Michael McNeil has designed, constructed, and researched pipe organs since 1973. He was also a research engineer in the disk drive industry with 27 patents. He has authored four hardbound books, among them The Sound of Pipe Organs, several e-publications, and many journal articles.

Editor’s note: Part 1 of this article was published in the August 2018 issue of The Diapason, pages 16–20.

 

The casework in pictures

The entire casework of Opus 161 is executed in solid black walnut, and in the author’s opinion is among the best of Johnson’s cases with its elegant proportions and understated Gothic ornamentation. The window above the entrance of Eastside Presbyterian Church, its original home, displayed similar, restrained Gothic form and ornamentation. Elsworth’s book illustrates a great many of Johnson’s organs, among them Opus 134, built in 1862 for St. Luke’s Episcopal Church in Lanesborough, Massachusetts.¹⁷ Opus 134 has nearly identical stiles and ornamentation, but its proportions do not soar in the elegant manner of Opus 161, perhaps the result of limitations in height. It is ironic that one of Johnson’s best aesthetic creations has languished in anonymity for decades. Many American churches built in the early nineteenth century did not have a provision for a pipe organ, and as a consequence Elsworth noted that most of Johnson’s earlier organs were furnished with sides to the cases of the free-standing organs produced for such churches.¹⁸ As previously noted, Opus 161 originally had such side panels to its casework, and these were found crudely sawn and nailed behind the façade. The Piru church elected to place the façade casework flush with the wall of the church, necessitating the removal of the side panels.

As was typical of nearly all nineteenth century organs, the façade contains no smaller pipes. The side flats contain pipes of the Open Diapason with considerable overlengths. This is the only architectural flaw in this otherwise stunningly designed case. The use of pipes of very different lengths is an important architectural device—it gives a sense of scale, making the larger pipes appear more imposing in contrast. But façades with pipes of extremely different size are more complex and more expensive to make. Compared to the vast majority of nineteenth-century façades, Opus 161 is one of the finest aesthetic designs.

 

The keydesk in pictures

The reader should refer to Part 1 of this series for photographs of the keydesk and stop jambs (August 2018, pages 17–18). Elsworth described the keydesks of Johnson organs from the period of Opus 43, 1855, to Opus 268, 1868:

 

The manual compass was invariably fifty-six notes, from CC to G3. The stop knobs were disposed in vertical rows on each side of the manual keyboards, and always had square shanks with round knobs that had flat faces. Into these faces were set the ivory labels with the stop names. The labels were always engraved in Spencerian script with no pitch indication. The nameplates up to about 1867 or 1868 were of silver, engraved “Wm. A. Johnson, Westfield, Mass.”¹⁹

 

This description provides some evidence that the organ was modified during its installation at Piru. The stop action does indeed have square shanks leading to the bellcranks, but the shafts connecting to the square shanks and leading through the stop jambs are round. The author had initially believed that the stop jambs were original, observing well-worn and professionally installed felt bushings in the openings of the stop jambs. But a more likely explanation is that the round shafts and extant jambs were added at a later date, and this goes a long way to explain the disappearance of the split bass stops, all of which were screwed together to make continuous stops with no splits. And this nicely explains the current specification with 20 controls instead of the 22 controls indicated in the opus list of the Johnson factory.

The organ was initially supplied with a hook-down Swell shoe, normal fare for Johnson’s work of this time. This feature was deleted, and a balanced Swell shoe was installed by crudely re-routing the action of the Great to Pedal coupler rollerboard. Note the added Swell pedal in Figure 7, the missing hook-down pedal in Figure 8, and the damage to the action in Figure 9 and Figure 10. All of this damage was repaired in the 1976 restoration and the original hook-down mechanism refabricated. The figures show the condition of the console prior to the restoration.

 

The key action in pictures

The basic layout of the key action can be seen in Figure 6 in Part 1 of this series (August 2018, page 20). With the exception of the repositioning of the Swell chest and the addition of the balanced Swell pedal, the key and stop action of Opus 161 was well worn but virtually unaltered in 1976. The damage to the trackers on the Pedal couplers from the installation of the balanced Swell pedal was repaired in 1976 with new trackers, wires, felts, and buttons, and basic repairs to the stickers on the Swell to Great coupler were made, but this was a stopgap solution. At this time the console was in need of a complete disassembly and refurbishment of the leather on the couplers, the felts, and the leather buttons. The action was well designed, had served for a period of more than a hundred years, and had survived a move from Stockton to Piru. But the leather facings of the key tails where the coupler stickers made contact and the felts and leather buttons were showing their age. There were no funds for such work in 1976. 

In Johnson’s action we see similarities to Samuel Green. Bicknell writes: 

 

Green introduced or developed numerous refinements to the mechanism. He often arranged pipes from f# up in chromatic order on the soundboards, even in large organs. This reduced the extent to which rollerboards were required. . . . To make the key action readily adjustable the ends of the trackers were fitted with tapped wires and leather buttons. The appearance of Green’s consoles was enhanced by the use of ivory inserts screwed into the heads of the stop knobs, engraved with the name of the stop. . . . Green also usually made keyboards with white naturals and black sharps. . . .²⁰

 

All of these features are found on Opus 161. The photographs of the action were all taken in 1976 prior to the restoration work.

 

The stop action in pictures

The stop action of Opus 161 is conventional, with metal squares and square wooden shanks. The stop action to the Pedal 16′ Double Open Diapason is a ventil valve to the three windchests of that stop, which are placed at the sides (largest pipes, diatonic) and the treble pipes at the back (chromatic). The photographs show the details of the stop action construction.

A description of the stops and general notes on the scaling and voicing

This section provides a detailed description of the stops; two of the Swell stops were not measured (16′ Bourdon and 8′ Stopped Diapason). For the stops which were measured, a table of data in millimeters is shown. The photographs show some details of the construction, although the poor resolution of the camera is regrettable.

As earlier noted, there is a close resemblance between the organs of Samuel Green in late eighteenth century England and the organs of William A. Johnson in nineteenth-century America. Bicknell writes:

 

On the tonal side Green seems to have adopted the trend towards delicacy and developed it still further. . . . Green’s first line of development in securing the effect he desired was to experiment . . . with the scales of the chorus . . . . in 1778 the Open Diapason is larger than the rest of the chorus. . . . The appearance of extra pipes in some ranks, definitely by Green and contemporary with the instruments themselves, together with re-marking of the pipes, suggests that Green took spare pipes with him to the site and rescaled stops during the tonal finishing in the building. This is considerably removed from the standardised scaling and voicing adopted by, for example, Snetzler. The reasons for this become clearer when one understands that Green’s voicing broke new ground in other aspects as well. Delicacy was achieved partly by reduction of the size of the pipe foot and by increasing the amount of nicking. The loss of grandeur in the chorus was made up for by increasing the scales of the extreme basses. . . .²¹

As we will see in the graphical analysis of the data, all of the features mentioned by Bicknell about Samuel Green would apply equally well to Johnson’s Opus 161. Bicknell observes, “Where Snetzler provided a chorus of startling boldness and with all the open metal ranks of equal power, Green introduced refinement and delicacy and modified the power of the off-unison ranks to secure a new kind of blend.”²²

As earlier noted by Elsworth, Johnson’s wind pressure during the period of 1855 to 1868 “was generally between 21⁄2 and 23⁄4 inches (63 and 70 mm), and in rare examples, nearly 3 inches.”²³ The lower wind pressures, narrower scales of the upperwork, and reduced toes produced a sound with restrained brilliance. 

