Though it’s a fact little known outside professional circles, Yamaha has been producing special custom-made mouthpieces for hundreds of the world’s top players at their R&D Ateliers for many years. These artists were not satisfied with any commercial models available. The players knew from the experience gained in their long careers exactly the kind of sound and response they wanted, and Yamaha's technicians knew from their long experience in crafting instruments how to deliver it.
More and more colleagues and students of these top players began to ask Yamaha for copies of the mouthpieces, so they decided to offer a select lineup of them in a new Signature Series. Now others can share in the results of this great cooperative effort between artist and artisan.
The Jazz model has a fairly deep roomy cup for a warm, big sound, and a throat and backbore designed to give enough "jump and snap" for manoeuvring through quick jazz passages with a rich full sound.
