For me the 2021 year was a time of transition, growth, fresh energy, and new directions. After 14 years working for Guy Harrison in Ottawa, I moved to Boston in April to start working as a full time restorer for Reuning & Son Violins. It’s an honor to be part of such a fantastic and knowledgeable team, and I am excited to be working on many fine instruments at the shop. I continue to build my own instruments independently, right now I am working on two cellos.
Another highlight of 2021 was being voted into the American Federation of Violin and Bow Makers. The Federation has strict requirements for membership, admitting only those who pass its rigorous standards of workmanship and ethics. In order to be considered for membership in the AFVBM, a maker must present their work to a panel of judges. At their September meeting in Los Angeles, I presented my latest violin, an instrument modeled after the “Ysaÿe” by Guarneri Del Gesu. Not only am I proud to have been voted into the Federation; I am also happy that the violin I presented to them soon found a home with a musician in the San Diego Symphony!
Last November, I was pleased to finish a cello in time to
participate in the 23rd International Violin making competition held
by the Violin Society of America (VSA) in Cleveland.
Among the 68 cellos presented, my instrument was awarded a Double Certificate of Merit :
-a Certificate of Merit for Tone by judges and cellists Dane
Johansen, Jeffrey Solow and Brian Thornton.
-a Certificate of Merit for Workmanship by judges and violin
makers Ulrike Dederer, Antoine Nédélec and Raymond Schryer.
It was a great achievement and honour to be rewarded for my work in this way. For a violin maker it is significant and meaningful to receive such distinction at this international level and to see the results of years dedicated work acknowledged and encouraged.
This event is also an excellent opportunity to acquire a
representative overview of global contemporary instruments which were, in my
opinion, quite remarkable in quality. It
also gives to participants the opportunity to discuss their individual work
with the judges. Thank you and congratulations to everyone who took part in it!
I also wanted to personally thank Paul Marleyn, Rachel
Mercer, and Raphael Weinroth-Browne for their time and useful feedback while
adjusting the cello.
This 2018 Dequincey Cello has a body made of Canadian poplar and spruce. The maple neck and pear wood scroll are sourced in Europe.
2018 has ended and it has been quite a busy one! Among other things, I’ve been taking part in the 3D StringTheory Project presented by the Ottawa Symphony Orchestra last November. This multidisciplinary project involved the conception and production of a 3D printed ‘’da braccio’’ octet as well as the composition of a musical piece for the resulting instruments.
With the help of digital designer Laurent Lacombe (Co-founder of Creadditive, Québec City), we adapted the model resulting from a CT scan of a Dequincey violin that I provided for reference. We worked as well with Myron Semegen (Industrial Technology Centre, Winnipeg) to have a better understanding of the thermoplastic materials and printing options available at the Centre.

The focus of our team was to make instruments as
light as possible while still being able to withstand the string tension. For
the musicians, they had to be pleasant to hold and play, and capable of
producing the most agreeable sounds possible. The main challenge was dealing
with the printing materials which had properties almost opposite to wood in terms
of stiffness and density.
At the beginning we weren’t sure what to expect. However, if people had managed to perform popular music on wood shoe-violins, do-it-yourself violins and cellos in the trenches during the First World War, or on repurposed trash as depicted in a recent documentary (http://www.landfillharmonicmovie.com/), I thought it should be possible to build an instrument with which one could play music.

From my curious and experimentalist perspective,
it was quite interesting to go through the experimentation process of adjusting
my experience with wood to aim for as good an end result as possible, within
the time constraints. I wish that we had had a bit more time to explore a few
more ideas.
The final instruments are heavier than traditional violins and violas. They also required a fair amount of finishing by hand before the set up and sound adjustments. It appears to me that the sound produced by the instruments seems to be perceived more loudly by the player than it effectively projects in a larger space, probably due to properties of the material using a traditional violin shape. If this defeats the goal of big scale performances it might be advantageous for other purposes. However, on the day of the performance the instruments had to be amplified so as not to be overtaken by the orchestra.

