TL;DR: Plastic (ABS resin) clarinets are tough, weatherproof, and inexpensive, which makes them the right choice for beginners, young students, and marching band. Wooden (grenadilla) clarinets are what serious students and professionals play, but the tonal advantage comes mostly from better bore design and build quality rather than the wood itself. If you already own a decent plastic clarinet, upgrading the mouthpiece usually improves your sound more, for far less money, than jumping to a wooden instrument too early.
“Should I buy a wood or plastic clarinet?” is one of the first questions parents ask a band director, and one of the first questions adult beginners type into a search bar. The internet answer is usually “wood sounds better, plastic lasts longer,” which is true but not very useful when you are trying to decide where to spend a limited budget.
This guide gives you the honest version: what each material actually does, what it costs to own, who should buy which, and the one upgrade that most people overlook entirely.

What plastic and wooden clarinets are made of
“Plastic” clarinets are almost always made of ABS resin, a dense, injection-molded thermoplastic. It is the same family of material used in protective cases and many durable consumer goods. Good student clarinets from major makers use it because it is stable, easy to machine consistently, and shrugs off temperature and humidity changes.
“Wooden” clarinets are traditionally made of grenadilla, also called African blackwood (Dalbergia melanoxylon). It is extremely dense, oily, and dark, which is why professional clarinets look almost black. Some makers also offer mopane, cocobolo, or other hardwoods, each with slightly different weight and color.
There is also a middle ground worth knowing about. Buffet Crampon’s Greenline instruments are made from about 95 percent grenadilla powder bonded with carbon fiber, which gives the look and feel of wood with far better crack resistance. Some makers use hard rubber (ebonite) bodies for the same reason. These hybrids blur the old wood-versus-plastic line and are worth considering if you play in unpredictable conditions.
Do wooden clarinets really sound better?
Here is the honest answer: professional clarinets are made of wood, and they sound better than student clarinets. But the reason is not primarily the wood.
A clarinet’s sound is shaped overwhelmingly by the geometry of the air column: the bore diameter and taper, the size and placement of the tone holes, how those holes are undercut, and how precisely the whole thing is finished. Acoustic research on wind instruments going back decades has consistently found that the wall material has a much smaller effect on the sound than the shape of the air inside it. Listeners in blind comparisons often struggle to tell materials apart when the bore design is the same.
What wood does offer is a slightly different feel under the fingers, a bit more weight, and a resonance that many players describe as warmer or more “alive.” Those differences are real to the player, but they are subtle. The big jump you hear between a $600 plastic clarinet and a $4,000 wooden one comes from the fact that the expensive instrument has a professionally designed bore, hand-finished tone holes, better pads, tighter keywork, and a far better mouthpiece in the case. If you want a deeper dive into what actually drives tone, our guide to how to improve clarinet tone breaks the factors down.
Pro Tip: When you test a wooden clarinet in a shop, play it with your own mouthpiece and reed. Otherwise you are comparing mouthpieces, not instruments.
Durability, weather, and care
This is where the two materials genuinely diverge.
Wood moves. Grenadilla absorbs and releases moisture, and it expands and contracts with temperature. The classic failure is a crack in the upper joint, often in the first year, caused by playing a cold instrument with warm, humid breath before it has acclimated. Wooden clarinets need a break-in period (short sessions for the first few weeks), thorough swabbing after every session, and stable storage. Many players keep a humidifier in the case during dry winters and avoid leaving the instrument in a car.
Plastic does not care. An ABS clarinet can go from a cold football field to a heated band room without complaint. It will not crack, it does not need oiling, and it tolerates the occasional missed swab. This is why marching bands, outdoor gigs, and beginning band programs run on plastic. It is also why a plastic clarinet makes sense as a second instrument for professionals who play outdoors.
Both materials still need regular maintenance of pads, corks, and keys. If you want a routine, see our clarinet maintenance essentials guide.
Price and resale value
Prices vary by brand and by year, but as a rough map of the market:
- Plastic student clarinets: roughly $400 to $1,200 new from established makers. Well under that on the used market.
- Wooden intermediate clarinets: roughly $1,200 to $3,000 new. This is the classic “step-up” tier for high school students.
- Wooden professional clarinets: roughly $3,500 to $8,000 and up, with A clarinets and matched pairs beyond that.
Resale follows quality. A professional wooden clarinet from a major maker holds value well and can be sold to the next player years later. A student plastic clarinet has modest resale value, though it also has very little to lose. Intermediate wooden instruments sit in between and are often the best value on the used market because so many are sold when students graduate.
Be cautious with very cheap “wooden” clarinets from unknown brands. The material is not the problem; the bore design, keywork, and pads often are, and a repair technician may not be able to make them play well at any price.
Wood vs plastic clarinet comparison table
| Factor | Plastic (ABS) | Wood (grenadilla) |
|---|---|---|
| Sound | Clear and functional; limited mostly by the student-level bore and stock mouthpiece | Warmer and more complex, mostly because of professional bore design and finishing |
| Weather resistance | Excellent; ideal for marching and outdoor playing | Sensitive to temperature and humidity; can crack |
| Care required | Basic swabbing and periodic pad checks | Break-in period, careful swabbing, humidity control, occasional professional oiling |
| Weight | Lighter | Slightly heavier |
| Typical new price | $400 to $1,200 | $1,200 to $8,000+ |
| Resale | Modest | Good for professional models |
| Best for | Beginners, young students, marching band, travel, backup instrument | Committed students, advanced players, professionals |
Who should buy which?
