Detail 01
1.010 inch cup diameter
Large for a tenor piece. More lip vibrates, so the sound broadens, but it takes more air to fill.

Independent shopping perspective
The Korena take
Small-shank silver trombone mouthpiece, 1.010-inch cup, slightly shallower than the model 51 with a wide semi-flat rim. For tenor players wanting size plus endurance.
Strong match
Who this is for
- Tenor trombone players who want a large cup without wearing out
- Section and orchestral work needing a rich, full bowl sound
- Stepping up in diameter from a 47 or 46
Consider the trade-offs
When to look elsewhere
- Horns with a large-shank receiver — the taper won't seat
- Beginners; 1.010 inches is a lot of lip to control
- Lead and commercial playing that wants a shallow, bright cup
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, shallower than the model 51
Gives up a little of the 51's bowl depth for quicker response and less work up high, keeping the same diameter.
Detail 03
Number 4 semi-flat rim
Wider, flatter contact spreads pressure across the lip. That's what makes the large diameter survivable on a long rehearsal.
Detail 04
J throat
Same throat as the model 51, so the blow and airflow feel carry straight over if you're already on that piece.
Detail 05
Small shank
Fits small and medium-bore tenor slides. Large-bore horns take a large shank and this will sit loose or shallow.
Detail 06
Silver plate
Grippier on the lip than gold and it tarnishes with sweat. Wipe after playing rather than polishing hard.
Final check
Know before you order
- 01Confirm your slide takes a small shank before ordering — test-fit or measure.
- 02A larger cup demands more air; give it two weeks before judging endurance.
- 03Keep it in a pouch. A dented shank sticks in the receiver.
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What's the difference between the 51 and the 51C4?
Same 1.010-inch diameter and J throat. The 51C4 has a slightly shallower cup and the number 4 semi-flat rim, so it responds a bit quicker and is easier on the lip.
02Will this fit a large bore trombone?
Only if that horn's receiver is small shank. Many large-bore tenors use a large shank, in which case you need the large-shank version, not an adapter jammed in.
03Is the 51C4 a good euphonium mouthpiece?
It's aimed at tenor trombone. The deep D-cup models such as the 51D and 52D are the euphonium picks, and euphonium receivers often call for a different shank anyway.
04Is 1.010 inches too big for a student?
For most beginners, yes. The 45 and 46 are the sizes built for starting players. Move up to a 51-family diameter once your air and embouchure can fill it.
