Buying a Clarinet Mouthpieces: What to Know

Clarinet Mouthpiece Breakdown

Clarinet Mouthpiece Diagram

Body Materials

When speaking of clarinet mouthpiece materials, a general rule of thumb states that the softer the material, the darker and less projecting the sound. A harder material features a bright sound that projects well.

Usually used for student mouthpieces, plastic clarinet mouthpieces are durable and affordable. The tradeoff comes in that the sound can be bright and difficult to focus.

Ebony (Hard Rubber)

Offers a warmer, better focused sound than plastic. Ebonite is the preferred material for classical clarinet players and jazz musicians who do not need a great deal of edge and projection.


Characterized as having very good projection and a bright sound, crystal mouthpieces are excellent for jazz and some outdoor performances. Crystal is very fragile and a soft mouthpiece pouch is highly recommended.


Though rarely used, wood is the warmest but least projecting of clarinet mouthpiece materials. It also proves less stable than rubber or plastic.

Facing & Tip

Where the mouthpiece meets the reed. The length of a clarinet mouthpiece's facing is directly related to the opening of the tip. As a general rule, the longer the facing, the smaller the tip. The reverse is true for short facings. This relationship dictates many important factors for the clarinetist including reed strength, focus of sound and timbre, projection and the degree of "free-blowing." Below is a quick reference guide:

Facing Resistance Flexibility Reeds
Open Tip short high great soft
Medium Tip medium medium medium medium
Advanced Tip long low little harder


Larger chambers offer clarinet players a more full and flexible sound. Smaller chambers provide a greater focus but less upward, dynamic range.


Directs the air column into the mouthpiece's chamber. Higher baffles offer a brighter sound while scooped baffles offer a darker sound.


The outer angle of the beak, or profile, of a clarinet mouthpiece affects the comfort within the embouchure. Some players prefer the lower angle such as the Vandoren clarinet mouthpiece Profile 88 series or a greater angle like the Vandoren Traditional clarinet mouthpiece.
