All standard Bach mouthpieces are made with medium-sized throats which produce an even register, good intonation, and sufficient endurance for strenuous, all-around work. A small throat does not produce an easier high register; on the contrary, it not only chokes the tone but contracts the entire register, making high tones flat or the low tones sharp. A mouthpiece with an excessively large throat will make playing softly difficult, however, a large throat may help to produce a bigger tone.

Numbers and letters are drill bit sizes. The smaller the number, the larger the throat. Generally, the larger the throat, the freer blowing the mouthpiece and the more volume possible. However, as the throat size increases, the upper register tends to sharpen and the player tends to tire more quickly.
