The Yamaha CX Custom professional B-flat clarinet has a full round sound with an immediate clarity to the tone. It has inset toneholes and a silver-plated bell ring, both of which contribute to the presence and openness of its tone.
The designation CX is apparently derived from the word ‘chalumeau’ (pl. ‘chalumeaux’), a predecessor to the Baroque clarinet, as an homage to the traditions of clarinet making.
