Vandoren 5RV Lyre Series Bb Clarinet Mouthpiece.
Responsive and easy to control in all registers. Like the 5RV, Vandoren 5RV Lyre Bb clarinet mouthpiece is an excellent choice for the advancing student or for general playing. With a slightly more open tip, the Vandoren 5RV Lyre takes a slightly lighter reed, giving the player more flexibility and a more open sound. It also has a longer facing than the 5RV.
