JULIAN RHODES' DREAM ORGANS


LIBER ORGANUM : AN 8,276-STOP ORGAN

INTRODUCTION
AVERNUS, STYX, TERRENE & INCEPTUAL LEVELS



THE QUEST FOR VERY LARGE ORGANS

The quest for very large organs is not new. Marking points on the journey include Amiens Cathedral, with 2500 pipes by 1422; the Castle Church at Prague, with 4 manuals and 74 stops by 1588; Ulm Minster, with 100 stops in 1856; and the Royal Albert Hall, London, with 111 stops in 1871.

Today the world's largest organs are in the USA. Each of the 'big three' is strongly individual: the clean, majestic lines of Atlantic City; the teeming, labyrinthine detail of West Point; the warm inclusiveness of the Wanamaker organ. Each has influenced my Liber Organum.

The desire for very large organs has a number of motives. Civic and ecclesiastical pride have played their part, as has the need to project sound in a large building. The desire for a complete tonal palette goes hand in hand with that peculiar richness of sound given by large numbers of pipes sounding together. Stephen Bicknell wrote, on hearing the organ at St. Sulpice: "This tutti is a sound of unbelievable complexity: the ear hears so many consituent components that the mind is dazzled." William H. Barnes, writing about the Wanamaker organ, said: "One of its most satisfying features is the richness and mellowness of tone that is produced by hundreds of stops voiced with a moderate degree of power. The wealth of tonal texture is indescribable."



DESIGNING LIBER ORGANUM

During a period of enforced convalescence in 1989 I toyed with the idea of drawing up an organ stoplist which carried all tonal possibilities to a logical conclusion. The first draft totalled 2,295 stops in 73 divisions played from 7 manuals. A second draft doubled this size. It became apparant that I was constructing a stoplist which was utterly impractical from all normal points of view. It would in effect be impossible to build. It could not realistically be housed anywhere, nor could it be kept in tune. Its extremes of pitch and volume would be incompatible with human hearing. I therefore proceeded with my organ-dream quite without restraint, and a third draft doubled the size of the organ once more. Former subdivisions were expanded and divided, new ones created. The fourth draft, completed in 1995, is the current Liber Organum. It is a more coherent, more colourful remodelling of its predecessor, somewhat reduced in size. All possibilities are far from exhausted, but it seems an appropriate place at which to halt.

This stoplist is that of an 'invisible organ'. Although it will not be made manifest, its structure and concepts are nonetheless real. They may be played upon by the mind of the reader. Moving beyond the bounds of physical possibility, it becomes its own musical cosmos.



GUIDING PRECEPTS FOR THE DESIGN

1. That exploration and development should be pursued without respect for traditional bounds

and thus

2. That there should be no limit on size.

3. That traditional concepts and role-models should be a starting point for the main structures

but equally

4. That new tonal resources should be introduced

and

5. That extra-musical and philosophical symbolism should be incorporated.

6. That duplication should be avoided as far as possible.

7. That it should not be merely eclectic, a compendium of diverse features past and present

and therefore

8. That it must have unity of purpose

and also

9. That despite its size it should maintain measure, balance and proportion in all its parts.



GENERAL NOTES

The registers of Liber Organum are distributed among twelve levels, which have a tenuous connection with normal manual divisions, and form a ladder from lowest to highest, thus:

Avernus
Styx
Terrene
Inceptual
Atrium
Median
Resonance
Nebula
Belvedere
Corona
Aerial
Celestial

Most levels contain several subdivisions. Some are derived from familiar types of manuals and divisions, while others are entirely original. For example, the 'Atrium' level includes subdivisions resembling traditional Positive and Choir models, but also 'Chamois' and 'Iridian' sections which are unlike anything extant.

In most cases, traditional division-types are expanded far beyond normal limits. For example, the Positive subdivision of the Atrium level is itself divided into 12 sections. Two of these include metal and wood principal choruses from 32' to 1/32' as well as other voices; they each have some 170 stops. Pedal sections are located on all levels of the instrument.

While each level is complete within itself, the organ is conceived as a whole: its tonal families and colours are echoed and developed throughout the various levels.

There is no extention or duplexing within the stoplist, although many colours have family members in several pitches. This, together with the introduction of new voices, has resulted in an unusually wide vocabulary of stop-names, including many that are entirely new. Some of these are defined in the introductions to the stoplists; the rest are defined in the glossary of stop-names. Names taken from from non-European languages have usually been Anglicised. Locations are given, when known, of existing organs which use these stop-names; however, they have no connexion with my interpretation of these stop-names.

In the mixturework of the organ, certain stop-names have repeatedly been assigned to various registers. These names imply certain qualities of tone. Like its Italian namesake, the 'Ripieno' is a unison/quint chorus mixture of unforced tone, in the classical tradition. The 'Pleno' is more assertive, somewhat in the romantic fashion of climax-mixtures. The 'Armonia' includes thirds, sevenths and other partials which enrich the ensemble. The 'Farber' (which name means 'colour' in German) comprises odd partials. The 'Paletta' is similar to the 'Farber', but voiced softly to enhance the gentler registers.

