About Yamaha Mouthpieces:

Quality brass mouthpieces contribute to the high regard Yamaha has earned among beginning and professional musicians alike.  As a result of their special approach to design and production, Yamaha mouthpieces deliver exceptional performance and comfort.

Yamaha’s manufacturing technique promises the highest level of consistent quality.  While other companies use a specific cutting tool to create every mouthpiece, (which causes problems as tools start to wear) Yamaha uses a computer-aided design system; which eliminates any possibility of a manufacturing flaw.  Yamaha’s computer controlled lathe work simply produces the most precise, consistent mouthpieces in the world.
