Independent shopping perspective
The Korena take
Heavyweight Schilke trumpet mouthpiece, silver plated, in a 15 size. Extra mass for players who want a more focused, stable sound.

- Trumpeters moving up from a standard-weight Schilke of the same number
- All-around playing where a free-blowing, clear tone matters
Consider the trade-offs
When to look elsewhere
- Players who want quick, light response from a thin-walled mouthpiece
- Beginners still settling on a basic rim and cup
- Anyone needing a dedicated shallow lead piece
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
Heavyweight profile
Extra brass mass damps vibration and tightens the core of the sound, at the cost of some immediate response.
Detail 03
26 throat
Schilke's standard throat on medium models. Balanced resistance, neither tight nor wide open.
Detail 04
Free blowing design
Less back pressure, so long phrases take less effort, but you get less of a wall to lean on for high notes.
Detail 05
Silver plating
Slightly grippier on the lip than gold. Some players react to silver against skin.

Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What is the difference between heavyweight and regular Schilke?
The heavyweight has more brass around the cup and shank. It damps vibration for a tighter, more focused sound and steadier slotting. Rim and cup dimensions match the standard model.
02Is a 15 a good all-around size?
The 15 is described as an excellent all-around mouthpiece with a free blowing, clear sound. It sits in the medium diameter range that suits most players.
03What does the A4a designation mean on other Schilke models?
A is a shallow cup, 4 is a semi-flat rim for endurance, and a is a tight backbore. Together they favor upper register work.
04Will this fit a cornet or flugelhorn?
This is a trumpet mouthpiece with a trumpet shank. Cornet and flugelhorn use different shank tapers.
