YamahaStandard Series French Horn Mouthpiece 30B
1/8
Independent shopping perspective
The Korena take
Yamaha's V-cup French horn mouthpiece, matched to an Alexander 8 with a shallower cup. Built around Bb horn playing and a warm, rich sound.
Strong match
Who this is for
- Bb horn players wanting warmth without a heavy, sluggish low register
- Alexander 8 users who want the high range to speak sooner
- Students replacing a worn or unmarked stock mouthpiece
Consider the trade-offs
When to look elsewhere
- Players who need a deep cup for dark, heavy orchestral bottom
- Anyone committed to a U-cup rim feel like the 34C4
- Horn players used to a much wider rim than 16.87mm
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
V shape keeps the tone warm and blending; the shallower depth brightens it and makes upper notes respond faster.
Detail 03
Semi-thick rim
More lip contact spreads pressure, so endurance improves on long sessions. Slightly less bite on fast slurs.
Detail 04
3.90 mm throat
Gives you resistance to push against. Pitch centers more firmly than a wide throat, and it takes less air to fill.
Detail 05
Semi-wide backbore
Keeps the sound open at loud dynamics instead of turning edgy, at the cost of a bit more air.
Detail 06
Standard rim contour
Rounded, no sharp inner edge, so the feel is familiar coming off most factory mouthpieces.
Final check
Know before you order
- 01Mouthpiece only — no pouch, case or brush included
- 02Built around Bb horn; F-horn specialists may prefer a deeper cup
- 03Give it two weeks before judging response and endurance
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What is the Yamaha 30B equivalent to?
An Alexander 8 with a shallower cup. If you play an 8 and want the high register to come easier, this is the close match.
02What's the difference between the 30B and the 30C4?
Cup shape. The 30B is the V-cup. The 30C4 is the U-cup version, matched to a Tilz 39S. Same family, different feel and sound.
03Will this work on a double horn?
It's designed around Bb horn playing, which is the side most double horn players spend the most time on. It plays on both sides of a double.
04Is the 30B a good student mouthpiece?
Yes. The 16.87mm rim and semi-shallow cup are a workable middle ground, and the semi-thick rim helps endurance for players still building chops.
