8       Stopt Diapason
     4       Principal
     4       Open Flute
 
PEDAL
    16       Open Wood
    16       Sub Bass
             4 pedal couplers

Apart from the unfortunate lack of couplers (Cocker has omitted the Swell octave and Swell to Choir couplers - j.r.) and 8ft. pedal stops - owing perhaps to lack of space and funds - the scheme is delightfully unorthodox and suggestive of many possibilities. A month's holiday in Cambridge with unlimited access to the instrument and a well-stocked music library would be a boon to most of us. We should learn to think organically in quite an unusual manner.

By skimming off the cream of the Continental and American ideas and co-ordinatinmg it with Mr. Harrison's freshness of outlook, we ought to be able to evolve some interesting small organ schemes.

We may tabulate the cream:-

The Frenchman likes (1) a complete great diapason family; (2) a pedal well equipped with 8ft. and 4ft. flues, and always with reeds.
The German likes (1) a complete great diapason family; (2) a pedal well equipped with 16ft. and 8ft. flues and reeds, and one largely independent of manual to pedal couplers.
The American likes (1) more than one swell-box; (2) 73-note soundboards for the sake of the super couplers; (3) percussions (chimes, harp, &c.)
The Englishman likes (1) a complete great (but he is content with, and usuallly gets, far less); (2) a good full swell.

Now, it is clearly impossible adequately to design an organ without knowing the purpose for which the instrument is to be used. The French organ is built for improvisation, and for the performance of French organ music and Bach. The German organ is built chiefly with an eye to congregational accompaniment, and to the performance of the eminently solid German organ music. The American instrument is used apparently as if it were a Jack-of-all-trades, though judging from the majority of published stop-lists, it is good for one job only, and that job is ear-tickling. And from all accounts it does it supremely well. The English instrument is employed primarily for the acompaniment of voices, secondarily for service voluntaries, and only occasionally for recitals. In its general tonal design, it stands halfway betwen its American and Continental brethren, for it contains sweetmeats for the women and children, and beef, beer and cheese for the men; and everything plain and wholesome. Continental organs in many instances certainly are its equals in all these comestibles. They score heavily, of course, with their luxurious pedals: but they invariably lack that essentially English effect known as the full swell. America generally has still to be introduced to ensemble effects of any kind. There are exceptions, particularly in the work of Skinner and the French-Canadian builder, Casavant. American organs, however, are mechanically ahead of the lot of us; so that it seems as if Continental ideas concerning the great and pedal, combined with English voicing, the English full swell, and American action, should produce the organ par excellence. On these lines the tonal basis of the smallest church organ of more than one manual should be:-

GREAT
     8       Open Diapason
     4       Principal
             Swell to Great
 
SWELL (73-note soundboard)
     8       Trumpet
             Sub
             Super
 
PEDAL
    16       Bourdon
     8       Flute
     8       Octave (metal)

(Cocker is being deliberately provocative, particularly in the Britain of 1928, by giving the Pedal as many registers as the two manuals combined - j.r.)

This provides a minimum of great ensemble, a full swell effect, and an independent pedal, and it would be capable of leading the congregational singing in a village church. And in the rendering of many a big organ piece it could give a better account of itself than scores of organs more than double its size. To make it serviceable for lighter accompaniments and soft voluntaries, it only needs the addition of a few quiet stops. These should be distributed amongst the two departments and placed, if possible, in two swell boxes:-

GREAT (73-note soundboard)
     8       Open Diapason
     4       Octave
             enclosed:
     8       Dolce (stopped bass)
     4       Stopped Flute
             Sub          )
             Super        ) playing through the Great to Swell coupler
             Unison Off   )
             Tremulant
             Swell to Great
 
SWELL (73-note soundboard)
     8       Lieblich Gedackt
     8       Salicional
     4       Octave Viol
     8       Trumpet
             Sub          )
             Super        ) playing through the Swell to Great coupler
             Unison Off   )
             Tremulant
             Enclosed Great to Swell
             Unenclosed Great to Swell
 
PEDAL
    16       Bourdon
     8       Flute
     8       Octave (metal)
     4       Flute

Great. - The choice of a dolce (with its stopped bass) in place of a dulciana enables us to keep the great box small.
Swell. - Thanks to the viol 4ft. and the octave couplers, three miniature full swell effects are possible:-
l. Salicional l6ft. 8ft. 4ft.
2. Salicional l6ft. 8ft., viol 8ft. 4ft.
3. Salicional l6ft. 8ft. 4ft., viol 8ft. 4ft. 2ft.

and two "grand" ones:-
4. Trumpet l6ft. 8ft. 4ft.
5. Trumpet l6ft. 8ft. 4ft., viol 8ft. 4ft. 2ft.