Throughout the organ, mutations have been brought together in 'Farber' divisions. A wide variety of pitches is present, including quarter-tones. Voiced softly, they are designed to colour individual registers and ensembles. For this reason they are enclosed in swell-chambers for greater flexibility in mixing the colours of the musical palette. Harmonic-colouring divisions of this sort were first proposed by G.A. Audsley, and appeared at West Point (Moller) and Atlantic City High School (Midmer-Losh).


ABBREVIATIONS & TERMS USED IN THE STOPLIST

'Ac.' (acuta), 'mezzo' and 'gr.' (grave) refer to ranks voiced to emphasise bright, normal and foundational harmonic timbres respectively.

'Angusta' indicates narrow scale. 'Fuerte' indicates brilliant timbre. 'Real' indicates full timbre.

Throughout the stoplist, f = flat; n = natural; sh = sharp; sl. = slightly; v. = very.
In mixture specifications, if 'f' or 'sh' precedes the pitch of a rank, a semitonal change is meant.
If 'f' or 'sh' follows the pitch of a rank, detuning to form a celeste beat is meant.




1. AVERNUS LEVEL
(76 stops)

This is the first of four 'introductory' levels to the organ. There is much extra-musical symbolism here.

The name AVERNUS was given by the Romans to a lake in Campania, believed to be the entrance to the underworld. This division is located in a well beneath the floor, and is subterranean in spirit.

The lower level consists of two choruses:

COR HADES: A 2-rank brass-reed comprising a louder horn rank and a softer, thinner-toned rank of trumpets. The general effect is dark and rich.
CHOEUR HADES: A 3-rank Vox Humana (flat, natural & sharp). Muted, throaty tone.

The middle level includes:

MRU-U-UU-UUU: A piffaro of wooden horn, diapason, clarinet and vox ranks creating a groaning, wailing sound. The ranks are available individually or in any combination. The onomatopaeic name is of Babylonian derivation.
BILUSHAZIRI: A rich, purple-toned brass-reed. The name is Euphratean for 'Lord of the Seed'.
MIRAK: A hard-toned brass-reed. The name is from the Arabic 'Al Marakk', meaning 'the coin'.
ALHAAITH: A fat horn-toned brass-reed. The name is from the Arabic 'Alyat', meaning 'fat tail'.
CHOEUR LABIA: A flue piffaro.

The upper level includes:

MOLTEN FLUTE: A flute piffaro. All pipes open harmonic brass.
TARTARUS: A growling horn. The name, in Greek mythology, refers to that part of the underworld where punishment is meted out.
DOMDANIEL: A thin, hard-toned trumpet. The name, from the Latin 'Domus Danielis', is that of a mythological submarine hall where a magician met with his acolytes - the "infernal cave" of Carlyle.

The pedal registers include:

LEVIATHAN: The lowermost and lowest-pitched stop in the organ, a growling piffaro comrpising ranks of various kinds. The name literally means 'that which twists round' and was, in the Old Testament, applied to a sea-monster (Job 41:1-34; Psalm 74:13).
CHOEUR LINGUA: Like the manual CHOEUR HADES, but comprising only two ranks.

2. STYX LEVEL
(161 stops)


This is the second of the introductory levels. Like Avernus, it contains much extra-musical symbolism.

'Styx' is the name of the mythological river flowing between earth and the underworld. In the stoplist, it therefore lies between Avernus and Terrene.

The name FLUXIT is derived from the Latin verb 'to flow', and refers to the flowing of river waters. It comprises veiled string tone of the salicional type. The registers of the second subdivision are conical.

The two Vox divisions include:

VOX MITERRE: dark-toned registers. The name is derived from 'Middle Earth', used by Tolkein and others.
VOX CHARON: Vocal-toned, mellow registers. The name comes from the ferryman who, in Greek mythology, rows the souls of the dead across the river Styx to Hades.

In the FLAUTO division there are three contrasting families, including:

BONE PIPE: This evokes the primitive flute made from birds' bones.
(See also TIBIA in the stop glossary)

The Chamada family is called:

DMUZZI: A virile-toned, springy chamada horn. This Babylonian name is that of the god also known as Tammuz, who descends to the underworld, returning therefrom each Spring. The uppermost family in the Styx level, it propels us upwards towards the Terrene level.

3. TERRENE LEVEL
(107 stops)


This level contains a further selection of 'character' ensembles and symbolic elements.

This name, from Milton's 'Paradise Lost' (VI-78) means 'of the earth', and there is much earth symbolism in the stop-names.

The LOGGIA division, like those throughout the organ, is a chest which stands at the front of the level and comprises a tonal cameo of specialised/original ranks. Here it is a string-chest containing:

PHORMINX: A piffaro evoking the timbre of the ancient Greek lyre.
GHISHAH: A string of plaintive, nasal timbre evoking the Persian viol.
GETSU: A thin and bland-toned string, evoking the Japanese flat lute.
KWAITARA: A piffaro of gently melodic quality, named after the Arabic instrument, an ancestor of the guitar.
HARDANGER FIDDLE: A piffaro evoking the Norwegian folk instrument, which has bowed strings of gut and sympathetic strings of wire.

