Yamaha CL-5CM Clarinet Mouthpiece

Yamaha CL-5CM — Custom Clarinet Mouthpiece for a Rich, Grounded Tone

The CL-5CM is a custom-series mouthpiece for Bb and A clarinets, crafted from ebonite (hard rubber) to produce a warm, colorful sound with strong projection. Its 1.10 mm tip opening and 21 mm facing length deliver a balanced feel — enough resistance for clean articulation, enough openness for expressive phrasing. This model sits between the brighter 4CM and the more open 6CM in Yamaha's custom range, making it a natural fit for advancing players.

Why Choose the CL-5CM

Ebonite construction gives this mouthpiece a darker, more refined character than standard plastic pieces at a similar tier. It ships as the factory-fitted mouthpiece on most Yamaha custom clarinets, so players moving to a Yamaha pro instrument will find the response immediately familiar. Bb/A compatibility means one mouthpiece covers both instruments.