(Cocker has passed in silence over the most unusual feature of his scheme, and of those following: the partial enclosure of the Great division. This was practically unknown in British church organs at the time. Cocker's schemes are considerably more colourful and versatile than extant organs of a similar size, other commentators would have pointed out that the second swell box and the complement of couplers make for an expensive instrument; they would also have lamented the concentration on variety of colour rather than strong choruses - j.r.)

The omission of all l6ft. and 8ft. flue stops from the combination known as full swell is at all times desirable. A (luxurious) l6ft. string stop in place of a l6ft. reed is the only exception. After all, the core of a full swell combination is emphatically neither diapason nor flute tone. It is trumpet tone at l6ft., 8ft. and 4ft. pitches, together with a 2ft. and mixture superstructure of either bright diapason or keen string tone. These components are not available on small organs: so we must content ourselves with a makeshift:-

Trumpet tone at 8ft. pitch,
Diapason or string tone at 4ft. pitch,
Sub and super couplers, and
A 73-note soundboard (the extra octave being at the top).

Unfortunately, with tenor C as the downward limit of this combination, the compass is only four octaves. With the more usual 61-note soundboard, the range would only be a paltry three octaves. Still, with only three octaves of good full swell tone much can be done. Helped out with the pedal, they are adequate for most practical purposes in simple service accompaniment; while even for Bach himself our modern top C to C octave is unnecessary.

But not until we reach the luxurious 16ft. reed stage will the five-octave full swell emerge in all its glory. Add to it, however, 16ft. and 8ft. flue stops, and you will thicken and muddy it, and detract appreciably from its clarity and sparkle. Besides, you will consume unnecessary wind and so deprive (in inferior instruments) some of the pipes of their fair share.

Apart from the full swell ingredients, the choice of the 16ft. and 8ft. swell flue equipment is a matter of taste, expediency, and money; and there is at least a good French precedent for the choice of a string céleste and a flute 8ft. before that of a diapason.

Here is a slightly larger scheme containing more colour:-

GREAT     
             enclosed (73-note soundboard):
     8       Salicional
     8       Flûte Harmonique
     4       Salicet     
             Sub          )
             Super        ) playing through the Enclosed Great to Swell coupler
             Unison Off   )
             Tremulant
             unenclosed (61-note soundboard): 
     8       Open Diapason
     4       Principal
             Swell to Great
 
SWELL (73-note soundboard)
     8       Echo Gamba
     8       Cor de Nuit
     4       Flûte Douce
     8       Trumpet
             Sub          )
             Super        ) playing through the Swell to Great coupler
             Unison Off   )
             Tremulant
             Enclosed Great to Swell
             Unenclosed Great to Swell
 
PEDAL
    16       Sub Bass
     8       Flûte               (sic - j.r.)
     8       Principal (large)
     4       Fifteenth

Great. - The enclosed section contains a potential 16ft., 8ft., 4ft. and 2ft. salicional family, which would form an attractive distant full swell-like background to the diapason. With electric action and the right treatment, the salicet could be a 12-note extension of the salicional. Note that on the great the useful 4ft. flute can be had by means of the super and unison off couplers, and so added to the diapason by those who like it.
Swell. - This is not so rich in ensemble effects as No.1; but there is more colour contrast in the flue work.
Pedal. - An unusual choice for an English organ. All these pedal schemes are unusual: they have the great merit of independence, and to Bach lovers they would be an especial joy. Such pedal departments are long overdue in England.

