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

Making a cello

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!

Making varnish for violins

Violin varnish © Ch. Dequincey -Rsz2The 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.

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!
