Clarinet

clarinetclarinetsclarinettist
The bass clarinet is a musical instrument of the clarinet family.
Since the middle of the 19th century the bass clarinet (nowadays invariably in B but with extra keys to extend the register down a few notes) has become an essential addition to the orchestra.

Saxophone

While Adolphe Sax imitated its upturned metal bell in his design of the larger saxophones, the two instruments are fundamentally different. While the bass clarinet has been used often since Dolphy, it is typically used by a saxophonist or clarinetist as a second or third instrument; such musicians include David Murray, Marcus Miller, John Surman, John Gilmore, Bob Mintzer, John Coltrane (to whom Dolphy's mother left some of Dolphy's instruments including his bass clarinet), Brian Landrus, James Carter, Steve Buckley, Andy Biskin, Don Byron, Julian Siegel, Gunter Hampel, Michel Portal, and Chris Potter.
Prior to his work on the saxophone, he had made several improvements to the bass clarinet by improving its keywork and acoustics and extending its lower range.
