>At the recommendation of Morie Bakun, I shortened one f my mouthpieces by 1mm and had a pin installed in the cork pad
of the register key. This was a Buffet RC C clarinet. The clarion and above were flat. The chalumeau A and B were a bit
sharp on the Buffet also. Pulling the upper and lower joints apart slightly lowered the chalumeau. After all the adjusting my
lower lip still got sore pinching up the clarion register.
