Detail 01
.953-inch (24.38 mm) cup diameter
Sits in the student range, a touch smaller than the 46. Less lip inside the rim, so upper notes take less effort to hold.

Independent shopping perspective
The Korena take
Small-shank trombone mouthpiece, .953-inch cup with a flexible semi-flat rim. Schilke's beginner size, for first-year through early-intermediate players on small-bore tenor horns.
Strong match
Who this is for
- First and second year students on small-bore tenor trombones
- Band players who need clean slurs and register changes
- Replacing a lost or dented student mouthpiece with a known size
Consider the trade-offs
When to look elsewhere
- Large-bore tenor and bass trombones — the small shank won't seat
- Orchestral players after a big sound; the 51 and 53 go larger
- Lead and commercial work — the 42B and 43A favor the high register
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-flat rim, high point near the center
Spreads pressure and keeps the contact point centered, which is why slurs and register jumps stay under control.
Detail 03
15/64 throat
The common Schilke tenor throat. Steady resistance — enough back-pressure that a developing player can control the airstream.
Detail 04
Small shank
Seats in small-bore tenor trombone receivers only. It will not fit a large-bore tenor or a bass trombone.
Detail 05
45 next to the 45B
Same diameter, but the 45B uses a contour rim and more cup volume and is aimed at lead players, not students.
Detail 06
Silver finish
Smooth on the lip and easy to wipe clean. It dulls with time, so wipe it down after playing.
Final check
Know before you order
- 01Mouthpiece only — no pouch, brush or case included
- 02Confirm your horn takes a small shank before ordering; large-bore receivers won't accept it
- 03Players usually outgrow this size; the 47 is the common next step
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is the Schilke 45 good for a beginner?
Yes. It's the size Schilke points beginners toward. The semi-flat rim and moderate .953-inch cup make it manageable while a student's embouchure is still forming.
02What's the difference between the 45 and the 46?
The 46 is slightly larger at .966 inch and is also a beginner size. Same 15/64 throat. Pick the 46 if the 45 rim feels cramped.
03Will this fit a bass trombone?
No. This is a small-shank mouthpiece and bass trombones use a large shank. It also has far too small a cup for bass work.
04What should I move to after the 45?
The 47 is the usual step up — larger cup with good response, tone and intonation, and it works for students and professionals. The 50 suits medium and medium-large bores.
