YamahaStandard Series French Horn Mouthpiece 29D4
1/8
Independent shopping perspective
The Korena take
Standard-series French horn mouthpiece sized for Bb horn. A semi-shallow V-cup with a warm, rich tone, at a low entry price.
Strong match
Who this is for
- Bb horn players wanting a warmer sound than a shallow cup gives
- Students moving up from a stock beginner mouthpiece
- A second mouthpiece for lighter, higher-register playing
Consider the trade-offs
When to look elsewhere
- Players needing a deep cup for heavy low-register work
- Anyone locked into a U-cup or double-cup rim feel
- Double horn players who play mostly on the F side
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 adds brightness and response on top.
Detail 03
3.90 mm throat
A moderate opening. Enough resistance to hold a center without feeling stuffy at volume.
Detail 04
Semi-wide backbore
Opens the sound and helps it carry, at the cost of a little focus compared to a tighter backbore.
Detail 05
Semi-thick rim, standard contour
Spreads pressure across the lip for comfort on long sessions without deadening the feel of the rim edge.
Detail 06
Designed for Bb horn
Voiced for the shorter Bb side. On an F horn it will feel brighter and less full down low.

Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01How does the 29D4 compare to the YAC HR29B?
It is close to the HR29B but with a slightly different rim contour, which produces a warmer, richer sound.
02Will this work on a double horn?
Yes, but it is designed specifically for Bb horn. On the F side expect a brighter, thinner low register.
03Is this good for a beginner?
Yes. It is an inexpensive standard-series piece with a comfortable semi-thick rim, and it is a clear step up from most stock mouthpieces.
04What is the difference between the V-cup and U-cup models?
The V-cup here gives a warmer, more traditional horn sound. The U-cup versions in this series, like the 34C4, feel and sound different in the cup.
