The “Turkish” Percussions
Between the first and the second decades of the 18th century (available documents do not agree on the exact timing) the Ottoman Sultan Ahmed III sent as a gift to the Polish King a complete Turkish military band. Such type of musical band was already known in Europe, both because the Turkish diplomatic delegations were accompanied by such bands, and also for having been heard during the wars against the Turks. In 1683, the Austrian troops and population, during the siege of Vienna, were psychologically troubled by a Turkish musical band that was playing after prayer times during the day, and at sunrise and sunset.
One of the peculiarities of the “Turkish” music was the great importance (and loudness) of the percussions. The bass drum (Photos 7 and 8), the crash cymbals (Photo 9), the “Sistro” or “Chinese hat” (Turkish crescent or Jingling Johnny54) (Photo 10), and the triangle impressed and captivated European musicians, who, starting from the second half of 1700, adopted them in their musical creations. One of the first to utilize them was Gluck (probably on that occasion, but even in prior performances of his works, like the Cadi Dupé, in 1761, by hiring Turkish musicians who lived in Vienna at the time) for his opera La rencontre imprévue ou Les Pèlerins de Mecque (1764). It was an opera that even Mozart likely heard and appreciated, to the point that he wrote the twelve variations in G major, K. 455, on the theme from an aria of La rencontre. Since then, many musicians have adopted both the style and the instrumentation of Turkish music. Mozart, in 1775, wrote a concerto for violin (no. 5 in A major, K. 219) sometimes named “Turkish” for the peculiar structure of the last tempo; in 1778, the piano sonata in A major, K. 331, with the famous rondo “Alla turca” (“in Turkish style”); and, in 1782, the opera Die Entführung aus dem Serail. But even Haydn (for example in the symphonies 63, 69, and 100) and then Beethoven (from Die Ruinen von Athen in 1812 until the last movement of the Ninth Symphony) and even the musicians of the Strauss dynasty adopted Turkish instrumentations and styles.55 In a matter of a very few years, composers and orchestras throughout Europe adopted the exotic Viennese acquisitions.
Manufacturers of fortepianos were also fascinated by the instrumentation “in the Turkish style,” and around the year 1800 they began to manufacture instruments that included a stop called “Turkish music”56 or Janitscharenzung, consisting of a pedal-activated mechanism hitting the soundboard and also activating a sort of Chinese hat.
After the Congress of Vienna, most of northern Italy (the present regions of Lombardy, Veneto, Trentino, and Friuli-Venezia Giulia) fell under Austrian rule. This undoubtedly facilitated the transferring of ideas and merchandise between Italy and Austria. There are many Viennese-made fortepianos today in public and private collections, and many of them came to Italy during that period.
The popularity of opera in the 18th and 19th centuries and at the beginning of the 20th in Italy is a phenomenon that is being studied from every possible angle. An interesting aspect is the great appreciation, almost a sort of fan-like exaltation, of the music of Verdi, which had a strong political connotation, being linked to a sort of underground rebellion against Austrian rule and against all other oppressors of the Italian people. Often, one could find “W VERDI” graffiti, not referring to composer Giuseppe Verdi, but instead an acronym of the phrase Viva (long life to) Vittorio Emanuele Re (king) D’ Italia (of Italy), the Savoy dynasty King of Piedmont, who was being encouraged by many patriots to free Italy from foreign rule and to unite it under one single reign. (Photo 11)
It was also common for the lower social class of people to attend the opera. Many travelers throughout Italy were impressed by the fact that operatic pieces were being played and sung everywhere, even in churches! Hector Berlioz, who was traveling in Italy between 1831 and 1832, wrote: “I have often heard the overtures of the Barbiere di Siviglia, of Cenerentola and Otello [by Rossini]. Such pieces seemed to form the favorite repertoire of organists, who very pleasantly inserted them in the divine services.”57 The comment of Gaspare Spontini, as sent in an 1839 letter by Franz Liszt to the director of a magazine in Paris, is however of a very different note. The Italian musician was absolutely

. . . shocked, scandalized, as are all those who unite the religious sentiment to the artistic one, when listening, during the religious services, and during the celebrations of the holy mysteries, to only ridiculous and indecent theatrical reminiscences, full of anger in seeing the organ, this majestic voice of the cathedrals, making its large pipes resonate only with cabalettas in fashion.58

In such a musical climate it is very likely that the Italian organbuilders, in order to adapt operatic transcriptions for the organ in a more realistic way—possibly influenced by the effects introduced by the Austrian pianoforte, which was then in common use—may have begun to propose the introduction of Turkish instruments in their new organs, having been requested to do so by organists or even deciding to do so on their own.
References to such instruments start to appear around the second decade of the 19th century. Padre Davide da Bergamo59 (one of the most important figures in Italian organ romanticism), organist at S. Maria di Campagna in Piacenza, wrote in 1822 to the Serassi Brothers about the organ that he wanted them to build for him, for which he requested “. . . the tamburo reale” [the real drum], and in another letter he specified “as Tamburo reale I mean properly the drum of natural leather . . . .”60
One of the first applications of the entire device subsequently referred to as “Turkish Band”61 (consisting of bass drum, rolling drum, Chinese hat, and cymbals) by the Serassi Brothers is found in the organ of the Collegiate Church in Treviglio (Bergamo), built in 1816; however, there is evidence of the introduction of such a device in organs, even though possibly in part, around 1814: in the poem dedicated to the building of the organ of Revere (Mantova), the Catuba (bass drum)62 is mentioned. Around that time and for about 50 years following, many organs were built throughout Italy equipped with this fantastic effect, which is found almost exclusively in the romantic Italian organ. In fact, it is not at all present in Austria, it sporadically appears in France in a few organs around the end of the 18th century that no longer exist today (in this case, however, limited to the drum only), and in a couple of English organs, but the extensive use during the 19th century is a typically Italian phenomenon.
As mentioned above, opera was very much loved, and piano transcriptions of operas were very common. The treatise by Calvi63 features an entire chapter dedicated to the “Method to register several pieces transcribed for pianoforte,” in which he explains in fairly good detail how to use the stops to play an opera’s sinfonia, arias, or duets. This chapter follows a small paragraph dedicated to the “Method to imitate the arrival of a band,” specifying that by following the suggestions in reverse order one can also imitate the departure of the band. It is clear that the use of the Turkish band was adding realism to symphonies or other orchestral pieces. In fact, in the conclusion of chapter five, where the stops are described, one can read that this true drum can only be used for the playing of a few marches, and in some chordal inserts of harmony in symphonies and largo movements, “always limiting the hit according to the force [meaning volume] of the parts.” Immediately following, Calvi adds: “it is advisable not to use the Band too often and the Campanelli [Glockenspiel], particularly during the sacred functions.”64
The recommendations by Castelli, published thirty years later, are not much different. After stating that this effect is more in use in countryside churches and that the imitation “of the military and dance music is not fitting to the religious dignity of the sanctuary,” he suggests “not to make too frequent use of it” and limiting its use either to a final march, or to a finale using the fortissimo, or to insert it when the rituals represent “a religious rejoicing.”65
Castelli again provides a complete description of the mechanism and its use. He first explains that it is composed of the bass drum (or leather drum), the crash cymbals, sistro [Chinese hat], and a rolling drum [made with organ pipes], which is activated by a pedal similar to the one used for the tutti. He then describes a very imaginative use for this device:
By pushing down the pedal “gently and slowly” the sound of the rolling drum alone can be obtained (which can be used in the place of the one that he previously refers to as Tremolo, or even in tandem with it);
By hitting the pedal with a “sharp but light hit” the bass drum and the rolling drums can hardly be heard, but it is possible to obtain “the distinct sound of the cymbals and of the Chinese hat, which is useful in adding a special color to some brilliant passages even when piano.”
As far as this special effect is concerned, in the performance of romantic Italian organ literature, we can find several instances in which composers—unlike those of previous times, who were very restrained in giving suggestions—do write rather precise indications for the registration of their pieces. Normally the Turkish Band is referred to in the music as “Banda” or “B.da”, or even “Con Banda,” “B.a” or simply “B”.
In 1837, the Pistoia-born composer Luigi Gherardeschi called for the use of the Band in a section of his Gran Marcia per Organo, and the points for its use are indicated as “B”.66
Padre Davide da Bergamo uses the device with great rationality and parsimony; here are some examples.67
• In the series 15 pezzi di musica pel nuovo e magnifico organo di S. Maria di Campagna in Piacenza (15 pieces of music for the new and magnificent organ of S. Maria di Campagna in Piacenza), published in 1839, both at bar 153 of the Polonese68 in D major and at the beginning of the “Presto” section, he indicates “Con banda.”
• In a Sonata Marziale69 in F major, he indicates first “Banda” (measure 3) and then “B.a” (measures 7, 11, 15), subsequently indicating “F con banda,” five times in all within a rather long piece—by analyzing the piece, it seems there are other points at which to use it (for example, measure 87 and the Finale).
• In the third of a series of Versetti,70 a piece of slightly more than 50 measures, he requests the “Banda” to be used ten times! (Example 1)
• In a Suonata71 in B-flat major, he specifically requests “Con sistro Cinese” (with Chinese hat), then simply “Sistro,” three times in all (measures 8, 16, and 27). Evidently he refers to the use with “sharp but light hit” as described by Castelli in his book, which allows the activation of only one part of the Banda; the special effect is requested in its totality in a following section of the piece (mm. 45, 102). (Example 2, on page 24)
These few indications in almost 60 organ pieces show us that Padre Davide was convinced of the need to not abuse this effect, as indicated by Castelli. It is very likely, in fact, that Castelli was influenced by the indications of this ingenious composer, given P. Davide’s close contacts with the Serassi family, and consequently with Castelli himself.
In spite of the recommendations of various composers and writers to use restraint with such effects as the Banda, and to perform pieces in keeping with “the holiness of the site and the religious majesty with which the sacred services are to be accompanied,”72 a bit of everything was performed in Italian churches. A clear picture of what Italian organists played during the second half of the 19th century—besides the testimonials by Berlioz and Liszt as previously described—is offered by a list of “forbidden music,” published by the Catholic Church in 1884, which forbids in a church

even the smallest part or reminiscence of theatrical operas, of dance pieces of any kind such as Polka, Walzer, Mazurkas, Minuets, Rondo, Schottish, Varsoriennes, Quadriglias . . . National hymns, Popular, erotic or comic songs, Romanzas . . .73
This excessive freedom in the choice of repertoire, together with the new organbuilding ideas coming, once again, from across the Alps, produced towards the end of the 19th century a reaction against the shining sonorities of the romantic Italian organ, which led to the modification of many instruments by means of the suppression of reed stops and cornets, the reduction in number of the Ripieno ranks, and the dismantling of the most characteristic effects74 in favor of strings. This change produced a modification of the music being performed, which became surely more severe and solemn, but also more boring!

The Campanelli (Bells, Glockenspiel)
The Venetian organbuilder Gaetano Callido, between the 18th and 19th centuries, never failed to include, among the registrations suggested for his instruments, the one “ad imitazione dei campanelli” (“to imitate the Campanelli”), which could be obtained by registering the Principale over the entire keyboard compass, the Voce Umana and one Ripieno rank (the Vigesimanona) of ½′, and by playing “spiccato” or “arpeggiato nel basso.”75
Giovanni Morandi (1777–1856), a composer of the Marche region whose compositions were entirely written for the type of organ built by Gaetano Callido or, more generally, for the type of organ built in the late 18th-century Venetian style, also wrote a Rondò con imitazione dei Campanelli.
In various organs built from the end of 1700, however, the real Campanelli appear among the special effects, sometimes also called Gariglione (a term that comes from the Italianization of “Carillon”). It is a stop limited to the treble portion of the keyboard, and is made up of a series of tuned bells in the form of small bronze “cups,” featuring a very bright sound. (Photos 12, 13, and 14)
Back in 1589, Emilio de’ Cavalieri had a series of 36 bells made for him, which were likely connected to an organ, even though this is not absolutely certain. In such a case, the stop extension would have been much greater than the one in use between the 18th and 19th centuries: from A1 to A4 or from F#1 to F4, depending upon the keyboard’s compass.76
Between 1591 and 1600, we find another piece of evidence in the sonaglini (small bells) by Fulgenzi for the Orvieto organ,77 but it is only during the end of the 18th through nearly the entire 19th century that the Campanelli were included in new organs or added to existing instruments.
Luigi Gherardeschi from Pistoia used them in a section of the Gran Marcia per Organo of 1837, by adding the Gariglione (bells) together with the Cornet, to a registration formed of Principale basso, Bordone basso and Bordone soprano, Flauto, Tromba, and Decimino (13⁄5′).78
In his manual dealing with the Campa-nelli, Calvi states that “a good effect can be obtained by playing them with the Flauto in Ottava alone, and by accompanying them with Fagotto and Ottavino [2′ flute] with arpeggiato passages in the bass.” He suggests their use even in conjunction with the Cornetto. He also includes the possibility of their use in “mezzoforte and forte” movements, suggesting not to play chords without accompaniment.79
A few years later, Castelli included them in the specifications for his “middle size organ” and the “large size organ” (Massimo), among the three versions that he considers possible, but he does not talk about their use, as he had done for other effects or accessories.80 However, in the Prontuario di registrazione (registration instruction manual), he suggests three registrations that utilize them:
The first (to be used in staccato or puntato passages) includes the Campanelli, Traverse Flute, Octavin, Octave and Viola in the bass;
The second (for fast and virtuoso passages, to imitate a carillon) consists of Flute in XII, the Second Principal in the treble, and again the Octave and the Viola in the bass;
The third registration (for marches) includes the Tromba, Traverse Flute, Octavin, Fagotto and Octave in the bass.81

