The Traditional B40 Lyre is part of the industry-standard clarinet-mouthpiece range from Vandoren, and has a traditional beak design.
The difference between Traditional and Profile 88 mouthpieces is in the exterior angle of the beak. The musician is free to choose the model which suits his or her purpose in terms of best playing position, easiest sound projection, greatest playing comfort, and the most controllable and precise articulation.
The B40 Lyre is the perfect blend between a round sound and rich tone colour. Easy blowing especially in the upper register, it has a 117.5 (1/100 mm) tip opening and a long facing length.
