Detail 01
Shallow A cup
Small cup volume, so there's less air to fill. Brighter and more compact, with a thinner bottom register.

Independent shopping perspective
The Korena take
Schilke 6A4a cornet mouthpiece: .630-inch cup, shallow A cup, cushion number 4 rim, 27 throat. A high-register specialist for players with a settled embouchure.
Strong match
Who this is for
- Lead cornet parts that sit high and stay there
- Long sets where rim comfort decides how far you get
- A second piece alongside a deeper everyday mouthpiece
Consider the trade-offs
When to look elsewhere
- Developing players still building tone and low register
- The round, warm cornet sound — a funnel cup does that
- Players who prefer a wide rim; .630 inch is small
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
.630 inch cup diameter
One of the smallest here. Less lip vibrates inside the cup, which helps endurance and hurts low-range flexibility.
Detail 03
Number 4 cushion rim
Wide and semi-flat, spreading mouthpiece pressure over more lip. That's what makes long high parts survivable.
Detail 04
27 throat
Tighter than the 26 throat on the standard models. More resistance to push against, which steadies notes above the staff.
Detail 05
Cornet shank
Cut for a cornet receiver. It will not seat correctly in a trumpet or flugelhorn.
Final check
Know before you order
- 01Mouthpiece only — no pouch, case or cleaning brush
- 02Cornet receiver only; it won't fit a trumpet
- 03Coming off a deeper cup, recheck tuning across the full range before a gig
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is the 6A4a good for a beginner?
No. The shallow cup and small rim reward a settled embouchure. In this series the 13 is the one built for students and developing players.
02How does it compare to the 14A4a?
Same shallow A cup and number 4 semi-flat rim, but the 14A4a is .673 inch across against .630 here. The 6A4a is far smaller and more specialised.
03What do the numbers and letters mean?
The number sets cup diameter, the letter sets cup depth — A is shallow — and the number after it is rim contour. A trailing letter marks the backbore.
04Can I use this on a trumpet?
No. It's a cornet mouthpiece and the shank is sized for a cornet receiver.
