Clarinet Mouthpiece: A Complete Buyer's Guide

Choosing a clarinet mouthpiece involves understanding a small number of specifications that have a significant effect on how the instrument plays. This guide covers the key decisions: material, tip opening, facing, and brand, with recommendations for players at each level.

What to Prioritise

For most players, the most important specifications are the tip opening and the facing curve. These determine the reed strength you will use and the kind of tone the instrument produces. A medium-closed tip opening is the starting point for classical clarinet playing — it pairs well with medium reeds (2.5–3.5) and gives a controlled, centred tone. Wider tip openings require softer reeds and are used for jazz or more projecting styles. Do not choose a clarinet mouthpiece based on what a professional uses unless you play at a comparable level — many professional choices suit advanced embouchures that beginners have not yet developed.

For beginners and intermediate players, the Vandoren B40 is the most widely recommended starting point — it is the most popular classical clarinet mouthpiece in the world and works well with a wide range of reeds and embouchures. The Vandoren M30 is slightly more open and preferred by many orchestral players. The 5RV Lyre is a shallower-chambered option suited to players who prefer a brighter sound. For jazz, the BD5 or a Rico Royal is worth considering. Clark W Fobes, Backun and Selmer all produce quality options at higher price points. Avoid the mouthpiece that comes with a student instrument — it is a functional placeholder.

How to Match Reed and Mouthpiece

The relationship between the clarinet mouthpiece tip opening and reed strength is the most important pairing to understand. As a general rule: a narrower tip opening requires harder reeds; a wider opening requires softer reeds. If you find you are biting to control the sound, your reed is too soft for your mouthpiece, or your mouthpiece is too open. If you cannot produce sound without excessive effort, your reed may be too hard. A professional or teacher can assess this in a single lesson. See our setup guide for the practical details of fitting reed and ligature correctly.

Frequently Asked Questions

How much should I spend?

A quality hard rubber mouthpiece from Vandoren typically costs between £30 and £80 in the UK — enough to represent a meaningful upgrade from a student mouthpiece without requiring a large investment. Professional-grade mouthpieces from Clark W Fobes or Backun can cost significantly more but offer refinements that are meaningful only at advanced levels. For most players, the Vandoren B40 at the lower end of this range is the most cost-effective choice.

Should I try before I buy?

If possible, yes — especially if you are spending more than £50. A specialist woodwind shop will allow you to compare mouthpieces with your own reeds. Online purchases can be returned at reputable retailers if the mouthpiece is unused. Be aware that assessment takes time; a mouthpiece may feel different after a week of playing than on a five-minute trial.

Is an expensive mouthpiece always better?

No. The best mouthpiece is the one that suits your embouchure, playing style and the reeds you use. Some professional players use relatively inexpensive mouthpieces. Price reflects manufacturing precision and materials, not necessarily suitability for your setup. A medium-priced Vandoren will outperform an expensive mouthpiece that does not suit your embouchure.

How do I know when to upgrade?

The time to consider a mouthpiece upgrade is when your technique is consistent enough that the equipment is the limiting factor — typically when you have been playing for at least two to three years and are working on tone quality at an intermediate level. Before that point, technique development matters far more than equipment. A teacher is the best person to advise on whether a mouthpiece change would help.
