YamahaStandard Series Small Shank Trombone Mouthpiece in Silver 51C4
Independent shopping perspective
The Korena take
Small-shank tenor trombone mouthpiece in 5G size with a slightly shallower cup, silver plated. For players who want 5G room without the full depth.
Strong match
Who this is for
- Small-bore tenor trombone in concert band or big band
- Players who find a straight 5G too dark
- Moving between legato ballads and loud full-section parts
Consider the trade-offs
When to look elsewhere
- Bass or large-bore trombones — this is small shank
- Players who want maximum depth and low-register weight
- Alto trombone, which calls for a shallower piece like the 48A
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
A small step shallower than a straight 5G. The sound centers a little brighter and the upper register costs less effort.
Detail 03
Small shank
Fits small-bore tenor slides. It will not seat in a large-shank receiver without an adapter.
Detail 04
Silver plating
Grippier and warmer against the lip than bare brass, and it resists corrosion from skin oils.
Detail 05
Sits between 51B and 51D
The 51B is shallower, the 51D deeper. This one moves only slightly off standard 5G depth.
Final check
Know before you order
- 01Mouthpiece only — no pouch or cleaning brush included
- 02Confirm your receiver takes a small shank before ordering
- 03Wipe the plating down after playing; skin oils are what dull it
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit my bass trombone?
No. Bass trombones take a large shank. This is small shank, cut for tenor trombone slides.
02How is 51C4 different from a plain 51?
The 51 matches a Bach 5G. The 51C4 keeps that rim but takes a slight amount off the cup depth, so it plays a touch brighter with an easier top end.
03Is a 51 bigger than a 48?
Yes. The 48 corresponds to a Bach 6-1/2AL and the 51 to a 5G. The 51 gives you a wider rim and more room in the low register.
04Does the silver plating wear off?
It wears at the rim over years of regular playing and can be replated. Keeping it wiped down slows the tarnish that builds where it contacts skin.
