Bass sarrusophone

The bass sarrusophone is the bass member of the sarrusophone family of metal double reed conical bore wind instruments. Pitched in the key of B♭, it has a range almost identical to the bass saxophone, and can cover the bassoon range up to F$4$.

Historically it was built in the late 19th and early 20th centuries principally by its inventor Pierre-Louis Gautrot and his successor PGM Couesnon, as well as Evette & Schaeffer and Orsi of Milan. It is currently only available by custom order from Orsi.

There is very little repertoire specifically for bass sarrusophone; Roupen Shakarian has written a piece for it called Sarruso Rex.
