The Mezzo mouthpiece is designed for younger, serious students with an eye to affordability. It is also an excellent back-up mouthpiece for outdoor playing. In a double blind test of the top 4 moderately priced mouthpieces (one is actually three times the price of the Gennusa), the Gennusa Mezzo Model received 7 votes as best mouthpiece by 10 prominent professional clarinetists. Made of plastic, rather than the more expensive vulcanized rubber, the Mezzo mouthpieces get the same dark, traditional clarinet sound at an affordable price. Try this one; you will be amazed!
