About me
I am a married father of four, and an engineer with a master's degree in engineering and another in computer science; I also graduated in 2007 from the Conservatoire of Cergy-Pontoise, France, with a 3rd cycle degree (9-year studies starting in middle school) in Baroque and pre-Baroque music interpretation. I discovered Gregorian Chant and the traditional liturgy in 2005. I have served as a master of ceremonies, then as a cantor, in both forms of the Roman rite, in various parishes from 2015 to 2022. Since 2022, I head the Schola Saint-Aignan, that serves the FSSP (PFSP) parish in Chartres, France; since 2025, I also serve as music director for that parish, coordinating the choirmasters, cantors, organists and priests.In 2017, I joined the board of Esprit de la Liturgie, a French non-profit that publishes resources for liturgical formation across various media. Here are my articles on Esprit de la Liturgies (in French).
In 2018, I published a (peri-)liturgical book for the first time, a Latin-French edition of the Little Office of the B.V.M. according to its Tridentine order, with a versified translation by French playwright Pierre Corneille. In 2021, I discovered the singing of the hour of Matins, thanks to French musicologist Dominique Crochu, among others. Since then, I head the Nocturnale Romanum Project which aims to publish all liturgical books necessary for the solemn celebration of this hour of Divine Office.
Throughout my STEM studies, I developed something of an expertise in how to embed liturgical material in LaTeX documents; since then, I used the GABC and NABC languages extensively, and contributed (in a very minor fashion) to the extension of the NABC neumatic description language.
Today, I offer this experience to other choirmasters, music directors and publishers who wish to create their own resources for liturgy and chant.
Lessons
Tuesday nights, "in real life"
On Tuesday nights, I lead a free Gregorian Chant workshop in Jouy (Eure-et-Loir, France), where, depending on participants, we lean to sight-read, work on vocal technique, on interpration, or study modality, neumatic notations, or the history of the chant repertoire. This workshop is mainly aimed at the Schola Saint-Aignan, but is open to all.Video lessons
I am available on demand, most nights from 9pm to 11pm Paris time, to discuss chant typesetting, to teach how to use the related tools, how to write in the related programming languages, how to implement the related processes, how to manage a chant book project, and to answer any related questions. My prices depend on the topic, the number of participants, etc.— please contact me.Consulting
You want to publish a simple leaflet for that one time where your parish will sing chant? A bound booklet for your Sunday Vespers? A choir book for your community? A commercially-viable liturgical chant book for general use? I can advise you on the different ways to go about such a project, having done all of those things, and more, throughout the last decade, for Mass as well as Divine Office, and for the Extraordinary and Ordinary forms, as well as the Monastic Office.I am currently consulting on two major editorial projects, with room for one or two more. Do not hesitate to contact me. Depending on the nature of your project (commercial or not, etc.) adequate compensation will be discussed.
Resources
The GABC/NABC + LaTeX software stack is not easy to learn, and even after learning it, it is not easy to use. But you are not alone:- A lot of scores (and most of the more useful ones) are already transcribed on Gregobase.
- You can ask questions and get help on Gregorio (excluding preview tools like Chant Tools, scrib.io, etc.) on the Gregorio mailing list.
- Reading the code of an existing project could help you get ideas for your own; you can even fork it and fit it to your needs. See my small collection of single-use booklets and leaflets, and as far as more ambitious projects go, this example of bilingual booklet for the 2025 Rencontres Grégoriennes, the several volumes of the Nocturnale Romanum, Matther Roth's Vesperale Romanum, or br. François Petitjean's Vesperale OP.
Tutorials
As part of liturgical formation provided by Esprit de la Liturgie, I published in 2021 a series of French-language tutorials for GABC+LaTeX. These tutorials are not entirely up to date, but they are still relevant, and the prerequisite for my (French-language) lessons. As far as English goes, I think reading and understanding the docs on Gregorio, as well as a basic LaTeX tutorial, does most of the heavy lifting for getting into chant typesetting.
