Modeling Tournemire: Preludes

SeniorRecitalCoverI planned my senior recital at Westminster Choir College for Sunday evening, October 31, so I decided to include some selections appropriate for the day. I opened with the Bach Toccata and Fugue in D minor, concluded with the Toccata from Louis Vierne’s Pièces de Fantasie. In the middle of the program, I played the complete L’Orgue mystique, no. 48 for All Saint’s (November 1). this was the second suite from L’Orgue mystique that I learned. The first was no. 17 for Easter which I had learned and played for a chapel service earlier in the spring at the request of my chant teacher, Fr. Gerard Farrell. Fr. Farrell was not only a chant scholar, he was an organist and had studied with Flor Peeters. Fr. Farrell’s love of chant the organ music based on it definitely led to my interest in the music of Tournemire and improvisation.

The Prélude

The first movement of the suite for All Saints is a simple one page prelude. It alternates a brief harmonic progression with accompanied presentation of portions of the introit chant Gaudeamus omnes in Domino. I have marked up a copy of the score here showing the alternating sections. In it’s simplest description, the piece is a seven part rondo: ABABABA with A being simple harmonic fill and B containing the theme. This plan of alternating sections will be our model for the form. The tonal language of the accompaniment is simple, staying virtually all the time in the mode of the chant providing atmosphere more than following traditional harmonic progressions.

Advent

In Tournemire’s day, the organ was not used during the season of Advent except on the third Sunday, referred to as Gaudete Sunday and the Feast of the Immaculate Conception. As most organists continue to play during the Advent season now, I thought it would be a good idea to take themes from Advent and apply Tournemire’s forms and ideas to them in order to fill in the gap in today’s repertoire not covered by L’Orgue mystique. Perhaps the best know Advent theme today is Veni Emmanuel, a modal chant tune that I’m sure Tournemire would have used if he had needed to write more organ music for the season.

One of the tasks that I’ve suggested from time to time that will help us become better improvisations is to actually take pencil and paper and write out our ideas. I took the time to craft a Prélude à l’Introït on Veni Emmanuel following rather closely Tournemire’s prelude for All Saints. (Donwload the score here.) While I can claim it as a composition, it really is simply an example of how we can take the form and ideas from Charles Tournemire and apply them to themes that we know and use in our liturgies today. I encourage you to play through both the scores and to try your hand at improvising your own prelude following this model on a theme of your choice.

Videos

While I haven’t managed to make a video lesson of this yet, I was able to record performances of both the All Saints Introit and my Advent version. I also recorded an improvisation on Adoro Te Devote following the same idea (and registration). None of these is terribly long, but they can be fabulous ways to fill a couple of minutes, introduce a new tune to the congregation, or even provide an introduction to singing a hymn. I hope these lessons and examples will lead you to enjoy and discover the music of Charles Tournemire as I was led to it by Fr. Farrell.

May your improvisations be inspired,

Glenn

The Liturgical Suite 200 Years Later

While the 200 years between François Couperin and Charles Tournemire offered a substantial contribution to organ repertoire (with pieces of both great and dubious quality), after the French Classical suite, the next substantial collection of liturgical suites for organ is L’Orgue mystique of Charles Tournemire.

Charles Tournemire

Tournemire2Charles Tournemire served as the organiste titulaire at the Basilique Ste-Clotilde in Paris and taught Chamber Music at the Paris Conservatoire. He has been described as a mystic with a deep faith in the Catholic Church. L’Orgue mystique is a series of 51 suites covering all the Sundays and major Feasts when it was permissible to use the organ. Most suites contain five movements as follows:

  1. Prélude à l’Introït
  2. Offertoire
  3. Élévation
  4. Communion
  5. Pièce terminale

While the French Classical movements were named by their registration, Tournemire identifies each movement only with its location in the liturgy. Virtually every movement references at least one Gregorian chant that was sung if not immediately before or after the organ piece at some other point during the celebration of the day. These chants were probably known by many organists of Tournemire’s time, but as he does not identify the chants in the composition, we are dependent upon researchers like Robert Sutherland Lord who have spent time identifying the chants included in each movement. Many can be found easily, but changes in liturgical books over the years have made some harder to identify than others.