Referring to his conversations with Edwin B. Hedges (1872–1967), a voicer for Johnson organs, Elsworth made some telling observations. In the process of making the pipework, “ . . . the languids were carefully soldered in place, and the flues were properly adjusted.”²⁴ This is a very important comment, because today the flueway is considered a variable for adjusting power in some voicing styles, especially North Germanic voicing. Johnson’s flueways are very open, often the maximum that would produce good speech, even with Johnson’s bold nicking. Power balances, for Johnson as well as Green, were designed into the scales and further adjusted by the voicer at the toe. “The voicing of flue pipes, such as Diapason, Dulcianas, and strings, consists of nicking the languid, cutting up the upper lips to the proper mouth height, and adjusting the positions of the languid and the upper and lower lips. The amount of wind entering the pipe foot must be carefully adjusted by opening or closing the orifice in the pipe toe.”²⁵ There is no direct evidence that William A. Johnson had first-hand knowledge of the 1792 Samuel Green organ delivered to Boston, but the legacy of Green is obvious in Johnson’s work.

A few comments are in order on the nicking and languid treatment. The languids contain a counterface with a negative angle; the more usual angle is vertical, or 90 degrees. The Isnards made a positive-angled counterface at about 75 degrees with a normal bevel at about 45 to 55 degrees. The negative counterface of the Johnson languid is unusual. This languid is nicked at an angle with a knife, cutting a fine nick as deep as halfway into the languid bevel. Long knife cuts were also in evidence inside the lower lip. As a general rule there are the same number of nicks on a languid, regardless of pitch. These languids work well and produce fast speech even when the lower, negative languid bevel shows above the top edge of the lower lip; the upper lip is not pulled out to compensate for this languid position. Ears are generally found up to 1′ in pitch in the principal chorus, but they are very narrow, not extending far in front of the mouth.

Many of the pipes were found in 1976 to be crudely pinched at the top, part of an effort to reduce the pitch to the modern standard. All of this damage was repaired on mandrels, and tuning slides were fitted.

 

Great division

 

8′ Open Diapason 

This is the first stop on the front of the Great windchest. It has zinc resonators from low C to tenor B and planed common metal feet from about tenor E. All pipes from middle C are planed common metal (30% tin, 70% lead). Zinc wind conductors to the façade pipes supply copious wind; the conductor diameters are 38 mm at low C and 25 mm at tenor C. If memory serves, at least one or two of the pipes in the side flats were dummy pipes, implying that the speaking façade pipes extended to tenor D. The façade pipes were tuned with scrolls at the back, which were entirely rolled up as a consequence of the drop in pitch to 440 Hz, where the original pitch was probably closer to 450 Hz. See the earlier notes on the pitch and wind pressure. As with all of the stops in the principal chorus, the ears are very narrow. 

The author feels obligated to point out a grave error he made in the restoration by removing the heavy nicking on the languids of the Open Diapason, and only on this stop. To make the record clear, David Sedlak advised against doing this, and the author regrets that he did not take Sedlak’s advice. These nicks should be renewed in the manner used by Johnson.

8′ Keraulophon

The second stop on the chest, the Keraulophon pipes were found badly pinched at the top along with crudely reduced toe bores in an effort to reduce the pitch. All of the pipes were straightened on mandrels and tuning slides added. Toes that were not damaged were used as a guide for readjusting damaged toes. This stop is voiced with tuning slots and ears, but no beards of any kind. The bass octave is common with the Clarabella, five pipes from tenor C to E have zinc resonators, and the rest have planed common metal resonators. The nicking is bold and often crossed to keep the speech stable. Flueways were often more closed on one side. This is a bolder string than a Dulciana. 

 

8′ Clarabella

This is the third stop on the chest. Bass pipes C to tenor E are stopped wood; the remainder are open wood with lead plates covering the tops for tuning. These lead plates are somewhat closed down to accommodate the lowered pitch. The internal blocks forming the languids are lower than the front plates by 2.0 mm at tenor E, and 1.5 mm at tenor F. The bevel of the upper lip is internal for the open pipes and external for the stopped pipes. The stopped pipes have narrow, slanted strips at the sides of the mouth to form narrow ears; the open pipes have no extra strips functioning as ears. The nicking is deeper and heavier than the pipes of the principal chorus. The scales and voicing of this stop place its power on the same level as the principal chorus foundations. The only concession to power is a greatly reduced mouth width in the bass octave, a concession to its function as a common bass to the Keraulophon. 

The effective inside diameter of a wooden pipe is a calculation of its diagonal, a method proposed by Nolte.²⁶ The potential power of a round pipe is related to the amplitude of the standing wave in the pipe, which is in turn related to its diameter. Following this logic, Nolte has pointed out that the amplitude of a standing wave in a rectangular pipe is related to its widest point, i.e., its diagonal. We often see modern conversions of wood pipe scales by relating their rectangular areas to those of round metal pipes with equivalent areas, but this does not produce balanced power. The consequence is that conventional modern wisdom decrees that wood pipes should be scaled a few half tones narrower than round pipes of equivalent area. This disconnect disappears with Nolte’s observation of the relevance of the diagonal, not equivalent areas. This is not a new idea. Many older organs, e.g., J. A. Silbermann’s organ of 1746 at Marmoutier, show very disjointed scales between the rectangular wood bass of the 16′ Montre and its metal pipes when plotting by equivalent areas. Convert the Silbermann wood bass scales to diagonals and those scales merge seamlessly into the scales of the metal pipes. Diagonal computations of the effective diameters for the Johnson Clarabella can be found in the table, and those calculations are used in the graphical analysis. 

 

4′ Principal

The fourth stop on the chest, the Principal has five zinc resonators from C to E; the rest are all planed common metal. These pipes showed very little damage. The flueway depths are remarkably wide, especially in the treble, and demonstrate that Johnson regulated power entirely at the toe, not the flueway. Such flueway depths are often found in classical French voicing. This data set can be taken as reasonably accurate evidence of Johnson’s unmolested voicing.

 

4′ Flute И CheminОe

 The fifth stop on the chest from tenor C, this is a classically constructed flute in planed common metal with soldered domed tops, chimneys with no tuning mechanism, and very large ears for tuning. Those large ears had been pushed in far enough to virtually touch each other when found in 1976, another effort to reduce the pitch. The cutups were lightly arched. There was considerable handling damage to the flueways. The toes were reasonably intact. The reduction in pressure from 76 mm to 63 mm allowed these pipes to speak much more freely with the ears much more opened (but not completely straightened). The pipe construction becomes open at g#′′, i.e., the last twelve pipes, and they are noticeably wider across the break. The table above shows a calculation of the total resonator length, i.e., the body length plus the chimney, and the percentage of the chimney length to the total length. This gives an idea of the harmonics that Johnson was trying to emphasize with the chimney. At tenor C the chimney is 25% of the total length, emphasizing the fourth harmonic, while at middle C the chimney is 30% of the total length, roughly emphasizing the third harmonic. The chimney progresses to larger percentages of the total length as the pitch rises. The chimney is not a constant percentage of the total length.  The photograph shows the classical construction of this stop. 

 

22Џ3′ Twelfth

The sixth stop on the chest, this stop consists entirely of planed common metal pipes that had minimal damage.

 

2′ Fifteenth

The seventh and last flue stop on the chest, the 2′ Fifteenth continues the trend of extremely deep flueways and closed toes. The flueway depths of this stop are perhaps the largest the author has measured on any organ. Remarkably, this planed, common metal stop has no ears on any pipe, and its sound is exquisite. The toes are very restrained and represent the means of controlling power. The diameter and mouth width scales are considerably narrower than the Open Diapason, continuing the trend of narrower scaling with higher stop pitches, a characteristic introduced by Samuel Green. This progression can be clearly seen in the graphical analysis, in stark contrast to the Hook’s constant scaling of  the principal chorus. By this means Johnson and Green achieved a chorus with more refinement and less impact, but they compensated with very wide scaling of the extreme basses.