The Terza Mano (“Third Hand” or super coupler)
The “Third Hand” was an accessory that gained a great deal of popularity during the romantic Italian organbuilding period, and consists of a super coupler for the upper part of the keyboard. It was invented around 1816 by Giuseppe II Serassi (1750–1817), an ingenious organbuilder. The Quarta Mano (Fourth Hand) (the sub coupler in the first half of the keyboard)82 was invented along with it, but will not be dealt with here, since this device was much less common in the Italian organs of that period. (Photo 15) The Third Hand was highly successful, however, and it was adopted in new organs throughout Italy, as well as being added to existing instruments. It can be operated by a pedal, by a stop lever, or by both controls within the same organ. The most predictable and trivial use is surely that of utilizing it in octave passages, where, rather than going to the trouble of playing two notes at once, one can activate the device and simply play the lower note on the keyboard; it is quite obvious that, by doing so, speed and accuracy of playing increases.
Castelli, however, gives us a very detailed account of the less-obvious use for this device in a special chapter of his treatise.83 He suggests using it to reinforce the soprano line in theme repetitions, in order to create a crescendo effect, but he also states that it is effective even in piano passages. It is useful, he assures us, in making “more brilliant and marked” a passage that is written in a low tessitura. Furthermore, in the case of notes or chords held in the central part of the keyboard, it is possible to hit the corresponding pedal in a staccato manner, thereby underlining those notes or those chords.
Calvi, in 1833, stated that the Third Hand is very useful “in the ripienos, the crescendos, as well as in syncopated passages.”84 He also suggested a specific sequence of stops to imitate the “messa di voce”85: starting with the “Principale in the bass, and the Voce Umana alone,” going further by adding “. . . Principale primo and the Crescendo will be obtained, then with the Third Hand more forte will be obtained.”86 Calvi again suggested imitating the Clarinet by using the Traverse flute together with the Third Hand.87
Padre Davide da Bergamo, as in the case of the Band, limits the use of this device to specific instances:
• For crescendos (example: Suonata88 in B-flat major, bar 171), in which the section with the Third Hand precedes the forte;
• To slightly increase the volume without making stop changes in a piano section (example: Sinfonia89 in C, bars 110 and 212);
• To highlight a theme in its ripresa variata (example: Pastorale90 in A major, in the last section, Allegro, bar 192);
• To make a theme that is played in the middle section of the keyboard “more brilliant and marked,” as Castelli says (example: Sinfonia91 in D major, bar 234). (Example 3)
As with other effects, it is possible to record a very limited and careful use of the Third Hand by Padre Davide, who suggests its use only in the few examples shown and in an extremely limited number of other instances throughout the sixty pieces that I have analyzed.

The Combinazione Preparabile “Alla Lombarda” (Adjustable Combination in the Lombard Style)
Another invention, introduced by Andrea Luigi Serassi92 around 1776, gained great success: a mechanism by which a combination of stops could be prepared in advance, which Castelli called Tira-tutto preparato (pre-arranged tutti). It was later adopted by many organbuilders with the name Combinazione alla Lombarda (Combination in the Lombard style). This mechanism allows the organist to add a series of previously “prepared” (by the organist) stops to a registration. It is activated by a pedal protruding from the casework located at the right side of the pedalboard.
For this mechanism, Castelli again illustrated an original use, which was later exemplified in one of the Petrali compositions attached to his treatise (number 21). The more common use is that of adding a registration to another one to form a crescendo. Another, more interesting use is by means of small percussive taps of the pedal, for example on the weak beats of the measure, while chords are being held, to imitate the orchestral effect of the introduction of new instruments that start playing while other instruments are already playing tenuto harmonies.93
This is also a case where a careful analysis of the piece to be played, and the choice of performing it in orchestral style, can greatly help the player in utilizing the possibilities offered by instruments with the “Combinazione alla Lombarda.”

Conclusion
Through the centuries, the Italian organ, far from being limited in its expressive possibilities, was influenced by changes in musical taste and was in turn effective in influencing them. Even within the context of its rather simple tonal structure, by incorporating effects and accessories it has taken up new sounds and new dimensions. The cooperation between organbuilders and organists has never ceased to be fruitful for both, producing masterpieces of great quality and musical wisdom.
In many instances, for the performance of Italian organ music, performers fail to use simple expressive means that have been a part of the musical palette of Italian musicians since the Renaissance. I believe that an historically informed and philologically coherent performance can give the player, even within rigorous boundaries, many more expressive and varied performance possibilities than a quick and unscrupulous reading of a piece, based on superficial knowledge and arbitrary decisions.

Francesco Cera and Andrea Pinchi

Francesco Cera was born in Bologna, Italy. He studied organ and harpsichord with Luigi Ferdinando Tagliavini and later with Gustav Leonhardt at the Amsterdam Conservatory. Regarded as one of Italy’s leading early music specialists, he has performed as a soloist in international festivals and on historic organs throughout Europe. Cera has recorded harpsichord and organ works by 17th-century Italian composers (Rossi, Merula, Storace and Valente) for the Tactus label, to critical acclaim. The French label Tempéraments issued the anthology “Rome Baroque,” with music by Frescobaldi and Pasquini. Francesco Cera has recorded three CDs of Scarlatti’s sonatas (from a 1742 manuscript), and taken part in the performance of all the sonatas at the Festival in Ghent (Belgium). The ARTS label has recently issued his recordings of Bach’s French Suites and four Harpsichord Concertos (with I Barocchisti, Diego Fasolis, conductor). From 1991 to 1994, Cera was a member of the ensemble Il Giardino Armonico. He directs the Ensemble Arte Musica, with whom he performs an Italian repertory spanning the period of Gesualdo’s madrigals to 18th-century cantatas. He has led masterclasses and workshops at the Royal Academy of Music London, Académie d’Orgue de Fribourg, Accademia di Musica Italiana per Organo, the University of Illinois, Cornell University, Arizona State University, and Oberlin College. Since 2001 he has lived in Rome, where he is Honorary Inspector of Early Organs for Rome and the Lazio region. His website: www.francescocera.it.

Born into a family of organ builders, Andrea Pinchi learned the rudiments of the art of organ building as a child from his paternal grandfather, Libero Rino. After receiving a scientific degree in 1987, he officially joined the family business, refining his knowledge under the direction of his father, Guido, and participating in the construction of important organs, working especially on pipe design and pipemaking. From 2001–2003 he was managing director of Stinkens Italia Srl, a company that has made thousands of pipes worldwide, and especially for U.S. organbuilders, over the years. In 2001, with his sister Barbara, he founded the historic organ restoration firm Ars Organi, which has carried out restorations of great interest, such as those of the 1509 organ of Mastro Paolo Pietropaolo in the Chiesa Museo di San Francesco in Trevi (Umbria), the 1615 Antonino La Valle instrument in Santa Maria Assunta in Sclafani (Sicily), the 1759 Conrad Werle organ in San Giuseppe in Leonessa (Lazio), and currently, the two-manual 1769 Aloysius Galligani organ in the Chiesa del Suffragio in Foligno. He has considerable experience in the field of organology, thanks to the teaching and guidance of Dr. Oscar Mischiati, with whom he worked closely from 1981 to 2004 in his family’s restoration business. Pinchi supervised the cataloging of the organs in the diocese of Foligno for the Umbria region; he has published numerous articles on organology. He has participated in organbuilding meetings both in Italy and abroad; he is president of L’Associazione “Aloysius Galligani,” which deals with historic organs of the Umbria region. He is owner, with his siblings Barbara and Claudio, of Fratelli Pinchi , a company founded in 1930, which has built over 440 organs in Italy and other countries; among the most significant are those of the Duomo in Arezzo, Kusatzu Concert Hall in Japan, Tempio Don Bosco in Asti, and Padre Pio Basilica in the Renzo Piano-designed San Giovanni Rotondo—a four-manual, 100-rank mechanical action instrument. He has supervised the temperament and tuning of many historic organs for recordings made by Archiv-Deutsche Grammophon, Camerata Tokio, Discantica, Opus 111, Quadrivium and Tactus. He does design work both for the family firm and for foreign organ builders.

After more than thirty years and hundreds of instruments restored with the highest technical qualities, the restoration of historical organs in Italy still holds surprises and offers us opportunities for growth and knowledge. In the last few years, our view of the antique Italian organ has become even larger and more diversified, not simply in the general structure of the instruments, but mostly in the tonal concept adopted throughout Italy over the centuries by organbuilders.
In the church of Santa Lucia, in Serra San Quirico, an old village in the mountains near Ancona (Marche region), it was possible to discover a particularly rare instrument. It is an organ dated 1676, signed by Giuseppe Testa, a famous organbuilder from Rome. Scholars knew about the existence of such an organ, but since no evident signature was ever found, its attribution was still uncertain, also considering that it was in quite a different style from that which defined the organs made in the Marche region.

Background of the instrument
During the restoration process, conducted by the Ars Organi company, located in Foligno and owned by Andrea and Barbara Pinchi, an inscription on the top of a languid was found: “Io Giuseppe Testa Romano feci in Roma Anno 1676” (“I, Giuseppe Testa, Roman, made this in Rome in the year 1676”). Giuseppe Testa is surely to be considered the most important organbuilder in Rome in the mid-17th century; he maintained the organs in the basilicas of San Pietro and Santa Maria Maggiore, and built numerous organs now placed in the churches of Rome. Unfortunately, many of the instruments he built that are still extant have been greatly modified throughout the centuries; thus, there is little historical evidence of his work. This is why the organ in San Quirico is of such extraordinary importance: an organ by Giuseppe Testa that was quite well preserved.
Most of the elements are still original: 95% of the pipes, the keyboard and pedalboard, casework, windchest, even the stool for the organist! Particularly beautiful are the three central pipes of the façade, modeled in a spiral, typical of the Roman school. In the 19th century, drawknobs and bellows had been changed and were rebuilt during the recent restoration job, modeled after originals from the Roman School of the period. The pipes had suffered some bad nicking, but many pipes were still intact in the mouths and helped furnish the model for the general voicing of the instrument. The reason this instrument is about 200 km from Rome is that the Marche region, in the 17th century, belonged to the Papal States, and the reason for the choice of Santa Lucia in San Quirico is probably due to the fact that this village is on the way to the Sanctuary of Loreto.

Stoplist and sonorities
The stoplist of the Testa organ presents different elements of originality. There are two 8′ Principals, of which the second is of sweeter tone; the first inner pipes were made in metal, and so they have been rebuilt this way. There are two flutes, one 22⁄3′ and the other 2′ (called by the builder Flautino), instead of the more common 4′ one. A 16′ Controbassi in spectacular chestnut wood, from C1 to C2, is coupled to the keyboard (the pedalboard is simply linked to the keys without an independent stop). The rarest stop is the 8′ Voce Umana, from F2. This well-known Italian stop, designed to beat in combination with the Principal, was widely used in northern Italy since around 1550, but it had never been used in Rome nor in other parts of central Italy until the beginning of the 18th century (apparently in Rome, Frescobaldi did not have the Voce Umana for his Toccate per l’elevazione). Therefore, this stop in the organ of San Quirico is the oldest that we know of among all the instruments built in Rome in the 17th century, and perhaps suggests that this stop was known by the organists of the Eternal City (we hope this hypothesis will be confirmed by other discoveries in the future). The effect of the drum is interesting and unusual; activated by the last pedal in the pedalboard, without its own pipes, it acts on the D1 and F1 notes of the keyboard.
The organ by Giuseppe Testa in Serra San Quirico offers us the possibility of finally hearing the tonal concept of this very important organbuilder from Rome, whose personality and craftsmanship are well evident not simply in the manufacture of the pipes and the mechanical parts, made with great knowledge, but also in the sound itself. At the time of the organ’s construction, Rome was an important center for organ music; it was dominated by Bernardo Pasquini, follower of the master Girolamo Frescobaldi. Many organists from Germany came to Rome to learn the latest organ style.
The measurements and the proportions of the pipes are such that their effect can be well appreciated by the ear. The sound is quite clear, bright and full of harmonics, even if not completely transparent but matched with a good fundamental and with generous speech. The main Principal is, along with the 22⁄3′ Flute, the stop with more fundamental, though it maintains a light character. The second Principal is sweeter than the main one but not dark. The 4′ Octave marks a tonal separation from the main Principal, because of its narrower scaling; that is why it is more penetrating and clear. The five ripieno ranks follow the same style of the 4′ Octave, and their sound is similar to strings, very open and brilliant.
The Voce Umana has a sound that matches better with the main Principal than with the second. The 22⁄3′ Flute is among the most surprising stops of the organ: its sound is strong, round and projects well in the church. It is only a hypothesis that the size of the other 2′ Flute recalls the Roman organs of 16′ that had 2′ and 11⁄3′ flutes. Its timbre is different from the 22⁄3′ one, less round, but does not lack sound. The 16′ Controbassi is also very clear and does not have a booming effect in the acoustic.
The restoration by Ars Organi has had the delicate responsibility to re-establish the original pitch with the best approximation possible, and to recreate the original sound of the instrument through an in-depth study and patient work of voicing, achieving surprising and very convincing results. This organ allows us to discover the sound conceived for the organ works of Bernardo Pasquini, and to execute with great taste all the literature of the 17th-century Italian masters as well as the German composers who took their inspiration while in Rome.

