Independent shopping perspective
The Korena take
Cornet mouthpiece with a .675" rim and a semi-flat number 4 rim contour. For cornet players who want the model 15 feel with more endurance.
Strong match
Who this is for
- Brass band cornet players working long rehearsals or services
- Trumpet players doubling on cornet who want a familiar small rim
- Anyone whose chops fade before the end of a set
Consider the trade-offs
When to look elsewhere
- Trumpet — the shank is cut for cornet receivers
- Players wanting a big, broad orchestral sound from a large rim
- Anyone who prefers a rounded rim edge for flexibility
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
Spreads pressure over more of the lip. Comfort holds up on long jobs, but flexibility between registers costs a little more work.
Detail 03
26 throat
Schilke's standard cornet throat. Keeps normal resistance behind the sound, so response stays quick rather than open and airy.
Detail 04
Cornet shank
Shorter and thinner than a trumpet shank. Will not seat correctly in a trumpet receiver.
Detail 05
Silver plating
Standard plating with a slightly grippier feel than gold. Tarnish is cosmetic and polishes off.
Final check
Know before you order
- 01Mouthpiece only — no pouch, case or cleaning brush included
- 02Confirm your horn is a cornet, not a trumpet, before ordering
- 03Coming off a rounder rim, expect a few days to reset
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What is the difference between the 15C4 and the plain 15?
Same .675" cup diameter and 26 throat. The 15C4 swaps in the number 4 semi-flat rim, which trades some flexibility for endurance.
02Can I use this on a trumpet?
No. Cornet shanks are shorter and narrower than trumpet shanks and will not seat properly in a trumpet receiver.
03Is this a good size for brass band?
It sits at the small end of Schilke's cornet range, which suits players who need a secure upper register. Larger models like the 17 or 18 give more sound.
04What does the 4 in 15C4 mean?
It is the rim number. Number 4 is Schilke's semi-flat rim, with a wider, flatter contact area than the standard rim for improved endurance.
