The Henri Selmer Paris S9 mouthpieces for the saxophone family are machined from hard rubber bar stock and feature a square chamber.

Considered a universal mouthpiece, the S9 is a flexible mouthpiece responding easily over all registers; making it an ideal choice for both classical and studio work.

The S9 series produces a very direct and homogeneous sound, but maintains great flexibility and a balanced sweetness to meet the needs of both students and professionals alike. The square chamber of the S9 series allows for a broader range of sound.
