The Throat
All standard Bach mouthpieces are made
with medium-sized throats which pro-
duce 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.

NOTE: 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.
