  • 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.

Vocalise G Mouthpiece

How sweet it is!!!! This mouthpiece sounds so beautiful, it improved my intonation and my articulation sounds clean and crisp. The notes come out so easily now. I could not be happier. Thank you Backun!

I bought the H model and it played just as expected. It's much louder but it doesn't give me a bad sound and you can barely hear me bridging octaves with this on. Absolutely perfect.

Really Shines in the Altissimo Register

The G model really impressed me with the tuning and how easy the articulation works. For me where the mouthpiece really shines in the upper and altissimo register. The notes have hold and there is no spread, really beautiful. My strength of reeds have been 3 and sometimes 3.5 with the V12 and blue box. No issues at all with reeds for me. I may be picking up another one for a backup in the near future.

Not convinced

I bought a Vocalise G because I've heard that it should work well with synthetic reeds. (I'm a doubler, so I play Legere on most reed instruments, but I have stuck with Vandoren reeds on the clarinet when I need to sound great.) Sadly, my expectations have not been met. Compared to my Vandoren B40 MP, my tone is both weaker and brighter, both of which is the opposite of what I want. My ideal sound would be dark and full, and slightly wooden/reedy. I will give it a bit more time, and see if things improve when I get more used to it (it's been a few weeks, but I've spent most of my practising time on other instruments), and I'll try a harder reed too.

Thank you for your review. We think that you'd be more happy with the H model given that you prefer the B40. We look forward to your response to our email regarding this and we do hope you'll find you the perfect five star mouthpiece! - Team Backun

Amazing product!

The Mouth piece plays beautifully! A huge step up from the Debut Student mouth piece I was previously using. I am able to move more freely between the registers with this mouth piece, and am able to produce a richer more beautiful tone.

Vocalise G for Bb Clarinet

I am very happy with the Vocalise G. It gives me a better dynamic range than I had on the R model, I am more in tune, and it just fits comfortably in my mouth. I’m using the G all the time now with the Legere European cut 3.5 reed. Thank you!
