The Schilke Mouthpiece Labeling System

When a standard model Schilke mouthpiece has a standard backbore, rim and cup, only the cup diameter (first number) is shown on the mouthpiece to designate the model number. For example, in the case of the model #14 trumpet mouthpiece, it is only necessary to identify the mouthpiece with the first number because it has a standard ‘C’ cup, standard ‘3’ rim and standard ‘c’ backbore. It could be cataloged as a 14C3c but the nomenclature was dropped, since the remaining variables are standard. The model 14A4a has a shallower ‘A’ cup, flatter ‘4’ rim shape, and a tighter ‘a’ backbore than the #14 model.

Regarding the Schilke mouthpiece numbering system,
using the model 14A4a as an example:

14 refers to “Cup Diameter”= smallest numbers have the smallest diameters. Diameter size increases as the number increases.

A refers to “Cup Volume”

A. Small – shallow

B. Medium small

C. Standard (medium size)

D. Medium Large

E. Large

4 refers to “Rim Contour”

1. Roundest

2. Semi-Round

3. Standard

4. Semi-flat

5. Flattest

a refers to “Backbore”

a. Tight

b. Straight – slightly more open

c. Standard

d. Medium Large- slightly curved out

e. Large