Translation by Zoila Donati

The first time I saw the organ in the magnificent church of Santa Lucia, in 1987, I was aware that I was looking at an organ of rare beauty belonging to the Roman School, but I had no idea I was looking at the last masterpiece produced and signed by Giuseppe Maria Testa!
Obviously, whenever a restoration job is undertaken, one dreams of making an extraordinary discovery, like a hidden handwritten paper inside the windchest, or under the first key—or under the languid of the first front pipe! All of this, with other little discoveries, has allowed us to reconstruct the original look of the instrument.
The restoration work began in 1998 and ended in 2007. At the end of this job we produced an in-depth publication. I will later highlight the most important aspects regarding the tonal material.
Throughout three centuries the instrument has undergone numerous interventions, some of which have been particularly serious, such as converting the instrument to equal temperament, raising the pitch to 426 Hz at 11°C, tampering with the drawknobs, the modifications of the pedal windchest and the substitution of the original bellows. However, the original pipes were all present, even if they were seriously altered by the falling of the rackboard and by interventions made with little attention. The tops of the front pipes and of the internal ones had been cut and scrolled. Some feet of the façade pipes had dents that could easily be seen, and some toeholes had been altered and closed. A substantial number of factory-made pipes had been used to fill in or replace a few original pipes, which were considered impossible to save.
From a tonal standpoint, everything seemed to coincide with the original model, although a lot of the pipes in the ranks had been mixed, and not all of them played where they were supposed to. Even the pipes of the 2′ Flautino had been used in the 22⁄3′ Flauto in XII, and in their place in the 19th century someone had put a 4′ Ottavino. The first four pipes of the Principale Primo (front), originally made in metal, had been replaced in the 1800s with pipes made of fir. The 16′ Controbassi stop in chestnut, originally stopped, had been opened and doubled in its length with fir.
The survey has highlighted all the elements of the primary nucleus, then they have been rearranged according to the original numbers. By doing this, all the pipes that had been moved started to play, as they should have, consistently with the right balance between diameters and lengths. All operations providing the correct rearrangement have also restored uniformity of the thickness of the pipe metal, especially in the principals: very thin in the Principale Primo and Voce Umana, and much more robust in the Principale Secondo. The thicknesses of the metal of the Flauto in XII are much more substantial and they grow proportionally towards the high notes.
The bevel of the languids varies greatly according to the stops. The lab analysis produced the following results: front pipes 97.9% tin; inner pipes 98.4% lead. Following the preliminary phase, the pipes have all been cleaned and restored to their original conditions. During the last intervention the instrument had been retuned to 426 Hz at 11°C, and the temperament modified to equal, which made it necessary to lengthen all the pipes.
Once we collected all the non-original pipes, we proceeded building 154 pipes out of 471 (33%) using the same models, alloy and measurements of the originals. The pitch has been restored at 415.7 Hz at 14°C, humidity at 52%, while keeping in mind the pipes of the 16′ Controbassi, which maintained traces of the plugs inside, and the original metal pipes, which preserved unaltered voicing and length of the bodies. The temperament is again meantone ¼ comma.
The characteristics of the nicking are rather common to all the stops and count on average seven nicks per languid. For the Principale I, Principale II, the Ottava and the Voce Umana, the nicking is done all the way to the pipes of ½′.
The greatly varied bevel of the languids of the different stops and the differentiated scaling speaks by itself to the knowledge of Giuseppe Testa, who knew how to design the instruments he made with incredible taste and attention. The principals are differentiated in diameter and metal thickness. The ripieno ranks present a complex and elaborate mix of diameters that are narrow for the high notes and more generous in the low notes.
The Flauto in XII was thought out and realized with very clear principles, with diameters that start out rather narrow to widen later towards mid-keyboard, doing the same thing with increasing pipe metal thickness. This is the physical rendering of a wooden recorder, with its dynamic characteristics. All operations have been supervised and directed by the Italian authorities appointed to supervise all restorations in the Marche region, in this case Professor Maria Claudia Caldari and Maestro Mauro Ferrante.
Also part of this restoration were Andrea and Barbara Pinchi, Ivan Dumitrak, Marco Dominici. Assistant for voicing: Francesco Cera. Historical-philological research: M° Mauro Ferrante, Ispettore Onorario della Soprintendenza delle Marche; Prof. Paolo Peretti, Organologo e Musicologo, Conservatorio di Bari.

Tradition and Development

by Francesco Ruffatti

A concert by Luigi Ferdinando Tagliavini and Gustav Leonhardt at the Basilica of San Petronio in Bologna, held on October 27, 2000, provided the inspiration for  writing an article on the historical Italian organ, its tradition and development. My goal is to give a panoramic view of the subject, and anyone knows that when looking at a panoramic view much of the detail is lost. Still, such an attempt is worth carrying out because some general guidelines can in any case be drawn. To do so, it is necessary to go back a number of centuries and try to understand the original role of the organ in the musical world of Italian churches.

 

The Basilica of San Petronio is no ordinary place from the standpoint of organbuilding history. It enjoys the presence of two unique instruments: the oldest Italian organ in existence, built by Lorenzo da Prato between 1471 and 1475, roughly 20 years prior to the discovery of America by Columbus,1 and a later organ, built by Baldassarre Malamini in 1596. The instruments are located face to face in the area traditionally reserved for the choristers, behind the high altar.

The program notes for the Tagliavini-Leonhardt concert, written by Marc Vanscheevwijck, well explain the use for which organs of medieval and renaissance times were intended:

Alternatim performance practice, i.e., the performance of liturgical pieces alternating contrasting musical forces in the various versets of the sacred texts, originates in the old antiphonal singing of psalms of the first centuries A.D. In responsorial music a soloist or a small group of singers alternated with the larger choir. Sometimes they alternated plainchant with polyphonic settings of the text. Probably as early as the organ began to be used in church, the organist already improvised "versets," alternating with the choir singing the counter versets in Gregorian chant. Obviously, the schola never repeated the texts of the versets played by the organist, who improvised (and later composed) on the relative Gregorian melodies. The earliest source of such a practice is the Faenza Codex, compiled c.1420. During the following century this alternatim practice spread throughout Italy. Many alternatim settings, particularly of the mass proper, have been preserved, some of the most famous of which were composed by Girolamo Cavazzoni, Claudio Merulo, Andrea Gabrieli, and (in the 17th century) the Fiori Musicali of Girolamo Frescobaldi.2

 

Two aspects immediately come to mind:

1. The organ location, which for effective responsorial use had to be near the choir and not necessarily in a favorable position for the congregation,

2. A tonal structure suitable for dialogue with a small group of singers.

There was no need for a sound big enough to accompany the choir, simply because the organ was intended as a soloist. And accompanying the congregation was certainly not in the agenda, since people did not sing during liturgy in Italian Catholic churches until very recently.3

What effect did all of this have on the sound? Since power was not the issue, early Italian organbuilders developed their talents in other areas, and tonal quality became the priority. They created relatively small instruments, mostly with only one manual, with gentle, beautifully voiced stops. Wind pressures were in most cases quite low, down to 42-45 mm. at the water column, and the voicing techniques as well as the tonal design in general reflected such an approach.

Listening to music by Antegnati (also a famous Italian organbuilder), Segni, Veggio, Gabrieli and others performed on the beautiful organs of San Petronio gave me and the entire audience (a few hundred people all gathered in the large space behind the high altar, to be able to best hear the organs) a good perspective of the musical experience which was originally expected from such instruments.

It is my belief that the original DNA of ancient Italian pipe organs, as defined by their original use in the liturgy, played a decisive role in the subsequent evolution of the instruments. This was due to a strong sense of tradition among the vast majority of builders and to their reluctance to introduce changes to a practice which was considered successful. Examples to the contrary do exist, but any effort of generalizing, or extracting general rules from a complex reality, always ends up sacrificing notable exceptions.

In post-Renaissance times, organ use became widespread. All Italian churches had at least one organ and often one or two Positivo4  instruments in addition to the main organ. And a very significant change took place: in addition to being used as a solo instrument for improvisations and for the performance of written music, the organ also became an accompanimental instrument for the choir. Its location within the building also changed in most cases, taking into greater consideration the congregation as the beneficiary of musical performances: the preferred location for new instruments became a balcony facing the nave, which is still considered by many to be the ideal location for the best possible diffusion of sound within a building. Naturally, broader tonal resources had to be made available in order to accommodate this new function, but this did not cause a significant change in the original voicing practices. In other words, more stops were introduced and a Pedal division was added (normally consisting of one or two stops), but the basic tonal structure remained the same and no major changes took place in the sound: still low pressures and gentle voicing. After all, organs still did not need to be big or powerful, because they were not intended to support an entire congregation, just a choir.5

A further, major evolution took place as a result of the greater demands by the repertoire of the Romantic period. A great number of new stops were introduced: reeds of various types, more flutes, strings, even percussion: drums, cymbals, bells and the like. The organs built by the Serassi family of Bergamo towards the end of the eighteenth century and during the following century are a good example of the romantic Italian organ. The occupation of Bergamo by the troops of Napoleon (1796-1813) and subsequently by the Austrians (1814-1859) influenced organbuilding practices by introducing new musical models and, as a consequence, by contributing to the development of new devices and new sounds that would improve the performance of the music inspired by the teaching of Simon Mayr (1763-1845), by his pupil Gaetano Donizetti (1797-1848) and by Gioacchino Rossini.6 The famous composer Felice Moretti (also known as Father Davide da Bergamo), a Franciscan monk and a family friend of the Serassi, composed music that was deeply influenced by opera. Also, Giuseppe II Serassi, the most innovative member of the family, introduced new devices aimed at facilitating the dynamic control of sound: the third hand, or mechanical super coupler, the fourth hand, or sub coupler, the expression shades, pedals for pre-set combinations of stops, an easier system for the coupling of the manuals (by means of a pedal and no longer by the sliding of the upper manual into position), settable combinations of stops, and the Tiratutti or Tutti for the Ripieno ranks.7

In spite of all of this, the ancient core of the instrument and the basic tonal concept behind it remained virtually unchanged for a good part of the nineteenth century. Low wind pressures were still the rule, as well as unforced voicing, fairly open pipe toes, and few nicks at the languids. As a consequence,   there was a broad harmonic development in the sound, allowing a very effective use of each stop in combination with others and forming an ensemble of rare cohesion and beauty. Pressures of sometimes less than 50 mm. at the water column naturally presented a real challenge, particularly for the voicing of reed stops, but this had the effect of encouraging builders to find original design and voicing methods to overcome the difficulties.8

At this point, it is necessary to define the tonal core of the organ which I have indicated as an element of continuity in Italian organbuilding throughout the centuries. Its main component is the Ripieno. The term does not translate to Mixture, but rather it defines a series of individual Principal scaled ranks of pipes at various pitches, creating a system of sounds at harmonic intervals, normally beginning with 8' pitch as the foundation of the manual.

The composition of a typical Ripieno with its traditional nomenclature follows:

Principale (I) 8'

Ottava (VIII) 4'

Decimaquinta (XV) 2'

Decimanona (XIX) 11/3'

Vigesima seconda (XXII) 1'

Vigesima sesta (XXVI) 2/3'

Vigesima nona (XXIX) 1/2'

Trigesima terza (XXXIII) 1/3'

Trigesima sesta (XXXVI) 1/4'

And occasionally:

Quadragesima (XL) 1/6'

Quadragesima Terza (XLIII) 1/8'

The highest pitch in the entire Ripieno is in most cases the note C at 1/8'. Beyond this limit a ritornello or break begins with pipes double the length, or one full octave lower in pitch.9

Table 1 is intended to give a clear and comprehensive idea of the tonal composition of the Ripieno. The method I am utilizing is unconventional and it consists of identifying each pipe by a number corresponding to its place in an ideal succession of notes starting with number 1 as low C of the 8' Principal. Low C at 4' will consequently be numbered as 13, low C at 2' will be numbered as 25 and so on. The highest pitch pipe in the Ripieno will be number 73, corresponding to the pitch limit of 1/8'. Once a rank reaches note number 73 it will break back and start a ritornello with note C#62 (or one full octave lower). To simplify matters, I am showing the first octave as complete (12 notes). The most common arrangement in Italian historical organs calls for a short first octave (8 notes, with C#, D#, F# and G# missing). Notes are identified by octave number, according to the Italian system, by which C1 corresponds to note C of the first octave, F3 to note F of the third octave, and so on. The chosen compass for our example is of 49 keys, C1 to C5. This system, by numbers rather than by footage, is intended to provide a more immediate idea of the repetition of equal size pipes throughout the compass for the entire Ripieno. Equal number means equal size pipe.

