The Chedeville “Umbra” Bb Clarinet Mouthpiece creates a beautiful dark sound full of rich colors. The Umbra is darker in sound color than our Elite model and also has less resistance, a combination that is seldom found in a clarinet mouthpiece. Because the mouthpiece doesn’t add resistance, you will have no limits in dynamics, colors, or articulation.