Teaching Models

Just as the Orgelbüchlein and some other collections of J.S. Bach were written for teaching purposes, I believe Tournemire’s L’orgue mystique also had a teaching application. This collection is a catalog of compositional ideas and demonstration manual for improvisation in the Mass. Though still under copyright in the US, the collection is in the public domain in Canada, the EU, and in those countries where the copyright term is life+70 years or less, and thus may be found on IMSLP. Because I had an employee discount while working at a music store when I was a student and had plenty of cash to build my music library (and well before a resource like IMSLP had even been dreamed of), I actually purchased hard copies of almost every volume of the series. (I have two copies of one volume and am missing another because I tried to order the one I was missing but mistakenly ordered the wrong one.) I encourage you to purchase (or download where legal) several of the volumes so that you may study the way Tournemire treats chant. Over the next few weeks, I plan to take different movements from the suites as models for improvisations and suggest ways that we can build new pieces following what Tournemire has shown us.

For a head start on Tournemire’s style, beyond actually studying the scores, I will point you to a handout that David McCarthy prepared on the Five Improvisations of Tournemire available at http://davidmccarthymusic.com/technique.htm. David identifies lots of keyboard figuration which will be helpful to know as we seek to model Tournemire’s style.

Thank you

This newsletter marks number 50 that I have written, so I want to thank all of you who have subscribed, continue to read and share your feedback with me. I started this website and newsletter to try and accumulate the seemingly few resources on improvisation into one location. Thanks to help from readers like David, my own knowledge continues to grow, and I have located many other resources to share with you. I look forward to finding, creating, and sharing more resources with you in the future so that you too may continue to become better improvisers.

Hoping your improvisation skills are improving,

Glenn

The Final Grand Jeu

In concluding this series on the French Classical Suite, we come to one of the most impressive sounds of the French Classical organ, the ensemble of reeds. Virtually every time I sit down at a historic instrument and pull out the small number of stops required for the Grand Jeu, I am impressed by the volume of sound. Listen to Jean-Baptiste Robin play Louis Marchand’s Grand Dialogue at Poitiers to hear what 6-7 stops can produce!

Registration

The Pre-classical Grand Jeu registration consisted of:

  • G.O.: Trompette, Clairon, Cromorne, Cornet, Tierce, Bourdon 8, Nazard, Quarte de Nazard

A distinction emerged in the Classical period between the Grand Jeu using the registration above and the Grand Dialogue which omitted the Jeu de Tierce:

  • Pos: Montre 8′ or Prestant 4′, Bourdon 8′, Cromorne
  • G.O.: Bourdon 8′, Prestant 4′, Trompette 8′, Clairon 4′, Cornet

As the organs grew larger and the Dialogue advanced, the registration expanded to:

  • Pos: as above
  • G.O.: as above
  • Récit: Cornet
  • Écho: Bourdon, Prestant, Doublette, Nazard, Tierce

Use of the pedal depended upon the organ, but was based on the Trompette, adding the Clairon and then Bombarde stops if available. Couperin and Boyvin specify the flute stop on the pedal when they include trio passages in their dialogues.

Forms

Multiple forms are used with this registration including Pedal points, Fugues, Dialogues, and Overtures. In an early suite, the Grand Jeu may only be 10-12 measures long and played entirely on one keyboard. Later composers created 10-12 minute Dialogues exploiting the varied palette of colors and demonstrating a variety of writing styles. For a short movement with a little variety, the overture provides an easy example for us to follow.

Start on the Grand Orgue in a slow tempo. Use dotted rhythms. Scales by either the right or left hand can provide movement while the other hand holds a static chord. This slow section is generally in a duple meter.

The second section is generally faster and in a triple meter. Voices could enter in a fugal style (one after the other in imitation). Typically this portion would start on the Positif and could have dialogue sections where the soprano or bass would be played on the Grand Orgue.

The final section would be a return to the material of the opening of the movement, but may be very short and serve more like a coda than a true repeat of the opening.

Conclusions

I hope you have enjoyed this series on the French Classical Suite. Please let me know if you have any questions or areas where I could offer further help as you improvise your suites. If you are able and willing to share recordings of your improvisations, feel free to include them in the comments section for this post.

