Brass Mouthpiece 101

7C, 5C, 3C—what do these numbers and letters mean? Good question. The number indicates the diameter of the mouthpiece cup and the letter refers to the cup’s depth. The higher the number, the smaller the mouthpiece diameter is. The closer to "A" in the alphabet the deeper the cup is. Therefore a B cup is deeper than a C cup. A shallow cup will allow for a brighter sound and easier upper register and a deeper cup offers a richer tone but can be more taxing to a players embouchure.

We suggest beginning students start on a 7C mouthpiece!
