Sale
Independent shopping perspective
The Korena take
V-cup Bb horn mouthpiece with a 16.87mm rim and semi-shallow cup. For horn players who want a warm sound without fighting the high register.
Strong match
Who this is for
- Bb horn and double horn players wanting a warmer, rounder core
- Students stepping up from a stock student-grade mouthpiece
- Players who want easier upper register than a deep cup gives
Consider the trade-offs
When to look elsewhere
- Players needing a wide, dark orchestral cup — this is semi-shallow
- Anyone with a rim size already dialed in far from 16.87mm
- Trumpet, trombone or tenor horn players — wrong shank entirely
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
Semi-shallow V-cup
The V shape keeps the sound warm while the shallow depth makes the upper register less work than a deep cup.
Detail 03
3.90mm throat
Standard horn throat. Keeps blowing resistance moderate — enough to lean on, not so tight it chokes at volume.
Detail 04
Semi-wide backbore
Opens the sound and adds air volume at loud dynamics. Slightly less resistance than a tight backbore.
Detail 05
Semi-thick rim, standard contour
Spreads pressure across the lip instead of concentrating it. Longer comfortable playing, slightly less articulation bite.
Final check
Know before you order
- 01Mouthpiece only — no case or pouch
- 02Cut for Bb horn; the response changes on the F side
- 03Changing rim size means a re-adjustment period of days to weeks
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit my double horn?
Yes, it uses a standard French horn shank. It's voiced for the Bb side, so the F side may respond slightly differently than with a deeper cup.
02Is this good for a beginner?
Yes. The mid-size rim and semi-shallow cup are forgiving, and the V-cup keeps the tone from getting thin.
03How does it compare to the YAC HR29B?
It's close to the 29B, with a slightly different rim contour that produces a warmer, richer sound.
04Will this help my high notes?
The semi-shallow cup takes less air and effort up top than a deep cup, so the upper register is generally easier.
