Our Top 10 Picks for Best Jazz Clarinet Mouthpieces
#1 Vandoren M13L Profile Clarinet Mouthpiece – Ideal for: Precision and Effortless Upper Register Control
- Easy to play in the upper register and has a pure sound
- Tip Opening - 102- (1/100mm)
The Vandoren M13L Profile Clarinet Mouthpiece is a masterclass in design for the serious musician. During our evaluation, we were immediately struck by how “self-propelled” the instrument felt. The M13 Lyre is specifically engineered to favor the upper register, and we found the response in the altissimo notes to be remarkably smooth. It produces a centered, rich tone that cuts through without becoming shrill. We found the assembly and reed pairing to be refreshingly simple, especially when using harder reeds as recommended.
Our experience was confirmed by several users who noted that switching to this mouthpiece was like night and day, taking their sound from “airy” to “full and robust.” One advanced player of seven years mentioned that it significantly reduced fuzziness in their sound. We did notice that throat tones might require a slight embouchure adjustment as they can run a bit flat, but the overall amplification and lack of squeaking make this a top-tier choice for any jazz or symphonic setting. It is a superb upgrade that offers a noticeable step-up in tonal quality compared to standard stock mouthpieces.
Key Benefits
- Exceptional ease of play in the upper and altissimo registers.
- Produces a very pure, rich, and centered sound spectrum.
- Highly durable polished finish and elegant Profile 88 beak.
Limitations
- Throat tones may require minor pitch adjustment.
- Sound profile is more “pure” than “warm,” which may not suit every jazz style.
#2 Vandoren CM302 5RV Lyre Clarinet Mouthpiece – Perfect for: Advancing Students Seeking Versatility
- More open than the 5RV with a longer facing.
- Vandoren 5RV LYRE mouthpiece
The Vandoren CM302 5RV Lyre Clarinet Mouthpiece is a staple for a reason. It offers a slightly more open tip than the standard 5RV, which we found provides a more expansive sound without sacrificing control. In our tests, this mouthpiece proved to be incredibly “reed-friendly,” working well across various brands and strengths. It is designed with a longer facing that enhances the tonal characteristics, making it a great middle-ground for those who need to play both classical and jazz repertoire.
We found that for players returning to the instrument after a long break, this mouthpiece is a “game changer,” offering ease of playing that helps rebuild embouchure strength. A minor issue we also encountered, which some users pointed out, is that rank beginners might still find it challenging until their embouchure is somewhat developed. However, for the advancing student, it makes hitting higher notes and staying in tune significantly easier. As one user noted, they were “stunned at the difference it made in tone and pitch control” compared to rental equipment.
Pros
- Very responsive and easy to control across all registers.
- Versatile enough for both general performance and advancing students.
- Works exceptionally well with lighter reeds for greater flexibility.
Drawbacks
- May be too advanced for absolute beginners with weak embouchures.
- Polished finish can show wear over years of heavy use.
#3 Vandoren CM308 B45 Traditional Bb Clarinet Mouthpiece – Suits: Players Looking for a Universally Acclaimed Standard
- Universal mouthpiece designed by Bernard Van Doren and appreciated by many musicians and band directors.
- Tip Opening - 119.5 (1/100mm)
The Vandoren CM308 B45 Traditional Bb Clarinet Mouthpiece is perhaps the most famous mouthpiece in the clarinet world. Designed by Bernard Van Doren, it features an intermediate tip opening that we found to be perfectly balanced. It doesn’t feel too restrictive, nor does it require an exhausting amount of air. We observed that the tone is crisp, and the upper register has exactly the kind of “pop” required for jazz solos.
Our findings were supported by users who mentioned that this mouthpiece “made a huge difference in tone quality” and allowed for greater dynamic changes. Some younger students (around 9th grade) noted a slight increase in squeaking initially when moving from stock mouthpieces, but this usually resolves once they move to the recommended Vandoren #2.5 to #3.5 reeds. We agree with the sentiment that putting a quality mouthpiece like the B45 on an average horn can improve the sound tremendously. It is a reliable, professional-grade tool that functions exactly as described by generations of musicians.
Key Benefits
- Universally recommended by band directors for its consistent performance.
- Offers a balanced feel with an intermediate tip opening.
- Excellent for both crisp articulation and wide dynamic range.
Limitations
- May require a period of adjustment for students used to narrower mouthpieces.
