Detail 01
16.87mm rim inner diameter
Middle of the standard range. Enough room for low-register flexibility without the endurance cost of a genuinely wide rim.

YamahaStandard Series French Horn Mouthpiece 30C4
1/8
Independent shopping perspective
The Korena take
Yamaha's standard-series French horn mouthpiece, voiced for Bb horn: 16.87mm rim, semi-shallow V cup, aimed at a warm sound. A sensible step off a stock piece.
Strong match
Who this is for
- Bb horn players wanting a rounder, warmer tone
- Students replacing an unknown mouthpiece that came with the horn
- Concert band and orchestral section parts
Consider the trade-offs
When to look elsewhere
- Players needing a deep V cup for dark low work
- Anyone committed to a wide rim — 16.87mm is middling
- Descant and high-horn specialists chasing the extreme upper register
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
Centers and slightly brightens the sound compared to a deep cup, and takes some work out of the upper register.
Detail 03
3.90mm throat
Standard bore. Gives you even resistance to push against rather than the loose, free blow of a large throat.
Detail 04
Semi-wide backbore
Opens the sound a little and helps the low register speak without thinning out the top.
Detail 05
Semi-thick rim
Spreads pressure across more of the lip, which helps endurance. Less bite than a thin rim, less agility too.
Detail 06
Designed for Bb horn
Voiced around the Bb side. On a double horn the F side can respond a little differently.
Final check
Know before you order
- 01Mouthpiece only — no pouch, case or cleaning brush
- 02Standard French horn shank; it won't fit mellophone or trumpet receivers
- 03Give it two weeks before judging — the embouchure adapts to a new rim
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01How does 30C4 compare to a 29 or 32?
Within this series the number tracks rim diameter, so higher runs wider. The 30 sits mid-range at 16.87mm. The letters indicate cup shape and depth.
02Is this a real upgrade from the mouthpiece that came with my horn?
It's a consistent, measured rim and cup rather than a generic one. A reasonable first move, not a specialist piece for a particular section role.
03Will it fit a double horn?
Yes, it uses the standard French horn shank. It's voiced for the Bb horn, so expect the F side to feel slightly different in response.
04What's it closest to?
It sits near Yamaha's HR29B with a different rim contour, and its cup profile is comparable to a Tilz 39S.