 

8′ Trumpet

The extant pipework of this eighth and last stop on the chest was constructed of planed common metal with zinc bottom sections from tenor C to tenor B. The Trumpet has an obscure history. In 1976 only two octaves of pipes were found from tenor C 13 to C 37. These were all in fairly good condition without obvious modifications; some crude slotting of the tops was repaired and the pipes spoke well on 63 mm wind. All of the original pipes were cut to exact length with no tuning slots or scrolls. The bass octave of the Trumpet was originally separated on the slider, but found screwed together in 1976. Interestingly, while the bass topboards were bored and chamfered to receive pipes, the chamfers were not burned in like all other borings on both windchests. With the repositioning of the Swell chest over the Great chest, it was now impossible to reconstruct a full-length bass set of pipes, and a half-length set was fabricated with limited tonal success (a few of the half-length pipes needed mitering to clear the Swell chest). The missing treble pipes were recreated by the firm of Stinkens to scales extrapolated from the original pipework. These were quite successful and a good tonal match. The high treble from c#′′′ to g′′′ were obviously flue pipes, and the rackboard borings provided guidance for their scales. All shallots are brass and are marked “H. T. Levi,” one of the reed voicers for William A. Johnson, according to both Barbara Owen²⁷ and Elsworth.²⁸ This stop bears a strong resemblance to the Trumpet heard in the recording of the Samuel Green organ at Armitage, Staffordshire, England (see the section on Recordings).

The Trumpet was carefully disassembled during the restoration and its measurements carefully tabulated; see the drawings and tables below. Measurements unfortunately omitted were the height of the block and the length and width at the top of the main taper on the tongues.

 

II Mixture

The author added a two-rank mixture in planed common metal to the Great during the 1976 restoration. While the merits of this can be debated, it was added in a manner that did not affect the other stops. A thick oak board was mounted at the back of the key channels, extending backwards and upwards, making this the ninth stop on the Great. The pipework was narrowly scaled in the manner of Johnson, roughly -7 half tones from 2⁄3′ pitch to 1⁄4′ pitch, then widening to about -3 half tones at 1⁄8′ pitch. A great many Johnson organs of this size had mixtures. It should be noted that Johnson mixtures of the time period during which Opus 161 was created were called Sesquialtera, and they included third-sounding ranks. Elsworth states, “ . . . these were composed of 17th, 19th, and 22nd ranks [i.e., 13⁄5′, 11⁄3′, and 1′, the same pitches observed in Samuel Green’s Sesquialteras] with two or three breaks.”²⁹ The mixture added by the author is more typical of later Johnson work in its composition without thirds.

The voicing of the cutups was a fortunate accident, where the pipes were mouth-voiced before realizing that they were left many half tones overlength by the pipemaker. When the cone-tuned pipes were cut to length, it was obvious that the cutups were very high. But this was fortuitous, because it taught the lesson that high cutups can have a superb blend, and this mixture provided a fine sparkling glitter in the plenum with no hint of harshness. There are no ears on any pipes. The toes are relatively more open than what Johnson would have done and the cutups are higher. The mixture composition is as follows:

 

C 2⁄3′ 1⁄2′

c 1′ 2⁄3′

c′ 11⁄3′ 1′

c′′ 2′ 11⁄3′

c′′′ 4′ 2′

 

Barbara Owen noted that William A. Johnson was hired to add a VII Cymbal to the Hook organ.³⁰ This mixture was installed in 1870, and no records indicate how this happened. The political implications invite much speculation, of course. The differences in scaling and voicing of the Johnson mixture relative to the Hook chorus illuminates the different approach to chorus design between Johnson and Hook. We will look at this in detail in the graphical analysis. The Johnson VII Cymbal provides a scintillating crown to the Hook chorus and contains a third-sounding rank. In 1871 William H. Johnson, the son of William A. Johnson, joined his father as a partner in the firm and the mixtures built from that time deleted the third-sounding rank.³¹ ν

Quimby Pipe Organs, 

Warrensburg, Missouri

Two organs in North Carolina

In 2017, Quimby Pipe Organs (QPO) completed the installation of two small-to-medium sized instruments in North Carolina. Both projects incorporated pipework or mechanics from the churches’ preceding instruments, as the work would not have been feasible in either case given all-new construction. However, both projects resulted in organs that function mechanically as if they are all new, and both have entirely new tonal identities that align with modern QPO practice. Accordingly, both have been given QPO opus numbers, and each is, in its own way, an exploration of what should constitute a modern-day American multum in parvo organ, where comparatively few ranks of pipes yield surprising results: instruments that are flexible, musical, and artistically satisfying. Each organ plays with the authority of a much larger instrument than its size would suggest.

 

Opus 73

All Saints Episcopal Church

Southern Shores, North Carolina

We were invited to visit All Saints Episcopal Church by Organist and Director of Music Steve Blackstock because we had previously worked with him to relocate an 1878 Marshall Brothers organ, which was electrified and rebuilt by Ernest M. Skinner in 1912 and is now situated in a new case on QPO electro-pneumatic slider windchests at Holy Redeemer-by-the-Sea in Kitty Hawk, North Carolina.

Blackstock asked us to assess All Saints’ 1948 M. P. Möller organ, Opus 7721. Originally five unified ranks, the organ had grown to nine, enclosed in a freestanding case in the rear corner of the room. There were some pleasant sounds in the instrument—particularly the stopped wood flute—but the disposition of these voices at various pitches over two manuals and pedal was not entirely successful; there was a lack of flexible, contrasting ensembles.

Several options were investigated, including either the relocation of a mid-nineteenth-century Hook tracker or a mid-twentieth-century Austin. But the ideas that resonated most with Steve were those which Michael Quimby and I developed for the expansion and radical rebuilding of the existing Möller.  

The approach was straightforward: the existing enclosed mechanical chassis would become the Swell, and a new unenclosed Great division would be added on a new Quimby-Blackinton electro-pneumatic slider chest. The best of the existing pipework would be retained, and after careful restoration, rescaling, and revoicing, would find a place in the new tonal concept, though not always at the same pitches or divisions as before. One independent Pedal rank was added—a Pedal Octave that plays at 8′ and 4′.

Although the existing Möller unit windchests were retained in the new Swell, having been releathered recently, efforts were made to provide more of a “straight” ensemble in the Swell, with unification judiciously used for added color and flexibility, rather than to create ensemble.

Not one new pipe was constructed for the project. Rather, ranks were carefully selected from our extensive inventory of nineteenth- and twentieth-century American pipework for integration into the ensemble. The end result is not a patchwork of individual voices, as one might expect, but rather, a cohesive, flexible ensemble. This is not only due to the quality of the vintage pipework, but also to the unique facility of Michael Quimby to identify which ranks will work to achieve the intended result, and also to the ability of Head Voicer Eric Johnson and staff voicers Samantha Koch and Christopher Soer to carry out the work. Also essential is our fully functional pipe shop, where cleaning, restoration, modification, and repair can happen as required alongside construction of new pipes.

Several church members participated in passing pipes into the organ. One couple, key donors to the project, also assisted, and knowing that there were no new pipes in the organ, inquired as to the provenance of the pipes. In response, I told her that the pipe she had in her hand came from an organ formerly at a church in St. Louis, Missouri. She was stunned. She had attended there as a young lady, and it was, in fact, where she had met her husband, who was also helping to pass pipes. We quickly figured out that we were installing pipes that had played at the time that she would have heard the organ—a happy coincidence that added dramatically to the significance of the instrument for these two.

New casework was designed by QPO and constructed by members of the church to expand and complement the existing enclosure. The new casework is intentionally somewhat transparent, and the pipes of the Great division are visible at different times during the day when overhead light passes down from skylights overhead. The façade pipes are vintage zinc basses, here painted with pearlescent white bodies and rose gold mouths, which complement the open, light-filled character of the church. The existing console was rebuilt and placed on a moveable platform dolly.  

The existing 8′ Trumpet was extensively revoiced and extended to play at 16′ and 4′. It is at once brilliant and foundational and forms a grand underpinning for the full ensemble. A pair of early-twentieth-century strings yield characteristic, lush string tone in the Swell, and the unison rank extends down to 16′. The 16′ Contra Viola is surprisingly versatile: in addition to making an effective double to the new Great Diapason chorus, it is soft enough to serve as a whisper bass (with the Swell box closed) under the 8′ Dulciana, yet harmonically intense enough to combine with the 16′ Gedeckt and synthesize a 16′ Diapason.

