Detail 01
Medium shank
Sized for pre-1974 B&H and Willson receivers. It is not the USA small-shank or large-shank taper, and they do not swap.

Denis WickDW5880E Classic Series Euphonium Mouthpiece - Silver, 4AM
1/8
Independent shopping perspective
The Korena take
Medium-shank euphonium mouthpiece, 4AM size, cut to fit pre-1974 Boosey & Hawkes and Willson instruments. Open sound, solid low register.
Strong match
Who this is for
- Pre-1974 B&H or Willson euphonium players needing the correct shank
- Players wanting a fuller low register with clear front on notes
- Doubling trombonists who want a true euphonium cup
Consider the trade-offs
When to look elsewhere
- Most USA and Japanese euphoniums — those take the 4AY shank
- Players after a tighter, brighter sound; the 6BM cup is smaller
- Anyone unsure of their receiver taper — the wrong shank sits badly
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
26mm cup diameter
Large for euphonium. More lip vibrates, which is where the open sound and low-register body come from.
Detail 03
6.72mm rim width
Fairly wide. Spreads pressure and helps endurance on long sustained parts, at some cost in flexibility.
Detail 04
7.38mm throat
Open. Rewards a strong air stream; underblow it and the sound thins out rather than filling.
Detail 05
Barrel backbore
Holds the sound centered and focused instead of letting it spread. Attacks stay clean at the front.
Detail 06
Silver plating
Standard slick finish. A known irritant for a small number of players with silver sensitivity.
Final check
Know before you order
- 01Identify your horn's shank first — 4AM and 4AY are the same cup, different tapers
- 02Mouthpiece only; no pouch or cleaning brush included
- 03A 26mm cup takes air. Expect an adjustment period from a smaller piece
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit a Yamaha or Besson euphonium?
Not reliably. USA and Japanese instruments are the 4AY's target, which uses the USA small shank. The 4AM is cut for pre-1974 B&H and Willson.
02What is the difference between 4AM and 6BM?
The 4AM is bigger: 26mm cup vs 25.40mm, 6.72mm rim vs 6.26mm, 7.38mm throat vs 7.12mm. The 6BM trades size for a clearer high register.
03Is this good for low notes?
Yes. The 26mm cup and open 7.38mm throat are aimed at a focused, full low register with clean attacks.
04Is it too big for a student?
Possibly. At 26mm with an open throat it needs steady air support. A developing player may tire quickly and lose the top end.
