On 2 April, an evening event organised by Talents & Violon’celles was held at the Bibliothèque musicale La Grange-Fleuret, bringing together a group of patrons for a unique, accessible and lively talk on new approaches to instrument restoration.


Dedicated to fine musical instruments, this event highlighted the specific challenges associated with their conservation and preservation. Presented by Martin Hirsch and led by the instrument makers Roland Houël and Joël Klépal, from the Houël & Klépal fine restoration workshop, it struck a balance between scientific rigour, the sharing of expertise and musical performances.

Fine Instrument Making: From Centuries-Old Craftsmanship to High Technology

Speaking to an audience of particularly curious patrons, Roland Houël and Joël Klépal offered a behind-the-scenes look at their work. They emphasised that their primary mission is to preserve the genius of the great master luthiers, whilst ensuring that these historic instruments continue to thrive in the hands of musicians.

At the heart of the event, the speakers outlined what might be called ‘instrument making 2.0’, where technological advances enrich, rather than replace, traditional craftsmanship. Far from detracting from the luthier’s craft, these tools offer a more detailed understanding of historical instruments, enabling better diagnosis and opening up new possibilities for intervention and restoration. Among these approaches are the use of monochromatic light, X-ray micro-tomography, documentation and diagnostic tools, structured light 3D scanning, and computer numerical control (CNC) milling machines, all of which provide concrete examples of how practices are evolving.

The presentation was punctuated by questions and comments from the very attentive audience, reflecting the interest aroused by these new cutting-edge methods and the challenges they raise: how to intervene without betraying the instrument’s history and identity, and how to preserve it whilst breathing new life into it. These were all questions that lay at the heart of this meeting.

As for Suzanne Wolff, she played a bass violin made by Roland Houël, which has recently been added to our early music department and is available for loan.

The discussions continued over drinks in a relaxed atmosphere, giving guests the opportunity to explore the topic of new restoration techniques for high-end instruments in greater depth.


Guests were also able to take a closer look at the Stradivarius violin on display in a showcase – an exceptional instrument currently being restored by Roland Houël and Joël Klépal – as well as the Maggini viola dating from 1600, played by Léa Hennino. As this instrument had undergone a detailed analysis before being put up for sale, it attracted considerable interest.