The organ was completed in September 2017 and was dedicated on Sunday, October 1. On Sunday, October 15, Dorothy Papadakos accompanied the 1920 silent film, The Strange Case of Dr. Jekyll and Mr. Hyde.

 

Opus 74

Central United Methodist Church

Concord, North Carolina

Susan Renz Theodos, director of music at Central United Methodist Church in Concord, North Carolina, contacted us regarding a project for a possible new organ because of her previous experience playing our Opus 34, of three manuals and thirty-three ranks at St. Michael’s Episcopal Church, Litchfield, Connecticut (1992). Developed in tandem with then organist Thomas Brown, Opus 34 is a QPO multum in parvo instrument dating from before our work had shifted into the mature Quimby tonal style.  

In working together with Susan after her visit to a more recent project at St. John’s Episcopal Church in Roanoke, Virginia (Opus 66, 2010), we developed a proposal for an equally effective three-manual organ, slightly expanded, which would have the same versatility and nuance as Opus 34, but expressed according to a more Romantic approach: with heroically scaled chorus work and characteristic, harmonically developed individual voices that lock together into seamless, coherent ensembles.

The resulting instrument makes use of select existing pipework from the church’s former 1973 Casavant (Opus 3179), new pipework constructed by Quimby, and select vintage ranks from QPO inventory. New electro-pneumatic slider windchests were constructed for all straight manual ranks and electro-pneumatic unit ranks for all pedal and extended ranks. The winding system and interior structure of the organ are all new. In order to help make the project more cost-effective, we refurbished and rebuilt a three-manual console, constructed by another builder in 2000, for an organ that is now redundant. With new mahogany interior, console lid, and bench top, the refinished console is a splendid match for the church’s neo-Classical interior.

The use of existing Casavant pipework in combination with our own inventory was attractive to the church, not only because it was fiscally responsible, but because they understood it to be environmentally responsible when compared with new construction, and therefore, good stewardship in several senses. The transformation to the carefully selected principals, flutes, strings, and mutations is stunning; none of the reused ranks bears any resemblance to what existed before. The previous instrument was weak in the unison range, and top-heavy with piercing upperwork. Individual foundation voices were bland and blended poorly, with little support for choral accompaniment or even congregational song. The transformed ranks, having been recomposed, rescaled, and radically revoiced, now form colorful, expressive Diapason ensembles at a wide range of dynamic levels.  

Our approach to rescaling and revoicing old ranks of pipes that came from the church’s previous organ is conceptually similar to the practice of Aristide Cavaillé-Coll in nineteenth-century France. His organs at Notre Dame de Paris and Saint-Sulpice incorporate significant percentages of eighteenth-century Clicquot pipework, but those old ranks of pipes were successfully transformed to contribute to a new tonal aesthetic by Cavaillé-Coll.  

New and vintage reeds were provided, custom voiced in-house; these range from the throaty Cromorne in the Solo-Choir, to the lyrical Oboe and fiery Trumpet in the Swell, to the brilliant Harmonic Trumpet in the Solo-Choir, and finally, the dominating, spectacular Tuba in the Great. The Harmonic Trumpet, available at 16′, 8′, and 4′ on manuals and pedal, can serve in the Great as chorus reeds with the box closed, as a soft or loud 16′ reed in the Pedal, and with the box open as an exciting climax to full organ at all three pitches. The Tuba is intended strictly for solo use and is voiced on 12 inches wind pressure so that individual notes can be heard over full organ.

Also of note are the variety of 8′ and 4′ flutes, several of which are vintage, and which contrast and combine with each other effectively. The Swell strings are revoiced Casavant pipework and contrast a more broadly voiced Viola Pomposa and Celeste in the Solo-Choir.  Together with the Swell Spitzflute and Celeste, a wide range of undulants is provided, which can be combined in surprising ways.

The organ was completed in November 2017 and was dedicated by Bradley Hunter Welch on Sunday morning, April 15, 2018, with a recital following the same afternoon.

Quimby Pipe Organs, Opus 74

Stephen Schnurr

Stephen Schnurr is editor and publisher of The Diapason and director of music for St. Paul Catholic Church, Valparaiso, Indiana. His most recent book, Organs of Oberlin, was published in 2013 by Chauncey Park Press (www.organsofoberlin.com). He has authored several other books and journal articles, principally on pipe organ history in the Great Lakes region.

This article is a continuation of a feature in the August 2015, June 2016, and July 2017 issues of The Diapason. This essay was delivered as a lecture for the Midwinter Pipe Organ Conclave on January 19, 2015, in La Grange, Illinois. The research for this project provides a history of a number of pipe organs in the village, but not all. For instance, organs in residences and theaters are not surveyed.

 

The Convent of the Sisters of St. Joseph in La Grange Park, Illinois, is the home of the Sisters of St. Joseph, established on this site on October 9, 1899, by Mother Stanislaus Leary. Mother Leary had been superior of her order in Kansas and came to Chicago to seek medical help as her health was failing. She was accompanied by others of the order. The pastor of nearby St. Francis Xavier Church, La Grange, invited the sisters to settle in the relatively new suburb.

The sisters opened a school for girls in September 1900. Some of the students were boarders. Soon, the sisters would open another school for boys. Nazareth Academy, now co-educational, is still located on the La Grange Park motherhouse campus.

On July 14, 1900, the cornerstone of a motherhouse and chapel was laid. The chapel contained an organ built in 1929 by M. P. Möller of Hagerstown, Maryland, Opus 5555, a two-manual, eight-rank instrument. The contract was dated March 20 of that year, with a projected completion date of June 1. Cost was $3,200.00, with one-third due upon completion, one-third in two equal payments at four and eight months thereafter, without interest. The electro-pneumatic action organ had a detached console of walnut, with “Gold Bronze” façade pipes and grille. Stop control was by tablets above the upper manual. Wind pressure was 5 inches. Pitch was specified at A=440 Hz. The Chicago agent for Möller, and the installer of the organ, was Ford & Reynolds.

The present chapel of strikingly modern design was built in 1967 and 1968 to the designs of John Voosen of Chicago. The motherhouse and chapel were dedicated on Sunday, September 29, 1968. Sister Mary Victoria Rokos, SSJ (later known as Sister Emily), convent organist, was charged with developing plans for a new organ. She sought the advice of persons at Northwestern University of Evanston. The Möller organ was sold and removed.

The result was a recommendation of the Noack Organ Company of Georgetown, Massachusetts, to build a new two-manual, 20-stop, 31-rank organ of mechanical key and stop action in a free-standing case in an elevated balcony at the rear of the nave. A landmark design for the neo-classical organ revival movement in the Chicago metropolitan area, the organ was to cost what was then a large sum of money, $40,000.

The convent purchased a smaller Noack organ as a temporary instrument until the larger organ was completed, at which time the smaller organ was removed to the Academy on the campus. This organ has since been relocated elsewhere. Opus 42 was inaugurated in recital by James Leland on July 14, 1968. The one-manual, mechanical-action organ was provided with a pull-down pedal.

Roosevelt Organ No. 408

In 2003, I purchased Frank Roosevelt’s three-manual, thirty-six rank Organ No. 408 before the wrecking ball struck Brooklyn’s Schermerhorn Street Evangelical Lutheran Church. The Roosevelt organ, contracted for in 1888, begun in 1889, and completed the following year, enjoyed renown while Franz Liszt’s student, Hugo Troetschel, presented 250 bi-weekly recitals during his 52-year tenure as organist. As the Roosevelt organ was being dismantled, a project was initiated for it to be reconstituted in its historic configuration for Princeton University under the aegis of the late David Messineo, university organist. Dr. Messineo’s vision was to install it within the 1916 Aeolian organ case in Proctor Hall, which had been designed by Ralph Adams Cram as the elegant graduate dining hall of the campus. The Aeolian was supplanted by a Gress-Miles organ in 1968, but we felt that bringing the Roosevelt there, with a replica of its original console and limited combination system, would give students an accurate idea of what an untouched Roosevelt sounded like, and more importantly, how it would have to be played without modern solid-state equipment. Upon Dr. Messineo’s death in June 2004, the project abruptly was ended, so I reserved the material within our company’s selection of heritage pipework until such time as a suitable home could be found for it. 

