Detail 01
17.14mm / .675-inch cup diameter
Wide for a lead piece. More lip vibrates inside the cup, so the sound fills out and low notes come easier.

SchilkeStandard Series Trumpet Mouthpiece in Silver Group II 15 Silver
Independent shopping perspective
The Korena take
Silver-plated Schilke Group II trumpet mouthpiece pairing a wide .675-inch cup with a shallow A cup. For lead players who want high-register help without a pinched rim.
Strong match
Who this is for
- Lead parts in big band or pit work sitting above the staff
- Players with fuller lips who find small lead pieces pinched
- Long sets where a flat rim spreads pressure across the chops
Consider the trade-offs
When to look elsewhere
- Orchestral and legit playing that wants a deep cup for warmth
- Beginners still building embouchure — shallow cups punish inconsistent chops
- Cornet or flugelhorn, which take different shanks
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
Shallow A cup
Brightens the tone and lifts the upper register. You give up the dark core a deeper cup would give you.
Detail 03
27 throat
Slightly more open than a 26. A bit more air moves through, so it blows freer once you push volume.
Detail 04
Number 4 semi-flat rim
Flatter, wider bearing surface spreads mouthpiece pressure over more lip. That is what buys endurance on long sets.
Detail 05
Tight a-backbore
Adds resistance behind the throat. High notes slot faster and the sound stays compact instead of spreading.
Detail 06
Silver plating
Feels grippier on the lip than gold and takes daily handling well. Tarnish wipes off with a polish cloth.
Final check
Know before you order
- 01Trumpet shank only — it will not seat in a cornet or flugelhorn receiver
- 02Mouthpiece alone: no pouch, no case, no cleaning brush
- 03Check the full stamp before ordering — the 15 comes in several cup and backbore variants
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is this a lead mouthpiece?
Yes. Shallow A cup, tight backbore and semi-flat rim all point at upper-register work. The wide .675 cup keeps it from feeling as thin as most lead pieces.
02How does it compare to a smaller size like the 13?
At .675 inch it is noticeably wider across the rim. More lip vibrates, so the tone fills out and low register comes easier, but you work harder to hold it up.
03Will this help me play higher?
It makes the top easier to slot, not free. The shallow cup and tight backbore cut the air needed up there. Your chops still do the work.
04Does it fit my trumpet?
Any trumpet with a standard receiver, yes. Piccolo trumpets take the same shank, though most players want a smaller, shallower piece there.
