Vandoren Black Diamond 'BD' Clarinet Mouthpiece


The Black Diamond Ebonite mouthpiece features a new internal and external design. These developments offer the musician a full sound, rich in depth and colour, especially in the upper register of the clarinet.




  • BD4 Black Diamond Bb (CM1004) - Shares the same qualities as the BD5 with remarkable ease of emission and articulation
  • BD5 Black Diamond Bb (CM1005) - The perfect balance between a dark, rich, yet compact sound.
  • BD7 Black Diamond Bb (CM1007) - Characterized by a larger tip opening and volume of sound, while keeping the round and compact sound of the BD5.


The main variation between the mouthpieces comes down to tip opening:

Measured in 1/100mm the  tip openings are as follow:

  • BD5 is113
  • BD4 is115.5
  • BD7 is133
