2021 Year of change.

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.

In August of last year, The Strad published an article I wrote about methods of recording arching curves using a dental compound. The article is an extension of a presentation I gave at the VSA Violin Makers in Oberlin in June 2018. You can read my article here: https://www.thestrad.com/lutherie/recording-arching-profiles-ahead-of-the-curve/13284.article

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!

Cello Awards

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.

3D StringTheory Project

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.

For those wishing to know more about the full process here are a few links to a series of short videos made during the project:

Maker’s Forum in Toronto

Last Saturday I was honoured to be part of the Maker’s Forum exhibition in Toronto. Contemporary violin makers and bow makers from Canada (34 on 37 participants) and abroad  were presenting their work. As a maker, this event was a great way to meet with musicians. I was able to discuss the instruments I had brought (a cello and a violin) and get their feedback.

During the afternoon, Kerson Leong performed on the 24 new violins exhibited. As part of a sonority test, Leong played the same excerpts on each one of them. He masterfully realized this challenging task, in my opinion. He was able to adjust wonderfully to each one of the instruments, performing over their full register. Interestingly, Leong’s consistent and methodical approach,   brought to life the individual qualities and character of each violin.

This experience was followed with a chamber ensemble, set up for the occasion, performing a Mozart quintet in C Major. The ensemble featured on violin: Jonathan Crow (Concertmaster of the Toronto Symphony Orchestra) and Kerson Leong ; on viola: Theresa Rudolph (Assistant Principal Viola of the Toronto Symphony Orchestra) and Madlen Breckbill ; on cello : Joseph Johnson (Principal cello of the Toronto Symphony Orchestra).

At the last minute some of the musicians decided to switch instruments between movements, using instruments from the exhibition. The change of colour with the different settings was quite noticeable, a good way to show how the choice/matching of instruments can affect the dynamic of the voices within an ensemble. After the exercise, I was honoured to learn that my 2016 Plowden/Del Gesù model violin was among the instruments selected to perform on.

Overall the event was well attended and quite a success. It was also a chance to see and catch up with peers. The standard of work was very high, and this made me proud to be part of it. 

I’d like to warmly thank the organizers for all their coordination work : Elizabeth Barbosa, Fany Fresard and Emanuel Euvrard.

A Thank You to the Ontario Arts Council

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,

Charline Dequincey

Poplar cello

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!

Cello patchesTo 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).