The lower section comprises a four-manual and pedal organ with many illustrative stop-names:
FLUTE DU TERRE: A wide-scale chimney flute.
BROWN/LOAMY/FERTILE/GROWING/WHOLE EARTH: These ranks comprise the diapason chorus, of rich, earthy tone.
WALD HORN: An open wood flute of gently horny timbre.
(Midmer-Losh: St. Mark Philadelphia; Atlantic City Convention Hall, and others)
GREEN GRASS: A muted viol celeste.
AVICINIUM: A colouring mixture. The name, which means 'birdsong' in Latin, has sometimes been given to 'toy' bird-stops.
FISTULA RURESTRIS: A rustic-toned oboe. The name means 'rural pipe' in Latin.
HEMIOL: A gentle-toned Musette. The name is derived from Slavic roots meaning 'gentle'.
(Flauto Hemiol: St. Florian Abbey - Chrissman 1774)
MERULA: An open flute of bird-like tone. The name means 'blackbird' in Latin, and was sometimes given to 'toy' bird-stops.
VOX VINOLATA: A bucolic, bubbly Vox Humana. The name comes from the Latin 'Vinolentus', meaning 'drunken'.
(Lund Cathedral - Strand 1836)
STAG HORN: A virile chamada-horn.
The middle section is a chest of symbolic registers:

VOX POPULI: An inescapable register. 'Approx' conveys the mutable loyalty and philosophical beliefs of this register.
VOX SATURNALIA: A burdensome register, heavy with the weight of obligation; transmuted to a higher plane in the registers 'Ordinance' and 'Service Principle' on the Median Level.
LUCIFER: Not Satanic; rather, a light bringer.
TEMENU: A solid, Babylonian diapason. Named after 'Temenos', a sacred enclosure.
ANTARES: This redly glowing reed hits the bull's eye.
ALPHA CENTAURI: Our nearest star presages the uppermost subdivision in the whole Liber Organum, on the Celestial Level. As above, so below.

The upper section contains two tonal families:

AQUARELLE: A mild, neutral-toned Dulciana. The name is French for 'water-colour'.
MEROPE: A warm, round-toned Unda Maris. The name means 'mortal' (and therefore terrene) in Greek.

The registers on Pedal: Loggia include:

KAMANCHA: A gutsy viol, after the Arabic instrument.

Pedal: Lower includes tree symbolism, as well as a tansliteration of 'Krum Horn'. For SALICIS and FAGUS see the main glossary.

Pedal: Upper contains:

SELENE: A cool-toned Dolce. The name is that of the ancient Greek moon-goddess, lover of Pan.

4. INCEPTUAL LEVEL
(122 stops)


This level, which contains recreations of ancient and medieval organ-types, forms a bridge between the symbolic realms of the lowest three levels and the main body of the instrument.

The name 'Inceptual' means 'that which begins'. Its choruses evoke historical organs, preluding the main chorus-structures of the instrument.

The Lower section contains evocations of the earliest organs:

MAGREPHA: An instrument used in Jewish worship in old-testament times. Possibly a kind of bagpipe, it has also been claimed as an early organ. Here it is a 3-rank Musette.
MASHROQUITHA: Another Jewish organ-like instrument.
KTESIBIOS: The name of the inventor of the Hydraulos (the hydraulic organ) in Hellenic Alexandria. Here, it comprises three ranks typically found in the Hydraulii: open and stopped flutes made of copper, and a reed.
PNEUMATICA: A later cousin of the Hydraulus.
SHENG: The Chinese mouth-organ with bamboo pipes.
RHYTUM: The mechanically-blown Greek war-horn, with its single strident reed pipe.

In the BYZANTIA section, we reach the organ in Byzantium and Constantinople. The six chests are all to be tuned in Pythagorean temperament, taking the note named in brackets as the unison of the temperament. The difference between A-flat and G-sharp (cheSts 1 and 6) is taken from the temperament whose unison is C. Necessito is the mother of the three fates: Lachesis (past), Clotho (present) and Atropos (future). The concept behind this selection of divisions, and their names, comes from Joscelyn Godwin's 'Music, Mysticism and Magic' (1987).

The Middle section contains a 'Venta' chest evoking the brassy timbre of the famous 10th-century organ at Winchester, and a 'Blokwerk' evoking the high-gothic organ with its individual tenor and bass registers, several unison diapasons and large 'Hornwerk' chests.

The Upper section contains further organ-types, and includes a smaller Blokwerk with reed stops called:

CANTUS: A thin-toned woodwind reed. The name means 'song' in Latin.
(Residence William Weaver II, New York - Gluck 1990)

(For a detailed account of these fascinating early organs, the standard source remains Jean Perrot's 'The Organ: from its invention in the hellenistic period to the end of the thirteenth century', translated from the French and published in 1971 by OUP.)
