Detail 01
.636 inch cup diameter
Among the smallest in this series. Less lip inside the cup sharpens accuracy up high and narrows the bottom.

Independent shopping perspective
Schilke 28 french horn mouthpiece: .636-inch cup, small cup volume, tight .147-inch throat. A descant and high-register piece rather than an all-around one.

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
Among the smallest in this series. Less lip inside the cup sharpens accuracy up high and narrows the bottom.
Detail 02
Low cup volume gives a brighter, more compact tone. Notes above the staff centre easily; low horn loses body.
Detail 03
The tightest throat in the range. High resistance holds notes in their slot but makes big dynamics work harder.
Detail 04
Descant parts sit high. The small cup and tight throat suit that range instead of fighting it.
Detail 05
The 30 is .670 inch, wide-rimmed and deeper — the all-around choice. The 28 trades that for security up top.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Most players won't want that. The small cup and .147-inch throat favour the high register and thin out low horn parts. Pair it with something deeper.
That's what it's built around, but it works on a double horn for parts that sit high. It's a range choice more than a horn-specific one.
The 27 is .640 inch with a thin rim and a much larger .177-inch throat, aimed at first horn. The 28 is smaller with a far tighter throat.
It helps them centre and hold, since there's less cup volume and more resistance to lean on. Endurance and air support still come from you.
