Vandoren MOUTHPIECE - CLARINETTE BB - B40 (CM307)

Vandoren B40: A Classic in the Clarinet Mouthpiece Range

A key French manufacturer, Vandoren has established itself over decades as a reference for clarinetists, notably thanks to the consistent manufacturing of its reeds and the research work carried out on its mouthpieces. The B40 fits this logic: offering a reliable, precise mouthpiece that is versatile enough to suit various contexts (daily practice, ensemble, stage). Note: this family of mouthpieces is available with different chin rest angles (traditional and Profile 88), the difference relating to ergonomics and playing position.

For Which Musician and Styles?

The Vandoren B40 is very suitable for intermediate to advanced clarinetists seeking a well-held sound, without dispersion, and clear articulation. It naturally lends itself to the classical repertoire (homogeneity, intonation, stability) but remains relevant in pop, wind ensemble, or orchestra settings whenever a secure sound production and controlled projection are desired. Thanks to its recommended reed strength guidelines, it also helps quickly find a coherent mouthpiece/reed pairing.

Sound and Design

The B40 is announced with a table identical to the B45 but with a wider facing, a choice that promotes stable playing and a comfortable support feel. The result: a compact and centered timbre, a clear response, and good attack clarity, useful for articulated passages and staccato. Its 1.195 mm opening combined with a medium-long table aims for a compromise between flexibility and control, with an accessible sound production that still allows for color shaping.

Manufactured in ebonite (a blend based on natural rubber, sulfur, and linseed oil), a sought-after standard for clarinet mouthpieces: it contributes to a pleasant feel, good stability, and consistent response. Vandoren also pays attention to finishing: a large part of the exterior surface is polished, while the table remains raw to preserve the precision of the contact plane with the reed.

Recommended Compatible Accessories

This mouthpiece is sold without ligature or mouthpiece cap, so plan for a ligature and a mouthpiece cap suitable for a Bb clarinet mouthpiece (standard clarinet size), to protect the reed and secure transport.
