Detail 01
16mm cup diameter
The smallest diameter in this line. Less lip vibrates inside the cup, which favors high notes over low-register breadth.

Independent shopping perspective
Gold-plated cornet mouthpiece in the 5B cut: small cup, tight throat, V backbore. For players who want focus and an easier upper register.

What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 01
The smallest diameter in this line. Less lip vibrates inside the cup, which favors high notes over low-register breadth.
Detail 02
A wide rim spreads pressure over more lip. Easier on endurance, slightly less agile for fast slurring than a narrow rim.
Detail 03
The tightest throat here. Adds back-pressure, so the sound focuses and centers, but caps how loud you can push before it bunches up.
Detail 04
Narrows behind the throat instead of flaring. Pulls the sound tighter and forward compared with the open-backbore cuts.
Detail 05
The choice for players whose lips react to silver plate. It also feels slicker, so the piece slides more on a wet lip.
Detail 06
Shorter and smaller than a trumpet shank. Fits cornet receivers only; no adapter is implied.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
No. The cornet shank is shorter and narrower than a trumpet shank and will not seat properly in a trumpet receiver.
Yes. Denis Wick numbers run larger to smaller, so the 5 cup at 16mm is narrower than the 4 at 16.4mm. The B marks the V backbore.
Two reasons: skin that reacts to silver plate, and feel. Gold sits slicker on the lip. Sound difference is small next to cup and throat.
The small cup and tight throat both work in that direction. It costs you low-register width, so it suits players who need range more than depth.