Improvement comes not only through practice, but also feedback. This applies not just to improvising, but also to writing. If you have suggestions for the next series or ideas for how I can help you improvise better, I’d love to hear them.

May your improvisations continue to improve,
Glenn

French Classic Fugues

As we near the end of this series on the movements of the French Classical Suite, we need to face the much revered and highly intimidating form of fugue. Before composers turned to serialism with twelve-tone rows in the twentieth century, I believe fugues represented the highest level of compositional craftsmanship. With the possibilities of stretto (overlapping statements of the subject) and diminution or augmentation, it is very easy to imagine a composer spending hours working out exactly how to combine the subject with itself in multiple ways to create a masterpiece. To be able to improvise a fugue on the with little preparation and no possibility of correction once the notes have been played makes this one of the most impressive forms to improvise.

Luckily for us, in the French Classical Suite the movements are too short to worry about or try to include many of these advanced techniques.

Exposition

At it’s most basic structure, a modern listener expects a fugue to begin with a single voice and each of the subsequent voices to enter one at a time in imitation of the original subject. The first statement provides the subject of the fugue, and the second entrance, typically in the dominant would be the answer. A real answer is a strict transposition of the subject. A tonal answer makes some modification of the subject in order to adjust for the unequal distances from tonic to dominant (perfect fifth) and dominant to tonic (perfect fourth). Most people find it is easier to improvise fugal expositions working from the lowest voice to the highest. French Classical fugues were almost always for manuals alone, so the lowest voice would be played by the left hand, enabling us to keep our improvising a little simpler by not using our feet for this movement.
FugalExpo

Development

Given the shorter time expected for most verset movements, there is not time for extensive development and modulation to multiple key centers. Some movements in the French Classical repertoire with the title fugue consist of little more than an exposition with a conclusion shortly after all the voices have entered. For a slightly longer movement, try modulating towards closely related keys with new statements of the subject clearly stated when you arrive at the new key. It is useful and important to remember in a fugue that all of the voices do not need to continue during the entire piece. Especially for modulating sequences, it can be very helpful to reduce the texture to two parts for the transition with the third voice re-entering to mark the arrival at the new key center. The best fugues seem to always have a subject or material from the subject present in at least one of the voices at all times, so be sure to keep your development focused, and make it back to tonic for your conclusion.

Registraion

Reeds provided the most clarity on the French Classical organ and so were the basis for these highly contrapuntal pieces. The Classic registration for a fugue is to use the Trompette of the Grand Orgue perhaps with Bourdon and Prestant. An alternative would be to use the Cromorne (with Prestant or Flute 4′).

The highest level of fugue in the French Classical period was probably produced by Nicolas de Grigny. His fugues were for five voices on two manuals and pedal. The right hand played two voices on the Cornet while the left hand played two voices on the Cromorne. The fifth voice was played by the pedal on the Flute 8 or Grand Jeu de Tierce coupled from the Grand Orgue. Because there is at most an upper and lower voice in each of the tone colors, it becomes easier for the listener to follow individual voices. If you have mastered fugal exposition on one manual, try the registration used by Grigny. If you need some inspiration, listen to Christophe Mantoux play Grigny’s Fugue on Ave Maris Stella.

Hoping fugues inspire you rather than send you fleeing!

Not All Solos Are for Soprano

As our ears are naturally attracted to the extremes, melodies often get placed in outer voices. The default location for a solo voice tends to be the soprano or uppermost voice. A soft gentle air will usually have the theme here. The most common exception to a soprano solo would be a rousing toccata where the extreme low end gets the theme played by our feet. Today, I want to look at two forms found in the French Classical Suite where the left hand gets the solo.

Basse de Trompette

The basic registration suggestion for a Basse de Trompette is:

  • RH (Pos): Bourdon 8′ with the Prestant 4′ or Montre 8′
  • LH (G.O.): Trompette 8′, Bourdon 8′, Prestant 4′ or Montre 8′

Depending upon the organ, a Clairon 4′ might also be added to the solo registration and the Doublette 2′ and/or Larigot to the accompaniment.