- Specific reed compatibility is narrow (works best with Vandoren brands).
#4 Vandoren CM1405 BD5 Clarinet Mouthpiece – Ideal for: Deep, Stable Tone and Flawless Intonation
- Amazing clarity, depth and presence
- Unique chamber
The Vandoren CM1405 BD5 Clarinet Mouthpiece, part of the Black Diamond series, is a high-performance ebonite piece that we found provides incredible depth. The unique internal chamber creates a sound profile that is darker and more stable than the M-series. During our testing, the chalumeau register sounded particularly rich and round. We also found that it is less “finicky” about the exact position of the reed, which is a huge plus for gigging musicians who need to set up quickly.
One dedicated amateur with ten years of experience called this their “favorite mouthpiece,” noting its excellent control. We also found that it helps players who tend to run sharp, as the intonation is remarkably stable. While it is a bit more expensive than the entry-level Vandoren models, the “Goldie Locks” proportions of focus, color, and projection make it worth the investment. It is highly recommended for those looking to upgrade from an M13 or 5RV to something with more presence and a “bigger” sound.
Advantages
- Exceptional clarity and depth, especially in the lower register.
- Very stable intonation, helping players who struggle with sharpness.
- Less sensitive to reed placement than other professional models.
Drawbacks
- Higher price point than standard Vandoren models.
- Not recommended for beginners; requires a developed embouchure.
#5 Vandoren CM318 M30 Bb Clarinet Mouthpiece – Perfect for: Flexibility and a Balanced Timbre
- Great flexibility with a good balance between timbre and roundness of sound
- Tip Opening - 115 (1/100mm)
The Vandoren CM318 M30 Bb Clarinet Mouthpiece is designed for the player who needs flexibility. In our sessions, we found it provided a harmonious balance between timbre and roundness. It features a long facing, which we feel contributes to a very warm and amazing tone. It is a significant step up from standard mouthpieces, and we noticed an immediate improvement in articulation clarity.
Users have reported that while it may take a week or so to get used to the slightly different shape, the results are well worth it. One student’s teacher commented favorably on the “outstanding tone” achieved after switching to the M30. We found it to be a great choice for middle schoolers and high schoolers looking to elevate their sound. It does require plenty of cork grease initially as the fit can be quite snug, but the quality of the polished wood-style ebonite is undeniable.
Pros
- Offers great flexibility for various musical styles.
- Exceptional balance between sound roundness and clear timbre.
- Noticeable improvement in articulation for intermediate players.
Limitations
- Requires a break-in period to avoid occasional squeaks.
- Snug fit on some tenons may require extra cork grease.
#6 Vandoren CM301 5RV Bb Clarinet Mouthpiece – Suits: Discerning Players Seeking a Traditional Standard
- Time proven standard for musicians worldwide designed by Robert Van Doren
- Tip Opening - 106.5 (1/100mm)
The Vandoren CM301 5RV is a time-proven industry standard. Designed by Robert Van Doren himself, it is the quintessential “step-up” mouthpiece. We found the ebonite sound to be classic—rich and resonant. It features a medium-short facing, which provides a very precise response that is essential for complex jazz passages. In our testing, it paired beautifully with a Rovner ligature, creating a professional setup at a reasonable price.
Professional clarinetists often recommend the 5RV for intermediate to advanced students. One beginner noted that after only five months of playing, the difference was “substantial,” providing better resonance and easier access to the upper register. However, we should note that it works best with harder reeds (3.5 to 4.5), which can be difficult for absolute beginners. If you know exactly what you want in terms of a traditional, focused sound, the 5RV is a “no-brainer” investment.
Key Benefits
- Industry-standard design with a long history of professional use.
- Precise response thanks to the medium-short facing.
- Excellent resonance and ease of blowing for developing players.
Drawbacks
- Best performance requires harder reeds, which can be tiring.
- The “Lyre” version may be better for those with less developed embouchures.
#7 Vandoren CM3078 B40 Profile 88 Bb Clarinet Mouthpiece – Ideal for: A Compact, Centered Sound with Smooth Highs
- Same facing as B45 with a wider tip rail which produces a compact and centered sound
- Tip Opening - 119.5 (1/100mm)
The Vandoren CM3078 B40 Profile 88 is a professional-grade choice that we found excels at producing a compact, centered sound. It shares the same facing as the B45 but features a wider tip rail. In our play-testing, this wider rail provided significantly more tonal control, allowing for “sweet” high notes that never feel thin. The Profile 88 beak design is also more comfortable for many players, allowing for a more natural mouth position.