The conventional method is shown in Table 2. The Ripieno here is comparable, in pure terms of number of pipes, to a Principal chorus with 8', 4' and 2' stops plus a six-rank mixture. But by looking at Table 2 one can immediately appreciate the vast difference from such an arrangement. At note C#2 the first doubling or double pitch appears: pipes from the 1/2' rank (XXIX) and 1/4' rank (XXXVI) become of identical size. Consequently, between notes C#2 and F2 the tonal effect is not that of a six-rank mixture but rather of a five-rank mixture with one of the ranks doubled. This aspect becomes more and more prominent as we move up the keyboard, to the point that at note C#4 (key number 38) with all ranks from Decimaquinta (2') up drawn, only two pitches can be heard: 2', repeated 4 times, and 11/3', repeated three times. As one can easily appreciate, such tonal structure cannot be compared with that of a Mixture, or Fourniture or any other multiple-rank stop designed as a single entity. The Ripieno is simply different. It is conceived as a sum of individual ranks at different pitches, each separately usable in combinations with any other rank and all usable at once as a pleno.10

Obviously, this feature provides a great deal of flexibility in the tonal palette. From an organbuilder"s practical standpoint, it has two effects:

1. It forces the voicer to be extremely scrupulous as to the tonal balance, regulation and speech adjustment of each pipe even in the highest pitched ranks, since each can be separately used;

2. It makes tuning more difficult, due to the drawing effect on the equal pitched pipes when they play together. Only a tuner who knows how to deal with such a problem can obtain a stable tuning of the Ripieno.11

Tuning with double pitches was nothing new to ancient builders. In fact, pre-Renaissance and Renaissance organs, in Italy as well as in other European countries, often had double or even triple notes of equal length in the treble of the Principal, the Octave and sometimes the Fifteenth, to enhance the singing qualities of the instrument in the treble. This practice strangely survived, in some areas of Italy, all the way to the beginning of the 19th century. This proves that the difficulties connected with the tuning of multiple equal-pitched pipes never bothered Italian organbuilders too much.12

Other traditional stops forming the original core of the historical Italian organ include the following:

Flauto in Ottava (4'), normally tapered or cylindrical, sometimes stopped

Flauto in Decimaquinta (2') in the earlier instruments

Flauto in Duodecima (22/3')

The Terzino, or Tierce flute (13/5') was later added and, in the nineteenth century, the Flauto Traverso or Fluta (8', normally in the treble only).

Early strings appeared in the eighteenth century, at 4' in the bass and occasionally over the entire compass, but such stops were vastly different from what we think of as a string today. They had no ears, no beards, no nicks at the languids. These characteristics, combined with a very narrow scale, contributed to produce a sound with a very prominent transient at the attach and a cutting sustained tone, strongly imitative of early string instruments.

The Voce Umana or Fiffaro, a Principal-scaled stop at 8' pitch (treble only) was also used in the Renaissance and became increasingly more common in the Baroque and later periods. Its pipes were normally tuned sharp against the 8' Principal, except in the Venetian tradition and among a few builders in the south of Italy, where flat tuning was preferred.

The above description, as I have said earlier, represents a simplification of a much more complicated subject, and many examples exist that do not follow the rule.13 Also, all of those who are familiar with ancient Italian organs will agree that the tonal experience that comes from a Callido or a Nacchini organ is vastly different from that of an Agati or a Catarinozzi. They were expressions of very different artistic environments and the builders were very faithful to their own local traditions.

What happened in nineteenth-century Italian organbuilding is worth investigating a bit more closely. Early signs of rejection of the Italian romantic organ appeared. In 1824 the Cardinal Vicar of Rome promulgated an edict stating: "Organists may not play on the organ music written for theater, or with profane character, but only music that can encourage meditation and devotion . . . "14 Still, many of the major builders in the north, as well as many in other parts of the country, continued in their tradition of building instruments without changing their style.15 But at some point, foreign influence became a strong factor16 and the "new inventions," the Barker lever first and then pneumatic and electric action, came into the picture.17 Pneumatic action in particular and the new sounds, such as the "modern strings" and harmonic stops demanded higher wind pressures, and the organ sound became stronger and aggressive. But, as we all know, pneumatic action represented only a relatively short transition period in organbuilding history, and a further evolution of the instrument was soon marked in the following century by a perfected electric action and by the rediscovery, in the mid 1960s, of tracker action. This movement was immediately promoted by some of the major Italian builders18 and it became stronger and stronger over the years. The neoclassical instrument was created, based on mechanical action and on the re-discovery of the traditional sounds and voicing techniques. But, as it is often the case, the intent was not that of copying the past but rather of preserving the best of tradition within a new context which was calling for a new use of the organ: the support of congregational singing.

One may get the impression that it is impossible to extract a general trend from this entire process of evolution. Still, I believe that one common denominator can be found: the unforced, pleasing singing quality that has survived unchanged for over five centuries, and which effectively represents, in musical form, the character of the Italian language.

                  2.              Concerning earlier use of the organ in western world churches, see Peter Williams (Duke University, Durham, NC) in his essay "The origin of the Christian organ with some particular reference to Italy," Acts of the International Symposium on "I Serassi--L"arte organaria fra sette e ottocento," Ed. Carrara, Bergamo, 1999, p. 12. Referring to the early Middle Ages, he writes: "I don"t know any evidence that organs were brought into church in order to accompany singing--whether it was the celebrant singing at mass, the lay people responding with their own acclamations, or the monks chanting their daily office in private or in public. All that one can be certain about is that organs were there to provide sound, and whatever later music historians may have assumed, it is seldom if ever clear what kind of sound they made, or for what purpose and at what point they made it. Only from the thirteenth century onwards the picture is clear . . ."

                  3.              While the practice of congregational singing at celebrations in Italian churches may have had its first examples at the end of the nineteenth century, it was during the Second Vatican Council that this practice was actually encouraged.

                  4.              A Positivo can be described as a smaller size "cabinet" organ, self-contained, whose casework is normally divided in two sections: the lower case, containing the bellows (normally two multi-fold hinged bellows activated by levers), and the upper case, which sits on top and which holds the keyboard, the windchest and pipes. It was almost invariably built without independent pedal stops,  and its pedalboard, when present, consisted normally of one short octave, whose keys were connected to the corresponding keys of the first octave at the manual by means of strings or wires. Although easily movable (sometimes large handles on the sides of the two sections of the case indicate this possibility), it is different from a Portativo, an even smaller instrument whose primary function was that of providing music during outdoor processions.

                  5.              Larger instruments are not unknown to historical Italian organbuilding. I will mention two examples of rare complexity:

a.) The instrument at the church of San Nicolo L"Arena in Catania, by Donato del Piano (1698-1785), with a total of five keyboards, divided between three consoles attached to the case (1 manual - 3 manuals - 1 manual) with the larger console in the center and one pedalboard for the center console, plus a separate small automatic pipe instrument activated by a rotating drum. This enormous, beautiful instrument, now in a poor state of disrepair (among other things, the pipes have all been removed and stored), includes pipework of extremely unusual shape.

b.) The great organ at the Church of the Cavalieri di S. Stefano in Pisa, built between 1733 and 1738 by Azzolino Bernardino della Ciaia (1671-1755) with the help of other organbuilders from different parts of Italy, with four manuals plus a fifth manual activating a harpsichord. This organ was later converted into a pneumatic instrument and subsequently electrified. Only a portion of the original pipework survives.

                  6.              See Luigi Ferdinando Tagliavini, "Le risorse dell"organo Serassiano e il loro sfruttamento nella prassi organistica dell"epoca," in Acts of the International Symposium on "I Serassi--L"arte organaria fra sette e ottocento", Ed. Carrara, Bergamo, 1999, pp. 80-84.

                  7.              See Giosue Berbenni, Acts of the International Symposium on "I Serassi--L"arte organaria fra sette e ottocento," Ed. Carrara, Bergamo, 1999, pp. 22-24.

                  8.              The lower the wind pressure, the thinner the tongues must be to obtain promptness of speech. But thin tongues also produce undesirable side effects, notably:  a) A thinner timbre in general, with greater development of overtones and less fundamental; b) Uncontrollable sound at the bass register, where any reed naturally tends to become louder; c) Very weak trebles. To overcome these problems, a series of interesting methods were developed. I will mention a few:

a.) Wide and deep shallots to increase the volume of air excited by the tongue, with the effect of increasing the prominence of the fundamental in the tone;

b.) Double or even triple tongues at the low register, to control volume, timbre and stability;

c.) Variable tongue thickness at the treble, with the filing of the tip to obtain promptness while retaining a good volume of sound.

For a more complete description of voicing methods on low pressure reeds, with specific reference to the reeds of Serassi organs, see Francesco Ruffatti in "I registri ad ancia negli organi Serassi," Acts of the International Symposium on "I Serassi--L"arte organaria fra sette e ottocento," Ed. Carrara, Bergamo, 1999 pp. 144-150.

                  9.              When the lowest pitched stop on the manual is the Principal 16' the nomenclature remains the same, although all stops start one octave lower in pitch. The stoplist becomes:

Principale (16')

Ottava (8')

Decimaquinta (4')

Decimanona (22/3')

and so on. In essence, the organ is still seen as based on the 8' Principal, with the extension of a counter octave towards the bass (see my article on Gaetano Callido, December, 1999 issue of The Diapason, p. 17, Note 8).

                  10.           Luigi Ferdinando Tagliavini in his article "Il ripieno," L"organo, Year 1, No. 2, July-December, 1960, Ed. Patron, Bologna, points out the difference between the Italian Ripieno and the northern European mixtures as follows:

"a) The classical Italian ripieno is divided into its constitutive elements, corresponding to separate stops, while the foreign mixtures, starting from a certain pitch (from 4', from 22/3', from 2', from 11/3' etc.) are condensed into one stop;

b) Both in the ripieno and in the northern mixtures a gradual "compression" towards the treble takes place, a compression which is more limited in the German and northern European organ, greater in the Italian organ. In fact a ripieno will have a "compressed" extension in the treble, reduced from 8' to 2', while in the Mixtur-Scharf scheme the treble is extended between 8' and 1';

c) The "masking" of the jumps produced by the breaks is done differently in Italy from abroad; in Italy, by the division of breaks into two different points, one for the octave stops and one for the quint stops; abroad by the partial or complete substitution of the break in quint and fourth with the one in octave.

The northern European mixtures, through a particular interpretation of the break and without any fear of going beyond the pitch limits in the bass and the treble as imposed by the Italian ripieno, tend to make the tonal "density" more uniform, by reducing the difference between the tonal richness of the bass and the treble. Part of such uniformity is sacrificed by the Italian organbuilder in favor of tonal beauty. This is why the use of the Italian ripieno is mostly chordal and for toccatas, while the northern European organum plenum, especially the German, can also perform a polyphonic role."

In c) Tagliavini refers to alternation of quint and unison breaks within the same rank in all ranks of the mixture.

The pitch limit of northern European mixtures and related stops is often C at 1/16', close to the limit of human hearing, one full octave higher than the Ripieno and this factor alone determines a dramatic difference in the sound from the Ripieno.

                  11.           Drawing is an acoustical phenomena by which the sound of a pipe is drawn or pulled into tune by the sound of a second pipe which is playing an interval close to being pure or in tune. This effect is stronger between unison pipes; when tuning the second pipe to the first, its sound will slide into tune as soon as its frequency approaches that of the first pipe, but before it actually reaches the same value, thus determining an apparent tuning condition. Adding a third pipe and trying to tune it to the two previous sounds becomes impossible if the first two pipes are in a status of apparent unison, because each of the two sounds will react to the third pipe differently, according to their real frequency value. The difficulties increase exponentially from note C#4 up in the example shown, where two groups of 4 and 3 equal size pipes respectively play at once. The procedure to tune the Ripieno is consequently different and definitely more complicated than that of a regular mixture stop, as it must take into account the drawing of equal length pipes.

                  12.           I am here mentioning two organs, built in Tuscany by the Paoli family of Campi Bisenzio at the beginning of the 19th century, both restored by Fratelli Ruffatti in recent years:

a.) the organ in the Church of S. Francesco in Pontassieve, near Florence, built by Giacobbe Paoli, which includes doublings at the Principale starting with note Bb3, at the Ottava from note F3 and at the Decimaquinta also from note F3;

b.) the organ built by Michelangelo Paoli in the Basilica of S. Maria, Impruneta - Firenze, utilizing the pipes of a previous instrument by Bernardo d"Argenta, 1535, which has doublings at the Principale starting from note F#3, at the Ottava from note B3 and at the Decimaquinta from C4. Having re-built the windchest entirely, the builder could have easily eliminated the doublings had he not believed in the validity of such tonal approach.

