  • Complex simplicity by Hawkins and Backun

    “It has long been my goal to create a clarinet mouthpiece that satisfies the nuances of change while preserving the history of the craft.” – Richard Hawkins

    Outstanding artist. Renowned educator. Master craftsman. Words and praise that are often bestowed upon Richard Hawkins. After decades of collecting, observing and crafting mouthpieces for many of the world’s finest artists, Hawkins collaborated with Backun Musical Services to develop a series of mouthpieces with tonal ring and clarity that will change the course of mouthpiece history.

    Designed for all ages and experience levels, the Vocalise Series of B♭ mouthpieces features a model for every player and occasion, all of which belong in your clarinet case. Complex resonance at a reasonable price.

Note: All New Mouthpieces from Backun are cleaned, disinfected and sterilized for your health and safety. 

Washing Instructions: We recommend you wash your mouthpieces with warm water and mild dishwashing soap and then air dry it on a clean cloth. In classroom and group situations, we recommend the use of the Red Sterisol cleaner for its proven capability to clean, deodorize and sanitize mouthpieces. 

Please do not immerse your mouthpieces in, or clean your mouthpieces with, isopropyl, or other members of the hydroxyl group of products. 

Vocalise Models





The R allows artists to articulate with reduced effort, while ringing true with fabulous clarity.




The G has a smoother influence on interval connections just when you need it.




The H is both smooth and dark, with ample cushion for those who want more flexibility.



Extremely Open/Long

Designed for artists who prefer a larger facing, while offering significant volume and projection.


Richard Hawkins on the New Vocalise Z

One gets excited about the development of something new and unusually rare in the history of clarinet mouthpieces. Together with the team at Backun, we developed the Vocalise Z model to give players not only polished flexibility, but volume and pop to the core sound. It is louder, bigger and has the dexterity to shine in any type of music. It is a mouthpiece like no other in its ability, out-of-the-box, to be louder in tone without the typical harshness, yet it does not require more embouchure pressure to perform. Addicting to play and hard to put down, this model has exceeded my expectations.

Grand slam of mouthpieces

Simply put watch the video above. For almost forty years I always played on very closed set-ups so I naturally tried the R first which I loved. Then being curious I tried the G which played even smoother. Recently I picked up the H and Z. Incredible! All four mouthpieces are great and can be played with a variety of different reed strengths. I played Silverstein Ambipoly P and V ranging from 3.5 + to 4.5

After playing a myriad of mouthpieces over the last several years, finally a mouthpiece that provides the ease, color, intonation and response I've been looking for. The combination of the Buffet Prestige, ICON barrel and the Vocalise G allow me to focus on musical expression without physical tension. Seriously considering the Vocalise H for greater projection in orchestra.

Great Mouthpiece

Works great with Legere Reeds.

Z is for Lazaro

The Z is extremely easy to play and in tune with the same non resistance up and down the scale. I would prefer to use it on my Alpha 1st and Moba 2nd. The Alpha more because of its projection. With a fatboy on the Alpha, it would be difficult to put this one down. It rivals my R13s. But, the Moba with a Lumiere barrel is really exciting. It's like driving a Ferrari with a bunch of Volvos, whatever. What is even better using a Silverstein ligature? However, how it sounds in an ensemble will have to wait until next year for my adult bands get started again. The Moba is easier to handle with the Tooiman brass plate for the Maestro, which replaces the original thumbrest. Weight seems to be well distributed over both arms. Five stars for the brass plate.

Vocalise H Mouthpiece

Purchased because mouthpiece said to work well with Legere synthetic reeds. Took a few days to get used to it, but it appears it does indeed work well in terms of control, tone, etc.

It was suggested that I try a Vocalise as that would really simplify things ... the first time I put it on, I was amazed at the ease of playing with higher reeds than I was used to.