Before doing some final adjustments on the instruments, I was able to hear one of the last rehearsals of the octet. I very much enjoyed witnessing the eight musicians and composer Harry Stafylakis working together on the textures that the instruments could bring to the piece. I couldn’t help being amazed by the overall final results in tone which were well beyond my expectations.
This experience increased my understanding of the current possibilities and limitations of CAT scanning, 3D software and 3D printing. These technologies have the potential to be useful in several areas of my profession such as the restoration and study of historical instruments.

As for the future of 3D printing in general, I
can’t
help but be concerned by the environmental costs of producing, recycling and
disposing of the thermoplastic materials used. Also, in a world where
obsolescence is frighteningly setting in as a norm, one might want to consider
the durability of these materials and the ease/safety of repairs to extend the
lifetime of a finished object.
Working with these synthetic materials increased my appreciation for the versatility of wood, and I contemplate the utopian vision of forest’s sustainability, slow growth, preservation of diversity resulting in better quality and choice of wood, both for instruments and other uses. I fear that climate change, among other challenges, will make it difficult to go in this direction.
Also, as we already know, ebony is another problematic wood not only because of its scarcity, but also because of the decreasing quality, due to various exploitative abuses of forests. I looked for new options for fingerboards and was able to identify new composite alternatives, already in production, available for violin fingerboards. These fingerboards look similar to ebony and are easy to work with. The composite material is more durable than ebony and resists normal wear. This would decrease the need for the fingerboard planing, which is a financial incentive for musicians. At the time of writing there are a few other options available. I’ll try to write about this in a future blog post.
I would like to thank the Ottawa Symphony
Orchestra for facilitating this project, specifically Angela Schleihauf our
project coordinator, the Canada Council for the arts for their financial
support, as well as ITC and Creadditive.

process here are a few links to a series of short videos made during the
project:

