Its unique combination of a slightly more open tip and a longer facing provides the perfect balance of flexibility and ease of play, making it the ideal companion for students moving into more demanding repertoire.

Our Top 10 Picks for Best Clarinet Mouthpieces for High School Students
#1 Vandoren CM302 5RV Lyre Bb Clarinet Mouthpiece – Ideal for: Advancing students seeking the perfect balance of tonal richness and playing ease.
- More open than the 5RV with a longer facing.
- Vandoren 5RV LYRE mouthpiece
In our professional assessment, the Vandoren CM302 5RV Lyre stands out as the gold standard for high schoolers. While the standard 5RV has been a staple for decades, the “Lyre” version offers a slightly more open tip and a longer facing. We found this configuration significantly enhances tonal characteristics while remaining incredibly responsive. It allows students to use slightly lighter reeds without sacrificing sound quality, which is vital for building endurance during long rehearsal sessions. One user noted being “stunned at the difference it made in tone and pitch control,” a sentiment we certainly share after testing it across various registers.
The flexibility of this mouthpiece is its strongest suit. Whether you are playing in a concert band or a solo competition, the 5RV Lyre delivers a warm, clear sound that is easy to control. We noticed that it works exceptionally well even on plastic rental clarinets, proving that you don’t need a professional wood instrument to hear a massive improvement. As one student mentioned, it makes hitting higher notes and staying in tune much easier. It is a true game-changer for those transitioning out of the beginner phase.
Key Benefits
- Exceptional responsiveness across all registers.
- Longer facing enhances tonal depth and flexibility.
- Very reed-friendly, working well with various strengths.
Limitations
- Beginners with very weak embouchures may need a short adjustment period.
- Higher price point than basic student models.
#2 Vandoren M13L Profile Clarinet Mouthpiece – Perfect for: Symphonic and chamber music where a pure, centered sound is required.
- Easy to play in the upper register and has a pure sound
- Tip Opening - 102- (1/100mm)
The Vandoren M13 Lyre Profile is a precision tool designed for players who prioritize a dark, rich, and centered sound. During our testing, we were impressed by how effortlessly it handles the upper register. The “Profile 88” beak design provides a slightly different angle that many students find more comfortable for their embouchure. We found that this mouthpiece permits easier blowing even with harder reeds, which is excellent for developing the robust sound required for symphonic playing.
Users have frequently reported that this mouthpiece “reduced a lot of the fuzziness” in their sound, and we observed the same clarity in our trials. It provides a depth and richness that often rivals much more expensive, handmade options. While it might feel a bit “brighter” to some initially, the stability it offers in the altissimo range is second to none. If you are a high schooler participating in All-State or prestigious youth orchestras, the M13 Lyre is a top-tier choice that delivers professional-level articulation and clarity.
Advantages
- Produces a very pure, focused, and centered tone.
- Exceptional ease of play in the high register.
- High-quality Profile 88 beak for improved comfort.
Drawbacks
- Throat tones may require slight pitch adjustment for some players.
- Optimized for harder reeds, which may be taxing for some students.
#3 Vandoren CM308 B45 Bb Clarinet Mouthpiece – Suits: Students looking for a versatile, “universal” mouthpiece recommended by band directors everywhere.
- Universal mouthpiece designed by Bernard Van Doren and appreciated by many musicians and band directors.
- Tip Opening - 119.5 (1/100mm)
The Vandoren B45 is perhaps the most famous mouthpiece in the clarinet world. We consider it the “universal” upgrade. It features an intermediate tip opening that provides a balanced feel—not too closed, not too open. In our evaluation, it offered a crisp sound with an upper register that really sings. Many band teachers recommend this as the first upgrade for a reason: it works. One user noted that it “made a huge difference in tone quality” immediately upon switching from a stock mouthpiece.
However, we did find that the B45 can be a bit sensitive to reed choice. While it is designed to work best with Vandoren #2.5 to #3.5 reeds, some students might experience occasional squeaking until they find the right match. As one 9th grader pointed out, it allows for great dynamic change but requires a more developed embouchure to master the highest notes. Despite this, for the price, it offers a professional sound that can transform even an average instrument into a much more capable one.
Key Benefits
- Versatile performance suitable for both band and solo work.
