Detail 01
.647 inch cup diameter
Middle of the road width. Enough surface for control, not so wide it drains endurance on long sets.

SchilkeStandard Series Trumpet Mouthpiece Group I 10A4a Silver
Independent shopping perspective
The Korena take
Silver-plated Schilke 10A4a trumpet mouthpiece, .647" shallow-cup lead piece. For players who spend most of their time in the upper register.
Strong match
Who this is for
- Lead trumpet chairs in big band or show pit work
- Players losing endurance above the staff on a deeper cup
- Doubling on a second piece kept just for high parts
Consider the trade-offs
When to look elsewhere
- Orchestral or symphonic playing needing depth and warmth
- Beginners still building tone and low-register control
- Players who want one mouthpiece for everything
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
Shallow A cup
Less air volume behind the lips. High notes speak easier and brighter, low register gets thinner and harder to fill.
Detail 03
Number 4 semi-flat rim
Flatter rim spreads pressure across more of the lip, which is why it holds up over a long night.
Detail 04
27 throat with tight a-backbore
More resistance to push against. Helps the top end lock in, but takes more effort at loud low volumes.
Detail 05
Silver plate
The finish sits against your lip every time you play, so keep it clean and it stays consistent.
Final check
Know before you order
- 01Mouthpiece only. No pouch, case, or cleaning brush.
- 02The 10A4 is the same piece with an open c-backbore if you want less resistance.
- 03Expect a few weeks of adjustment if you're switching rim size.
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What's the difference between the 10A4a and the 10A4?
Same .647" cup and 27 throat. The 10A4a uses a tight a-backbore for upper-register support; the 10A4 uses a standard c-backbore and blows freer.
02Is this a good first mouthpiece?
No. The shallow A cup is built for high playing and makes the low register harder to control. A student is better served by a standard C cup like the 13.
03Will this help me play higher?
It makes the upper register easier to sustain and reduces fatigue. It doesn't add range you haven't built. Tone below the staff gets thinner as the trade.
04Does it fit any Bb trumpet?
Yes, it's a standard trumpet shank and drops into a normal trumpet receiver.