A decade after saving the Roosevelt from the landfill, it became obvious that it would take a very special type of church, synagogue, homeowner, or school to take the leap of faith to historically reconstruct a heritage cultural property that they could not hear or see. I was left with little choice but to market the Roosevelt as the core of a new instrument, but did not wish to disperse it rank-by-rank, the fate of so many antique instruments. With the understanding that its genes had to carry on in a different way, I knew it was unlikely that all of it could be used, and some contemporary tonal elements might be included to make it viable for modern musical ministry. The goal was to keep its spirit alive.

 

The opportunity presents itself

Saint Patrick Catholic Church is a vast, lofty, reverberant building constructed in 1962 and equipped with M. P. Möller’s Opus 9751 from the start. That gallery organ was the unfortunate product of the joint influence of the firm’s “special tonal consultant,” Ernest White, and their tonal director, John Hose. Too small for the room and voiced barely to energize the pipes, it was from its inception frustratingly inadequate for liturgical use. Sparse allocation of the organ’s twenty-one ranks among three manuals and pedal forced the elimination of essential voices in what likely should have been a well-appointed two-manual instrument. Subsequent alterations to the stoplist accomplished nothing, and the organ was still suffering mechanically after technical work was executed. Upon careful examination, I determined that insurmountable scaling irregularities precluded it from forming an effective core for a new instrument, and that the parish would accrue no benefit from retaining any of its mechanical infrastructure.

I entered into a situation for which ideas already had been presented, so as an architect, organist, and organbuilder, I had to make my case with clarity as the last man “at bat,” and had to risk proposing something so different that it would either be rejected or embraced. I proposed that the Roosevelt organ be incorporated into two new organs at either end of the building, controlled by twin mobile consoles that emphasized the elegant richness of natural materials so that the organs would not be seen as utilities. A single aggressive organ blasting from one end of the very long room would be less effective than two more elegantly voiced instruments dividing the task. With no substantive literature written for an “antiphonal” division, I chose a modified continental model. The labor is divided between the two organs, but the use of assisted rather than mechanical action would make them playable separately, together, or simultaneously by musicians at either end of the building.

Countless volunteer consultants offered their strong opinions about tonal design, builders, and the merits of pipeless sounds, with a nebulous consensus that the Möller organ should be rebuilt, supplemented by an “antiphonal” division, real or artificial. The prevailing notion that circuits and speaker cabinets could fill the artistic gaps with a shrug of the shoulders was proclaimed the path of least resistance. Swimming with vigor against that tide, I proposed two complete all-pipe organs of contrasting character, albeit constitutive elements of a grander whole.

There is always room for a pipe organ, even if there is not the willingness. Each house of prayer holds only so many people and will accommodate the appropriate number of pipes to accompany their voices. Despite the absence of sanctuary chambers and the cries of “no room for pipes,” I proposed the centuries-old practice of suspending the chancel cases from the sheer walls of the building, and designed the large gallery case to embrace the rose window. The organs’ cases complement the architecture without distracting from liturgical proceedings, and the chancel cases are located high enough to remain in tune with the gallery organ.

I am grateful to have worked with and for composer, conductor, organist, and tenor Matthew Koraus, FAGO, director of music, whose enormous talent, vision, commitment, and patience helped bring two new organs to the parish.

 

The new instruments

Roosevelt’s standard wind pressure of 31⁄2 inches determined the wind pressure used for the Saint Patrick instruments. The Roosevelt pipes, once cleaned and winded, would dictate to me the tonal direction of the organ’s new stops. Roosevelt’s work after the first few years deliberately followed a template from which the firm rarely deviated, so even the presumption of “what would the company produce today?” was treading on thin ice. The historical material was a point of departure in a new venture.

Visually, my mission was to design three organ cases that acknowledged the modernity of the church building but would bear my stamp as an architectural classicist. Following half a century of blank white walls, the size and depth of the cases, particularly those that flank the sanctuary, presented “the shock of the new” to some parishioners. With choirs, orchestras, and congregation surrounded and coordinated by sound, the new arrangement has been fully embraced. With a sumptuous mobile console at each end of the building, the liturgical and musical flexibility, and the ability for two musicians to play simultaneously, have fostered a new understanding of the organist’s duties in the parish.

The Gallery Great is anchored by a 16′ Violone, which was rebuilt from the Möller Pedal 16′ Principal. This gives the reader a good idea of just how under-scaled the Möller instrument was. The Roman-mouthed Roosevelt Great 16′ Double Open Diapason—gilded, stenciled, and sand painted—had to be abandoned with the magnificent case in Brooklyn, and sadly went down with the building. Soaring harmonic flutes stand alongside Roosevelt’s signature double-mouthed flute, as well as his wonderful 8′ Trumpet with tin-rich resonators and schiffschen shallots. 

The Great Chorus Mixture is composed slightly lower than most and voiced with some restraint. The original Roosevelt tierce mixture could not be retained as a second mixture for budgetary reasons, and with only one mixture in the division, I opted for a new quint mixture for clarity. The Roosevelt Great tierce mixture has found a new home; it is being included in our firm’s reconstruction of Roosevelt Organ No. 4 of 1873, his earliest surviving effort, at The College of Mount Saint Vincent, overlooking the Hudson River. The Great Mixture had been stolen from that organ in 1969, and the Brooklyn stop will sing again among its siblings. 

The Swell harbors the largest concentration of original tone with nine Roosevelt ranks. The warm 8′ Diapason, often absent from the American Swell, supplants the ubiquitous addiction to the 16′ Bourdon. The new Plein Jeu lends clarity to the Pedal when coupled, with no break from its 15-19-22 composition until G#33. With space and budget for only one Cornet combination, it was placed in the Swell, where it is under expression, can be folded into the reeds, and can enter into dialogue with either the Corno di Bassetto or Clarinet. The Swell reeds are rich and warm for anthem work, a balance made possible by the more brilliant manual reeds elsewhere in the organ.

The Choir division is cast with a nod toward traditional structure, without taking it too far into the neo-Classical realm.  The new muted undulant is completely uncharacteristic of Roosevelt’s work; both brothers preferred a second Choir 8′ string of contrasting character, and the Unda Maris appeared in a mere one percent of their 538-instrument output. Tenor C of the Dulciana is marked #400 408 ECHO Choir DULCET G. MACK JULY 1889; this rank was originally built as the 4′ Dulcet for Roosevelt’s 1892 four-manual, 109-rank magnum opus No. 400 for the Chicago Auditorium Theatre, the pipes for which were in production at the same time. The division’s flute choir and subtle Carillon are joined by a notably bold 8′ Corno di Bassetto. Two commanding Trumpets, one enclosed and one not, play from the Choir manual but are not necessarily of the Choir. The new Herald Trumpet, voiced on six inches wind pressure, is in the expression enclosure, and the 8′ Tromba is the former Swell 8′ Cornopean. At six-inch scale with harmonic spotted metal resonators, it was incorporated into the Saint Patrick Pedal as an 8′ and 4′ unit, with the top 17 pipes retained for its use as a powerful manual Trumpet for processions and fanfares and to cap the full organ without standing apart.

The Gallery Pedal is a stack of independent flue ranks, with Roosevelt’s seismic 16′ Open Wood Bass sitting beneath purely tuned 102⁄3′, 62⁄5′, and 44⁄7′ pitches in the bass to reinforce the 32′ line. The magnificently brassy, rolling 16′ Trombone, with its wooden shallots and blocks and sleeved zinc resonators, is so powerful that it triggered burglar alarms and summoned police during the tonal finishing phase of the project. 

