Conn-Selmer 3512 MOUTHPIECE
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.
