What do all the markings on my Monette mouthpiece mean?

PREFIX

Mouthpiece names begin with a prefix that indicates the instrument for which the mouthpiece was designed:

• B = Bb trumpet (or cornet)

• C = C trumpet

• D = D trumpet

• E = Eb trumpet

• AP = A piccolo trumpet

• BP = Bb piccolo trumpet

• FLG = flugelhorn

• FL = Flumpet

• TS = Trombone (small shank)

• TT = Tenor Trombone (large shank)

• BT = Bass trombone

RIM SIZE

After the prefix, the first number indicates the rim size. Smaller numbers indicate larger rim sizes, and larger numbers are smaller rim sizes. The B1 trumpet mouthpieces have the largest rims, with B2 mouthpieces being slightly smaller. BL mouthpieces are small ‘lead’ rim sizes.

The letter W indicates a wider-diameter version of a rim. The B2 S3 W is a wider-diameter version of the B2 S3, and the BLW S1 is a wider-diameter version of the BL S1. 

​

CUP DEPTH

Subsequent letters and numbers generally indicate cup depth:

• L = lead (shallow cup)

• LV = lead, very shallow

• LS = lead, shallower

• LD = lead, deeper

• M = medium deep

• D = deep

• FL = ‘Flumpet’ cup, deep and V-shaped

​

CUP VARIATION NUMBERS

Additional markings such as S1, S2, S3, etc., are cup contour design variations. These numbers generally do not indicate anything specific about the size or depth of the cup. Different sizes with the same ‘S number’ are generally not related.