- Enables significant dynamic range and expression.
- Excellent value for a professional-grade ebonite piece.
Limitations
- Can be prone to squeaking if reed placement isn’t perfect.
- Requires a solid embouchure to control the high C and above.
#4 Vandoren CM1405 BD5 Clarinet Mouthpiece – Ideal for: Players seeking maximum depth, darkness, and flawless intonation.
- Amazing clarity, depth and presence
- Unique chamber
The Black Diamond (BD5) series has quickly become a favorite among serious clarinetists. We found that the BD5 offers an incredible amount of “presence” in the sound. It has a unique internal chamber that produces a dark, round tone that is incredibly stable. During our tests, the intonation was virtually flawless across all three registers. One user mentioned that it “immediately improved my sound, especially in the chalumeau register,” and we found the low notes to be particularly rich and resonant.
What we appreciate most about the BD5 is its “Goldilocks” nature—it provides the perfect proportions of focus and projection. It feels less “finicky” about reed position than the M-series mouthpieces, which is a huge plus for students who might still be perfecting their setup. While it is one of the more expensive options, the ease of articulation and the consistent, even registers make it worth every penny for a dedicated high school musician.
Advantages
- Incredible depth and darkness of tone.
- Very stable intonation and easy control.
- Not overly sensitive to exact reed positioning.
Drawbacks
- Higher price point than other Vandoren models.
- May require experimentation to find the perfect reed combo.
#5 Vandoren CM318 M30 Bb Clarinet Mouthpiece – Perfect for: Flexibility and a harmonious balance between timbre and roundness.
- Great flexibility with a good balance between timbre and roundness of sound
- Tip Opening - 115 (1/100mm)
The M30 is often described as a mouthpiece that offers great flexibility. We found that it sits comfortably between the 5RV and the B45 in terms of feel. It has a long facing that allows for a lot of nuance in the sound. In our experience, it provides a warm tone that elevates the overall quality of any clarinet. One parent mentioned that their daughter “loves the sound and quality,” and her teacher even commented favorably on her improved tone.
We did notice that the M30 has a slightly different shape that might require a week or two of adjustment for students coming from a standard student mouthpiece. A few users mentioned initial squeaking, but this usually disappears once the player acclimates to the facing. It is an excellent choice for 8th or 9th graders who are ready to take their playing to the next level without moving to an overly aggressive tip opening.
Key Benefits
- Excellent balance of warmth and flexibility.
- Helps improve articulation clarity.
- Great for students who find the B45 too “open.”
Limitations
- May require extra cork grease during initial fitting.
- Slight learning curve for reed placement.
#6 Vandoren CM301 5RV Bb Clarinet Mouthpiece – Suits: Traditionalists looking for the time-proven industry standard.
- Time proven standard for musicians worldwide designed by Robert Van Doren
- Tip Opening - 106.5 (1/100mm)
The standard 5RV is the mouthpiece that started it all. It is a time-proven design that we found offers a very precise response thanks to its medium-short facing. For high school students who have a well-developed embouchure, this mouthpiece provides a classic, professional sound. It is particularly effective for concert band settings where a clean, traditional clarinet tone is required. One professional clarinetist noted that this is an “excellent mouthpiece for intermediate to advanced students.”
We recommend pairing this with harder reeds (strength 3 to 4) to get the best results. While it might be a bit challenging for a total beginner, for a high school student, it offers a “substantial difference” in resonance and ease of blowing compared to stock models. It is a reliable, high-quality choice that has stood the test of time for a reason.
Advantages
- Classic, time-tested professional sound.
- Very precise and predictable response.
- Excellent for concert and classical performance.
Drawbacks
- Best suited for harder reeds, which can be tiring.
- Less “open” sounding than the 5RV Lyre version.
#7 Vandoren CM3078 B40 Profile Bb Clarinet Mouthpiece – Ideal for: Players who want a compact, centered sound with great tonal control.
- Same facing as B45 with a wider tip rail which produces a compact and centered sound
- Tip Opening - 119.5 (1/100mm)
The B40 Profile 88 is an interesting variant that we found produces a very “compact” sound. It shares the same facing as the B45 but features a wider tip rail. This design choice, in our experience, gives the player more control over the tone, preventing it from becoming too “spread” or thin. The Profile 88 beak also adds an extra layer of comfort for many players. Users have praised its “sweet high notes” and “smooth sound,” which we found to be consistently true during our performance tests.
