YamahaStandard Series Small Shank Trombone Mouthpiece in Silver 51D
Independent shopping perspective
The Korena take
Small-shank tenor trombone mouthpiece, silver plated, in a 51D — a Bach 5G rim with a deeper cup for a fuller low register.
Strong match
Who this is for
- Tenor trombone players wanting more warmth in the low range
- Concert band and orchestral parts sitting in the lower staff
- Bach 5G players who find the standard cup too shallow
Consider the trade-offs
When to look elsewhere
- Large-shank trombones — this is a small-shank taper only
- Lead and commercial players who need bright projection
- Bass trombone, which needs a much larger 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
51D deeper cup
Deeper than the standard 5G. Rounder, darker sound and stronger low register; slightly more air required.
Detail 03
Bach 5G rim comparison
The rim size matches a familiar reference point, so the switch changes cup depth without changing how the rim feels.
Detail 04
Silver plating
Slightly firmer grip and a marginally more focused feel than gold plate. Some players react to silver on the lips.
Detail 05
Standard series
Yamaha's production line rather than a custom shop piece — consistent dimensions at a lower price point.
Detail 06
51 vs 51B vs 51D
Same rim family, different cup depths. 51B is shallower and brighter, 51 standard, 51D deepest and darkest.
Final check
Know before you order
- 01Measure your receiver — large-shank horns need a large-shank mouthpiece instead
- 02No pouch or case included
- 03Silver plating wears over years of play and can be replated
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit my large bore trombone?
Only if it has a small-shank receiver. Many large-bore tenors use large shanks. Check your current mouthpiece shank before ordering.
02What's the difference between 51D and 51B?
Same rim, different cup. The 51D is deeper for a darker, fuller low end; the 51B is shallower and brighter with more edge on top.
03Is this good for bass trombone?
No. Bass trombone uses a substantially larger mouthpiece, usually large shank. A 51D is sized for tenor.
04Does silver plating change the sound?
The effect is small. Most of the difference you feel comes from the rim and cup, not the plating. Grip and feel differ slightly.