The partially unified organ flanking the sanctuary supports and encourages congregational singing by helping to maintain coordination, tempo, and pitch. The front organ is of a lighter and gentler character than the main organ because of its use in more intimate services and its proximity to the parishioners and clergy, yet it is still large enough to use for the performance of a sizable segment of the concert literature.

The sparkling Great and Positiv inhabit the Gospel case and the mellower Swell, with its Skinner-style Flügel Horn, is in the Epistle case. Roosevelt’s splendid Clarinet takes up residence in the Positiv, and the three 16′ Pedal stops (string, flute, and warm reed) keep the bottom from dropping out. The instrument enjoys its own personality, with the resources to enhance liturgy and to acquit a respectable body of the literature. The two cases are widely spaced. There is directional distinction and balances must be heard in the room, yet the acoustic brings them together in the nave.

The combined organs easily lead large choral forces, support full congregational singing, and contain gentle, accompanimental voices at both ends of the building to provide subtle, evocative, and meditative effects for life cycle events and introspective portions of the Mass. Over the centuries, organbuilders and composers have established particular conventions regarding which stops and combinations of stops must “live” in particular divisions, and if these rules are set aside, many works cannot be played as intended. I have tried to honor those requirements in the design of this dual instrument.

Pipe organ building is an interdisciplinary craft, and every instrument, traditionally the vision of the tonal director, is a group effort. In addition to our significant suppliers (OSI, A. R. Schopp’s Sons, and Peterson Electro-Musical Products), these instruments were made possible by the capable staff of Glück Pipe Organs: Albert Jensen-Moulton, general manager; and technicians Joseph di Salle, Dominic Inferrera, Dan Perina, the late Peter Jensen-Moulton, and Robert Rast.

Michael McNeil

Michael McNeil has designed, constructed, and researched pipe organs since 1973. He was also a research engineer in the disk drive industry with 27 patents. He has authored four hardbound books, among them The Sound of Pipe Organs, several e-publications, and many journal articles.

Preface

Good documentation of organs with enough pipe measurements to permit an analysis of both scaling and voicing is extremely rare. Pipe diameters, mouth widths, and mouth heights (cutups) may be sometimes found, but toe diameters and especially flueway depths are rare. Rarer still are wind system data, allowing a full analysis of wind flow and wind dynamics, parameters that have an enormous impact on the sound of an organ. The reader will find all of this in the following essay on William A. Johnson’s Opus 161.

Good documentation is important for several reasons. We can make useful comparisons with other organs to learn how a specific sound is achieved. And perhaps most importantly, we can document the organ for posterity; while organs are consumed in wars and fires, they are most often replaced or modified with the changing tastes of time. They never survive restorations without changes. Comprehensive documentation may also serve to deter future interventions that intend to “modernize” an organ. Lastly, future restorations of important organs will be more historically accurate if they are based on good documentation.

The mid-nineteenth-century scaling and voicing of William A. Johnson is very similar to the late-eighteenth-century work of the English organbuilder Samuel Green, as evidenced by the data from Johnson’s Opus 16 and Opus 161. Stephen Bicknell provides us with detailed descriptions of Green’s work.¹ Johnson’s scaling is utterly unlike the work of E. & G. G. Hook, whose 1843 Opus 50 for the Methodist Church of Westfield, Massachusetts, set Johnson on a career in organbuilding when he helped the Hooks with its installation.² In this essay we will explore Johnson’s Opus 161 in detail and contrast it with the Opus 322 of the Hooks, both of which were constructed within a year of each other.³ While the Hooks used a Germanic constant scale in their pipe construction, Johnson significantly reduced the scale of his upperwork stops, much in the manner of Samuel Green and classical French builders.

The question arises as to whether Johnson came to his design theory by way of a process of convergent evolution (i.e., independently), or whether he was exposed to the organ Samuel Green shipped to the Battle Square Church in Boston in 1792, and which “was played virtually unaltered for a century,” according to Barbara Owen.⁴ The author suggested to Owen that the Green organ may have had a strong influence on Johnson, but she thought it unlikely that Johnson would have made the long trip from Westfield, far to the west of Boston. 

Travel would indeed have been much more difficult in 1843 when Johnson was exposed to the Hook organ at Westfield. But of some significance was the extension of the Western Railroad from Boston to Westfield in 1843. This new railroad may have been the means by which the Hook organ was shipped to Westfield. Elsworth (see endnote 2) clearly makes the case that Johnson was intoxicated by organbuilding with his exposure to the Hook organ. It is easy to imagine that he would have made a pilgrimage to Boston, at the time a mecca of American organbuilding, perhaps invited by the Hooks to accompany them after finishing their installation in Westfield.⁵

The author was engaged in 1976 by Mrs. Gene Davis, the organist of the Piru Community United Methodist Church, to evaluate the organ at that church. The identity of the organ was in question as no nameplate was in evidence on the console, the organ was barely playable, and its sound was greatly muted by the crude placement of panels in front of the Great division to make it expressive by forcing its sound through the shades of the Swell division above it. An inspection showed that nearly all of the pipework was intact, and a contract was signed to restore the organ to playable condition. The organ was cleaned, the pipes repaired, the few missing pipes replaced, and much of the action repaired by Michael McNeil and David Sedlak.

The church office files produced an undated, typed document that stated: 

 

The pipe organ in the Methodist Church of Piru was built by William Johnson, of Westfield, Mass., in the early 1860s, making it probably the oldest operating pipe organ in California. It was a second-hand organ when transported by sailing ship 17,000 miles around Cape Horn before 1900, and installed in a Roman Catholic Church in San Francisco. After the earthquake and fire of 1906, the organ was moved to another church and probably at this time parts damaged in the quake were replaced. After many more years of service it was retired and put into storage until, in 1935, Mr. Hugh Warring was persuaded to purchase it for the Piru church. It was purchased for the storage cost of $280.

Evidence of a different and more likely provenance was discovered during the removal of pipework and the cleaning of the organ. Three labels were found glued to the bottom of the reservoir (perhaps as patches for leaks). Two labels read: “Geo. Putnam ‘Janitor’ Stockton California July 1 ’99.” A third label read: “From the Periodical Department, Presbyterian Board of Publication, and Sabbath = Schoolwork, Witherspoon Bldg, 1319 Walnut St., Phila. PA.” At a much later time Reverend Thomas Carroll, SJ, noticed that the clues of Stockton, California, and the Presbyterian church correlated to an entry in the opus list of Johnson organs, compiled in Elsworth’s 1984 book, The Johnson Organs. Opus 161 was shipped in 1864 to the “Presbyterian Church, Stockton, Cal. The church is Eastside Presbyterian.” The organ was listed as having two manuals and 22 stops.⁶ At this time such features as couplers and tremulants were counted as “stops,” and this roughly fit the description of the Piru organ. The façade of the Piru organ is also consistent with the architecture of organs built by Johnson in the 1864 time frame. Elsworth’s illustrations include a console layout of Opus 200 (1866) virtually identical to the Piru organ layout; Opus 134 (1862) exhibits the impost, stiles, and Gothic ornamentation of the Piru organ; Opus 183 (1865) has similar pipe flats and also the console layout of the Piru organ.⁷ Many other details verified the Johnson pedigree, among them the inscription “H. T. Levi” on the reed pipes. Barbara Owen pointed out that Levi was Johnson’s reed voicer during the time of manufacture of Opus 161.⁸ The pieces of evidence fell together when Jim Lewis discovered a newspaper photo of Opus 161 in the Eastside Presbyterian Church of Stockton that matched the façade of the Piru organ. The most likely scenario is that Johnson shipped Opus 161 directly to that church. The Gothic architecture of the Johnson façade also reflects the architecture of the Eastside Presbyterian Church façade. A handwritten note on the Piru church document stated: “Pipe organ and art glass memorial windows dedication June 2, 1935 per Fillmore Herald May 31, 1935, a gift of Hugh Warring.”

It is possible that the organ went from the Presbyterian church into storage, and was later moved to its present location in the 1934–1935 time frame. Even so, we can say with nearly absolute certainty that this organ is William A. Johnson’s Opus 161.

