SchilkeStandard Series Trumpet Mouthpiece in Silver Group II 18B4 Silver
Independent shopping perspective
The Korena take
Silver-plated Schilke Standard Series trumpet mouthpiece, 18B4. For a player who already knows they want a wide rim with a semi-flat contour.
Strong match
Who this is for
- Players who've tested Schilke sizes and settled on an 18 diameter
- Anyone wanting a flatter rim that spreads pressure across the lip
- Adding a second piece alongside a smaller lead mouthpiece
Consider the trade-offs
When to look elsewhere
- Beginners still building embouchure — a wide diameter is harder to control
- Players who like a rounded, grippy rim that locks placement in
- Anyone needing a matched cornet or flugelhorn 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
Number 4 rim
Semi-flat contour rather than rounded. Spreads mouthpiece pressure over more lip, which is why it stays comfortable high up.
Detail 03
Standard Series blank
The regular-mass body, not the Heavyweight profile. Lighter in the hand and in the receiver than the HVY version of the same size.
Detail 04
Silver plating
The standard Schilke finish, and the cheaper of the two. Gold-plated versions of Schilke pieces run several times this price.
Detail 05
Trumpet shank
Fits Bb, C and piccolo trumpets with a standard receiver. It will not seat properly in cornet or flugelhorn leadpipes.
Final check
Know before you order
- 01Mouthpiece only — no pouch, case, or brush included
- 02Rim size is personal; a wider diameter takes weeks to adjust to
- 03Keep a mouthpiece puller handy rather than forcing a stuck shank
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What do the numbers and letter in 18B4 mean?
The 18 is cup diameter, the B is cup shape, the 4 is rim contour. Schilke's number 4 rim is a semi-flat profile built for comfort in the upper register.
02Is this good for high notes?
The semi-flat 4 rim is designed to stay comfortable up high. But the 18 is a wide diameter, which most players find harder to drive above the staff than a smaller size.
03Will it fit my cornet?
No. This is a trumpet shank. Cornets use a shorter, narrower shank and it won't seat correctly.
04How is this different from the Heavyweight version?
Same rim and cup dimensions, different blank. The Heavyweight has more metal around the cup and shank, so it feels heavier and more solid in the receiver.