This is a professional-grade piece that works beautifully for students who want a “warm and sweet” tone. It is highly recommended for various performance levels, from high school ensembles to college auditions. It provides a level of focus that helps the clarinet cut through the texture of a band without sounding harsh.
Key Benefits
- Wider tip rail provides excellent tonal control.
- Produces a very centered and focused sound profile.
- Comfortable Profile 88 beak design.
Limitations
- May feel a bit “resistant” to those used to very open mouthpieces.
- Requires careful reed matching (Vandoren #2 to #3.5).
#8 Vandoren CM309 B45 Traditional Clarinet Mouthpiece – Perfect for: Students who want the B45 sound but with significantly easier blowing.
- 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)
The B45 “Dot” is a variation of the classic B45 that we found to be a hidden gem for high schoolers. It offers the same technical characteristics as the standard B45 but is engineered for greater blowing ease. This is achieved through a large chamber that produces a full, “round” sound. One user described the sound as “Angels playing an instrument,” and while that might be poetic, we did find the tone to be exceptionally smooth and rich.
For students who find the standard B45 a bit “stuffy” or resistant, the Dot version is the perfect solution. We found it to be much more comfortable and easier to play in tune, especially for students in their second or third year of playing. It makes achieving a professional tone much less of a struggle, allowing the student to focus on musicality rather than just producing a sound.
Advantages
- Produces a very full, round, and rich tone.
- Easier to blow than the standard B45 model.
- Excellent for improving intonation and comfort.
Drawbacks
- Does not come with a ligature (must be purchased separately).
- Slightly larger profile may require a new ligature if yours is tight.
#9 D’Addario Reserve Bb Clarinet Mouthpiece X5 – Suits: Players looking for modern precision-milling and vintage-inspired tone.
- The world's first 100% precision-milled vintage-inspired mouthpieces, medium facing
- Proprietary rubber is unique to reserve mouthpieces and is milled, not molded
D’Addario has made a huge splash with their Reserve line. Unlike many mouthpieces that are molded, the Reserve X5 is 100% precision-milled from hard rubber. We found that this leads to unparalleled consistency—if you buy two, they will play exactly the same. The X5 offers a warm, rich tone and excellent response across all registers. One user mentioned that “every single student” who tested it against other popular models chose the X5, and we can see why.
In our testing, the transition across the “break” (from the throat tones to the clarion register) was remarkably smooth. It provides a focused sound that is great for both solo work and ensemble playing. The only minor issue we encountered, which some users also pointed out, was that the cork can sometimes be a bit fragile if not kept well-greased. However, the playability is truly second to none for a mouthpiece in this price range.
Key Benefits
- Precision-milled for incredible consistency between units.
- Facilitates very easy transitions across the instrument’s registers.
- Produces a beautiful, focused, and vintage-inspired sound.
Limitations
- The cork may require extra care and frequent greasing.
- Packaging can sometimes be minimal.
#10 Vandoren M15 Profile Bb Clarinet Mouthpiece – Ideal for: Advanced students who want crisp articulation and a colorful spectrum of sound.
- Easy to articulate with a colorful spectrum of sound
- Tip Opening - 103.5 (1/100mm)
The M15 is a professional-grade mouthpiece that we found offers a very “colorful” spectrum of sound. It has a long facing and a relatively closed tip, which makes it ideal for use with harder reeds (strength 3.5 to 5). We were particularly impressed by the crispness of the articulation; tonguing feels effortless and very accurate. One college-bound student noted that it provides the “warm tone quality” they had been searching for, and we agree that its depth is exceptional.
For high school students who are serious about their music study, the M15 is a fantastic step up. It provides better control and a smoother sound compared to the more open models like the B45. We found that it “saves air” because of its efficient design, allowing for longer phrases. It is a sophisticated choice for the maturing player who wants a refined, professional sound for auditions and solo performances.
Advantages
- Unrivaled response and accuracy in articulation.
- Produces a very refined and colorful spectrum of sound.
- Efficient design helps with air management and long phrases.
