Detail 01
1.010 inch cup diameter
Large for tenor. More lip vibrates, so the low register opens up and the sound broadens.

Independent shopping perspective
The Korena take
Silver-plated large shank trombone mouthpiece, 1.010 inch cup with a wide semi-flat rim. Built for large-bore tenor and orchestral playing.
Strong match
Who this is for
- Large-bore tenor players in orchestra or wind ensemble
- Long symphonic programs where rim comfort matters
- Players moving up from a 47 or 50 who want more sound
Consider the trade-offs
When to look elsewhere
- Small shank horns — the shank will not seat
- Lead and commercial players who want a compact, bright top end
- Beginners; the large cup takes developed air support
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
J throat
Wide bore. Less resistance and more air moves through, which favors volume over easy back-pressure.
Detail 03
Number 4 semi-flat rim
Wider, flatter contact than the plain 51. Spreads pressure for endurance on long programs.
Detail 04
Shallower cup than the 51
Adds some clarity and response at the top without giving up the bowl-cup fullness.
Detail 05
Large shank
Fits large-bore tenor and bass trombones only. Not compatible with small-shank student horns.
Final check
Know before you order
- 01Verify your horn takes a large shank before ordering
- 02Mouthpiece only — no pouch, case, or cleaning brush
- 03The wide J throat needs steady air; expect an adjustment period from smaller pieces
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 bowl cup. The 51C4 is slightly shallower and uses the wider semi-flat number 4 rim, so it responds a little quicker and sits more comfortably.
02Is this suitable for bass trombone?
It's a tenor size. Bass trombonists usually want the 58, 59, or 60, which run from 1.090 up to 1.143 inch with much larger throats.
03Will the J throat make my horn harder to play?
It offers less resistance, so it takes more air to fill. Players coming from a tighter 15/64 or 17/64 throat often need time to adjust their air.
04How does it compare to the 51D?
The 51D has a very large D cup for a full dark tone, favored on euphonium and by strong players. The 51C4 is shallower with the wider number 4 rim.
