Best Clarinet Barrel: Backun, Buffet and More Compared

The best clarinet barrel upgrade is one of the most cost-effective improvements you can make to your instrument. Most players spend their entire career on the barrel that came in the box — which is a shame, because the best clarinet barrel changes how the instrument sounds and responds more noticeably than most other accessories at any price.

What the Best Clarinet Barrel Actually Does

The barrel connects the mouthpiece to the upper joint. It looks like a simple tube but its bore diameter, taper, length, and material all affect the sound and feel of the instrument in meaningful ways.

Length controls tuning. A longer barrel lowers overall pitch slightly; a shorter one raises it. Most Bb clarinets come with a 65 or 66mm barrel. If you consistently play sharp, a longer barrel helps. If you play flat, go shorter.

Bore shape and taper affect tone and response. The best clarinet barrel upgrades use a different bore profile than the stock barrel, which changes how the instrument responds and whether the tone is focused and dark or bright and open.

Material matters significantly. Grenadilla wood produces a warmer, more complex tone than the plastic or hard rubber stock barrels that come with most instruments. This is the main reason upgrading makes such an audible difference.

1. Backun MoBa — Best Clarinet Barrel Overall

The MoBa is the most widely used aftermarket clarinet barrel in the world. It produces a dense, focused, dark sound that projects well in large acoustic spaces — exactly what orchestral playing demands. The resistance is slightly higher than many barrels, which rewards developed air support and gives a sense of control that stock barrels simply don’t provide.

Available in grenadilla and cocobolo wood, both of which play similarly — the choice is mostly visual. It fits Buffet, Yamaha, Leblanc, and most other standard Bb clarinets. For Selmer Paris instruments you need to specify Selmer fit when ordering.

The MoBa comes in multiple lengths. Measure your current barrel or check with a teacher before ordering to make sure you get the right one.

2. Backun Lumiere — Best Clarinet Barrel for Solo Playing

The Lumiere is the best clarinet barrel for players who want warmth and clarity over projection. It lightens a naturally dark clarinet sound, adds sweet overtones, and produces a tone that works beautifully in chamber music and solo recitals where the audience is close and subtlety matters more than power.

Players who find the MoBa slightly too dark or resistant often gravitate to the Lumiere. At a higher price it’s aimed at advanced players who have found their sound and want a specific refinement of it.

3. Buffet Chadash — Best Clarinet Barrel for Buffet Players on a Budget

If you play a Buffet clarinet and want a meaningful upgrade without Backun pricing, the Chadash barrel is the most natural starting point. Made by Buffet specifically for their instruments, it uses a bore profile that produces a warmer, more centered tone than the stock barrel. Most Buffet players find it a clear and immediate improvement.

Available in 65mm and 66mm — the shorter 65mm suits players who run sharp, the 66mm suits those at standard pitch.

4. Buffet Moennig — Best Clarinet Barrel for Projection

The Moennig has been a favourite among professional Buffet players for decades. It produces a full-bodied, projecting tone with excellent response throughout the range. Many players describe it as making the clarinet feel more alive — more immediate and precise in response to subtle changes in air and embouchure. Available in 65mm and 66mm for Buffet instruments.

How to Choose the Right Barrel Length

Before ordering the best clarinet barrel for your setup, spend a session with a tuner and check where you naturally sit in pitch. If you consistently play sharp — especially in the upper register — a longer barrel (66 or 67mm) helps. If you play flat, go shorter.

The tonal upgrade comes from the wood and bore design, not from length. Use length to solve an intonation problem. If you’re not sure, ask your teacher before ordering — getting the wrong length is an expensive mistake.

For players upgrading their full setup, pairing a new barrel with a quality mouthpiece makes a significant difference. See our guide to the best clarinet mouthpieces for what works best at each level.

FAQ

Is a clarinet barrel upgrade worth it for students?

Not until the student has been playing consistently for at least two to three years with a stable embouchure and air support. The tonal differences the best clarinet barrel provides require developed technique to realize. Earlier in the journey, quality reeds and a mouthpiece upgrade will make more difference.

Will a Backun barrel fit my Yamaha clarinet?

Yes — Backun’s Standard fit works with Buffet, Yamaha, Leblanc, and most other major brands. Selmer Paris is the exception and requires Selmer-specific fit. Always check the product listing before ordering.

Does the best clarinet barrel change the pitch?

Yes — barrel length directly affects overall tuning. A longer barrel lowers pitch; a shorter one raises it. Order the same length as your current barrel unless you have a specific intonation problem you’re trying to solve.