The introduction of a manual double and some enclosed pedal comes next:-

GREAT (73-note soundboard)     
             enclosed:
     8       Dulciana
     8       Hohlflöte
     4       Orchestral Flute
             Harmonic Gongs, 30 bars
             Sub 
             Super
             Unison Off
             Tremulant
             unenclosed: 
    16       Contra Dolce
     8       Open Diapason
     4       Octave
             Super
             Unison Off
             Swell to Great
 
SWELL (73-note soundboard)
     8       Viol di Gamba
     8       Echo Salicional
     8       Voix Célestes
     8       Stopped Diapason
     4       Gambette
     8       Trumpet
             Sub
             Super
             Unison Off
             Tremulant
             Enclosed Great to Swell
             Unenclosed Great to Swell
 
PEDAL
             from Great:
    16       Dolce
     8       Flauto Dolce
             in Great box:
    16       Geigen
     8       Geigen
             unenclosed:
    16       Bourdon
     8       Flute
     4       Flute

Here is an instrument fit for recital use. The gongs would be charming, even in choir accompaniment; and if a little more money were available, the insertion of either a five-octave dulcitone (tuning forks) or a Mustel celesta (steel bars) would be well worth while. The pedal is luxurious.

(Cocker reveals himself as a tonal sensualist, delighting in the interplay of subtle colours and putting them above complete choruses in importance. This, and the percussions, would have been regarded a frivolous by those like George Dixon whose priority was a 'logical' and 'scientific' ensemble. Cocker's scheme would certainly score points in high-church service accompaniment - j.r.)

When a department can boast a family of four stops, it is worthy of a separate manual; so that if a wealthy parishoner could be persuaded to sign a cheque, the enclosed section of the great could be made playable advantageously from a third row of keys.

The introduction of a double reed will be preferable to most players to that of percussions:-

GREAT  (73-note soundboard)     
             enclosed:
     8       Salicional
     8       Vox Angelica
     8       Claribel Flute     
             Sub          
             Super
             Unison Off
             Tremulant
             unenclosed:

     4       Octave
             Super
             Swell to Great
 
SWELL (73-note soundboard)
     8       Lieblich Gedackt
     8       Echo Viole
     8       Viole Céleste
     4       Gemshorn

     8       Trumpet
             Super

PEDAL
    16       Sub Bass
     8       Flute
     4       Flute
    16       Oboe (Swell)

With a bold, bright gemshorn and with the reeds treated quietly but on Father Willis lines, the swell fifteenth could be omitted for the sake of economy. This scheme would be appropriate for an Anglo-Catholic church in which the more delicate side of choir training received stress. The enclosed great section (treated also on Willis lines) would form a useful background for the accompaniment of plainsong and boys' voices. The instrument would give a good account of itself in the performance of most organ music; but for the bigger organ works in general, some more pedal would be needed.

Here is a comprehensive scheme in miniature, suitable for recital as well as accompanimental work. It is quite a multim in parvo; and in fact, with total enclosure, it would not disgrace itself in a small cinema.

GREAT  (73-note soundboard)     
             enclosed:
     8       Echo Dulciana             Hunter type

PEDAL
    16       Open Wood

     8       Echo Flute
     4       Octave  (metal; in the Great box)
     4       Flute  (in the Swell box)
    16       Hautboy (Swell)

Where heavy congregational accompaniment was not required, the lighter but more colourful violone 16ft. would be preferable to the pedal open wood 16ft. and 8ft. Where space and money were not available for either choice, the great open diapason or swell geigen (box-room permitting) could be extended, Compton fashion, twelve pipes downward to form a solitary open metal 16ft. pedal bass. In any case, this is a luxurious pedal in which a cunning player would revel. For a remote country church where recitals would be redundant, it should be curtailed to

    16       Bourdon  (Great)
    16       Sub Bass     
     8       Flute    
     4       Flute 
    16       Hautboy  (Swell)

(Cocker is evidently being ironic; for a "remote country church" the whole stoplist would have been outrageously avant-garde and comprehensive - j.r.)

And for a town church, the enclosed section of the great should be given a separate manual of its own and labelled "choir organ". A slight recast of the scheme would lessen the cost of this extra manual:-

(There seems to be a mistake in the Pedal stoplist. Presumably one of the 8ft. flutes is repeated in error; and is perhaps meant to be a 4ft. stop - j.r.)