These pieces are generally in 2 or 4 beats to a measure and often start with the accompaniment alone. They may be imitative and occasionally are even titled as fugues. Most often though, the accompaniment remains simple once the bass solo begins. Whereas a soprano solo may be very lyrical with lots of motion by step, these bass solos are modeled more after pieces written for the viole de gamba with large skips. For example:
BasseTrompette

Like the other récits last week, it is possible to use other solo registrations for a bass solo. A Basse de Cromorne will have more stepwise motion that a Basse de Trompette, and a Basse de Tierce will be even smoother. Though large leaps will still appear with these other registrations, the frequency of them will decrease as the registration becomes further removed from the trompette. The tempo is also likely to slow down. Because of the activity in the solo voice, the harmonic rhythm is likely to be only one or two chords per measure. That makes these great pieces to work on if you want to practice thinking faster than you play!

Tierce en Taille

The earlier registration suggestion for the Tierce en Taille is:

  • RH (G.O.): Bourdon 16′ (or Montre), Bourdon 8′, Prestant 4′
  • LH (Pos): Bourdon 8′, Prestant 4′, Doublette 2′, Nazard, Tierce, Larigot

While the pedal is used for these pieces, no registration was specified as there would be so little to choose from on a French Classical organ. Most organs had a Great to Pedal coupler, and the only pedal stop available for accompaniment would be the Flute 8′. As the Tierce stop lost its’ strength in the 18th century, the accompaniment also lost some of its vigor by exchanging the Prestant for a Bourdon and even losing the 16′ stop(s). If a Montre 8′ was available on the Positif, it might be added to the solo and the Prestant 4′ changed to a Flûte 4′.

These movements are some of my favorite from this stylistic period. The registration is rather unique with the accompaniment surrounding the solo (written above and below, but also sounding in the same register as the solo). It was often used at the Elévation in Mass (where the priest consecrates the bread and wine – the most solemn moment of the celebration), but it also appears in other suites for verses of the Magnificat, Gloria, and other hymns. These solos are very vocal in style and highly ornamented. They should be considered like récitatives sung during the same time period, almost without tempo and with lots of freedom to explore the exquisite sounds of this registration. The Cromorne en taille would be slightly less active, but still extremely vocal and highly ornamented. These are delicate pieces so a Trompette would never be chosen as a solo here.

Left Hand Workout

These movements will encourage you to think more about your left hand. As the left hand often ends up playing in the middle of our improvised texture, it can be filler and often is mindlessly making noise. These two solo movements require that we focus our attention on the left hand, whether it is playing the lowest part of a Basse de Trompette or is in the middle as a Tierce en Taille. If you have difficulty focusing on the left hand, you could always rehearse the solo and accompaniment separately. Just like a live duo, the accompanist practices his or her part before meeting the soloist, and the soloist learns his or her part before meeting with the accompanist. Practice your left-hand solos alone to discover how to play the leaps and ornaments for these movements. Practice the right-hand (with pedal) accompaniment so that harmonically you have a support for the solo. Then schedule a joint rehearsal after each has learned his or her part!

May your left-hand solos be as creative and easy as your soprano solos!

Récits: Registration and Unwritten Expectations

Structurally, a French Classical Récit may not seem too difficult to improvise. Pull out a solo stop and a bourdon (maybe with a montre 8′ or flute 4′).  Play for a couple of minutes. Make sure you cadence in the same key you started, and you’re done. Easy, right?

Maybe so. Maybe not.

At first glance, Récits come with a variety of registrations: cornet, cromorne, trompette, nazard, tierce, hautbois, and even voix humaine. There are even movements that dialogue between two different solo registrations so that you don’t even have to limit your selection to one at a time! While many of these movements are in some form of 4/4 time, pieces with three beats per measure are not uncommon. Aside from an occasional suggestion of some snippet of a phrase from the chant, there is usually not a distinctive melodic motif or other form expected for the piece. With so many options, what makes it so difficult to be authentically French Classical?

Unwritten Expectations

About twenty years ago, I came across an article that delivered an a-ha moment for me about improvisation and also prepared me to study abroad. Unfortunately, I have no idea who the author was or where the article appeared. (Presumably the photocopy I made of it might be hiding in an unopened box from my recent move, but was likely misplaced many years ago.) The article compared improvising to learning the unwritten rules of a culture. Every culture has and teaches its members a certain set of behavior an knowledge. Most people do not realize the extent of this cultural formation until they encounter a radically different culture while traveling. 

