SchilkeSymphony M Series Trumpet Mouthpiece in Silver M3D Silver
1/8
Independent shopping perspective
The Korena take
Schilke Symphony M-series trumpet mouthpiece: number 3 rim slightly reduced, standard bowl C cup, 24 throat, tighter Schmidt backbore. For players wanting a compact, resistant feel.
Strong match
Who this is for
- Players who want a centered, compact feel with real resistance behind it
- Symphonic playing where a medium-depth bowl C cup fits
- Anyone on the M3 who finds that backbore too open
Consider the trade-offs
When to look elsewhere
- Players chasing a free, open blow; the M3 star model does that
- Lead work needing a shallow, bright cup for projection
- Cornet or flugelhorn, which take different shanks entirely
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
24 throat
The same throat as the M-series star models. The added resistance here comes from the backbore, not the throat.
Detail 03
Tighter Schmidt backbore
Narrower than the large Schmidt backbore on the star models, so the horn pushes back more and feels compact.
Detail 04
Standard bowl C cup
Medium-depth bowl shape. General-purpose rather than a shallow lead cup or an extra-deep symphonic one.
Detail 05
The D suffix
Across this series, D means the standard bowl C cup with a 24 throat and the tighter Schmidt backbore.
Detail 06
Silver plating
Finish only. Slightly more grip against the lip than gold, and it needs occasional polishing.
Final check
Know before you order
- 01Mouthpiece only. No pouch, case, or cleaning brush included.
- 02If you want a more open feel, the plain M3 shares this rim and cup.
- 03Backbore changes take time to adapt to. Give it a couple of weeks.
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What does the D mean in M3D?
It marks the standard bowl C cup with a 24 throat and the tighter Schmidt backbore, on a slightly smaller number 3 rim. More resistance and a more compact feel than the M3.
02M3D or M3C?
The M3C uses a tighter 27 throat with a Schilke C backbore. The M3D keeps the 24 throat and gets its resistance from the Schmidt backbore instead. Different feel, similar cup.
03Is this a lead mouthpiece?
No. It uses a standard bowl C cup rather than a shallow one, and the tighter backbore is aimed at a balanced, compact feel rather than maximum brightness.
04How does it compare to the M2D and M150D?
All three share the standard bowl C cup, 24 throat, and tighter Schmidt backbore. The difference is rim diameter: the M2D uses a number 2, the M150D a 150, and this one a number 3.
