When it comes time to buy a clarinet, the same question comes up almost every time: does the material really change the sound? Wood, plastic, composite—each option has its supporters, its myths, and its realities. In this guide, we separate fact from fiction to help you choose the instrument that matches your skill level, usage, and budget.
Does the Material Really Influence the Sound of a Clarinet?
The short answer: yes, but not in the way people often think.
In 1874, researcher Victor-Charles Mahillon published an acoustics treatise claiming that it is the bore (the internal profile of the tube) that determines an instrument's timbre, and not the material it is made of. According to this theory, a metal clarinet would produce an identical sound to a grenadilla instrument, provided the internal dimensions were exactly the same.
In practice, experienced musicians absolutely tell the difference. Why? Because the density and internal texture of the wall influence how vibrations propagate, dampen, and reflect inside the body. A dense, fine-grained material like grenadilla promotes a more stable and controlled resonance, and you can hear it.
That said, for a beginner, the difference is often imperceptible. What matters more at this stage is the quality of the keywork, the consistency of the bore, and the reed.
Grenadilla: The Standard for Professional Clarinets
Grenadilla (Dalbergia melanoxylon), also known as "African blackwood," has been the most widely used wood in clarinet making since the late 19th century, and that is no accident.
This tropical wood stands out for its exceptionally high density and very fine grain—two essential qualities for achieving a perfectly smooth internal finish. In practical terms, a grenadilla clarinet produces a compact, centered sound with great projection, which is exactly what clarinetists look for in orchestras or concert bands.
Grenadilla naturally resists moisture well, giving it remarkable longevity when properly maintained. However, it still requires care: you must warm it up gradually before playing, wipe the inside dry carefully after each session, and oil it regularly to prevent it from cracking due to temperature and humidity variations.
Iconic clarinet models include the Buffet Crampon R13, the Yamaha Custom in grenadilla, and the Selmer Signature, all made of grenadilla and destined for intermediate to professional players.
Other Fine Woods: Boxwood, Mopane, Cocobolo
Grenadilla is not the only wood used for clarinets. Other species are making a comeback in high-end ranges, each bringing its own tonal character.
Boxwood is the ultimate historical wood: it was used to make the very first clarinets 300 years ago. Its tone is supple, warm, and highly flexible across the entire dynamic range, from the softest pianissimo to the most powerful fortissimo. Lighter than grenadilla, boxwood is particularly well-suited for chamber music and repertoires requiring deep expressiveness.
Mopane entered the clarinet world about twenty years ago. Comparable to grenadilla in density, it sits acoustically between boxwood and grenadilla: this model stands out for its wide dynamic range, excellent projection, and highly versatile tonal color. It is easily recognized by its characteristic reddish tint.
Cocobolo has a more fibrous structure, giving it a less compact but warmer, more colorful sound. It is often used for bass clarinets and basset horns, where this unique character truly shines.
These rare species are mostly found from high-end manufacturers like Backun, F. Arthur Uebel, and certain premium Buffet Crampon models.
Green Line Composite: Grenadilla That Won't Crack
In 1994, Buffet Crampon launched the Green Line series, a clarinet manufactured not from solid wood, but from a composite material made of 95% recycled grenadilla powder, carbon fiber, and epoxy resin.
The concept: preserve the acoustic properties of grenadilla while eliminating its main flaw—its tendency to crack. A Green Line clarinet does not crack, resists thermal shock, and handles humidity variations much better than a solid wood body. For playing outdoors, in marching bands, or in volatile weather conditions like Quebec winters, it offers a real practical advantage.
Sound-wise, the difference from traditional grenadilla is minor. Some musicians find the Green Line slightly less "round" than a natural wood body; others cannot tell them apart in a blind test. What is unanimously recognized is its reliability under harsh conditions.
There is one downside, however: the composite material is as hard as glass. A drop can shatter it completely—unlike a wood body, which cracks progressively and can often be repaired by a luthier.
You can find several Green Line models in our clarinet selection.
ABS Plastic: Honestly, Who Is It For?
Let's be direct: an ABS plastic clarinet will never sound like grenadilla. Plastic lacks warmth and resonance, producing a tone that is slightly more nasal and bright, especially at high volumes. This is a reality that manufacturers themselves do not try to hide.
However, ABS clarinets have real benefits that would be dishonest to ignore:
-
Shock and moisture resistance: no risk of cracking, simplified maintenance.
-
Insensitivity to temperature changes: the instrument remains stable outdoors just as it does in an overheated classroom.
-
Affordable price: ideal for a first instrument without a major upfront investment.
-
Minimal maintenance: no need to oil the body, no risk of warping.
For a child starting out whose air support and embouchure are still developing, a high-quality ABS clarinet is often the best choice to begin with. The material will not be the limiting factor; it is the quality of the keywork and the consistency of the bore that matter most at this stage.
An often overlooked alternative: serviced used clarinets can sometimes get you a real grenadilla wood clarinet for a budget comparable to a brand-new entry-level ABS model.

Which Material to Choose Based on Your Situation?
You are a beginner or your child is starting out. Go for a well-made ABS clarinet, or explore a used grenadilla clarinet bought from a trusted dealer who has serviced it. Our guide How to Choose Your First Wind Instrument can also help you ask the right questions before investing.
You are an intermediate player progressing quickly. Upgrading to a grenadilla clarinet will become a natural next step. The acoustic difference becomes noticeable as soon as your embouchure and breathing techniques are well established.
You play outdoors often, in marching bands, or wind ensembles. The Green Line composite is a serious option to consider. Its immunity to weather conditions changes everything, especially in Quebec, where temperature drops between a heated room and a parade field in November can be extreme.
You play at an advanced or professional level. Grenadilla remains the industry standard for the vast majority of settings. Exploring alternative woods (boxwood, mopane, cocobolo) can open up new tonal colors depending on your repertoire and style.
Frequently Asked Questions
Are wood clarinets better than plastic ones? Tonal-wise, yes, grenadilla produces a warmer, more centered, and richer sound than ABS. But for a beginner, the difference is often imperceptible, and the benefits of plastic (durability, price, easy care) can easily take priority. The right answer depends on your skill level and playing environment.
What is a composite clarinet? A composite clarinet is made from a blend of materials, typically wood powder, synthetic fibers, and a resin binder. Buffet Crampon's Green Line combines 95% grenadilla powder with 5% carbon fiber, offering the acoustic properties of wood without the risk of cracking.
Why are wood clarinets harder to maintain? Wood reacts to humidity and temperature fluctuations. You have to warm up the instrument gradually before playing, wipe the interior carefully dry after each session, and oil the body at regular intervals. With a plastic or composite clarinet, this maintenance routine is practically non-existent.
What is the best material for a clarinet? There is no single answer. For pure sound quality, grenadilla remains the standard. For durability in challenging conditions, the Green Line composite is excellent. For beginners or casual playing, ABS plastic gets the job done perfectly. The best material is the one that fits your reality as a musician.
Can grenadilla really crack? Yes. A sudden change in temperature, excessive moisture buildup, or failing to warm up the instrument before playing can cause cracks in the wood body. That is why it is essential to always transport the clarinet in its case, avoid leaving it in a cold vehicle, and oil it regularly.