                  13.           As an example, Sicilian organs in the 18th century were often built with multiple Ripieno ranks activated by a single stop control.

                  14.           See "La riforma dell"Organo Italiano" by Baggiani, Picchi, Tarrini, Ed. Pacini, Ospedaletto (Pisa), 1990, pp. 9-10.

                  15.           The largest instrument built by the Serassi family, the "Organum maximum" with three keyboards and over three thousand pipes, was built in the romantic style as late as in 1882. This instrument was restored by Fratelli Ruffatti between 1983 and 1985. It includes many of the effects which were rejected by liturgists, such as the drum, a bell and other percussion.

                  16.           Ferdinando Casamorata (1807-1881), musician and music scholar, introduced the work of Cavaillé-Coll to the Italian musical scene by making public the work of J. A. De La Fage "Orgue de l"Église Royale de Saint Dénis, construit par MM Cavaillé-Coll père et fils, Facteur d"orgues du Roi." Rapport. II edition, Paris, 1846. See "La riforma dell"Organo Italiano" by Baggiani, Picchi, Tarrini, Ed. Pacini, Ospedaletto (Pisa), 1990, p. 12. He gave explanations and favorable comments on some of the most remarkable characteristics of the instrument, notably the variety of wind pressures, the Barker lever, the "strength" of the upper registers, especially the reed stops, etc., and presenting them as valuable innovations worth imitating.

                  17.           An important role in this process was played by George William Trice (1848-1920), a British merchant who became an organbuilder and established a factory in Italy. He built the first electric action organ in 1888 for the Church of S. Andrea, Genoa. Other notable instruments followed, among which the three-manual instrument for the Church of the Immaculate Conception in Genoa, inaugurated in 1890 with concerts by Alexander Guilmant and Filippo Capocci.

18.               

Tamburini and Ruffatti were the first major Italian companies, in the early 1960s, to resume building mechanical action instruments.

 

Francesco Ruffatti has been a partner since 1968 of Fratelli Ruffatti, builders and restorers of pipe organs, in Padova, Italy. Besides being the tonal director of the firm, he is actively involved in the research on historical Italian organs and the supervision of the many historical restorations performed by the firm.

by Francesco Ruffatti

One of the most famous organbuilding "schools" in Italy was founded in Venice during the first part of the eighteenth century by Pietro Nacchini, a monk from Dalmatia.1 He established a factory and built over 300 organs mainly for the territories of the Republic of Venice,2 and for the Vatican State, which at the time comprised the largest portion of central Italy.  Although his designated successor was Francesco Dacci, with no doubt his most famous pupil was Gaetano Callido, born in Este, near Padova, who established his own organ factory in Venice and built well over 430 organs during his lifetime,3 some of which were for very distant countries.4

In manufacturing his instruments Callido basically followed the style of Nacchini, with only a few changes, both from the standpoint of tonal composition and type of construction. He conceived an organ as a one-manual instrument, with a limited pedal division. This is confirmed by the fact that in the original list of his works5 the relatively few two-manual instruments were designated as "double organs" and were given two consecutive opus numbers.

Callido's organs were by no means all alike, but their size was dependent upon the presence or absence of certain stops, all chosen among a limited pallet of stops from which the builder never departed.6 By giving the tonal composition of the Great division of the largest organ by Gaetano Callido, built for the Cathedral of Feltre,7 a good picture of his "selection" of organ stops is given.

The first part of the list includes all Principal-scaled ranks that form the "Ripieno". The stops can be used separately in various combinations or all together, collectively activated by a "Tiratutti" consisting of a rotating handle placed on top of the corresponding stop knobs.

Principale                (8')8 almost invariably divided, bass and treble

Ottava  (4')

Quinta Decima                        (XV - 2')

Decima Nona                           (XIX - 11/3')

Vigesima Seconda             (XXII - 1')

Vigesima Sesta                       (XXVI - 2/3')

Vigesima Nona                       (XXIX - 1/2')

Trigesima Terza                    (XXXIII - 1/3')

Trigesima Sesta                     (XXXVI - 1/4')

The last two ranks are often missing in the smaller instruments and are of full compass only in the larger organs, being normally limited to one or two octaves in the bass. The reason for limiting their compass is quite simple: since the highest pitched pipe in the ripieno of a Callido organ is C at 1/8', all ranks break back by one octave once they reach this limit. By doing so the "mixture" composition appears as in Table 1 (as an example I am considering a four-octave keyboard compass, C1 to C5).9

With this configuration, which is common to the majority of Italian historical organs (although the "breaking-back" points may vary at times), a number of pitch duplications are present from mid-keyboard up, to the point that, starting at F#4, only two different pitches are present while playing five pipes. In order not to extend the duplication of pitches towards the lower register and to avoid increasing the number of duplications at the treble, Callido normally ended the XXXIII and XXXVI ranks at the point where they would start breaking back (at F2 and C2 respectively) or further up the scale only by a few notes.

The "registri da concerto" or "consort" stops, as Callido called them, follow. First the flute scaled stops:

Flauto in Ottava (Flute in VIII - 4') often, but not always, divided, bass and treble. Normally built as a tapered flute, it is also found in the form of a metal stopped flute (with stoppers or caps made of leather-coated cork and inserted into the resonators of the pipes) or even as metal chimney flutes, with soldered-on caps.10

Flauto in Duodecima (Flute in XII - 22/3'), normally not divided in bass and treble (but it is divided for example in the Feltre organ). It was normally built as a tapered flute, although some examples of stopped pipes at the lower register and tapered at the treble do exist.

Cornetta (Flute in XVII - 13/5') - treble only, consisting of tapered flute pipes.

Voce Umana (principal-scaled, 8', treble only, tuned flat)

and finally the reeds:

Tromboncini      (trumpet-like regal at 8') bass and treble

Violoncelli (regal with wooden resonators - 8') bass and treble

Another "consort" stop, not present in the Feltre organ but rather common in Callido's instruments, is the Violetta, usually in the bass only, but also as a complete stop, especially in the later instruments. It is a 4' string stop of narrow cylindrical scale, tuned to the unison.

The Pedal division includes, in the Feltre organ, the following stops:

Contrabassi, Ottava di Contrabassi and Duodecima di Contrabassi.  These are three ranks of open wooden pipes at 16', 8' and 51/3' pitch respectively, which are activated simultaneously. In smaller organs only the first two (16' + 8') are present, or just the 16'. In the smaller instruments the 16' pipes are often found as stopped.

Tromboni ai Pedali (a trumpet-like reed, with 1/2 length resonators at 8' pitch)

Of particular interest are the reed stops, for their unusual shape and sound. The resonators of the Tromboncini are made of tin and consist of a lower four-sided portion and a "bell" on top. Their four-sided lead sockets are inserted into walnut boots. The tuning wires are made of brass, with cow horn sledges to facilitate the sliding over the tongues for tuning. The stop at low C (8' pitch) is of 1/8 length, the resonator approximately one foot long.

The Violoncello is even more unusual and complicated. Its resonators are made of cypress wood in the form of a stopped wooden pipe, the stoppers or caps being made of boxwood. The shallots are also made of hand carved boxwood, while the tuning wires, which go through the resonators and their caps on top, are equipped with cow-horn sledges. Unlike the sound of the Tromboncini, rather "biting" and penetrating, the harpsicord-like sound of the Violoncello is very sweet and gentle.

For many of his instruments Callido left a series of "operational instructions" for the organist, intended to give suggestions on how to best use the organ stops in combinations. Several of them, if strictly followed, show us how different the musical taste of the time was from the present. For example, under the title "Elevazione," or stops to be used during Consecration, for opus # 10 Callido specifies: Principale, Voce Umana, Contrabassi . . . and Tromboni! Not the type of pedal combination that we would consider appropriate for quiet meditation. And under the title "Corni da caccia," or sound to simulate the hunting horns, he suggests: Principale, Contrabassi, full ripieno (tiratutti), Tromboncini and . . . Voce Umana! An off-unison stop used along with the ripieno! (Opus # 5, 7, 9, 12, with the addition of the pedal Tromboni in opus # 10). Other combinations of stops are closer to what a contemporary organist would choose to do.

From the standpoint of construction, the instruments built by Callido are of unsurpassed quality. Each pipe is a true masterpiece, with thin, regular, absolutely perfect solder joints. The windchests and all other parts are manufactured with the highest attention for details. Callido was quite obviously trained in a very strict way and demanded the same perfection from his workers.

The contracts with his customers contain a very meticulous description of materials: pure tin for the façade pipes "without any alloy"11; "the rest of the internal pipes made of lead with a 20% alloy of tin."12 And he goes into detail to the point of stating that "the Contrabassi will be manufactured with spruce and painted inside and outside, and will be made of walnut at the mouth . . . " and also "the windchests will be made with walnut from Feltre13 . . . with metal parts made of brass."

It is certainly worth examining in closer detail some of the manufacturing characteristics of Callido's instruments. I will try to do so by describing the most significant components of the instrument in as much detail as it is possible within the reasonable length of a magazine article.

The keyboards

The most common compass of Callido's keyboards was C1-C5, for a total of 45 keys (with first "short" octave)14 or C1-D5, for a total of 47 keys. For the organs featuring the "counter" octave the compass consisted of four complete octaves, plus an extension at the bass consisting of a short octave, real from F1 as in the case of the Feltre Cathedral organ, whose Great manual has a total of 57 keys. When two keyboards were present, the Great Organ division keyboard was always placed on top and the coupling of manuals (Positiv to Great) was made possible by sliding the Great keyboard towards the back by a very short distance (drawer-type coupling, as it is often called in Italy).

The natural keys were normally covered with boxwood and the sharps were made of walnut painted black, capped with a strip of ebony, simple or with boxwood or bone inlays.

The "breaking point" between bass and treble was normally located between the notes C#3 and D3, except for the instruments featuring the "counter-octave," where it was placed between notes A2 and Bb2 .

The total width of a full octave was practically constant at 167 mm and the length of the keys was considerably smaller than in today's keyboards: 71 mm for the sharps and only 39 mm for the front portion of the naturals.

The pedalboard

It was always made with short, parallel and tilted pedals, common to the vast majority of historical pedalboards in Italy. It featured a first short octave and was always permanently connected to the corresponding keys of the manuals (of the Great, when two manuals were present). Its compass was of 17 notes, C1 to G#2, plus a pedal for the "Rollante," or drum, a device simultaneously activating a number of harmonically unrelated wooden pipes, thus reproducing the sound effect of the rolling of a drum. The compass of the pedal division in essence consisted of a full octave, since the notes of the second octave activated the corresponding pipes of the first.

The pipes

The façade pipes were made of pure or almost pure tin and all internal metal pipes were made of a tin/lead alloy with high lead content (about 80 to 85%). The metal was not poured on the table over cloth or marble, but over sand, and then planed by hand. Both the inside and the outside surfaces of the pipe resonators were made perfectly smooth. For the smaller internal pipes a laminating machine was used to roll cast metal into thinner sheets.

Since a few Callido organs, especially in the former territory of the Vatican State, have been found almost intact,15 it has been possible to identify not only the voicing parameters used by the builder but also, in some instances, the original tuning temperaments and wind pressures.

The flue metal stops were invariably voiced with some kind of wind control at the toe. Toe openings were generous, but the voicing could not be defined of the "open toe" type. Consequently, the flue was rather wide and this determined the need for nicking of the languids in order to avoid an excessive transient at the attack, which was obviously considered not desirable in 1700s Venice. Languids were nicked all the way to the smallest pipe in the ripieno ranks, but the nicks, although numerous, were very lightly marked and in some cases almost invisible. This created a precise, clean attack and still a clear and beautiful sound. This voicing practice has one exception: the languids of the Viola pipes were left totally unnicked. And no tonal bridges or beards, which were unknown to the Venetian tradition of the eighteenth and early nineteenth centuries, were used. Consequently, their sound features a very prominent transient at the start, intended to simulate the "noise" produced by the bow of the orchestral Viola when hitting the strings.

The low wind pressure was also a determining factor for obtaining a rich, unforced sound. It was usually set between 48 and 55 mm at the water column, with only a few verified examples of slightly higher pressure.16

Tuning was strictly done by cutting the pipes to length and adjusting with the cone, except for the façade pipes, which were cut close to length and subsequently fine tuned by further carving the back of the resonator at the top in a curved shape. These cuts are called "lunette", or moon-shaped cuts by Italian organbuilders.

Wooden pipes were always made of spruce, painted with a composition of light hot glue and red clay powder, with lower lip and upper lip made of walnut. The lower lip "cover" was fastened with hand-made iron screws. At 16' pitch these pipes could be stopped or open, depending on the size of the instrument. All open pipes were tuned with the cut-to-length method, with an occasional end correction made by applying small pieces of lead sheet or wood on top of the resonator to "shade" the note.