There are many possible variations of this. Here is a still less expensive though perhaps equally effective scheme in French dressing:-

(Cocker's misuse of the term 'Cornet' is no worse than that of other British organists of his day - j.r.)

The French nomenclature, introduced for variety's sake, seems to impart a new flavour to the scheme, though the choir 8ft. flues (the viole d'orchestre is an English stop) and the swell salicional are out of the picture. The choir is the weak spot in the instrument; first, because without a soft neutral dulciana and and octave coupler its possibilities as an accompaniment to solo stops are too limited; and secondly, because the clarinet is not in a position to make its insertion worth while except as a luxury. The principal object of two swell boxes is flexibility; not only as regards ensemble, but also as regards expressive solo combinations and their equally important expressive accompaniment. Enterprising organists do not confine themselves only to the more usual solo stops, but in their constant search for variety they find opportunities of using even the lowest octaves of 4fts. and 2 fts. and the upper octaves of 16fts. for solo purposes. Continental players frequently employ solo combinations containing mixtures. The adequate and varied accompaniment of solo combinations is therefore important. On this scheme the choir contains no stop suitable for the accompaniment of a solo on the swell 8ft. and 4ft. flue work. The clarinet is in the way. Here is the solution:-

CHOIR  (enclosed; 73-note soundboard)         
     8       Claribel Flute
     8       Viole d'Orchestre
     8       Dulciana
     4       Flûte Douce           
 
SWELL     
     8       Bourdon

    16       Bass Clarinet
     8       Trompette

The clarinet is now worth its place in the team; and, at the expense of its largely uneccesary top octave, it combines its normal duty of solo work with the more satisfying task of enriching the swell ensemble.

With an enterprising organist to handle it an effective organ could be built of this:-

To the conservative minded, the three percussions will seem outrageous in a church organ. They would be tolerated in an orchestra in church (though some, no doubt, would even consider an ecclesiastical orchestra out of place); and besides, we are bidden to praise the Lord with harp, sackbut, psaltery, lute, timbrels, and all kinds of music. So I fail to see why in the absence of performers upon these instruments we should confine ourselves solely to organ pipes. After all, when we have all heard a cinema organist of the calibre of Quentin Maclean or Charles Saxby perform entertaining light music upon the organ, I am sure we shall renounce the idea once and for all that the organ is essentially a sacred instrument. It is rightly regarded as a suitable medium for the rendering of sacred music, but it is equally well adapted to secular music; and the role of entertainer is one which it can always undertake with complete success, otherwise we may be sure that the cinema world would not have welcomed it so universally.

(One thinks also of the organ's origins in Hellenistic Egypt, and its migration to Byzantium; in both places it fulfilled a purely secular role very successfuly - j.r.)

It is reasonable to argue that the church organist would not know how, when and where to use percussions. But there are many church organists who do not appear to know how to use an open diapason.

Our schemes so far have not been lavishly provided with great ensemble material. This needs explanation.

A great cannot be considered wholly complete unless it be equipped with a diapason family consisting of 16ft. 8ft. 4ft. 2 2/3ft. 2ft. and mixture, topped by reeds 16ft. 8ft. 4ft.; and failing the necessary space and money with which to build such a great, together with a swell of equal completeness, we have to divide the honours between the two departments:-

Great. - Diapasons 16ft. 8ft. 4ft.
Swell. - Diapasons 2ft. mixture, reeds 16ft. 8ft. 4ft.

These departments combined will then reproduce precisely the ensemble itself in miniature. If space and money even for this be still lacking, we first subtract the swell mixture, and secondly the great 16ft, obtaining the swell 16ft. 8ft. 4ft. effect from a reed 8ft. and sub and super couplers:-

Great. - Diapasons 8ft. 4ft.
Swell. - Diapason 2ft., reed 8ft., sub, super.

The result will not be ideal and its scope will be limited; but if the stops be cunningly voiced by the builder and intelligently used by the player, the result at any rate will be satisfying.

