Vandoren Pack BD5 (Clar Bb)

Black Diamond BD5: the Vandoren mouthpiece with a “high-end” spirit

The Vandoren Black Diamond BD5 Bb clarinet mouthpiece holds a special place in the French brand’s range. Its distinctive silhouette and internal design are intended to guide the air column efficiently and promote a focused sound. Vandoren is a reference among clarinetists for the consistency of its mouthpieces, ligatures and reeds. With the Black Diamond series, the brand offers a refined playing experience that combines ease of blowing, precision and tonal richness.

This pack brings together the essentials for playing straight away under good conditions: the BD5 mouthpiece, the M/O ligature with its plastic mouthpiece cap, and a box of 10 Traditional reeds in strength 2.5. It is a consistent solution for equipping or replacing the mouthpiece setup of a Bb clarinet.

A set for classical clarinetists, from the conservatory to the stage

The Vandoren BD5 is primarily aimed at intermediate, advanced or demanding clarinetists looking for a mouthpiece that offers a controlled playing feel. It is particularly well suited to conservatory studies, chamber music, wind orchestra and solo repertoire—settings in which intonation, consistency and the finesse of attacks play an essential role.

Its balanced response makes it possible to maintain an even emission in delicate passages, both at low dynamics and in more sustained passages. Traditional reeds in strength 2.5 represent a versatile compromise for many musicians: they offer enough flexibility to make attacks easier, while retaining sufficient stability when the playing requires greater projection.

A round, compact sound focused on precision

With its 1.13 mm tip opening, the BD5 offers a measured resistance and excellent breath control. The opening corresponds to the space between the end of the reed and the tip of the mouthpiece: it directly influences the amount of air required, playing flexibility and tonal color. Here, it promotes precise emission and good stability across all registers of the Bb clarinet.

The medium-length top, meaning the flat surface on which the reed rests, contributes to the mouthpiece’s overall balance. It helps produce clear attacks, articulate phrasing and a seamless transition between the low, middle and high registers. The tone remains round, full and focused, with compact projection that retains presence without becoming aggressive.

Made of ebonite, the mouthpiece provides comfortable contact in the mouth and a consistent feel beneath the reed. Its finishing combines polished areas with a raw top to ensure reliable reed support on the mouthpiece. This detail contributes to response stability, intonation precision and control over dynamics.

The Vandoren M/O ligature effectively completes this set. Its role is to hold the reed against the top without unnecessarily restricting its vibrations. Its light, even tightening helps the reed vibrate freely, promoting a direct response and lively sound. The Traditional cane reeds, meanwhile, provide clarity in the attack, good presence in the low register and pleasing stability in the high register.

Recommended compatible accessories

This pack is intended for Bb clarinet. When the included reeds reach the end of their life, choose reeds for Bb clarinet and gradually adjust the strength according to your embouchure, breath support and instrument. A Bb clarinet swab is also recommended after each playing session: it helps remove moisture from the instrument’s body and preserve the mouthpiece, ligature and reeds over time.
