Cutting-edge Mouthpiece with Supreme Sound After decades of studying, designing, and crafting mouthpieces, renowned clarinetist Richard Hawkins has partnered with Backun to deliver some of the world's finest clarinet mouthpieces. Perfect for advancing players and professionals alike, Vocalise mouthpieces will ring out with splendid tonal colors in any setting. Each one is made from hard rubber using bleeding-edge technology and design. As a result, the mouthpieces are 100-percent consistent — a feat to which our GearNuts clarinetists can testify. With the H Model, you get an open tip and longer facing that let you push your clarinet to extreme volumes while still remaining stable. Subsequently, this gives you a rich, dark sound with increased projection, smoother intervals, and greater flexibility, allowing you to perform with confidence.Backun Musical Services: reinventing the clarinet one piece at a time Founder Morrie Backun started with a small woodwind repair shop outside of Vancouver, Canada.