In this light we will examine the possibilities of the re-scheming of an average two-manual of the type quoted at the beginning of these remarks, - that containing great diapasons l6ft. 8ft. 4ft. 2 2/3ft. 2ft. mixture, and a chorus reed 8ft. on both swell and great. Now, if the reed families were complete, or if they could be made synthetically complete by means of sub and super couplers, the full great would virtually become an unenclosed duplicate of the full swell. In other words, the great would be complementary to the swell in that it would superimpose upon it further climactic tone of a similar nature.

But mere duplication of tone is not desirable. What is desirable is variety of tone, consistent with blend. Accordingly, the enterprising and artistic organ-builder studies varieties of family ensemble treatment. First, diapason tone of which Bonavia Hunt describes two main types: (1) the Schulze, and (2) the archaic or foundational. The first is of that brilliant quality (with an "edge" to it) produced by such men as Schulze, Father Willis, Lewis, the modern Willis, Rushworth & Dreaper, and others; while the second is more weighty (with "cathedral roll") of the kind to be found in the older organs by Hill, Gray & Davison, Walker, and in later instruments by Harrison and others. Hope-Jones carried the foundational type to its extremity. I prefer to call these types:-

1. The geigen, as pertaining more towards string tone.
2. The foundational, as pertaining more towards flute tone.

But I dream of yet a third type, and that the most charming (though not perhaps the most inspiring) of all. Is it the Silbermann type? It is said that Silbermann diapasons are "silvery." Anyhow, I can imagine a family of light-winded, light-sounding diapasons which have neither edge nor weight, which are bright without being brilliant, which sound slender and clean, which are both placid and dainty, and which, above all, have no trace of flutiness in their tonal make up. "Silvery" seems to sum them up most aptly. Where can such diapasons be heard?

(In 1928 'The Organ' did not yet include articles by Cecil Clutton and others which would, in the forthcoming years, answer Cocker's questions so thoroughly - j.r.)

These three types, then, could be apportioned on a large organ to the three main manual departments:-

1. Swell: the home of fire, - the geigen.
2. Great: the home of weight, - the foundational.
3. Choir: the home of grace, - the silvery.

It is necessary to understand their individual blending propensities:-

1. The geigens blend well.
2. The silvery ones blend less well.
3. The foundationals blend least well.

According to the best modern practice, a compromise is made in regard to the blending problems of the foundational by steering a middle course between the geigen at the one extreme and the Hope-Jones ultra-smooth diapason at the other. In other words, a measure of brilliance and blend is sacrificed to weight, and a small quantity of weight is sacrificed to brilliance. The result is an ensemble which is inferior to that of the geigen school (which has a great deal) and infinitely superior to that of the Hope-Jones school (which has scarcely any), but which at the same time is sufficiently effective for all practical purposes.

Second, chorus reed tone. There are four main types, although the first is not recognised by the best builders to-day:-

1. The old-fashioned, light pressure, thin type at its best, in spite of weak trebles, - the Victorian.
2. The fiery, but still thin, medium pressure Father Willis trumpet; a greatly refined edition of No. 1, with stronger trebles, - the trumpet.
3. The shining, heavier pressure type, with a good deal of clang and grip, like the old Willis tubas and many of the modern Harrison or Hunter great reeds, - the tuba.
4. The modern smooth tromba, which though not altogether lacking in clang yet possesses more body and meatiness than No. 3, - the tromba.

It is, of course, possible to obtain an ultra-smooth ("close") reed - the latest Willis French horn is a beautiful example, and it is so fluty that it is difficult to believe that it is a reed at all - and some of the new tubas and great reeds of to-day are voiced in this manner. Their blending powers, however, are too limited for purely chorus purposes. With effectiveness plus variety as the object in view, we may now set to work upon the original two manual schemes, each of which contains an odd twenty manual speaking stops, and re-scheme them in the light of various types of diapason and reed tone, together with the Harrison ideas in planning and the cream of the ideas of Continental and American builders:-

GREAT  (3 1/2in. wind)
    16       Bourdon
     8       Open Diapason

             Tremulant            
 
PEDAL 
    16       Bourdon  (Great)   
    16       Sub Bass    
     8       Flute
     8       Octave  (metal)
     4       Flute
    16       Fagotto  (Swell)
    16       Trombone  (Choir)

(This is an excellent stoplist, marred only by the rather rigid family grouping of tone colours, particularly the Choir and Echo flutes. The advantage of Schulze and Father Willis Choir divisions was that there were often both Lieblichs and Traversos at 8ft. and 4ft. - the variety of cross-combinations was great - j.r.)

