SchilkeStandard Series Cornet Mouthpiece Group I in Gold 13A4 Gold
Independent shopping perspective
The Korena take
Gold-plated Schilke cornet mouthpiece, shallow A cup with an open c-backbore. For cornet players who want upper-register ease and a free-blowing feel.
Strong match
Who this is for
- Cornet parts that sit high and need the notes to speak easily
- Players who find the tight a-backbore of the 13A4a stuffy
- Long sets where a flatter rim keeps the chops fresh
Consider the trade-offs
When to look elsewhere
- Traditional brass band tone; the deep funnel E cups suit that
- Beginners, who do better on the rounder number 3 rim models
- Players chasing a warm, weighted low register
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
Less air to fill, so high notes come easier and the sound brightens. It is a lead voice, not a round cornet voice.
Detail 03
c-backbore (standard)
Free-blowing. The 13A4a shares this cup but uses a tight a-backbore that pushes back harder and narrows the sound.
Detail 04
27 throat
Wider than the 26 throat on most models here, so more air passes through with less resistance behind the lips.
Detail 05
Number 4 semi-flat rim
Wider bearing surface than a round rim, spreading pressure across more lip. That is what buys the endurance.
Detail 06
Gold plating
A surface finish only. Cup, rim and backbore dimensions match the silver 13A4 exactly.
Final check
Know before you order
- 01Cornet shank. It will not seat properly in a trumpet receiver.
- 02If you want more resistance from the same cup, the 13A4a is the piece.
- 03A shallow cup on cornet is a lead choice, not a brass band one.
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit a trumpet?
No. This is a cornet mouthpiece with a cornet shank. Schilke makes the same 13A4 dimensions in a trumpet version if that is what you need.
02What is the difference between the 13A4 and the 13A4a?
Identical .660 inch cup diameter, shallow A cup and number 4 rim. The 13A4a adds a tight a-backbore for a lead feel; this one uses the standard c-backbore and blows freely.
03Is gold worth it over silver?
The cup, rim and backbore are the same as the silver 13A4. You are paying for the plating on the surface, not for different playing dimensions.
04Is this a good first cornet mouthpiece?
Not really. Schilke lists the 13, with its C cup and rounded number 3 rim, for students and developing players. The shallow A cup here assumes a set embouchure.
