Independent shopping perspective
The Korena take
Silver-plated Schilke 17D4 cornet mouthpiece: .682-inch cup with a deep D cup and semi-flat rim, chosen mainly for endurance on long playing days.
Strong match
Who this is for
- Cornet players in brass band or concert band programs
- Long rehearsals and services where lip endurance is the limit
- Players wanting a fuller cup than the shallow A and B models
Consider the trade-offs
When to look elsewhere
- Lead and commercial high-register work; the shallow 15A4 suits that
- Small-diameter preferences, since .682 sits in the medium-large range
- Trumpet players, unless the horn takes a cornet shank
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
Deeper D cup
More cup volume than the B and C cups in the same diameter, which is the main change in feel versus a 17B4.
Detail 03
Number 4 semi-flat rim
Flatter contact patch than the rounded rims, which is what Schilke ties to improved endurance.
Detail 04
26 throat
The standard throat across most of this group, so switching within the series changes rim and cup, not airflow.
Detail 05
Standard backbore
The 17D4D is the same cup with a larger backbore, so this version blows tighter of the two.
Detail 06
Cornet shank
Shorter, narrower taper than a trumpet mouthpiece. It will not seat correctly in a trumpet receiver.
Final check
Know before you order
- 01Cornet receiver only; a trumpet needs the trumpet-shank version
- 02Single mouthpiece, no pouch or case included
- 03Switching rim contour mid-season can unsettle a set embouchure
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit my trumpet?
No. This is a cornet-shank mouthpiece with a shorter, narrower taper. It will not seat properly in a trumpet receiver.
02What does the 4 in 17D4 mean?
It is the rim number. Number 4 is the semi-flat rim, which Schilke lists for increased endurance compared with the rounder contours.
03How is the 17D4 different from the 17D4D?
Same .682-inch cup and D cup depth. The 17D4D adds a larger backbore, so it blows more openly and takes more air.
04Is this a good step up from a stock mouthpiece?
It is a medium-large .682-inch cup with a deep D cup. If your stock piece is smaller and shallower, expect a fuller feel and more air required.
