Different mouthpieces can emphasize different embouchure muscles. The dimensions and shape of a mouthpiece have a direct effect on its feel, playability and sound.
INNER RIM DIAMETER
In general, a small inner rim makes it easier to play high notes and can increase endurance but volume is limited while a larger inner rim diameter 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.
RIM THICKNESS
Although a thick rim provides greater lip contact area for easy high notes and extended endurance, lip movement is limited so you lose tonal flexibility. A rim that is too thin offers plenty of control over a wide range but can quickly cause fatigue. Beginner players are probably better off choosing a rim of medium thickness. The best approach is to play a variety of types and choose the one that feels the most natural and plays the easiest.
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. 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 optimium contact with the rim bite.
RIM BITE
The bite of the rim has a large influence on attack clarity and pitch control. Mouthpieces with a sharp bite generally make it easier to produce accurate, stable pitch and a rich tone. If the bite is too sharp, the lip control is limited and it becomes difficult to make smooth note to note transitions. A sharp bite can also be painful on the lips and reduce endurance. At the other extreme, a round, very soft bite may be comfortable to play but will produce a blurred attack and poorly defined pitch.
CUP SILHOUETTE
Cup silhouette encompasses both cup depth and shape. Shallow cups produce a brighter tone and are more controllable in the higher register at the expense of volume. Deep cups offer a dark tone, easy low notes and plenty of power. Cup shapes range from "U" shapes to "V" shapes. The more "U" shaped a cup is, the brighter the sound and the easier it is to play in the high register. As a cup approaches the "V" shape, the sound becomes darker and the lower register becomes easier to play.
THROAT DIAMETER
The throat is the narrowest portion of the mouthpiece bore and therefore the point of the highest sound pressure. The diameter and length of this part of the mouthpiece have a major influence on playing resistance. A narrow, long throat produces high resistance which contributes to fast response, brillant tone and enhanced playability in the high register. A wide, short throat is more playable in the low register and is capable of producing greater volume but requires lots of air from the player and can lead to fatigue.
BACKBORE
The backbore is the inner section of the mouthpiece bore which follows the throat. The backbore has a complex flare which can significantly affect high register pitch. A narrow backbore results in increased resistance, brighter tone, and easier playing in the high register. A larger backbone decreases resistance for darker tone and easier playing in the lower range.