The windchests

The builder exclusively used the conventional slider chests, with table, top boards and sliders made of walnut. The sliders were all built parallel and of constant thickness.17 They always worked "wood-on-wood," without any form of leather seal or any other device intended to avoid the sticking of sliders. This of course required the use of high quality materials, but also a very clever choice of manufacturing techniques. It must be said, from this standpoint, that the "table" or the portion of the chest located under the sliders, which includes the note channels, was made of a solid board of walnut, 40 to 45 mm thick, on which the note channels were carved. This procedure is quite common in historical Italian slider chest construction, and differs substantially from techniques used at the time in northern Europe. Carving out channels from a single piece requires much more work than building a frame and creating the channels by means of inserting dividers, but this technique has a number of advantages. First, and most important, the whole unit is made from the same piece of wood, and this avoids warping and cracking due to contrasting tensions from different pieces of material. Also, the risk of air bleeding between note channels caused by an imperfect gluing of the different elements (table and dividers) is totally avoided, since gluing is not necessary, the elements being built from the same piece of wood. But since no tree would be wide enough to form a windchest table all in one piece, several portions were joined together for the purpose, with alternating direction of the grain in order to compensate for the tendency of warping all in one direction.18

The channels were always of generous size in order to provide adequate supply of air.19 Wooden dividers were placed inside the channels to avoid interference and wind supply instability between the larger pipes of the façade and the reed stops, which were invariably placed in front of the façade, exposed to facilitate tuning by the organist. The pallets were always made of light, straight-grain spruce from the Alps. Their seal consisted of a double layer of sheepskin leather, and the surface on which they rested was also covered by leather. This provided a very effective seal for the wind and apparently did not affect in any way the precision and sensitivity of the tracker action.

The Pedal division consists of only one windchest, located at the back of the organ case. The stop knobs for the Contrabassi pipes open or close a large valve located inside the windline, which controls the air flow to the chest. The reed, when present, is activated by a slider. In practical terms this means that the Tromboni cannot be played separately from the Contrabassi, because the Contrabassi stop knobs, and consequently the air valve, must be open to feed the whole windchest.

The mechanical action

Callido always used the suspended action, which is the simplest and most direct mechanical transmission mechanism. When a Positiv divison was present, always located at the left side of the keyboards, the corresponding keyboard worked in the same fashion, except that the keys is this case pushed down the trackers istead of pulling them.20

The rollerboards for the manual divisions, for the stop action and for the pedal, were made with forged iron rollers fastened to spruce boards by means of brass wire. The "swords" pulling the windchest sliders were also made of forged iron.

The winding system

The most common winding configuration in Callido organs includes two multiple-fold bellows (consisting of five folds) made entirely of spruce wood. They were normally placed one on top of the other and were activated by ropes through a system of pulleys. Their size was rather standardized: larger size bellows were used for the larger instruments, and smaller size for instruments requiring less wind.

Restorations are conducted in such a way that the original winding system is always preserved and carefully restored and, where not present, in many instances built new as a replica of the old.21 A modern blower is usually connected to the system, in such a way however as to keep the hand pumping system operational. This makes it possible to make a very interesting comparison between the original wind supply, slightly irregular due to the small but detectable differences in pressure caused by the manual pulling of the reservoirs, and the more stable supply furnished by the blower. "Flexible winding" as it is referred to today is a different matter: it has to do with the response of the wind and, in practical terms, the drop in wind pressure at the use of certain combinations of stops or notes. From this standpoint, although the phenomena of the so-called "flexible" wind is present in Callido organs, the design of the wind supply system, starting from the size of the bellows all the way to the generous dimensions of the windchest channels, indicates that Callido was trying to avoid instability in the wind supply.

The tuning system

As far as we know Callido never used equal temperament, already present in other parts of Europe at the time. Already well known for a few centuries, it was considered uninteresting and not desirable, especially due to the unpleasant "wide" tierce intervals which are present even in the most commonly used keys. An interesting statement on this subject is given by Giordano Riccati.22 In his book, "Le leggi del Contrappunto" written in 1754, he states: "Practically speaking, I have never been able to find an organ or an harpsichord tuned with the equal 12 semitones." In 1780 and 1790 he stated the same concepts again. But equal temperament continued to be rejected in Italy well into the 19th century. Giovan Battista de Lorenzi, a very ingenious builder from Vicenza, in 1870 created a "moderate temperament" which, although very close to equal, was intended to reduce the "out of tune" effect of the most used tierce intervals.

We know that Callido's master, Pietro Nacchini, for some of his works used a tuning method which consisted in tuning the 11 quint intervals from Eb to G# flat by 1/6 comma each, a method which was very close to the practice of Gottfried Silbermann.24 Callido may also have used this method, but he departed from it at some point and he adopted a variety of similar systems,25 among which the temperament invented by Francescantonio Vallotti, Music Director at the Basilica of St. Anthony in Padova, and Alessandro Barca in 1779, which avoided the wide G#-Eb interval, making it almost pure.26

A unique example of a non-codified temperament comes from the organ built by Callido's sons Antonio and Agostino in 1813 (the year of Gaetano's death at age 86) for the Parish Church of Tai di Cadore (Belluno). This instrument was restored by Fratelli Ruffatti in 1980-81. Prior to restoration, the pipes were found in almost perfect condition, due to the fact that the organ had been left untouched early in its history when the access stairway to the balcony was removed. After cleaning, the pipes were  almost in tune and it was relatively easy to identify and restore a type of unequal temperament which did not follow codified methods and which represented one of the many "variations" introduced by the tuners at the time for a "sensitive" tuning of the instruments.27

The tonal ideals and manufacturing techniques of the Callido factory were carried on, primarily in the Veneto and Marche regions, by a number of organbuilders: in Venice by Giacomo Bazzani, a former worker in his shop, and by his successors; in Padova and its province, among others, by Gregorio Malvestio, a priest (1760-1845), by his nephew Domenico, by Domenico's son Giuseppe and grandson Domenico. The closing down of this shop originated the beginning of the Ruffatti firm.28

In the Marche region Callido had a number of followers including Vincenzo Montecucchi from Ancona, Sebastiano Vici (Montecarotto, 1755-about 1830), Vincenzo Paci (Ascoli Piceno, 1811-1886) and others, who in some cases produced organs so close to Callido's techniques that sometimes their identification as non-Callido instruments requires an expert examination.29                   

Notes

                        1.                  His real name was Peter Nakic, born in Bulic, near Skradin, north of Sibenik, in present Croatia, a former territory of the Republic of Venice. As was customary during the time, his name was "Italianized" and became Pietro Nacchini.

                        2.                  The Republic of Venice during the eight-eenth century was a large State, including parts of Slovenja and Croatia and the present Italian regions of Veneto, Friuli Venezia Giulia and eastern portions of Lombardy.

                        4.                  Opus numbers 13, 185 and 393 were built for churches in Istambul and opus number 424 for Izmir, Turkey.

                        5.                  The original list or catalogue of organs built by Gaetano Callido survives. It consists of three panels made of canvas on which the opus number, year of construction and location of the instruments were marked in India ink by the builder. Although water damage washed away the names of 88 of his instruments, between the years 1789-91 and 1794-98, it still gives accurate information about 342 organs manufactured in his factory. The last opus number is 430, built in 1806, after which the list was discontinued. In recent years many of the "lost" instruments have been identified.

                        6.                  Only at the turn of the nineteenth century, when Callido's sons Antonio and Agostino were active in the factory, a limited number of "variations" were introduced, in the form of new reed stops (but still of the commonly used "regal" type) and flutes. Times were changing in Italy and a more "orchestral" style of sound, requiring highly characterized solo stops, was being introduced in churches, in the wave of the predominant influence of opera even in the music composed for organ.

                        7.                  This exceptional instrument, built in 1767 (opus numbers 37 and 38) and restored in 1979-80 by Fratelli Ruffatti of Padova, is practically equal in size to another organ, built for the Parish church of Candide (Belluno).

                        8.                  The Great keyboard of the Feltre organ is extended by one octave at the bass . This "counter-octave" as it is commonly called, consists of a short octave (C-D-E-F-G-A-Bb-B) of which only the notes from F up are real, the preceding ones activating the corresponding notes of the higher octave. In essence therefore the Principal starts in this case at 12'F, the Octave at 6', the Fifteenth at 3', etc.

                        9.                  This is the normal system used in Italy to designate not the pitch but the position on the keyboard. F3 for instance designates the note F of the third octave of the keyboard.

                        10.              Due to the absence of the "beards," which makes tuning adjustments possible when the caps are soldered, it is quite obvious that Callido must have had a very precise scale for cutting the resonators of these flutes to length before soldering the caps. Minimal tuning adjustments were however still possible through cone tuning of the chimneys.

                        11.              i.e.,  without the addition of lead, as reported in the specifications for the new organ to be built for the Madonna della Salute Church in Venice, dated September 19, 1776.

                        12.              Same, as above. In other contracts he chooses different alloy compositions for the internal pipes, as in the case of the contract with the Parish Church of Borgo Valsugana, November 8, 1780, where a 15% tin content is specified.

                        13.              The walnut from Feltre (Belluno) was traditionally of the highest quality, dense, dark and almost redish in colour.

                       14.              The short octave, or "broken" octave as it is often called in Italy, consists of 8 keys: C-D-E-F-G-A-Bb-B. The key arrangement is different from normal: basically, it looks like an octave starting from note E, where E plays C, F# plays D, G# plays E and all other notes are in the right place.

                        15.              This is the case of the organ in the convent Church of S. Anna in Corinaldo (Ancona), where Callido's daughter was a nun. The instrument, which is presently under restoration at the Fratelli Ruffatti shop, was found in remarkably good condition, still with the original hand-pumped bellows in good working condition. Since Callido was rightfully considered a master, his work was highly respected over the years by other organbuilders and for this reason the voicing of his instruments was often never altered in spite of the changes in musical taste.

                        16.              It is the case of the Callido organ at the Chiesa della Croce in Senigallia (Ancona), restored by Fratelli Ruffatti in 1993, where the original hinged bellows and their carved stone weights were found. Probably due to the unusually dry acoustics of the church, whose walls and ceiling are literally covered with elaborate wood ornaments and canvas paintings, the pressure was originally set at 60mm at the water column. Another example is the Callido opus 69, 1771 in the church of the Agostinian Fathers, Civitanova Marche. The instrument, restored in 1987 by Pier Paolo Donati, shows an original wind pressure of 64 mm (information courtesy of Dr. Massimo Nigi, honorary Inspector for the "Soprintendenza per i Beni Artistici e Storici" of Florence, a governmental agency in charge of supervising the preservation of Italian ancient works of art).

                        17.              This is not an obvious observation, since a great number of slider chests built in the 17th and 18th centuries in central and southern Italy were built with sliders non-parallel and of decreasing thickness. This feature was intended to avoid the sticking of the sliders. When in the "on" position, the sliders were pushed in and no space was left between the sliders and the other wooden surfaces; on the contrary, when pulled out (stop in the "off" position) the sliders, due to the decreasing thickness and width, could move freely.

                        18.              One might say that, during Callido's time, the problem of artificial heating of churches did not exist, thus making this procedure possible. It is to be noted on this subject that the very high number of strictly philological restorations on these organs by Fratelli Ruffatti and other restorers in Italy, performed without the introduction of any non-original elements for the sealing of the sliders, proves that the original system of windchest construction well withstands changes in heat and humidity level of the air.

                        19.              For a scale drawing of a Callido windchest see L'Organo Callido della Cattedrale di Feltre by Oscar Mischiati. Ed. Pàtron, Bologna, 1981.

                        20.              In this case the key pushes down a wooden tracker which in turn pushes down the rollerboard tracker placed under the keyboard. At the opposite end of the roller the pallet is pulled open by means of a brass wire.

                        21.              In some cases, where the original bellows were replaced in the nineteenth century by the more "modern" multi-fold parallel bellow with pumps, activated by means of a wooden lever or a wheel, the local governmental authorities designated to supervise the preservation of ancient instruments may choose not to have the system rebuilt as a replica of the original but to keep the already "historical" substitute.

                        22.              Born in Castelfranco Veneto (Padova) in 1709, he studied at the University of Padova and became a famous mathematician, architect, expert in hydraulics and music. He was the author of an interesting temperament, which became famous at the time, used by many organbuilders especially in the Venetian area. It was surely used in his later works by Nacchini and possibly by Callido as well.

                        23.              See Patrizio Barbieri, Acustica Accordatura e Temperamento nell'Illuminismo Veneto, Ed Torre d'Orfeo, Roma 1987.

                        24.              See Patrizio Barbieri, Acustica Accordatura e Temperamento nell'Illuminismo Veneto, Ed Torre d'Orfeo, Roma 1987.

                        25.              The result of studies conducted during restorations show that a variety of similar temperaments, which can be defined as variations of the above Riccati and Vallotti temperaments, were used in normal practice.

