There are 2 Buffet Contrabassoons for sale on Musical Chairs. These are contras built with the french fingering system and a different bore than a Heckel system contra. They appear to be in great condition and I’m sure will sell quickly. This is the instrument intended for in the works of Debussy, Stravinsky, and Ravel.
Les Siècles performed Rite of Spring using period instruments at the BBC Proms. The bassoon section uses old french bassoons and tall construction french contras.
