Single Horn with 3 valves "modèle Liégeois"
F. Van Cauwelaert Breveté à Bruxelles, ca 1900

From appr. 1890 onwards, the second generation of  the Van Cauwelaert family (also known as “frères et soeurs”) developed a second horn model next to the existing “Gantois” model. This instrument, based on the French “cor-solo” design had a lighter and more agile sound an was named the “Liégeois”-model because of its success with players from the class of Mathieu Lejeune at the Liège conservatoire.

The horn has a fixed leadpipe, and had tuning slides of different lenghts in order to change the tuning from F to Bb alto.
It is a rare example of an instrument that, with exception of the valve block, is constructed in an entirely conical way (also the tuning slides are conical!). It showed itself particularly usefull  for playing Bruckner and Wagner with the Orchestre des Champs Elysées, for “Carmen” with les Musiciens du Louvre, for “the Rite of Spring” with the Kölner Akademie, for the octets of Du Bois and is intensively used in the Lyrical Style project.
The horn has crooks for F, A flat alto and B flat alto.
