.644 inch cup diameter
Small end of this group, which runs up to .673. Less lip inside the cup, so control comes easier than volume.

Independent shopping perspective
The Korena take
Gold-plated Schilke cornet mouthpiece, .644-inch cup with a number 4 semi-flat rim. For cornet players who want the model 9 sound with more endurance.
Strong match
Who this is for
- Cornet players who tire late in long rehearsals or services
- Anyone happy with the model 9 cup but wanting a flatter rim
- Sustained concert and band parts where staying power matters most
Consider the trade-offs
When to look elsewhere
- Trumpet players — the cornet shank won't seat in a trumpet receiver
- Players wanting a wide cup; .644 sits near the small end
- Lead work needing a shallow A cup and tight backbore
What matters in use
The specifications, translated
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 02
Number 4 semi-flat rim
Flatter contour spreads pressure across the lip instead of biting into one spot. That is where the endurance gain comes from.
Detail 03
C cup
Medium depth with volume behind the tone. Fuller than the shallow A cups, not as dark as the funnel E cups.
Detail 04
26 throat
The wider of the two throats used in this series. Freer blow than the 27-throat models built for upper register work.
Detail 05
Gold plating
A surface finish. Cup diameter, rim contour and throat are unchanged by it, so the playing geometry is the same.
Final check
Know before you order
- 01Cornet shank only. Check your receiver first if you double on trumpet.
- 02Mouthpiece only — no pouch, case or cleaning brush included.
- 03Changing rim contour takes weeks to settle. Don't judge it in one session.
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit my trumpet?
No. It's a cornet mouthpiece with a cornet shank and won't seat correctly in a trumpet receiver.
02What's the difference between the 9C4 and the 9?
Effectively the same cup diameter and 26 throat. The 9C4 adds the number 4 semi-flat rim, which is the endurance change.
03Is this a good student mouthpiece?
It plays fine, but .644 is on the small side of the range. Developing players usually start nearer the 13 diameter with a rounder rim.
04Does the gold plating change the sound?
Plating is a surface finish. It doesn't alter the cup diameter, the rim contour or the 26 throat.