While it is easy to accept and understand that each culture teaches its members its own set of knowledge and behavior, the revelation for me in this article was that the level of assumed knowledge varies from culture to culture. The author compared the cultures of Germany, France, the United States, and Japan. Germany demonstrated the lowest level of assumed knowledge. Germans will explain what you need to know to you clearly. If the information is important for your understanding, it will be included and explained by a German. 

Moving to a slightly higher level of presumed knowledge are the residents of the US. (I’ll call us Americans for brevity even though I recognize there are many others on this continent that can use that title and not be the group the author referred to.) As an American, I am likely to presume that my audience has some familiarity with the topic I am presenting. Ask questions, and I’ll fill in any details you need, but I’m not going to bore you with details that you may already know if I can make my point without them.

in France, a great deal more knowledge is presumed. Where an American might presume you’ve heard of an author before, the French will not only expect you to know who the author is but also when he lived, what he wrote, and something about his style or why he was influential. I was very thankful to have learned this before I went to study in France. In a practical example, if I hadn’t known there was a discounted train ticket price for students, I would have never been told or offered one by the sales agent. Presumed knowledge is not explained.

The culture with the highest level of presumed knowledge in the article was Japan. I have never traveled to Asia, so cannot verify how different this is from the other three cultures (which I have experienced). I do know there are many more cultural rules and behavioral expectations in Japan, so this hierarchy of assumed knowledge seems to make sense to me. Neither the author of the article nor I imply that any of these cultures is better than the other. They are simply descriptions that are useful to know, especially when moving from one culture to another.

From Culture to Music

Music is often called a language, so carries it’s own set of implied knowledge and structure. The French presume a certain level of knowledge that remains unstated. The title of a movement not only gives the registration, but so far has also implied a tempo and character. It’s no surprise then to discover that Récits have different characters and compositional styles based upon the solo voice chosen. If more than one option is given by the composer for the solo voice, then it is expected that the tempo and ornamentation of the piece will change with the registration. 

Here are some of the differences between the different solo stop pieces:

Récits de Cornet, Tierce and Nazard

The Récits de Cornet are the quickest of these solo movements. Ornamentation is very florid with irregular groupings of notes (5, 9, or even 10) very common. For example:

CornetRecit

 

Slightly slower than the Récit de Cornet, but still generally a lively piece the Récit de Tierce often ends with two upper solo voices. The Récit de Nazard is the slowest of these three, generally marked Largo, Andante or Tendrement (Tenderly). Clérambault is the exception with a Récit de Nazard marked Gayment et gracieusement.

Récits de Trompette, Cromorne, Hautbois and Voix Humaine

Sometimes called a Dessus de Trompette because the trompette is used in the upper voice (as opposed to a Basse de trompette), these are the most lively of the reed solo movements. The solo writing often imitates gestures played by a real trumpet, with lots of skips between notes of the same chord:

TrompetteRecit

By contrast, the Récits de Cromorne are much slower and more melodic, imitating a singer:

CromorneRecit

 

The Hautbois being a later innovation to the French Classical organ, these récits are generally quicker and more active than a récit de cromorne. They are modeled more after writing for the violin than purely vocal styles. Finally, the Voix humaine is the slowest of the récits, played in a more legato, vocal style, reflecting the name of the stop.

Immersion

The best way to speak a foreign language is to live in the country where you are completely immersed in the language and culture. Learning to improvise in French Classical style requires the same immersion with the native speakers. Just as there are accents and dialects in a spoken language, each composer will write a little differently than the next, but they will still speak the same language. Exposure and focused study will allow you to notice the unwritten expectations of the style like the differences in tempo and ornamentation between solo stops.

What musical elements have you learned through immersion? How long were you immersed before the knowledge appeared? How did you become immersed in a particular musical idiom? We have so many different musical styles available to us now, I believe it is more difficult to truly be immersed in a musical language, but I’d love to hear any immersion stories you might have.

Hoping your Récits sound truly French!

From Two to Three: Moving to Trios

One of the things I really enjoyed during my time in France was the study of harmony and counterpoint. My plan was to spend a year abroad in between my Master’s and Doctoral degrees here in the US. I loved living in France so much, that I eventually stayed for four years. Even though I had earned an advanced degree here, when I began study of harmony and counterpoint in France, I was placed in the class of first year students! 

