Backbore<br />
The “backbore” is the inner<br />
section of the mouthpiece bore which<br />
follows the throat. The backbore has<br />
a complex flare which can significantly<br />
affect high-register pitch. The<br />
diameter of the backbore also influences<br />
timbre and resistance. Like<br />
most other diameter-related parameters,<br />
a narrow backbore results in<br />
increased resistance, brighter tone,<br />
and easier playing in the high register.<br />
A larger backbore decreases<br />
resistance for darker tone and easier<br />
playing in the lower range.<br />
Shank<br />
This parameter is of prime importance<br />
in determining how well a<br />
mouthpiece matches your instrument.<br />
The taper of the mouthpiece shank<br />
must perfectly match the instrument’s<br />
receiver — there should be<br />
absolutely no “play”. The outer<br />
diameter of the shank determines<br />
how deeply the mouthpiece seats in<br />
the receiver, thus affecting overall<br />
pitch, the accuracy of individual<br />
notes, and even playing feel.<br />
