Shattering expectations with precision and flexibility.


A custom mouthpiece for Corrado Giuffredi, the Maestro himself, the Vocalise CG was designed by renowned craftsman, Richard Hawkins to replicate the playing characteristics of crystal in a mouthpiece that is machined to unbelievably high tolerances.

Crafted from a proprietary clear synthetic material, the Vocalise CG Mouthpiece is Open/Long, while giving players a flexible and vibrant tone. Vocalise CG Mouthpieces are manufactured using the most technologically advanced nine-axis machining available today. For those looking for a mouthpiece that articulates with ease and holds a clear quality of sound at extreme volumes, this model delivers on stage and in the studio.

Like all Vocalise Mouthpieces, the CG model is exceptionally versatile and adaptable to a wide range of playing styles, and is suitable for both synthetic and cane reeds, alike.

In the words of the Maestro: YES!

Richard Hawkins on the Vocalise CG

“The Vocalise CG Bb Clarinet Mouthpiece is the first of its kind. A clear material that embodies the compactness of sound that glass/crystal creates, while benefitting from the exceptional consistency that advanced machining offers. It is a material not molded, but rather, milled like hard rubber to extremely precise tolerances. This model has a voice that combines darkness and lightness to the sound with remarkable volume and heftiness. Extreme louds hold the quality of sound unlike any other mouthpiece or material I’ve ever come across.”

Quick response, dark tone

The CG had a much quicker response than my M30 had, and the tone was still so dark!

The CG vocalice mouthpiece has greatly improved the tuning, as it was one of my problems for playing. In addition it has a greater projection in the sound, This makes me very happy with the response in the all register on my clarinet. The combination with a leather ligature create a dark sound, I love that. In summary, this mouthpiece is a master piece.
