Lorenz Viegener
Passionate piano maker

Having grown up in Germany, I am an experienced piano-making craftsman who honed my expertise over my years at Pianovum Klavierbau in Düsseldorf. Trained at the Oscar-Walcker-Schule in Ludwigsburg with distinction, I master every aspect of the repair, maintenance and renovation of pianos, whether upright or grand, from various renowned makers such as Steinway & Sons, Bösendorfer or Bechstein.

Keen to continuously broaden my skills, I completed numerous placements with prestigious makers such as Steinway & Sons, Steingraeber & Söhne, Schimmel and Renner. I also undertook many training courses, winning first place in the annual BDK tuning competition for apprentices in Germany in 2019. After 5 years as a technician and team leader at Pianovum, I chose to go independent in 2022 in Lyon.

Here I now work with pianists, shops, makers, insurers and music schools across the Lyon region and beyond. My expertise allows me to work to a high standard on all types of pianos.