A child starting in school band: plastic, without hesitation. Instruments get dropped, left on buses, and played in gyms. Buy or rent a plastic clarinet from a reputable maker and put the money you saved into lessons and a good mouthpiece.
An adult beginner: plastic is still the sensible first choice, but a well-cared-for used wooden intermediate can be a good buy if you are confident you will stick with it. Adults tend to be gentler on instruments and more consistent about swabbing.
A student two to three years in who is clearly committed: this is the classic moment for a wooden intermediate instrument. Have a teacher or technician check any used clarinet before you buy.
A marching band player who also plays concert band: many students keep a plastic clarinet for the field and a wooden one for concert season. If you can only have one, plastic wins for marching.
A doubler or a professional playing outdoor gigs: a plastic or Greenline clarinet as a second instrument protects your primary wooden one.

The upgrade that matters more than the body
If there is one thing we want you to take from this article, it is this: the mouthpiece that came in the case of a student clarinet is usually the weakest link in the entire setup, and replacing it changes the sound more than changing the body material does.
The mouthpiece is where the sound is born. Its tip opening, facing curve, chamber, and baffle determine how easily the reed vibrates, how the instrument responds, how stable the pitch is, and how much of the tone’s character is even available to you. A student on a plastic clarinet with a well-designed mouthpiece will typically sound better, play more in tune, and progress faster than the same student on a wooden clarinet with a poor stock mouthpiece.
The economics are hard to argue with. A quality beginner mouthpiece such as the Gleichweit Academy costs $70. A professional-level mouthpiece costs around $245. A wooden intermediate clarinet costs $1,200 or more, and a professional one several thousand. If you are deciding between “keep the plastic clarinet and upgrade the mouthpiece” or “buy a wooden clarinet and keep the stock mouthpiece,” the first option wins on sound and saves you a lot of money. Our article on the best clarinet mouthpiece for beginners explains why in detail.
Two smaller upgrades also outperform a body change: matching the reed strength to the mouthpiece (see our reeds for beginners guide), and a well-made barrel, which we cover in how barrels alter resonance.
Pro Tip: Order of upgrades that gives you the most sound per dollar: mouthpiece, then reeds, then barrel, then instrument.
When to move from plastic to wood
You are ready for a wooden clarinet when several of these are true:
- You have already upgraded the mouthpiece and matched your reeds, and you still hit a ceiling in tone or intonation.
- Your teacher or band director recommends it based on your playing, not your enrollment year.
- You are auditioning for honor bands, youth orchestras, or college programs.
- You practice consistently and swab the instrument after every session without being reminded.
- You can store the instrument in a stable indoor environment.
When the time comes, test several instruments with your own mouthpiece and reeds, and have a technician inspect any used instrument for cracks and pad condition before money changes hands.
Key Takeaways
| Point | Details |
|---|---|
| Material matters less than design | Bore geometry, tone-hole finishing, and the mouthpiece shape the sound far more than wood versus ABS. |
| Plastic is the right first clarinet | Weatherproof, crack-proof, low-maintenance, and inexpensive. Ideal for beginners, kids, and marching band. |
| Wood is for committed players | Intermediate and professional wooden clarinets bring better bore design and build quality, with more care required. |
| Hybrids exist | Greenline and hard-rubber bodies offer wood-like playing with far better crack resistance. |
| Upgrade the mouthpiece first | A $70 to $245 mouthpiece improves sound more than a $1,200 body change and works on both plastic and wood. |
| Test with your own setup | Always compare instruments using your own mouthpiece and reed so you are hearing the clarinet, not the accessories. |
FAQ
Can a plastic clarinet sound professional?
A good plastic clarinet with a quality mouthpiece and well-matched reeds can sound very good, and many listeners would not identify it as plastic. It will not have the refined bore of a professional instrument, but it can take a student a long way.
Do all wooden clarinets crack?
No, but the risk is real, especially in the first year and in dry winter climates. Careful break-in, consistent swabbing, and humidity control reduce the risk substantially. Greenline and hard-rubber bodies remove it almost entirely.
Is a Greenline clarinet wood or plastic?
Neither in the traditional sense. It is compressed grenadilla powder bonded with carbon fiber, so it plays and looks like a wooden clarinet but resists cracking like a synthetic one.
Can I use the same mouthpiece on a plastic and a wooden clarinet?
Yes. Standard Boehm-system B♭ clarinets share the same mouthpiece and barrel fit regardless of body material, which is one reason the mouthpiece is such a smart first upgrade: it moves with you when you eventually change instruments.
Are wooden clarinets heavier?
Slightly. Grenadilla is denser than ABS, so a wooden clarinet feels a bit heavier in the hands. Most players adjust within a few days, and a neck strap or thumb rest cushion helps younger students.
Make the clarinet you own sound better
Whether you play plastic or wood, the fastest route to a better sound runs through the mouthpiece. The Gleichweit Academy B♭ mouthpiece gives developing players a responsive, stable, professional-quality setup for $70. Players ready for a professional mouthpiece can compare five tip openings at home with the Variety Mouthpiece Test Box and keep only the one that fits. And if pitch and resonance are your main frustrations, the Gleichweit B2 barrel in 64, 65, or 66 mm fits any standard Boehm B♭ or A clarinet, plastic or wood.
Buy the body that fits your life and your budget. Then give it a mouthpiece that lets it sing.