Initially, I felt a little humiliated at having to start from scratch, but I also realized that there were some skills I could acquire and improve by starting at the beginning. All exercises were written in C or F clefs (no Treble G clef). While I had learned to read these clefs in school, I figured it wouldn’t hurt to become even more familiar with them.

Clefs

One of the other distinctions was that exercises were always done with pencil and paper at a desk. No keyboard (or other instrument) allowed. This forces you to hear inside your head and know what the little dots on the page actually sound like before you play them. It is possible to write lines that look great on the page and may even follow all the rules but actually sound very bad. In all my studies in the US, I do not believe we were ever denied the opportunity to check our work on a keyboard before turning it in. Believe it or not, work with pencil and paper can actually be ear training work!

From Two to Three

Have you tried to improvise any duos yet? How successful were you in creating two independent voices? My entire first year of counterpoint in France was spent writing in two voices. To truly master these contrapuntal styles takes lots of practice.

The great joy of improvising a suite is that no movement needs to be very long. Use any opportunity you have to improvise in the two part texture, even if it is only for a 15-30 second interlude or coda where you need to cover some liturgical action with music. Even if the registration is not from the French Classical period, practicing in two voices will help you become more familiar with the texture and gain fluidity. While you may not want or need to spend a year on two-part texture as I did in France, the more comfortable you are with two voices, the easier it will be to move into three parts.

Trio à Deux Dessus

There are two types of trios in the French Classical suite. The simplest to begin is the Trio à deux dessus (with two upper voices). As with the Duo, in this Trio form, the voices are generally imitative and enter one after the other, most typically from high to low. The top two voices are played with the right hand and the lower voice with the left. As with the Duos, these pieces tend to be in a triple meter, though usually with a slower implied tempo than the Duos. (Perhaps this was so the improvising organist could take a little more time to think when managing the three voices!) This doesn’t mean that they were slow, just not as fast.

Registration

The most common registration suggestion for the Trio is:

  • RH (Pos):  Cromorne
  • LH (G.O.): Tierce, Nazard, Quarte de Nazard (2′), Bourdon 8′, Prestant 4′

Other options include:

  • RH (Pos):  Tierce, Nazard, Bourdon 8′, Prestant 4′
  • LH (G.O.): Trompette
or
  • RH (Pos):  Tierce, Nazard, Bourdon 8′, Prestant 4′
  • LH (G.O.): Clairon, Bourdon 8′, Bourdon 16′ Prestant 4′
or for smaller instruments, Lebègue suggests the same registration as the duo:
  • RH (Pos):  Tierce, Nazard, Bourdon 8′, Prestant 4′
  • LH (G.O.): Tierce, Nazard, Quarte de Nazard (2′), Bourdon 8′, Bourdon 16′ Prestant 4′

One of the more interesting registration suggestions by Gigault is to use the Tierce of the Grand Orgue for the upper and lower voices while playing the middle voice with the thumb on the Cromorne of the Positif! This would definitely require practice and is not necessarily well-suited to all trio textures. 

Trio à trois claviers

The other Trio voicing has each voice on a different keyboard. While there are a certain number of pieces written that require three hands to play, I’m not sure these are within the realm of an improviser. Even though I have done some joint improvisation, asking someone to improvise a third voice in a strict contrapuntal style would require some real practice and perhaps some other agreements about form and structure in order to have any chance of success.

The great thing about being an organist is the ability to use our feet to play a (pedal) keyboard. French pedalboards of the time were primitive by today’s standards, so the bass voice of these trios is likely to be slower moving than the other voices. Grigny pushes the technique of the organist by providing several measures of eighth-notes in one of his hymn suites. 

In general the registration for these trios with pedal looks very much like the registrations above but with an 8′ Flute in the pedal. On organs where there was a pedal coupler, it was also possible to use the Jeu de Tierce from the Grand Orgue in the Pedal. 

