Re: Bass Clarinet Technique; Is 'Slightly Lifting Off' A Thing? ...

As they're primarily a sax player and the left thumb only controls the 8ve key (and low A key on bari), the left thumb can pretty do what it wants on saxes without having a tonehole to cover on them. Same thing with conservatoire system oboes with no added thumbplate. Only that doesn't apply to bass clarinet as the left thumb has to remain on the thumbplate for the majority of the time.

The only adjustment I can allow for in the region of the LH thumb and LH1 is the venting of LH1 and the adjustment between LH1 and the open G vent. The LH thumbplate will always have to close the open G vent no matter what. Adjusting the venting of LH1 will create some lost motion in the linkage between the LH1 thumbplate and the open G vent which can reduce mechanical noise which may occur when doing an F# to open G trill. I have on some occasions added a nylon tipped adjusting screw to the overlever from the open G vent to finely regulate its closure with the LH thumbplate.