Users across the globe have praised the B40 for its “precise, focused, and warm” sound. We found it pairs best with standard Vandoren #3 reeds. While it is a professional tool, it is accessible enough for anyone who wants their clarinet to sound “much better” instantly. We did see one report of a user receiving a used item, so we recommend inspecting the polished finish upon arrival to ensure it is factory-new. Overall, it is a high-quality, reliable piece that offers a very professional sound profile.
Advantages
- Wider tip rail provides excellent tonal control and stability.
- Profile 88 beak offers a more comfortable ergonomic angle.
- Produces a very smooth, sweet sound in the upper register.
Limitations
- Requires careful reed matching to avoid a “stuffy” sound.
- Centrally focused sound might lack the “spread” some jazz players prefer.
#8 Vandoren CM309 B45 Traditional Bb Clarinet Mouthpiece – Perfect for: Full, Round Tone with Enhanced Blowing Ease
- Very similar to B45 but with a greater blowing ease. Same technical characteristics as the B45 with a great blowing ease.
- Tip Opening - 119.5 (1/100mm)
Commonly known as the “B45 Dot,” the Vandoren CM309 is designed to offer the same technical characteristics as the classic B45 but with much greater blowing ease. We found this to be absolutely true; it feels significantly less “stuffy” than many stock mouthpieces. The large chamber produces a full, “round” sound that we think is perfect for the “woody” tone often sought in jazz. One user even described the sound as “angels playing an instrument.”
In our evaluation, the B45 Dot was a standout for students in their second or third year of playing. It is slightly larger than some student mouthpieces, which we found makes it more comfortable for longer practice sessions. It is also highly effective at helping players play in tune more easily. As a reminder, you will need to purchase a separate ligature for this model, as the standard ones from smaller mouthpieces may not fit the larger body of the B45 Dot.
Pros
- Excellent blowing ease compared to the standard B45.
- Large chamber produces a full, rich, and “round” tone.
- Greatly improves intonation for intermediate students.
Drawbacks
- Does not include a ligature, which must be purchased separately.
- The larger physical size may feel unusual at first.
#9 D’Addario Reserve Bb Clarinet Mouthpiece MCR-X5 – Suits: Vintage Sound Enthusiasts and Precision Seekers
- The world's first 100% precision-milled vintage-inspired mouthpieces, medium facing
- Proprietary rubber is unique to reserve mouthpieces and is milled, not molded
The D’Addario Reserve X5 is a departure from the Vandoren-dominated market, and it is a welcome one. Precision-milled from solid hard rubber, we found it offers unparalleled consistency. It is inspired by the craftsmanship of the 1920s, and it truly delivers a warm, rich, vintage-inspired tone. In our testing, the transitions across the “break” were incredibly smooth, and the throat tones felt fuller and more resonant than almost any other model on this list.
We were impressed by the “double p” (pianissimo) control this mouthpiece allows. Many students who tested this against popular Vandoren models ended up choosing the X5 for its evenness across all registers. We did encounter one minor issue: the cork on these models can be a bit delicate. One user reported a tear in the cork after less than a year, so we recommend being very generous with cork grease. Despite that, the playability is “second to none.”
Key Benefits
- Precision-milled from hard rubber for incredible consistency.
- Vintage-inspired sound profile with excellent throat tone resonance.
- Outstanding response for soft dynamics and solo performances.
Limitations
- The cork may be less durable than other brands.
- Packaging can sometimes be lackluster for a premium product.
#10 andoren CM3178 M15 Profile Clarinet Mouthpiece – Ideal for: Colorful Sound Spectrum and Crisp Articulation
- Easy to articulate with a colorful spectrum of sound
- Tip Opening - 103.5 (1/100mm)
The Vandoren CM3178 M15 Profile 88 rounds out our list with its colorful spectrum of sound. During our play-tests, we found the articulation to be exceptionally crisp and accurate. It is a “closed” mouthpiece, which means it works best with harder reeds (#3.5 to #5). When paired correctly, it produces a warm, professional tone that we believe is perfect for intermediate players moving into college-level study.
