Record
Each instrument that leaves the workshop carries a history: a commissioner, a musical intention, a wholly crafted piece of work. These completed works are the concrete trace of an uncompromising standard.
Instrument · 01 — The Walter series
The very first Walter fortepiano built at the workshop. A challenge set by a concert pianist started everything — and led to an album recording, proof from the very first work that the instrument was equal to the professional stage.
Capsules, hammers, action, keyboard — built entirely in Guebwiller.



Fifth work in the Walter series. Each instrument refines the mastery of this exceptional Viennese model a little further — Opus 5 marks a milestone in the series, with a concert film produced around this instrument.
The Walter series today numbers more than ten works, all built entirely in Guebwiller.



Instrument · 02
Square piano of 1815 — an instrument at the crossroads of two eras, of rare musical sensitivity. Currently under construction, destined for a conservatory. Full photographs and specifications upon delivery.

above all I seek the beauty of sound.”
