Independent shopping perspective
The Korena take
Small-shank tenor trombone mouthpiece with a narrow rim and medium cup. For small-bore horns and players who want the high register to sit easier.
Strong match
Who this is for
- Student and small-bore tenor trombones with small-shank receivers
- Younger players who struggle with a wide rim
- Commercial and lead parts that stay in the upper register
Consider the trade-offs
When to look elsewhere
- Bass trombone or large-bore tenor — wrong shank size
- Players who need low-register weight and volume
- Anyone already comfortable and secure on a wider rim
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
Bach's number 11
Narrow rim by trombone standards. Less lip in the cup, so high notes take less work.
Detail 03
C cup
Medium depth. General-purpose — enough body for section playing without the low-register drag of a deep cup.
Detail 04
Narrow rim, medium cup together
A common step up from a stock student mouthpiece: easier top end, still usable across normal band parts.
Detail 05
Shank taper
The taper sets the gap to your leadpipe. A mismatched shank sits too deep and kills response.
Final check
Know before you order
- 01Confirm your horn is small bore — check the receiver, not the brand or model name
- 02Mouthpiece only; no pouch or cleaning brush included
- 03Changing rim size mid-season can set your endurance back for weeks
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is an 11C good for a beginner?
On a small-bore student horn, yes. The narrow rim suits smaller embouchures and the medium cup handles most school band parts.
02Will an 11C fit my bass trombone?
No. Bass trombones use a large-shank receiver. This is small shank and will not seat properly.
03Does a smaller rim help with high notes?
Usually. Less lip vibrates in the cup, so the upper register comes easier. The trade is less power and security in the low range.
04Do I need this if my trombone came with a mouthpiece?
Only if the stock piece fights you — poor high notes, rim discomfort, or uneven response. Otherwise there is no urgency to switch.