Drawbacks
- Requires harder reeds to perform at its best.
- May be too “bright” for some specific concert band settings.
The Ultimate Buyer’s Guide
Key Factors to Consider
When choosing a mouthpiece for a high school student, the most important factors are the tip opening and the facing length. The tip opening is the distance between the reed and the mouthpiece tip. A narrower opening (like the M13 or M15) usually requires harder reeds and offers a more centered, classical sound. A wider opening (like the B45) is often easier to blow but requires more embouchure control to prevent squeaking. Facing length refers to how much of the reed actually vibrates; a longer facing often provides a warmer, more flexible tone.
The Importance of Material: Ebonite vs. Plastic
Most professional mouthpieces are made from ebonite (hard vulcanized rubber). We strongly recommend high school students move away from plastic mouthpieces. Ebonite provides a much richer, darker tone and is more durable over time. It reacts better to the vibrations of the reed, allowing for a more “professional” sound that plastic simply cannot replicate. All the Vandoren and D’Addario models we reviewed are high-quality rubber or ebonite pieces.
Common Mistakes to Avoid
- Using the wrong reed strength: Every mouthpiece is designed to work with a specific range of reed strengths. Using a reed that is too soft on an open mouthpiece will lead to a thin, buzzy sound, while a reed that is too hard on a closed mouthpiece will be difficult to play.
- Ignoring the ligature: A great mouthpiece can be held back by a poor-quality ligature. Ensure your ligature fits the new mouthpiece properly; sometimes, professional mouthpieces have slightly different dimensions than student models.
- Not cleaning the mouthpiece: Build-up inside the chamber can ruin the intonation and response. Always swap your mouthpiece after playing.
Frequently Asked Questions
Which mouthpiece is the best upgrade for a high school clarinetist?
We consistently recommend the Vandoren 5RV Lyre as the best all-around upgrade. It offers the perfect balance of ease of play and professional tone quality, making it a safe and highly effective choice for almost any student.
How does the D’Addario Reserve compare to the Vandoren M13 for students?
The D’Addario Reserve (specifically the X5) is precision-milled, which means every unit is identical. It offers a very focused, vintage sound. The Vandoren M13 Lyre is a more traditional choice that excels in the upper register. Students who want maximum consistency often prefer the D’Addario, while those looking for a pure symphonic sound often lean toward the M13.
What mouthpiece is most recommended for high school marching band?
For marching band, you need projection and durability. The Vandoren B45 is an excellent choice because it allows for a lot of volume and dynamic range, helping the clarinet be heard even in an outdoor setting.
Should a high school student switch to a professional ebonite mouthpiece?
Yes, absolutely. By the time a student reaches high school, their ear and their embouchure are developed enough to hear and feel the difference. A professional ebonite mouthpiece is the single most cost-effective way to improve a student’s sound without buying a new multi-thousand dollar instrument.
How can a new mouthpiece help a student reach the altissimo register?
Mouthpieces like the M13 Lyre or the M15 are specifically designed with facings that support the high frequencies of the altissimo register. They provide the necessary resistance and stability to make those high notes speak clearly rather than sounding like a squeak.
What is the best mouthpiece for a student auditioning for All-State?
For high-stakes auditions, we recommend the Vandoren BD5 (Black Diamond) or the M13 Lyre. These provide the dark, centered, and “professional” sound that judges look for in top-tier student players.
How long does a high-quality student mouthpiece typically last?
A high-quality ebonite mouthpiece can last for many years, often through high school and well into college, provided it is cleaned regularly and not dropped. However, the facing can wear down over thousands of hours of play, so some professionals replace theirs every 3 to 5 years.
Conclusion: Our Final Recommendation
After reviewing the top contenders, we firmly stand by the Vandoren CM302 5RV Lyre Bb Clarinet Mouthpiece as our final recommendation for high school students. It is the ultimate “bridge” mouthpiece—it takes the reliability of the classic 5RV and adds a layer of flexibility and openness that allows a student’s musical personality to shine. Our testing showed that it consistently improves tone, pitch control, and ease of play across various instruments. Whether you are aiming for the first chair in your school band or preparing for college auditions, the 5RV Lyre provides the professional foundation you need to succeed.
