YamahaStandard Trumpet Mouthpiece 14C4
1/8
Independent shopping perspective
The Korena take
Yamaha's standard trumpet mouthpiece in a medium cup and rim. A common step up from a stock student mouthpiece, and a reference point for finding your size.
Strong match
Who this is for
- Students moving off whatever mouthpiece came with the horn
- Concert band and orchestral playing where a medium cup fits
- Doublers wanting a predictable middle-of-the-road size
Consider the trade-offs
When to look elsewhere
- Lead players needing a shallow cup for high register
- Players already dialed in on a Bach or Schilke equivalent
- Anyone wanting a heavy-blank or custom-backbore mouthpiece
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
C4 cup and backbore designation
The C cup depth and 4 backbore are Yamaha's most common pairing, so response stays even across the range.
Detail 03
Yamaha comparison chart across the TR line
Lets you jump sideways to a shallower A cup or deeper E cup while keeping a rim you already know.
Detail 04
Standard series, not signature or custom
Machined to Yamaha's production spec. Consistent unit to unit, which matters if you replace a lost mouthpiece.
Detail 05
Trumpet taper
Fits Bb, C and piccolo trumpets and most cornets take a different shank, so check before assuming it swaps over.
Final check
Know before you order
- 01Mouthpiece only. No pouch, case, or brush included
- 02Rim size is personal. A 14C4 may not match your current rim
- 03Silver plating wears at contact points over years of playing
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What Bach mouthpiece is the Yamaha 14C4 closest to?
Yamaha lists the 14C4 as comparable to a Giardinelli 5C. For Bach equivalents in the same line, the 11C4 matches a Bach 7C and the 14B4 matches a Bach 3C.
02Is this good for a beginner?
Yes. It is a standard medium size that works for concert band and lessons, and it gives a teacher a known reference point to adjust from.
03Will this fit my cornet?
No. This is a trumpet shank. Cornets use a different taper, so you need a cornet mouthpiece instead.
04How do I know if I need a deeper or shallower cup?
Shallower cups like the A and B series favor upper register and brightness. Deeper cups like the D and E series favor low register and a darker sound.
