What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 01
Designed around A440 tuning used in the US. A442 versions play sharper and are meant for European pitch standards.
Detail 02
A close tip opening with a long facing curve. More resistance, more control, less volume ceiling than open-tip pieces.
Detail 03
Fits Bb soprano clarinet only. Eb, A and bass clarinet mouthpieces are different sizes.
Detail 04
Pairs best with harder reeds. A soft reed on a close facing tends to feel stuffy and choke off.
Detail 05
Consistent chamber and bore dimensions between units, so a replacement plays close to the one you had.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
It is the pitch standard the mouthpiece is designed around — the tuning used by US ensembles. A442 versions sit slightly sharper for European groups.
The close tip opening generally calls for a harder reed than an open facing. Start firmer than your current strength and adjust from feel.
No. Plan on a ligature and cap separately, plus reeds. The mouthpiece alone will not get you playing.
No. This is a Bb soprano clarinet mouthpiece. Bass, Eb and A clarinets take different mouthpieces.
