Detail 01
The 3 in 3C
Sets rim diameter, and it's on the wide side. More lip inside the rim, which suits developing endurance but needs control.

BachStandard Series Trumpet Mouthpiece in Silver 3C
Independent shopping perspective
The Korena take
Silver-plated 3C trumpet mouthpiece with a fairly wide rim and medium cup. The default all-around choice for students and general-purpose players.
Strong match
Who this is for
- Students needing one mouthpiece for band, lessons and jazz ensemble
- Replacing a lost or worn stock mouthpiece on a student trumpet
- Concert and marching work where tone and range stay balanced
Consider the trade-offs
When to look elsewhere
- Lead players chasing high register — a shallower cup gets there easier
- Players wanting a dark, broad orchestral sound from a deeper cup
- Cornet or flugelhorn, which take a different shank taper
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
The C cup
Medium depth. Sits between shallow lead cups and deep orchestral ones, so it doesn't favor high or low register.
Detail 03
Silver plating
Harder and slicker against the lips than bare brass, and it resists wear. A small number of players are sensitive to silver.
Detail 04
Standard Series
Bach's regular production line rather than a hand-finished custom piece, so sizes swap out predictably.
Detail 05
Trumpet shank
Drops into standard Bb and C trumpet receivers. It will not seat correctly in a cornet or flugelhorn.
Final check
Know before you order
- 01No pouch or case included — a hard pouch keeps the rim from denting
- 02Switching rim size resets your embouchure; give it two or three weeks
- 03Check your current size first; many student horns ship with a 7C
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is a 3C good for a beginner?
It works, but many teachers start students on a 7C. The 3C's wider rim gives more lip room and takes more control to center. Fine as a first upgrade once tone is stable.
02What's the difference between a 3C and a 7C?
Cup depth is the same. The 3 has the wider rim diameter, which gives more lip area and a broader sound. The 7 is narrower and often easier on endurance early on.
03Will this fit my cornet?
No. Cornet receivers use a shorter, narrower taper. You need a cornet mouthpiece or a proper adapter.
04How do I clean it?
Warm water, mild soap and a mouthpiece brush through the throat and backbore. Avoid abrasives — they wear the plating off the rim.