                        26. The Vallotti temperament in the slightly corrected version by the contribution of Barca, was intended to simplify the Riccati, and consists of a series of six consecutive quint intervals, from F-C to E-B tuned flat by 1/6 comma, and the six remaining quint intervals practically pure (flat by an imperceptible 1/66 comma). The value in cents of semitones of its quint and tierce intervals follow:

Quint intervals cents

F - C        698.4                              C - G      698.4      G - D      698.1                              D - A      698.6                              A - E       698.4                              E - B       698.4                              B - F#    701.7                              F# - C#                        701.5                              C# - G#                      701.6                              Ab - Eb                       701.7                              Eb - Bb                       701.6                              Bb - F    701.6                                                     

Tierce intervals                      cents      

C - E       393.5

F - A       393.5

G - B      393.5

Bb - D  396.5

D - F#   397.1

A - C#  400

Eb - G   400

E - G#   403.2

Ab - C  403.3

F# - A#                       406.4

Db - F   406.5

B - D#  406.5

                       

Keeping in mind that the value of the pure quint is 702 cts and the value of the quint in the equal temperament is 700 (narrow by 2 cts), by analysing the quint intervals of this temperament it is easy to see that they are basically divided in two categories, narrow (but more moderate than, for example, in the 1/4 comma mean tone, which shows a value of 696.5 cts.) and almost pure. As to the tierce intervals (pure tierce = 386 cts, tierce in equal temperament = 400 cts) although no pure intervals are present, five of them are "better" or more in tune than the corresponding ones in the equal temperament, and two more show the same value of 400 cts. It is also to be considered that no tierce reaches extreme values. The absence of really unusable keys and the relatively easy application in practical terms by the tuner have determined the success of this temperament during its time.

                        27.              The Tai temperament includes two "wolf" quint intervals, at the opposite ends of the "circle of quints," one wide (G#-Eb) and one narrow (A-E) and six very good tierce intervals. This system is of particular significance primarily because it shows how far from equal temperament this organ was tuned so late in Callido's history.

The sound

Designing an organ presents many challenges, many of which are related to making the instrument fit tonally and visually into the building which will be its home. The challenges connected with our recent installation at Buckfast Abbey, Devon, England, were, in many ways, out of the ordinary. We were asked to design two instruments of considerable size, tonally interconnected, for a building of moderate size and very kind acoustics that amplify sound in a dreamlike fashion. While it was not difficult to design an instrument to play a variety of literature, much attention was required to scaling the sound to the building without sacrificing the proper characterization of the many different stops.

The tonal palette was based on an initial draft by Matthew Martin, international recitalist, former organist at the London Oratory and now Fellow and Director of Music and College Lecturer at Keble College, Oxford. Further adjustments were coordinated between Philip Arkwright, Organist and Master of the Music at Buckfast Abbey, and Fratelli Ruffatti.

The main instrument, of four manuals and pedal, is located on two sides behind the choir stalls and partially on the triforium level (the upper arcaded gallery) above. Specifically, Great, Positivo (in the Italian style, hence the name), Swell, and Pedal are housed inside solid oak cases at nave level, while the Solo division is placed at triforium level, along with a whole series of “special effects” playable from the Positivo, some of which belong to the early Italian tradition.

The second instrument, comprising two manual divisions with full pedal, is located in the west gallery and partially in the triforium level areas that are closest to the west gallery. Two nearly identical four-manual consoles have been provided, one in each location. The difference between the two is that the Quire console is equipped with an electric lift that adjusts the height of the keydesk and stop jambs by more than four inches (10 centimeters). This feature, along with the two height-adjustable benches (one for concert use, and one for teaching purposes), makes it very easy for any organist to find comfortable playing space. 

As G. Donald Harrison, the Englishman who became tonal director of Aeolian Skinner, once stated, “To me, all art is international; one can draw from the best of all countries. I have used the technique at my disposal to produce instruments which I consider suitable for expressing the best in organ literature.” This instrument indeed embraces this philosophy. The requirements for the seven initial worldwide organbuilders that were asked to submit specifications included the need for the instrument to support a wide repertoire of accompanied music, as well as to successfully perform a wide range of organ literature. Such requirements were not taken lightly and, drawing from decades of experience and from different traditions, as Harrison advocated, Ruffatti introduced several tonal features that are new or rare to find in England, with the aim of sparking interest for improvisation and creative registration for the international repertoire. 

It is along these lines that the Gallery Organ was designed. It draws from the French Romantic tradition of Cavaillé-Coll. Dedicated studies were conducted on several organs in Paris and other locations in order to ensure as close a proximity as possible to the Cavaillé-Coll style, by carefully copying pipe measurements and voicing methods, without pretentious claims of authenticity. The instrument is designed as a two-manual, but it can also be used as a large cohesive division, part of which is under expression, that can be played against, or in tandem with, the main Quire Organ. 

Along the same line of thought, the Italian Positivo was introduced in the Quire. With the tonal consistency of an early Italian instrument and the trademark low-pressure voicing, it provides all tonal resources needed to faithfully perform classical Italian literature from the Renaissance up to the early Romantic period, an ingredient that is indeed rare to find in an instrument in England. It is also ideal for playing in alternatim with the monastic choir. This is not just a nice “toy” to have, but serves convincingly as a Positiv division, in dialogue with the Great for access to a broader classical repertoire.

Another note of interest concerns the Solo division, which includes stops that have been drawn from the Skinner tradition, as well as other orchestral stops of Ruffatti design.

One of the aspects characteristic of Fratelli Ruffatti is that we manufacture almost everything in house, including flue and reed pipes. This is the best guarantee for quality control. At the same time, it provides the opportunity to carefully select all the ingredients that are necessary in the mind of the tonal designer. The difference is in the details. Being able to pass any requirements that experience dictates on to the pipe shop enables the voicers to exactly tailor the sound to the room, resulting in that perfect blend for which Ruffatti is famous.  

Versatility is only partially the product of having a variety of stops on hand; what really makes the difference is the ability of each stop to combine successfully with all others to produce countless tonal combinations. Open-toe voicing for principals and flutes is the key, as it favors blending of sounds, as well as promptness and precision of speech, an aspect that is of paramount importance, especially when there is no close proximity of the player to the pipes (as there would be with a mechanical action instrument). An old misconception still flies around, deriving from the early neo-Baroque times of the Orgelbewegung, or Organ Reform Movement of the mid-twentieth century, where the open-toe voicing technique was sometimes used to produce excessively harsh sounds. Open-toe voicing is instead quite versatile, ideal for the effective voicing of a rank of pipes in a variety of styles, regardless of the chosen wind pressures. 

Materials for the construction of pipes include the ultra-shiny alloy of ninety-five percent tin, used for the pipes in the façade as well as for a high number of larger internal pipes. Its structural strength and incredible resonance properties make it ideal for pipes of larger size. Other internal pipes are made with a tin percentage ranging from 75 to 30 percent.

Many pipes are made of wood, including the resonators of the two majestic 32′ reeds, the Bombarde, and the Fagott. Only the finest African Sipo mahogany has been used, varnished inside and out to enhance resonance. The Pontifical Trumpet, which projects horizontally from the front of the Gallery Organ, has highly polished solid brass resonators.

This organ was featured in the press for the first time in the March 2018 issue of the British magazine Organists’ Review with an article by Philip Arkwright, Organist and Master of the Music at Buckfast Abbey. It was inaugurated on April 20, 2018, with a splendid concert performed by Martin Baker, Organist and Master of Music at Westminster Cathedral, which I had the good fortune to witness. The improvisation that closed the performance was stunning: a perfect demonstration of creativity and a kaleidoscopic use of musical color.

The opening organ series also includes concerts by Vincent Dubois, titular organist of Notre Dame Cathedral, Paris; David Briggs, Artist-in-Residence at St. John the Divine, New York City; Matthew Martin, Director of Music at Keble College, Oxford; Richard Lester, international recitalist; and in-house organists Richard Lea and Matthew Searles.

Architecture and technical features

The east and west organs at Buckfast Abbey are aesthetically quite different. The east organ (Quire) is intended to be discreet, as the client’s desire was that the front of the building should not have the imposing presence of an intricate organ design. For this reason we chose a very simple layout for the façade, with pipes recessed into three arches that crown the stalls on both sides of the Quire. The pipes are hardly visible from the center of the building, but clearly show the brightness of the tin they are built from when they are seen from the side.

The central pipe of each bay, with its diamond-shaped embossing, reflects the light in all directions, providing a touch of richness within the simplicity of the design scheme.

The west organ (Gallery) gave us the opportunity to offer a more sophisticated architectural solution. The full visibility of the splendid stained glass windows being paramount, we built two symmetrical oak organ cases against the side walls of the gallery, with tunnels to grant access to the balcony from the doors in the back corners. The aim was for a design of lightness and richness at the same time—not an easy task, as the two qualities are normally in conflict.

To achieve this goal, we chose a case design where the façade pipes are not topped by a ceiling. Instead, there is an alternation between bays having pipes with unobstructed tops and pipes with carved elements defining the top line. The richness is provided by the carving, which is also used to separate façade pipes within the same bay. In the general scheme, it gives visual continuity to the various bays. These elements have been hand-carved from European oak by a gifted artist, from a Ruffatti design inspired by the intricate and elaborate carved wood of the Abbey’s choir stalls. Even the panels of the lower part of the case are enriched by carvings in the Gothic style. 

The sunlight coming through the stained glass windows is reflected by the shiny surface of the tin pipes, adding a touch of color to the façade, an effect that is remarkably spectacular.

The signature Ruffatti horizontal trumpets, with their flared brass bells, extend from the lower part of the cases, projecting their shining beauty into the Abbey’s central bay.

The most frequent comment we have received on the design is that the organ looks like it has always been there. I believe that this is the biggest compliment that can be paid to the designer, because it proves that the organ belongs to the building, without imposing its presence. The initial aim has been reached: a light yet elegant result.

On the strictly technical side, African Sipo mahogany is widely used for functional parts, such as all of the windchests. The main units are of the slider type, which are controlled by solenoids of the latest generation, featuring self-adjusting power for the initial stiffness of the slider movement and reduced power at the end of the travel, for maximum silence.

The twin consoles feature identical controls and can be played simultaneously, as they often are. The control system is operated by the organist from a touch-screen panel, and it offers a large number of functions. The huge memory provides separate password-protected storage folders for many organists, where stop combinations, personal crescendo, and tutti settings can be stored. The system also features, among many other useful tools, a transposer, a record/playback function, and on-board diagnostics, a useful tool for maintenance.

The height adjustment of the keydesk of the Quire console is controlled by a push button, operating a heavy-duty electric motor. Adjusting the level of the keydesk allows maximum comfort for the player, regardless of that person’s physical height and build.

The organ is distributed over several locations and, true to Ruffatti philosophy, uses several different wind pressures to optimize the tonal result of the various stops. As a result, nine separate blowers, twenty traditional reservoirs, and nine schwimmers have been used to provide adequate and stable wind at the many different pressures, ranging from 40 to 185 mm.

She is an active composer and has performed recitals in the U.S.A., Scotland, and Italy. She is a frequent contributor of reviews and articles to The Diapason. Dr. Kraaz spent several weeks this spring researching and playing historic organs in Italy and Spain during a sabbatical leave.

  In a perfect world, we organists would always be able to play music on the instruments for which it was written. Putting music and organs from the same time and place together produces a beautiful synchronicity, the closest thing to time travel we can experience. Happily, this was recently my fate. What follows is a description of some music and instruments that have expanded my understanding of a particular musical tradition. They will continue to inform my performances.

On March 6, I played a recital of Italian music on the Vespers Series of the Giuseppe Gherardeschi Organ Academy in Pistoia (www.accademiagherardeschi.info). Pistoia is a small city in Tuscany approximately 30 miles northwest of Florence. The remains of a medieval wall circumscribe the old town whose Cathedral of San Zeno houses a silver altar dedicated to San Jacopo, thereby putting it on the pilgrimage route to Santiago de Compostela in Spain. The cathedral, the former Bishop’s Palace, the Baptistry, and the Town Hall, all dating from the 13th–15th centuries, surround a central piazza that even today dominates the center of Pistoia. An open-air fruit and vegetable market, shops, restaurants, and cafes spread out from there in a web of narrow cobblestone streets. Wednesday and Saturday mornings are market days, when stalls appear in the centro selling everything from clothing to kitchenware. Bells from the many churches in the city mark the passage of time. Pistoia is off the beaten track for tourists. It’s a great place to visit if you want to mingle with Italians who live comfortably in the present while surrounded by the past. The city and neighboring towns are also home to a number of historic organs, most of them from the 18th and early 19th centuries.¹

 

Giuseppe Gherardeschi

A brief biography in the New Grove Dictionary of Music and Musicians² states that Gherardeschi was an organist, composer, and eventually maestro di cappella at the cathedral; except for a brief period of study in Naples, he spent his entire life in Pistoia. He began his musical studies with his father, Domenico (1733–1800), who was maestro di cappella at the cathedral, and continued with his uncle, Filippo Maria (1738–1808). The latter, also a Pistoia native, had been a pupil of Giovanni Battista (a.k.a. ‘Padre’) Martini³ in Bologna from 1756 to about 1761, when Filippo was admitted to the elite Accademia Filarmonica. Giuseppe completed his formal studies with Nicola Sala at the Conservatorio di Santa Maria della Pietà dei Turchini, one of three music conservatories in Naples. Upon returning to Pistoia, he married, fathered seven children, and became organist at the church of Santa Maria dell’Umiltà. When Domenico Gherardeschi died in 1800, Giuseppe inherited his position as maestro di cappella at the cathedral, a post he held until his death. In the tradition of the Bachs and Couperins and other families of musicians at the time, Giuseppe’s son, Luigi (1791–1871), and grandson, Gherardo (1835–1905), succeeded him. The Gherardeschi men all composed sacred vocal and instrumental music, much of which survives in the cathedral archives. Giuseppe did not confine himself to music for the church, however; five symphonies, all in the three-movement fast-slow-fast pattern favored by Giovanni Battista Sammartini and other 18th-century Italian composers, survive, as do numerous arias, chamber music, and oratorios.⁴

Umberto Pineschi’s edition of 

Gherardeschi’s organ works

That we know anything at all about the life and music of Giuseppe
Gherardeschi—and consequently, about the contemporary Tuscan organ—is due to the almost single-handed efforts of Umberto Pineschi. Organist, teacher, scholar, founder of the Gherardeschi Organ Academy, and now in “retirement” Director of the Scuola Comunale di Musica e Danza “Teodulo Mabellini” in Pistoia, Pineschi has worked tirelessly to locate, preserve, and restore organs in and around Pistoia. He edited the organ works of Gherardeschi for publication beginning in 1978. The first collection was followed by a second, third, and fourth, but as he confesses in the foreword to the newest edition (in Musiche Pistoiesi per Organo, published by the Fondazione Accademia di Musica Italiana per Organo in 2009), there was “no organized plan, since every time only the pieces considered interesting at the moment were selected.” Further, he adds, “Their context, often crucial for their understanding, was not taken in[to] account. Such a fragmented presentation of the Gherardeschi organ works did not allow one to fully appreciate both their lesson on the Pistoiese organ and the artistic relevance of the composer.”⁵ Pineschi here refers to the symbiotic relationship between organ music and the instruments for which it was written, in this case Pistoiese organs of the 18th and early 19th centuries. These deficiencies are addressed in the new edition, which is the basis for the discussion that follows.  

