This instrument closely resembles the modern Buffet system bassoon layout with 22 keys. This style of instrument is less popular today, with most of the world favoring the German Heckel model of bassoon, but is still used in areas of France, Canada, and some other romance countries.

In comparison to the Heckel style bassoons, the French models are quite simplistic in design and are sometimes said to have more expressive tonal qualities. They can reach higher registers more easily and with less air strength than German bassoons, also possessing a distinctive, sharper tone favored by many French composers but criticized by some for having a somewhat invasive presence.
