Why Are Clarinets Wooden: Exploring the Historical and Acoustical Reasons

The clarinet is a popular woodwind instrument that has been around for centuries.

One of the most distinctive features of the clarinet is its wooden construction.

While there are other materials that can be used to make clarinets, such as hard rubber, composite, resin, ebonite, and ABS plastic, wooden clarinets are still the most common.

The type of wood used in clarinet construction is important, as it can affect the sound and tone of the instrument.

Grenadilla wood, also known as African blackwood, is the most commonly used wood for clarinets. This wood is known for its density, which helps to produce a warm, rich sound.

Other types of wood that can be used include cocobolo and Honduran rosewood. However, these woods are less common and can be more expensive.

Why Are Clarinets Wooden?

The clarinet is a woodwind instrument that is widely used in orchestras, military bands, and jazz ensembles.

One of the distinctive features of the clarinet is that it is made of wood, typically grenadilla or rosewood. In this section, we will explore the reasons why clarinets are made of wood.

Historical Background

The clarinet was invented in the early 18th century by Johann Christoph Denner, a German instrument maker.

The first clarinets were made of boxwood, a dense and hard wood that was readily available in Europe at the time.

However, boxwood was prone to cracking and warping, which made it difficult to use for musical instruments.

In the mid-18th century, instrument makers began experimenting with other types of wood for clarinets.

One of the most popular was grenadilla, a dense and oily wood that was imported from Africa.

Grenadilla was found to be an excellent material for clarinets because of its density, which allowed for a rich and warm tone, and its oily nature, which helped to protect the instrument from moisture damage.

Material Properties

There are several reasons why wood is still the preferred material for clarinets today.

One of the most important is the unique sound that wood produces.

Wooden clarinets have a warm and mellow tone that is difficult to replicate with other materials. This is because wood is a natural material that resonates differently than synthetic materials.

Another reason why clarinets are made of wood is that it is a durable material that can withstand years of use.

However, wood is also a delicate material that requires proper care and maintenance to prevent cracking and warping.

This is especially true for grenadilla, which is a protected species that is subject to international trade restrictions.

Clarinet Materials

Clarinet materials have evolved over time, with the majority of clarinets being made from wood. However, there are now several materials used in clarinet construction, including hard rubber, composite, resin, ebonite, and ABS plastic.


The most common wood used in clarinet construction is African Blackwood, also known as Grenadilla. It is a dense, heavy wood that produces a warm and rich sound.

Other woods that have been used in the past include boxwood and ebony, but they are less common today.

Hard Rubber

Hard rubber, also known as ebonite, is a popular material for intermediate and professional level clarinets.

It is a composite material made of rubber and sulfur, and it has a similar sound to wood. Hard rubber clarinets are more affordable than wooden ones and are known for their durability.


Composite clarinets are made of a combination of materials, such as wood and plastic.

They are often used for beginner level instruments as they are more affordable and less prone to cracking than wooden clarinets.


Resin clarinets are made from a synthetic material that is similar in sound to wood. They are lightweight and durable, making them a popular choice for marching bands and outdoor performances.


Ebonite is a type of hard rubber that is often used in the construction of clarinet mouthpieces. It is a durable material that produces a warm and dark tone.

ABS Plastic

ABS plastic is a synthetic material that is commonly used in the construction of beginner level clarinets. It is a durable and affordable material that is easy to maintain.

Overall, the choice of clarinet material depends on the player’s level, budget, and personal preferences. While wooden clarinets are often preferred by professionals for their warm and rich sound, other materials such as hard rubber and resin offer similar sound quality at a lower cost.

Sustainability Concerns

While wooden clarinets have been the traditional choice for many years due to their superior sound quality, there are growing concerns about the sustainability of using wood as a material for musical instruments.

The manufacturing of clarinets demands high-quality wood without any defects or imperfections, which makes the production of clarinets extraordinarily wasteful because many trees are harvested to make only a few clarinets, making this an unsustainable process.

According to a study published in the BioResources Journal, it takes billets totaling a volume of 0.0015 m³ to produce a single clarinet.

This means that many trees are cut down to meet the demand for wooden clarinets. As a result, the use of wood for clarinets has become a topic of concern among environmentalists and musicians alike.

One of the main issues with using wood for clarinets is that the wood used in traditional clarinets, such as grenadilla wood, is currently logged unsustainably.

This could lead to a decline in the future, and it is something that musicians and manufacturers need to consider when looking for more environmentally friendly options.

In addition to the environmental impact of using wood, there are also concerns about the quality of wood used in clarinets.

For instance, clarinetists need to be aware of the humidity and temperature conditions in which their clarinets are stored.

Ideally, a wooden clarinet should have 70% humidity and a temperature of around 70 degrees Fahrenheit.

Another consideration is to warm the clarinet up by pressing it against your body instead of blowing hot air into it, to avoid rapid temperature change. The clarinet should never be left in a car or next to a heater.

Overall, while wooden clarinets have been the traditional choice for many years, there are growing concerns about the sustainability of using wood as a material for musical instruments. Clarinetists and manufacturers need to consider more environmentally friendly alternatives to ensure the longevity of the industry.
