SchilkeStandard Series Cornet Mouthpiece Group I in Silver 12 Silver
Independent shopping perspective
The Korena take
Schilke's model 12 cornet mouthpiece in silver plate: a medium .657" cup with a standard rim and C backbore, for players wanting an even, all-purpose setup.
Strong match
Who this is for
- Cornet players wanting one mouthpiece that covers most playing
- Stepping up from a stock mouthpiece without changing feel drastically
- Players who want tone flexibility rather than a specialized high-register piece
Consider the trade-offs
When to look elsewhere
- Lead players chasing a screaming top register — the shallow A cups do that
- Anyone needing a large-diameter cup; that starts at model 15 in Group II
- Trumpet players — this is a cornet mouthpiece
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 3 rim
Schilke's standard contour. Rounder than the semi-flat 4 rims, so slips and flexibility come easier, endurance a little less.
Detail 03
C cup
The medium-depth cup. Gives volume and body to the tone rather than the brightness of the shallower A and B cups.
Detail 04
26 throat
Standard bore. Slightly more resistance than the 27 throats on the A-cup models, which helps hold the sound together.
Detail 05
C backbore
The standard taper. Open, free feel, without the extra-large blow of the D or X backbores.
Detail 06
Silver plating
The standard finish. Costs a fraction of the gold-plated pieces in the same series.
Final check
Know before you order
- 01Mouthpiece only — no pouch, case, or cleaning brush included
- 02Group I covers models 9–14; Group II starts at the larger 15 and up
- 03Check your current mouthpiece number first; jumping several sizes takes weeks to adjust
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is the Schilke 12 good for a student?
It works, though Schilke points beginners and developing players toward the 13, which has the same number 3 rim in a slightly larger .665" diameter with a rounder contour for quick response.
02What's the difference between the 12 and the 12A4?
The 12A4 shares roughly the same diameter but uses a shallow A cup, a semi-flat number 4 rim, and a 27 throat — built for endurance and upper register rather than full tone.
03Will this fit my trumpet?
No. This is the cornet version of the model 12. Buy the trumpet model if that's your horn.
04Silver or gold plating — does it change the sound?
It's a finish difference. The cup, rim, throat, and backbore dimensions are what set the response and tone.