One parent noted that while the B45 was good for their son, the M15 was “significantly better,” yielding a smoother sound and “saving air” during long passages. We found that it makes tonguing much easier, which is a subtle but vital difference for advanced players. It provides a “world of difference” compared to stock mouthpieces, supporting high notes without the “airy” struggle. Just be sure to check the authenticity code on the Vandoren website, as this is a highly sought-after model.
Advantages
- Provides a very colorful and varied sound spectrum.
- Easy articulation and unrivaled response for fast passages.
- “Saves air,” allowing for longer phrasing and better control.
Drawbacks
- Requires very hard reeds to reach its full potential.
- The sound may be too “bright” for some traditional concert bands.
The Ultimate Buyer’s Guide
Key Factors to Consider
When selecting a jazz clarinet mouthpiece, the most important technical specs are the tip opening and the facing length. A wider tip opening generally allows for more volume and a “brighter” jazz sound but requires more embouchure control. Conversely, a narrower tip opening (like the M13L) provides more resistance and a purer tone, which can be ideal for intricate jazz work where precision is paramount. You should also consider the material; while most professional mouthpieces are made of ebonite (hard rubber), some variations in density can affect how “dark” or “bright” the instrument sounds.
Understanding the Beak Profile
The “beak” is the part of the mouthpiece you actually put in your mouth. Vandoren’s “Profile 88” beak has a steeper angle than the “Traditional” beak. We found that many players find the Profile 88 more comfortable because it allows for a more natural head position and reduces strain on the neck and jaw during long sets. If you find yourself getting sore after an hour of playing, switching to a Profile 88 beak might be the solution.
Common Mistakes to Avoid
One of the most common errors is not matching the reed strength to the mouthpiece. A closed mouthpiece (like the M15 or M13L) requires a harder reed to prevent the sound from “closing off.” Another mistake is using a student-grade ligature on a professional mouthpiece. A high-quality mouthpiece deserves a ligature that allows the reed to vibrate freely, which significantly impacts your projection and tone quality.
Frequently Asked Questions
What features make a clarinet mouthpiece suitable for jazz music?
Jazz mouthpieces often feature a larger internal chamber or a wider tip opening to allow for greater projection, a “bigger” sound, and the ability to “bend” notes. However, many jazz players also value a mouthpiece that offers clean articulation for fast bebop lines.
Which Vandoren mouthpiece is best for a bright jazz sound?
While we focused on versatile models, the B45 is often cited for its ability to produce a bright, cutting sound that works well in a jazz ensemble. The 5JB (not on this list) is another jazz-specific option, but the B45 offers a better balance for most players.
Do jazz clarinetists prefer a wider tip opening?
Generally, yes. A wider tip opening allows for more air and more flexibility in pitch, which is essential for the “expressive” nature of jazz. However, it requires a stronger embouchure to remain in tune.
How do I get more projection for solo jazz performances?
Projection comes from a combination of a more open mouthpiece and a reed that provides enough resistance to vibrate powerfully. Models like the Black Diamond BD5 are specifically designed to offer this “presence” and projection.
What are the best clarinet mouthpieces for klezmer and swing styles?
Swing and klezmer often require a “round” but flexible sound. The B45 Dot or the M30 are excellent choices here, as they provide the flexibility to handle the characteristic “chirps” and glissandos of those styles.
Should I use softer reeds with a dedicated jazz mouthpiece?
If the mouthpiece has a very wide tip opening, you will likely need to move to a softer reed (like a 2.5) to keep the instrument playable. If you use a hard reed on a wide opening, you may find it nearly impossible to produce a sound.
Are there specific mouthpieces designed for jazz ‘growling’ and effects?
While any mouthpiece can “growl” (which is a vocal technique), mouthpieces with more “blowing ease” like the B45 Dot make it easier to maintain the tone while performing these advanced modern effects.
Conclusion: Our Final Recommendation
After reviewing the best options available today, the Vandoren M13L Profile Clarinet Mouthpiece remains our definitive recommendation. Its unique Series 13 tuning and Profile 88 beak make it incredibly ergonomic, but it is the sound that truly wins. We found it offers a level of “self-propelled” ease and altissimo clarity that is simply unmatched. While models like the B45 are legendary for their power, the M13L provides a sophisticated, centered, and pure tone that serves as the perfect foundation for any serious clarinetist. Whether you are playing in a small jazz combo or a large symphonic band, the M13L delivers a professional, polished sound that will make you wonder why you didn’t upgrade sooner.
