Detail 01
Cornet shank
Cornet receivers are narrower than trumpet. This will not seat correctly in a trumpet, even with the same rim number.

BachCornet Mouthpiece Group II 9
Independent shopping perspective
The Korena take
Group II cornet mouthpiece with a 9 rim size — a small, shallow cup aimed at brighter, higher-register playing on cornet.
Strong match
Who this is for
- Cornet players who want a brighter edge on top
- Lead or high-register parts in brass band settings
- Students needing a low-cost spare mouthpiece in the case
Consider the trade-offs
When to look elsewhere
- Players wanting a dark, broad brass band cornet sound
- Trumpet — the shank will not fit a trumpet receiver
- Beginners still building embouchure endurance on a small cup
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 9 rim size
A smaller rim diameter than a mid-size 7 or 5. Easier high notes, less room for the lips to move.
Detail 03
Group II designation
Bach groups cornet mouthpieces by cup and rim family. Group II sits shallower and brighter than the deeper groups.
Detail 04
Shallower cup
Less air volume behind the lips. Notes speak faster and brighter, but the low register thins out.
Detail 05
$65 price
Standard cost for a name-brand brass mouthpiece. Cheaper than a horn upgrade and a bigger tonal change.

Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit my trumpet?
No. This is a cornet mouthpiece with a cornet shank. Trumpet receivers take a different taper, so it will not seat properly.
02Is a 9 good for a beginner?
It is playable, but the smaller rim gives less lip support. Many students start on a mid-size rim and move smaller later if they want it.
03What does Group II mean?
It is Bach's family designation for a set of cornet cup and rim shapes. Group II runs shallower and brighter than the deeper cornet groups.
04Will this make my high notes easier?
The smaller rim and shallower cup usually help the upper register. Endurance and low-register fullness typically suffer in trade.
