Detail 01
.700 inch (17.78 mm) cup diameter
Schilke's large end of the standard range. More lip in the cup means bigger sound, but endurance drops fast if your chops aren't there.

SchilkeStandard Series Cornet Mouthpiece Group II in Silver 20 Silver
Independent shopping perspective
The Korena take
Large-diameter cornet mouthpiece in silver plate. For a settled, strong embouchure that wants volume of sound — not a first mouthpiece.
Strong match
Who this is for
- Experienced cornet players with a developed, robust embouchure
- Brass band or concert work where volume of sound matters
- Players stepping up from a smaller rim for more body
Consider the trade-offs
When to look elsewhere
- Beginners still building chops — .700 inch is a lot of rim
- Lead and high-register work, where a shallow cup helps more
- Trumpet players — this is cut for a cornet receiver
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
26 throat
The standard bore across most of this line. Free-blowing and clear rather than resistant, so air moves without much back pressure.
Detail 03
Standard Series profile
Normal wall thickness, not the heavyweight blank. Quicker response and no added mass hanging off the leadpipe.
Detail 04
Silver plating
A bit more grip on the lip than gold. It wears at the rim contact point over years of daily playing.
Detail 05
Cornet shank, Group II
Cornet receivers vary by instrument. Confirm your cornet takes the Group II taper before ordering.
Final check
Know before you order
- 01Mouthpiece only — no pouch, case, or cleaning brush included
- 02A new rim size needs two weeks before your judgment of it is reliable
- 03Jumping straight to .700 from a small cup usually costs endurance first
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 built with a cornet shank. A trumpet receiver takes a different taper, and forcing the fit gives you neither a seal nor good intonation.
02Is the 20 too big for a student?
For most students, yes. The 20 is aimed at a robust embouchure. A smaller diameter like the 15 or 16 is the more usual starting point.
03What's the difference between the 20 and the 22?
The 22 is .710 inch against the 20's .700 — same idea, slightly larger inside diameter. If the 20 already feels near your limit, the 22 will be past it.
04Does the silver plating change the sound?
Plating is mostly about feel and wear. What you notice is grip at the rim, not tone. The cup diameter and throat are what change how it plays.