 

Tonal design overview

It is obvious from even a casual glance at Elsworth’s study of Johnson organs that the Johnson tonal style was based on a classical principal chorus that included mixtures in all but the more modest instruments. But the voicing style is gentle and refined, and bears great similarity to the late-eighteenth-century English work of Samuel Green, whose meantone organ at Armitage in Staffordshire is an excellent surviving example.⁹ Tuned in meantone, Johnson Opus 161 would easily pass muster as the work of Green. The tonal contrast between Green and Hook is stark, and the Hook data serve as an excellent counterpoint to the data from the Johnson organ. Green was the organbuilder favored by the organizers of the Handel Commemoration Festival of 1784, who went so far as to have one of Green’s organs temporarily installed in Westminster Abbey for that occasion. King George III paid Samuel Green to build an organ for Saint George’s Chapel at Windsor.

Stephen Bicknell’s The History of the English Organ relates important details of Samuel Green’s work that we find in Johnson’s Opus 161. “. . . Green’s voicing broke new ground . . . . Delicacy was achieved partly by reducing the size of the pipe foot and by increasing the amount of nicking. The loss of grandeur in the chorus was made up for by increasing the scales of the extreme basses.”¹⁰ And “Where Snetzler provided a chorus of startling boldness and with all the open metal ranks of equal power, Green introduced refinement and delicacy and modified the power of the off-unison ranks to secure a new kind of blend.”¹¹ The Hooks, like Snetzler, used a constant scale where all of the pipes in the principal chorus at a given pitch had about the same scale and power.

The most basic data set for describing power balances and voicing must include, at a minimum, pipe diameters, widths of mouths, heights of mouths (“cutup”), diameters of foot toe holes, and depths of mouth flueways. The data in this essay are presented in normalized scales for inside pipe diameters, mouth widths, and mouth heights. Tables showing how raw data are converted into normalized scales may be found in the article on the E. & G. G. Hook Opus 322 published in The Diapason, July 2017. The full set of Johnson data and the Excel spreadsheet used to analyze them may be obtained at no charge by emailing the author.¹² Also available is the book The Sound of Pipe Organs, which describes in detail the theory and derivation of the models used in this essay.¹³

 

Pitch, wind pressure, and general notes

The current pitch of the Johnson and Hook organs is dissimilar and should be taken into consideration when observing the scaling charts. The Hook organ is now pitched at A=435.3 Hz at 74 degrees Fahrenheit, while the Johnson organ is now pitched at 440 Hz. The original pitch of the Hook organ was 450 Hz; new low C pipes were added when the pitch was changed to 435 Hz, and the original pipework was moved up a halftone, widening its scales by a halftone. The original pitch of the Johnson organ was approximately 450 Hz; the pipes were lengthened to achieve a lower pitch.¹⁴ The Hook and Johnson organs are both tuned in equal temperament. The wind pressure, water column, of the Hook is 76 mm (3 inches); the Johnson organ was measured at 76 mm static and 70 mm under full flow on the Great division. The pressure was reduced during the restoration to 63 mm static. This allowed the pitch of the pipes to drop, making the adjustment to 440 Hz with fewer changes to the pipe lengths; most of the pipes that were originally cut to length had been crudely pinched at the top to lower their pitch. With the reduction in pressure the ears of the 4′ Flute à Cheminée, with its soldered tops, achieved a more normal position. 

The Piru room acoustic was reasonably efficient, and while the Johnson voicing is very restrained, it was adequate to fill this room on the reduced pressure. The Piru church seats 109, has plastered walls, wood and carpet flooring, and a peaked ceiling about 30 feet high; the reverberation, empty, as heard with normal ears, is well under one second (this is not the measurement used by architects that erroneously reports much longer reverberation). Elsworth relates that “the wind pressure which Johnson used during this period was generally between 21⁄2 and 23⁄4 inches [63.5 and 70 mm], and, in rare examples, nearly 3 inches [76 mm].”¹⁵ The photograph of the original Eastside Presbyterian Church for which the Johnson was designed implies a larger acoustical space than that of the Piru church.

The compass of the Johnson organ is 56 notes in the manuals, C to g′′′, and 27 notes in the pedal, C to d′.

 

Stoplist

The Johnson console was found in poor condition, missing the builder’s nameplate and many of its stop knob faces. Correct stop names were derived from the markings on the pipes and the missing faces were replaced. The original stoplist is reconstructed as follows (Johnson did not use pitch designations):

GREAT

8′ Open Diapason

8′ Keraulophon

8′ Clarabella

4′ Principal

4′ Flute à Cheminée (TC)

22⁄3′ Twelfth

2′ Fifteenth

8′ Trumpet

SWELL

16′ Bourdon (TC)

8′ Open Diapason

8′ Stopped Diapason

8′ Viol d’Amour (TF)

4′ Principal

8′ Hautboy (TF)

Tremolo

PEDAL

16′ Double Open Diapason

 

Couplers

Great to Pedal

Swell to Pedal

Swell to Great

 

Blower signal

The above list adds up to 20 controls. The Johnson company opus list describes Opus 161 as having 22 “stops.” This may have reflected the original intention to supply the organ with stops having split basses, which are commonly found in Johnson specifications. The sliders for the Keraulophon and the Trumpet were found with separate bass sections from C to B, professionally screwed together with the sections from tenor C to d′′′. The two additional bass stops would account for a total of 22 “stops.” There are no extra holes in the stop jambs to indicate the deleted split bass stop actions. The extant stopjambs are apparently a later modification from the time of the installation at Piru or before. Elsworth noted that all Johnson organs of this period were constructed with square stop shanks.¹⁶ The current shanks are round where they pass through the stopjambs and are square where they connect to the stop action.

Several stop knobs were switched during the 1935 installation at Piru; e. g., the Viole d’Amour in the pre-restoration photo of the right jamb belongs in the position noted on the left jamb with the black plastic label “Bell Gamba,” which indeed is how this stop was constructed. The Swell Stopped Diapason was operated by a knob labeled “Principal” [sic]. The illustrations of the left stopjamb and right stopjamb diagrams provide the correct nomenclature as restored in the correct positions, with the incorrect 1935 nomenclature in parentheses ( ) and the correct pitches in brackets [ ].

 

The wind system

The wind system can be modeled from two viewpoints: the restriction of flow from the wind trunks, pallets, channels, and pipe toes; and the dynamics of the wind. Wind dynamics are fully explained in The Sound of Pipe Organs and are a very important aspect of an organ’s ability to sustain a fast tempo with stability or conversely to enhance the grand cadences of historic literature. The data set on the Johnson allows us to model all of these characteristics. Figure 1 shows the Johnson wind flow model.

In Figure 1 we see a table of the pipe toe diameters and their calculated areas; values in red font are calculations or interpolations from the data (e.g., wood pipe toes are difficult to measure when they have wooden wedges to restrict flow). These areas are measured for a single note in each octave of the compass.

A model for the total required wind flow of the full plenum of the organ assumes a maximum of ten pallets (a ten-fingered chord), as described in the table, and the flow is multiplied by the number of the pallets played for each octave in the compass. The sum of the toe areas of all ten manual pallets in the tutti is 5,057 mm². The total area of the manual wind trunks is 38,872 mm², and we see that the wind trunks afford 7.7 times more wind than the tutti requires, so much in fact that the trunks do not at all function as an effective resistance in the system.

Interestingly, the Isnard organ at St. Maximin, France, used the main wind trunk as a strong resistor to dampen Helmholtz resonances in the wind system, and that organ has ratios of wind trunk area to a plenum toe area of only 1.07 for the coupled principal chorus of the Grand-Orgue and Positif, but with no reeds, flutes, or mutations. Helmholtz resonances are the source of what is normally called wind shake, and we would expect some mild wind shake with the Johnson’s large wind ducts and low damping resistance. The author’s notes from 1976 state: “Very little sustained shake . . . a considerable fluctuation in pitch when playing moderately fast legato scales, which stabilizes very rapidly . . . this imparts a shimmer . . . .”

