Detail 01
.640-inch (16.25 mm) cup diameter
Narrow. Less lip vibrating inside the rim, so high notes lock in faster and the low register loses depth.

Independent shopping perspective
Schilke's narrow, thin-rimmed French horn mouthpiece, .640-inch cup. Built for first horn playing, where the parts sit high and the rim needs to stay out of the way.

Strong match

What matters in use
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 01
Narrow. Less lip vibrating inside the rim, so high notes lock in faster and the low register loses depth.
Detail 02
Small contact patch. Feels precise and lets you move between registers quickly, but pressure concentrates and lips tire sooner.
Detail 03
Small bore. More back-pressure, so it takes less air to fill and the upper register speaks quickly.
Detail 04
The 29's larger rim is the adaptable choice for developing players. The 27 assumes your embouchure is already settled.
Detail 05
Smooth on the lip and easy to wipe clean. It dulls over time, so a wipe after playing keeps it bright.
Detail 06
Off-the-shelf Schilke sizing, not custom. The number tells a teacher or section mate exactly what you're playing on.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
No. The narrow diameter and thin rim reward a developed embouchure. The 29 or 30 are the more adaptable starting sizes in this series.
The 30 is the original Farkas: wide rounded rim, fairly deep cup, good all-around. The 27 is narrower with a thin rim, aimed specifically at first horn.
The 28. It's the true French model with a small cup and small throat that favors the high register, and Schilke recommends it for descant.
It costs you room down low. At .640 inch this is built around the upper register; if you play low horn, the 31 or 32 have far more cup.