Advice

Unfortunately, I don’t have a lot of guidance to give you for the best way to improvise a trio. Trios are the sorts of pieces where written contrapuntal studies become extremely useful. Choosing a short motif and making sure to pass it frequently from one voice to another would be a good mental focus when improvising a trio. It could also be helpful to practice improvising two voices alone with the right hand. Study the repertoire. Write out your best ideas and turn them into sequences and transpose them into other keys or modes. Above all else, practice slowly so that you have time to think (and hear) before you play.

While I believe it is easier to begin with a Trio à deux dessus, you may have an easier time with a Trio à trois claviers. Is it more complicated to add in an extra voice (with the hand) or an extra body part (the feet)? I’d love to hear which of the two is easier for you. 

Hoping the joy of improvising increases with every voice you add,

Glenn

The Second Part: Duos

In the French Classical suite, after the opening Plein jeu which primarily explores interesting harmonies, the second movements are often more contrapuntal in nature. Rather than jump into a Fugue, we’ll stick with the simpler Duo. Out of 55 Magnificat settings surveyed by Jean Saint-Arroman, 41 have a duo as the second verse.

Registration

The registration for the Duo varies quite dramatically by the end of the French Classical period. Early registration suggestions include:

  • RH (Pos):  Tierce, Nazard, Bourdon 8′, Prestant 4′
  • LH (G.O.): Tierce, Nazard, Quarte de Nazard (2′), Bourdon 8′, Bourdon 16′ Prestant 4′

or

  • RH (Pos):  Tierce, Nazard, Quarte de Nazard (2′), Bourdon 8′, Prestant 4′
  • LH (G.O.): Trompette with a foundation stop

By the end of the 18th century, other reed stops (Hautbois, Basson, Cromorne, Voix humaine) begin to show up as options for both voices. In a modification of the first option, Dom Bedos even offers the choice to use the 32′ stop for the left hand along with the tierces and nazards!

 

Tempo

Most Duos are in the form of a gigue, so tend to be faster, lively pieces in triple meter. The following rhythm is very common:DuoRhythm

In order to keep the piece light and active, some composers even double dotted the quarter note.

While most Duos tend to be fast, there are a few, generally in a duple meter, that would be in a more moderated tempo. Somehow, I can’t imagine playing quick double dotted rhythms with the 32′ stop Dom Bedos recommends, so the registration of the piece should also reflect the style and tempo.

Creating a Duo

As hinted above, Duos have a more contrapuntal nature. The left hand generally enters after the right hand in some sort of imitative gesture. Parallel thirds and sixths are very common, and hemiolas often appear at cadences. Any study of counterpoint usually starts with writing for two voices and would be most helpful before improvising a Duo.

The opening right hand gesture typically serves as a thematic motif for the piece and is usually about two measures long. Here are some basic steps to help you move from a motif to a full piece:

  1. Choose a motif with distinct rhythmic and melodic characteristics
  2. Practice the motif in both hands (one at a time) in multiple modes and keys
  3. Choose a tempo and play the motif with alternating hands in tempo (like jazz players trade solos every four bars)
  4. Use sequences of the motif (stepwise or circle of fifths) as you alternate hands
  5. Explore counterpoint for your motif. Can you play it in thirds? Sixths? What makes a good bass line for it?
  6. Repeat the process of alternating the motif between hands, but feel free to add in the second voice using the contrapuntal ideas you have found
  7. After so much exploring, it’s time to improvise a piece from start to finish. Fill in with extra material as needed. Make sure you visit one or two other key centers and bring the piece back to a satisfactory close in the tonic. 

If you have not studied counterpoint, it might be helpful to plot out and notate some of your ideas. Just as an infant learns to walk while holding on to a helping hand or other object, there’s no reason not to write a few things down to serve as our support as we learn to improvise. Even writing an entire piece could be helpful.

Duos are to be lively and fun pieces, so make sure your improvisations are joyful this week!

The French Opening: Plein jeu

In the French Classical period, composers wrote suites of pieces that were used in alternation with the choir. The choir would sing a verse of chant and the organ would play a verse, trading with each other until the entire chant text had been proclaimed. Except for the Gloria during Mass, the organ would generally play the first movement in order to establish the mode and pitch for the choir. The first movement might also clearly cite the theme as a reminder for the choir of the melody that they were about to sing.

