Traditional StyleThe beak on the CM318 Mouthpiece is of a traditional design, meaning that the taper of the mouthpiece happens closer to the edge of the mouthpiece and at a greater angle. This has been a tried and tested method of mouthpiece design for many years and is a popular style chosen by many of the great artists.5RV DesignThe M30 Mouthpiece is very similar to the 5RV but has a larger tip opening and a longer facing. This in turn makes the mouthpiece even easier to blow through but at the same time offers a huge amount of flexibility with a fantastic sound. This is a top quality mouthpiece that will massively improve the intermediate or professional clarinettist?s tone. This mouthpiece has been designed to take harder reeds for the greater clarity and tone that this mouthpiece can offer.Features/SpecificationsTip Opening: 1.150mmFacing Length: LongSuitable For: Bb and A ClarinetRecommended Reed Strength: 3 4