Great. - This consists of a family of silvery diapasons, and a sweet, old-world stopped diapason.
Swell. - This is a complete contrast, with its little geigen family full of brilliance and its splashy trumpet chorus. The usual flute and celeste sweetmeats are allowed the privilege of a separate manual and called "echo," which is a great (but expensive) advantage.
Choir. - Here come the big foundational diapasons: (1) for congregational accompaniment; (2) for use tuba fashion, in contrast with the lighter work of the great; and (3) for use in Continental organ music as a grand orgue (always the lowest manual), to which the great will effectively do duty as a positif, - a great boon in Bach playing. Here also is the 85-note tromba, available on the pedal as an enclosed loud reed, and available also in complete 16ft. 8ft. and 4ft. pitches on the manual for both solo and chorus use. Enclosure will detract from its power and éclat, but its utility will proportionately be enhanced. Here again is the essential accompanimental pianissimo dulciana together with a couple of orchestral flutes.

The conventionally-minded will no doubt consider such a scheme luxurious. They will certainly contend that a complete two-manual is preferable to a sketchy four-manual. The answer lies in the word flexibility ; but flexibility incurs fewer pipes and more mechanism, and thereby less space in many cases is required, though certainly more money. This applies to all the suggested schemes, for when we buy an organ it is the machinery for which we pay the most money, not the pipework.

With electrical assistance we could make use of extension and so compress this scheme into a limited chamber with a negligible loss in effectiveness. The choir tromba is already an extension stop. For the harmonic flutes 8ft. and 4ft., instead of using 146 pipes we could use one rank of 85, the extra dozen at the top being necessary for the super coupler.

The echo lieblichs could be given similarly one rank of 85 pipes instead of 146 ; and the whole of the echo might economically be allowed to share the main swell box, thereby making the swell and echo into one ordinary swell department, but still playable from two rows of keys.

The swell geigens with their 295 pipes could (unscientifically) become one rank of 85 pipes; and the oboe 16ft. and trumpet 8ft., with 146 pipes between them, could be altered to a single trumpet rank of 85 pipes, playable at 16ft. 8ft. and 4ft. pitches like the choir tromba, the swell super coupler being scrapped. And given the right builder, I doubt whether there are many who would notice any difference in the result.

The full swell would then be complete in itself, and would read:-

     8       Geigen
     4       Geigen
    II       Mixture
    16       Double Trumpet
     8       Trumpet
     4       Clarion

The whole scheme would then contain two swell-boxes instead of three, and 1143 pipes instead of 1377. But maybe there are not half-a-dozen builders in the land who could cope successfully with the extensional problems.

Finally, here is a quaint tracker four-manual which I once tried when it stood in the chancel of Ely Cathedral, and which now stands in St. John's College Chapel, Oxford. It is a marvel of compactness, and it was originally built as a chamber organ:-

GREAT
     8       Open Diapason
     8       Stopped Diapason

     8       Stopped Diapason
     4       Flauto Traverso

     2       Harmonic Piccolo

PEDAL
    16       Bourdon
     8       Flute
 
Couplers:  4 to Pedal;  Swell to Great sub, super & unison;
           Choir to Great;  Solo to Great;  Swell to Choir.
Tremulant

It would be interesting to know its age, and the name of its designer and builder.

(The organ was built by Bishop & Son in 1883 for the residence of W.J. Birbeck, 221 Brompton Road, London. Two Snetzler ranks from a bureau organ were later incorporated (Great Stopped Diapason and Choir Open Diapason). After being moved to two more houses in London it went to Eastchurch, Kent, then to Ely, then Oxford; it was in Booton Church, Norfolk, for a while, and finally went to Paston's Grammar School, North Walsham, Norfolk. Other stoplists show slight differences of detail; only the Swell division was enclosed, and had a lever pedal- j.r.)