Modes

Gregorian chant was the primary source of liturgical music during this period and was considered to be in modes rather than our modern major and minor keys. There are eight chant modes commonly referred to as:

  1. Dorian (D-D)
  2. Hypodorian (A-A)
  3. Phrygian (E-E)
  4. Hypophrygian (B-B)
  5. Lydian (F-F)
  6. Hypolydian (C-C)
  7. Mixolydian (G-G)
  8. Hypomixolydian (D-D)

The easiest way to describe these tonalities is using the white notes of the keyboard for the ranges listed next to the names above. While this is a vast oversimplification of the use of modes in chant, it will give you a basic idea of how each mode has a different character. 

These modes could be transposed to other pitch centers to make it easier for the choir to sing the chants, so while you may not need to know how to play every mode starting on any pitch, in order to improvise in the French Classical style, you definitely need to know the modes. The links above and last fall’s newsletter on learning modes are places to start if you need more of an introduction.

Registration and Style

The classic plein jeu registration is:

  • G.O. (Great): Bourdon 16′, Bourdon 8′, Montre 8′, Prestant 4′, Doublette 2′, Cymbale, Fourniture
  • Pos (Choir): Bourdon 8′, Prestant 4′, Doublette 2′, Fourniture, Petite Cymbale
  • Péd: Trompette 8′ (if used)
  • Keyboards coupled

The pedal trompette is quite a loud stop compared to the typical pedal trumpets on most American organs. Take advantage of all the videos on YouTube to listen to some of the historic instruments like Poitiers, St. Maximin, or even the restored Dom Bedos in Bordeaux if you haven’t gotten to hear these sounds live and in person.

Most often these opening movements are in cut time with two slow half note pulses per measure. The writing is often in four to six voices. If there is a chant theme, it could appear in the bass or tenor. According to Dom Bedos:

Le grand plein-jeu doit se traiter gravement et majestueusement, l’on doit y frapper de grands traits d’harmonie, entrelacés de syncope, d’accords dissonant, de suspensions et surprise d’harmonie frappantes.

The great plein-jeu must be treated gravely and majestically. There one must make broad strokes of harmony, entertwined with syncopations, dissonant chords, suspensions, and striking harmonic surprises.

One of my favorite harmonic progressions from this period is where the bass makes a deceptive resolution from V to vi while the other voices resolve to a major tonic chord. For example, in A minor:

DeceptiveCrunch

Especially in the earlier not so equal temperaments, this is definitely a striking chord progression!

Form

Unless there is a theme present, many times these pieces simply seem to wander through chains of interesting harmonies in the tonic or closely related modes. Themes tend to be in half notes in the pedal, usually in the tenor, but occasionally  in the bass. Looking at a standard harmonized hymn and placing the melody in the tenor played by your feet requires practice. While not my best improvisation ever, I did manage to record a short plein jeu on Tallis’ Canon this week as a demonstration of the style and so you could hear the organ at the Cathedral. Feel free to share your own improvised plein jeu performances in the comments for this post.

The French Suite

During the Baroque music period, French organists developed a style of playing and pieces that has become known as the French Classical School. Notable composers during this period include:

Before improvising in a style, it is always a good idea to play as many of the written pieces as possible. Scores from these and other composers from the era are available from IMSLP. While there will be differences in the pieces between composers, by playing through a large part of the repertoire, it becomes easier to identify the common characteristics of the style.

Movement types

Whether written for use with a hymn, movements of a mass, or for the Magnificat, French Classical composers created suites of pieces, often titled by the expected registration or texture of the movement. The most common movements include:

  • Plein jeu
  • Fugue
  • Duo
  • Trio
  • Récit
  • Grand jeu

While the order and number of interior movements varies, the suites almost always start with a Plein jeu and end with a Grand jeu. In the category of Récit, I am including movements that feature a solo stop and accompaniment such as Tierce en taille and Basse de trompette. Don’t worry if these titles don’t mean anything to you for now. I plan to spend the next few weeks explaining each one individually, offering comments on the style, registration, and steps we can take towards improvising these different pieces.

In the meantime, go find (or download) some scores to play through and enjoy this audio clip of one of the current French masters, Michel Chapuis, improvising in French Classical style for your inspiration:

Hoping you will find inspiration from the French Classics,

Glenn