The present volume brings together all of Gherardeschi’s known compositions for organ, including some that have never been published. The pieces appear in the same order as in the manuscripts. Pineschi identifies several groupings by genre: 1. Sonatas; 2. Masses in C and D (Offertorio, Elevazione, and Postcommunio) and a Mass in E-flat that has versets for alternatim performance with the Ordinary; 3. Collections of versets; 4. Miscellaneous short pieces, including a colorful Sonata per organo a guisa di banda militare che suona una Marcia, two pastorales, and a fugue in G minor. Each piece has been assigned an opus number (a P followed by a number). Strict classification according to this scheme is impossible, however, since two of the sonatas (P.IV [1787]) are rondos and a number of the Mass movements (the Elevazione in D, P.I,5; the Offertorio in C, P.I,7) are sonatas. Elements of secular genres, including the concerto, aria, and symphony, also define and shape these pieces in a manner surely intended to entertain as well as sanctify the listeners.

Since the purpose of this article is to present an overview, rather than a comprehensive discussion, of Gherardeschi’s works, representative examples from each of the categories above will highlight important stylistic features of the music and the organs for which they were written, beginning with the sonatas. These all conform to the binary form and tonal design of the 18th-century keyboard sonatas of Domenico Scarlatti and others.

 

Offertorio, Mass in C: 

a representative work

The Offertory in an organ Mass is generally longer and more elaborate than other movements because it provides music during the preparation of the Eucharist. Gherardeschi takes advantage of these large dimensions by writing the Offertorio from the Mass in C as a sonata. The movement begins assertively with strong tonic chords in the left hand against clearly articulated right-hand rhythms in a 4-bar phrase. This antecedent phrase is answered by a consequent phrase in a reduced texture and registration, much like a dialogue between the tutti and solo parts of a concerto (Example 1). Indeed, Gherardeschi’s registration directions support this impression: initially, he calls for ‘[ri-]pieno con Trombe (trumpet)’ and ‘Timp[ano]’ in the pedal, which would be the equivalent of a full orchestra. The second phrase is labeled ‘p[ieno] senza ripieno [i.e., without the Trombe] e senza ped[ale]’. Without the trumpet (soloist) and pedal + timpani, the effect is of an echo. This alternation continues throughout both sections of the Offertorio. The texture is open, treble-dominated, and non-contrapuntal; occasional octaves in the manuals add a bit of dramatic emphasis at times. Harmonically, the music is predictable, with the first (A) section ending in the dominant key of G major. The B section opens in G minor, however, and moves to d, a, and F before returning via the dominant G to C.  

The energy, rhythmic drive, clear tonal design, and concerted style of the Offertorio reveal how steeped
Gherardeschi was in the music of Corelli, Vivaldi, and Sammartini. Written at the end of the 18th century, as Vienna and Paris were eclipsing Italy in the development of instrumental music, these pieces remind the listener of the connections among the various schools.

The concerto and symphony are not the only models for this music, however. Pineschi observes that the influence of opera and the theatre is clear in the Masses: “Indeed, the Offertori show the influence of the overture, the Elevazioni and the Benedizioni that of the romanza, while the Postcommunio echoes the always attractive spirit of the cabaletta; all, however, display whimsy, balanced proportions, and, above all, good taste.”⁶  

In fact, two of the three Masses in the collection, those in D and C, consist of exactly these movements, that is, Offertorio-Elevazione-Postcomunio. In modern usage, these may stand alone or be played in concert as a group of fast-slow-fast movements. The remaining Mass, in E-flat, is more complex because of versetti that alternate with chant. The Table of Mass movements summarizes the shape and content of the Messa in Elafá. One observes immediately the variety of tempos, meters, and registrations Gherardeschi uses in the versetti. The last aspect is the most important, for it tells us a great deal about the late 18th-century and early 19th-century Tuscan organ in general and the Pistoiese organ in particular. In this regard, the Mass resembles the other sets of versetti in the collection, all of which specify different stops as solos or in combinations.  

 

Registration

Gherardeschi frequently calls for “organo aperto” in his music. This means the complete Ripieno (Principale 8′, Ottava 4′, Decimaquinta 2′, Decimanona 11⁄3′, and two or three high-pitched ranks combined, the Vigesima seconda e sesta [1′, 2⁄3′] or seconda, sesta e nona [1′, 2⁄3′, ½′]), plus the Trombe (trumpet) 8′ and Cornetto.⁷ This combination, the equivalent of a full organ without flute stops, produces a clear and brilliant but not overpoweringly loud sound. “Pieno” refers to the complete or partial (i.e., 8′, 4′, 2′) Ripieno (Gherardeschi does not specify which). All the other combinations in the Messa call for specific principal and ‘da concerto’, i.e., solo, stops, including some divided stops (Musetto treble 8′; Clarone bass 4′; Trombe bass 8′). Stops divided between bass and treble registers have been a feature of Italian organs since at least 1664, when the Flemish Jesuit, Willem Hermans, built an organ for the church of Sant’Ignazio di Loyola (known in later times as “Spirito Santo” and since 1 February 2011, again as Sant’Ignazio) in Pistoia.⁸ They are advantageous on a small organ. In Pineschi’s words, “Gherardeschi’s clever use of the divided stops allows one to casually move from the bass section of the keyboard to the treble section and the other way round in such a way that the listener has no time to realize that.”⁹ He might have added that Gherardeschi must have possessed uncommon dexterity, given the lack of mechanical aids for registration changes and the fact that many of these occur in the middle of a piece. Perhaps he employed an assistant, maybe his son Luigi as organist-in-training. Pineschi suggests that these directions to change or add divided stops (which always occur at cadence points) reflect spontaneous changes made by Gherardeschi when he was improvising, as experienced organists did; the written version is for organists who were not as skilled or experienced in the art of improvisation.¹⁰

Of course, Gherardeschi’s registrations reflect and reinforce the character of individual versetti in the Messa; rhythms, tempos, and styles complete the picture. The first and last Gloria verses are of particular interest because they are cast as marches in duple meter with an abundance of dotted rhythms, repeated chords, triadic openings, trumpet-like solo lines, and liberal use of a “special effect” Timpano stop (from two to six wooden pipes, out of tune in such a way as to give a kettle-drum effect, operated by a pedal played by the right foot). The first Gloria verse begins with a fanfare in the manual accompanied by pedal and Timpano. In measure 5, another special effect (also played with the right foot), the Usignoli (Nightingale) stop, appears alternately with the timpani to simulate the trills of a clarinet¹¹ (Example 2a). Marches, whether for military bands or in concert music, were a common and popular musical genre in the 18th century.¹² As such, they connoted heroism, vigor, cheerfulness, and manliness.¹³ Gherardeschi was not the first composer to set the “Et in terra pax” couplet to a march; François Couperin had done that 100 years earlier in his Messe pour les couvents.¹⁴ Undoubtedly, the triumphal, affirmative nature of the text is a determining factor in the choice of musical style, but in the Messa there is more to the matter. Napoleon invaded Italy in 1790, defeating the Austrian army. The next 15 years were tumultuous ones in all the regions of the Italian peninsula, when French-initiated political and social reforms met with strenuous opposition from many Italians and the Church. The return of Austrian rule in 1815 after the Congress of Vienna, repressive as it was, was hailed as a return to order and normality.¹⁵ Gherardeschi composed his music against this backdrop of political turbulence amid constant reminders of a military presence. The Sonata . . . a guisa di banda militare even includes the “Janissary style” derived from Turkish military bands, a type of march in which cymbals, bass drum, and triangle are implied in the instrumentation (Example 2b, see page 28). Marches figured prominently in operas, symphonies,¹⁶ and secular keyboard music in the late 18th century, so it is not surprising to find them in organ music as well.

 

Versetti

In the preface of this volume, Pineschi lists the versetti as a third group after the sonatas and Masses. These works, though individually brief, are the most numerous and perhaps the most important for what they tell us about the Pistoiese organ of the time. There are two types of versetti, distinguished by their registrations. Versetti a pieno require the
[ri-]pieno, or full, sound, with only a tempo indicated at the beginning (the registration is implied) (Example 3a); versetti concertati require use of the ‘da concerto’ stops and have specific registrations provided at the beginning of each piece (Example 3b). From these, we learn the tonal design of the organs for which
Gherardeschi wrote his music.¹⁷ The ‘da concerto’ versetti are also labeled ‘solenni’, referring to their intended liturgical use in the Mass or other services, especially the Office of Vespers (e.g., the Magnificat). Versetti are written in all eight psalm tones, as one would expect. Interestingly, the versetti a pieno, P.II, are only figured basses; the organist must realize them in performance. Obviously this Baroque musical shorthand was still proving useful at the beginning of the 19th century.

 

Organs

Specifications for four organs that
Gherardeschi would have known appear in the preface to the Opere per organo. The first, by Hermans, was the prototype for the rest, which were built in the 1780s and ’90s by Antonio and Filippo Tronci and Pietro Agati. These instruments have been preserved and restored in Pistoia and Lucca. A similar organ built by Luigi and Benedetto Tronci in 1793 has been in the Cathedral in Pistoia since Pineschi rescued it from the chapel of the Rucellai villa, Campi Bisenzio (a small town between Prato and Florence), in 1998.  This is the instrument I played every day for five days in preparation for the Vespers performance. It is, amazingly, in its original condition. The specifications are as follows (For photos and audio clips of the Hermans and Tronci organs, visit The Diapason website,

Ripieno stops

Principale 8′ (first eight pipes are wood and play without drawing a stop because they are placed on a separate chest; the remaining pipes are tin, with C2 the major pipe of the façade)¹⁸

Ottava 4′

Decimaquinta 2′

Decimanona 11⁄3′

Vigesima seconda e sesta (1′, 2⁄3′)

 

‘Da concerto’ stops

Flauto 4′ (from C2)

Cornetto I (soprano 4′, 13⁄5′)

Cornetto II (soprano 22⁄3′)

Voce languente (the same as the Voce umana, soprano 8′)

 

Special effects: Timpano, Usignoli

Manual compass: 47 notes, C1–D5 with short octave at the bottom)

Pedals: eight notes (C–G), short octave, always coupled to manual

Divided registers between E3 and F3

 

As other writers have observed, having the ranks of the ripieno available as single stops (rather than as a multi-rank mixture stop) presents a multitude of registrational choices, many of which are subtly different. I enjoyed getting to know the sounds of all the stops individually and in various combinations. The Tronci keyboard has a uniform and light touch perfectly suited to the lively, graceful lines of 18th-century music. Using the short octave on both manual and pedal requires re-patterning of both cognitive and muscle memory. (What usually feels like a fifth is now a second, for example.) The short pedals are also quite different; one hardly needs organ shoes to play them, since only toes are used—heels remain on the floor. To sum up, playing an instrument like this, so different from a modern organ, requires total concentration, since all the senses—visual, auditory, kinesthetic—are involved in sometimes unfamiliar ways.

I hope this brief introduction—to the music of a composer who, in his own lifetime, was well known and highly respected in Tuscany, and to one of the organs he could have known—will encourage interest in both topics. This delightful, lively, and lovely music deserves to be better known on this side of the Atlantic. At present, the Opere per organo is only available from the editor, Umberto Pineschi, at . It is well worth the effort to obtain the book.
