When selecting a mouthpiece, a brass instrumentalist should choose one with a solid, compact tone of large volume. A carefully selected Bach mouthpiece can help improve a player’s embouchure, attack, tonguing and endurance.
Because no two players have the same lip or tooth formation, what is perfect for one may be entirely unsuitable for the other. Bach produces many different models so that each player can find the best mouthpiece for their individual embouchure.
A mouthpiece consists of the rim, cup, throat, and backbore. Bringing these various components into proper relationship constitutes the art of superior mouthpiece production.
In choosing a special combination of rim, cup, throat and backbore designs, consider the effects of each.
Wide: Increases endurance
Narrow: Improves flexibility, range
Round: Improves comfort
Sharp: Increases brilliance, precision of attack
Large: Increases volume, control
Small: Relieves fatigue, weakness
Deep: Darkens tone, especially in low register
Shallow: Brightens tone, improves response, especially in high register
Large: Increases blowing freedom, volume, tone; sharpens high register (largest sizes also sharpen low register
Small: Increases resistance, endurance, brilliance; flattens high register
Except in general terms, it isn’t possible to identify backbores by size because they also vary in shape. Various combinations of size and shape make the tone darker or more brilliant, raise or lower the pitch in one or more registers, increase or decrease volume. In each instance, the effect depends in part on the throat and cup used in combination with the backbore.