In Figure 1 we also see dimensions of the key channels, pallet openings, and the pallet pull length (estimated from the ratios in the action). These allow us to calculate the relative wind flow of the channels and pallets. We find that there are robust margins in wind flow from the channels to the pipe toes (244% at low C to 737% at high C on the Great). This accounts for the small drop in static pressure at 76 mm to a full flow pressure of 70 mm with all stops drawn. Pallet openings are less robust and flow about 100% of the channel area for the first three octaves and 190% in the high treble.

The underlying dynamics of a wind system are the result of the mass of its bellows plate and the volume of air in the system. These factors produce a natural resonance that can enhance the grand cadences of literature with a long surge in the wind, or it can produce a nervous shake if it is too fast. A grand surge in the wind is characterized by a resonant frequency of less than 2 Hz (cycles per second), and it is most often produced by a weighted bellows. A nervous shake results from a sprung bellows. We correct the latter condition with small concussion bellows in modern organs, but the Johnson organ does not have such devices; instead, it features only a large, weighted, double-rise bellows. 

We can model the dynamic response of an organ by using its wind pressure, the area of the bellows plates, and the combined internal volume of its bellows, wind trunks, and pallet boxes. The model in Figure 2 shows the dynamic response of the current Johnson wind system at a relaxed 1.61 Hz. This low resonant frequency drops further to 1.47 Hz when the pressure is raised to its original value of 76 mm. The author’s notes from 1976 state: “Light ‘give’ on full organ; relatively fast buildup to full flow.” That “light give” is the result of the low resonant frequency of the system. The resonant frequency of the Hook organ was modeled at 1.23 Hz, a value lower than the Johnson, and the Hook chorus does indeed exhibit a slower and grander surge on full organ. Figure 3 shows the modeled resonant frequency at the original pressure of 76 mm for the Johnson organ. The equation for modeling the resonant frequency of a wind system along with a worked example on the 1774 Isnard organ at St. Maximin may be found in The Sound of Pipe Organs, pages 99–113.

The layout in pictures

“Green’s organs stand on an independent building frame with the case erected around it, rather than being supported by the structure of the case itself.”¹⁷ Bicknell’s description of a Samuel Green organ applies equally well to this Johnson organ. The casework is built entirely of black walnut, a wood mentioned by Elsworth in reference to Johnson cases. The organ is situated within the front wall of the church. The original black walnut side panels (typical of early Johnson organs) were found crudely cut up and nailed behind the façade in an effort to make the whole organ expressive through the Swell shades. This had the effect of making the Great division sound like a diminutive Echo division. The typical layout of a Johnson organ is well described by Elsworth: “The framework was arranged to carry the chests of the Great organ and the supporting framework for the Swell, which was usually above the Great organ and slightly to the rear.”¹⁸ Such layouts, shown in Figure 4, are common in nineteenth-century American organbuilding. The walkway behind the Great allowed access to the pipes and pallets placed at the rear of that chest, and the rollerboard to the Swell division was normally placed just behind this walkway, allowing access to the Swell pallets that were placed at the front of the Swell windchest. Opus 161 was installed in an opening in the Piru church that was far too shallow to allow the depth of a rearward placement of the Swell division. 

As a result, there is evidence that the Swell windchest may have been reversed, placing its pallets to the back of the windchest, and the chest brought forward over the Great division. Note the lack of clearance between the 4′ Principal pipe and the bottom of the Swell chest in Figure 5. The internal framework shows signs of crude saw cuts; the order of the notes on the Swell chest is the same as the Great, but it is reversed; the Swell rollerboard appears to have been likewise reversed and now faces toward the walkway where the action and rollers are exposed to damage. 

To say that the Piru layout was cramped would be an understatement; no one weighing over 150 pounds would gain access to the pipes for tuning or to the action for adjustment without damaging the pipework or the key action. The author weighed less (at the time) and was barely able to navigate inside the organ. The current layout is shown in Figure 6. 

It is also possible that the current layout reflects the original layout by Johnson, but that the Swell was simply lowered to fit the height of the Piru church and brought forward to fit the limited depth available, reducing the depth of the walkway.

Muller Pipe Organ Company, Croton, Ohio

Saint Paul the Apostle Parish, Westerville, Ohio

The highlight of Muller Pipe Organ Company’s ninety-fifth anniversary year was the completion of the new pipe organ for Saint Paul the Apostle Parish of Westerville, Ohio, the largest congregation in the Catholic Diocese of Columbus. Our relationship with the parish began as the new building was being designed, and we enjoyed working collaboratively to create a space that would be effective for both worship and music. The result is a handsome brick edifice seating approximately 1,500 parishioners in an acoustically reverberant and visually arresting space. 

John Bryan, music director at St. Paul, and Paul Thornock, then diocesan organ consultant, worked with us as tonal ideas were developed. These conversations produced an eclectic instrument that supports the diverse liturgies of the parish, boldly leads major diocesan events, and accommodates a wide variety of organ repertoire.

Saint Paul boasts an active choral program to match the size of the parish and space. To ensure ample room for these singers, we placed the Positive on the railing, where it is reminiscent of a Rückpositv both in location and sound. The other divisions are in the large main case at the back of the spacious gallery.

Our tonal philosophy dictates a broad, warm sound for the Great division; this was readily accomplished at Saint Paul by a location in the main case. This division’s broadly scaled and boldly voiced principal chorus is the cornerstone of the entire instrument. The smaller-scaled Violone was designed primarily as a 16′ stop, but plays at 8′ pitch and functions as the secondary principal, being both brighter and more articulate. The Tromba is the darkest of the manual trumpets and employs English shallots and harmonic resonators beginning in the middle octave. Because the division is expressive, the Great includes ranks that would be expected in a Choir division: a throaty Clarinet and a pair of tapered Gemshorns.

The Swell is the workhorse of the organ and balances the Great division. A secondary principal chorus with a low-pitched mixture, an independent flute chorus, and broadly scaled Viole strings provide a solid platform for choral accompaniment. The Trompette and Clairon create a fiery French effect. The Hautbois, with its open shallots, also has a bright French quality or nasality. 

The Positive contains the most articulate and colorful stops of the organ. Its location on the gallery rail allowed us to contrast its voice with the Great by means of smaller scaling, lower wind pressure, and gentler voicing. The somewhat unconventional Quintadena provides a lovely solo voice and offers an alternative to the eloquent Gedeckt. The Positive Trompet is a median between the Great and Swell trumpets. These shallots were designed for effective tone on light wind pressure, providing plenty of power with ample fundamental tone.   

The pipes of the Pedal division are divided into C and C-sharp sections on either side of the main case. It boasts a powerful Trombone as well as a reclaimed 16′ Open Wood Diapason. Like each manual division, the Pedal has a complete and independent principal chorus, culminating with a four-rank mixture. To provide flexibility, the Pedal division includes judicious borrowing from the manual divisions.  

The visually and aurally commanding Pontifical Trumpet is mounted horizontally on the main case and is constructed of brass with flared resonators. This stop is powerful enough to speak over fuller combinations, yet does so with a refined, even tone.  

The cases were conceived to visually harmonize with the Romanesque features of the building. From the choir seating in the balcony, the outline of the Positive pipework mirrors the architecture of the ceiling and mural while drawing one’s focus directly to the liturgy at the front of the church. The casework and the console were fabricated by craftsmen at the Muller shop. The cases of quarter-sawn red oak were handcrafted using traditional joinery, as was the raised panel console. The console is movable and features interior accents of solid walnut with inlays of ebony and maple. 

We are especially grateful for the support of A. R. Schopp’s Sons, Inc., David R. Beck, Paul Thornock, and countless others in the industry for their counsel and wisdom. However, the instrument would not exist without the heroic efforts of John Bryan, the Reverend Charles Klinger, pastor, and the parishioners of Saint Paul the Apostle. We thank them all for honoring us with the opportunity to build this lasting testimony to their faithfulness.
