Detail 01
2-1/2 diameter
A wide rim inner diameter. More lip vibrates, so tone opens up but endurance costs more.

BachStandard Series Trumpet Mouthpiece in Silver 2-1/2C
Independent shopping perspective
The Korena take
Bach's most common step-up trumpet mouthpiece. A medium-large cup for players moving off a stock 7C who want more sound and flexibility.
Strong match
Who this is for
- Students outgrowing the 7C that came with the horn
- Concert band and orchestral players needing fuller low register
- Doublers wanting one general-purpose trumpet cup
Consider the trade-offs
When to look elsewhere
- Lead and commercial players chasing effortless high range
- Beginners in their first months still building embouchure strength
- Cornet players — this is a trumpet shank
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
C cup
Bach's medium cup depth. The default reference point — not bright, not dark, works in most sections.
Detail 03
Silver plating
Slicker and firmer against the lip than gold. Some players with silver allergies react to it.
Detail 04
Standard Series
Bach's production line, not a hand-finished or custom-cut piece. Consistent unit to unit.
Detail 05
Trumpet shank
Tapered for a trumpet receiver. Will not seat correctly in a cornet or flugelhorn.
Final check
Know before you order
- 01Mouthpiece only — no pouch, case, or brush included
- 02Expect two to three weeks of adjustment before judging the size
- 03Buy a mouthpiece brush; silver plating pits under trapped residue
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is a 2-1/2C bigger than a 7C?
Yes. Lower Bach numbers mean wider rim diameter, so 2-1/2C is noticeably wider than a 7C. Sound gets bigger, but you work harder for high notes.
02Will this fit my trumpet?
It fits standard trumpet receivers, which covers nearly all Bb, C, and D trumpets. It will not fit cornet or flugelhorn receivers.
03Is silver or gold plating better?
Silver feels grippier and firmer. Gold feels smoother and warmer to the lip. This one is silver, so choose gold only if silver irritates your skin.
04Good for a high school player?
Yes, if they already have solid tone on a 7C. If range is still a struggle, the wider rim will make it harder before it makes it better.
