Essential Mouthpiece Parameters
Every player needs to find the size and style of mouthpiece which best suits both his or
her physical and musical requirements. Since different mouthpieces can emphasize different
embouchure muscles, it is difficult to pinpoint the ideal mouthpiece at a single testing. A little
knowledge can, however, provide a valuable foundation for making the right choice.

Dimensions & Shape
The dimensions and shape of a mouthpiece have a direct effect on its feel, playability, and sound. Use
the parameters described below as a general guide when shopping around.
Inner Rim Diameter (Internal)
In general, a small rim diameter makes it easier
to play high notes and can increase endurance,
but volume is limited. A larger rim diameter, on
the other hand, provides plenty of volume and
easy low tones but endurance may be sacrificed.
The ideal rim diameter will depend on each
player’s physical traits, playing style, and musical
requirements. The factors involved are very
individual … some players spend years searching
for the perfect rim.
Rim Contour
Since this is the part of the mouthpiece that
comes into direct contact with the player’s lips,
it is a critical parameter for playing comfort. Rim
contour also has a large effect on attack clarity. A
majority of players prefer a relatively flat contour
with the peak closer to the inner edge. This type
of contour is generally considered to be the
most stable, providing optimum contact with
the rim bite (described on the next page). Avoid
mouthpieces with scratched or pitted contours.