I wanted to extend my warmest thanks and share with you some highlights from my experience gained through the Chalmers Professional Development Grant, which was granted to me by the Ontario Arts Council in 2015.
The grant allowed me to attend this year’s violin making workshop in Oberlin, Ohio for two weeks. There, while working on a violin, I was able to attend great lectures given by colleagues coming from all over the world and discuss various making techniques and the latest technological developments. Additionally, I had a chance to study the Jackson Stradivari violin (1714) and I was able to show my work and discuss it with my peers.
I also went to Sault-Ste-Marie for one week of study with Raymond Schryer in the fall. We discussed the use of wood, in particular Canadian species and studied the classical design and arching of Stradivari’s golden period (in particular the P form). I got to see and use his methods of making, which was a very valuable experience for me.
Those experiences allowed for me to see many different approaches and consider ideas which in future years can only be beneficial to my work as a violin maker. Thanks again,
“Very nice cello, with a handsome varnish. The sound is well balanced with a deep and strong C string, which can be difficult to find in a cello. I also like the width and projection of the A string sound.”
Paul Marleyn, Professor of Cello at the University of Ottawa
A musical instrument such as a violin, viola or cello is the result of an accumulation of decisions from its conception (and wood choice) to its set up including the design of its outline, proportions, arching shapes, distribution of thickness, sound hole placement/shapes, neck measurements, etc. Despite certain standardizations created by the historical evolution of the instrument, we are still left with a relatively large range of choices.
Before starting an instrument, it is quite important for me to define clearly what I want to achieve in terms of sound, comfort of playing and style. This helps me to determine what model of instrument I’ll be working from. I then decide how much freedom I’m going to take with the entire design: if I’ll base it on a particular instrument or maker, or if I’ll just work from a general feeling of a violinmaking school/period and create my own outlines.
I personally fancy the dark and deep quality of the lower register in quartet instruments, so when I got access to a source of poplar big enough to built cellos, I thought it would be perfect since poplar has a reputation for creating a darker sound in violas and cellos. While I was researching more about it, it also seemed to be associated with quieter instruments. I thought this would make an interesting challenge: to try to get both projection and depth in the lower range of a cello.
With this goal in mind, I picked a model with proportions that would serve this purpose, while also ensuring that the body measurements remain in a standard range that would be comfortable for a cellist to handle. Of course, the overall look is also quite important to me and was taken into consideration. From this starting point, all subsequent decisions were based on previous experience making cellos, observations I gathered working on older instruments as a restorer and influences from publications on related topics. One source of inspiration that was particularly helpful was Frank Ravatin’s talk entitled ‘’Cello making, models and measurements’’ given in November 2004 and published in the Vol. XX, No3 of the fall 2006 VSA journal.
One might never know, but some unexpected exceptions to what we thought was the rule might bring us to revise all our conceptions, and such it is the exciting learning curve of a violin maker’s journey. I’m generally quite curious before playing an instrument for the first time, and especially when trying a new model! Did the elements come together as expected? I was quite pleased with the results of this last instrument.
As a limited cello player, I felt very lucky to get feedback from professional cellists performing in Ottawa. I would like to thank them all warmly for it. As a maker working for and with musicians, it is essential for me to stay in touch with their needs and variety of tastes. Therefore, after benefiting from their experience, I was able to make some final adjustments on what turned out to be a very fine instrument!
The warm season is the ideal time to prepare varnish as it is better to be outdoors to cook the ingredients. I wouldn’t recommend that anyone experiment in their kitchen as there are too many ways it could go wrong, starting with strong and persistent resin and linseed oil smells in the best case scenario.
The varnish I use for my instruments is a mixture of drying oil, cooked rosin and thinner. I’m using ingredients, like linseed oil and colophony, known to be accessible in Europe at least 400 years ago, and were used by painters. The delicate part of preparing oil varnish resides in the cooking: it is important to use the right temperatures; the right amount of time; and the proper ratios to obtain the desired hues and properties. The layers should cure within a reasonable waiting time, and have the desired texture and transparency. Of course, regarding the colouring there are different ways to adjust it later by adding some finely ground pigments for example.
I also enjoy experimenting with the products. It allows me to explore their range of properties and get more acquainted with the results that can be obtained. This provides me a better understanding and control in the resulting product.
This year I’ve been incredibly lucky to be able to work with an outdoor laboratory ventilation hood within an inspiring country sight. I want to warmly thank Mo for making this happen, his family for their welcome and Devon for his chemistry advice.
In the last decades analyses of Stradivari’s varnish have been published, some of the most recent ones confirm the use of several materials.
-Two articles related to the study driven by la Cité de la Musique in Paris:
Cellos or Violas made with poplar or willow backs have a reputation for having a warm sound. These wood species were used throughout the history of violin making, and particularly in Cremona during the second half of the XVII century and the first half of the XVIII century. In his book, “The Secrets of Stradivari,” Simone F. Sacconi mentions that two fifths of Stradivari’s cellos still remaining, feature poplar or willow backs. There are fine examples of those instruments in the collections of the Royal Academy of Music in London and at the Library of Congress in Washington DC.
A few years ago, I acquired some pieces of Canadian poplar which were quarter sawn for violin making use and big enough for a cello. Guy Harrison and I had built in 2009 a cello using European poplar, resulting in a very satisfying sounding instrument. As I was curious to try this other kind of poplar on a cello, I built one. In fact, the spruce used for the blocks and the front also came from Canadian forests, making the body of this instrument entirely Canadian sourced!
To work with a different wood than the more common maple required that I take into consideration the differences in mechanical and acoustical properties. Accordingly, I adjusted the thicknesses in relation to the density of the wood. Then I measured the tap tones and weight, in order to adjust the final stiffness of the back as a free plate, using Nigel Harris’ method.
Some instruments with poplar/willow back features ribs made in a different wood than the back, such as ash or beech, matching the scroll. I used poplar for the ribs to match the back, and reinforced them with linen (a method also employed by Antonio Stradivari).
Je suis heureuse d’annoncer que je participerai au Forum des fabricants organisé par la maison Wilder & Davis à Montréal le samedi 6 décembre. Ce sera une bonne occasion de revoir des collègues et de présenter au public montréalais un violon 7/8ième et un alto de ma facture.
Au programme également, un concert du « Quatuor d’occasion », un récital en duo composé d’Andrew Wan et Jonathan Crow, suivit d’une démonstration de sonorité avec Frédéric Lambert.
Passez nous voir!
