Detail 01
Deep cup
Covered, mellow tone with a soft attack. The top of the range speaks easily but stays quiet rather than loud.

YamahaStandard Series Flugelhorn Mouthpiece 11F4
Independent shopping perspective
The Korena take
Deep-cup flugelhorn mouthpiece at Bach 7FL size with a thick, semi-flat rim. For trumpet players doubling on flugelhorn who want a mellow sound.
Strong match
Who this is for
- Trumpet doublers playing flugelhorn in a big band or combo
- Ballads and soft playing in the upper register
- Players coming off a Yamaha TR7A4-size trumpet piece
Consider the trade-offs
When to look elsewhere
- Anyone after a bright, cutting flugelhorn sound
- Trumpet use — this is a flugelhorn shank
- Narrow-rim players; the thick flat rim will feel foreign
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
16.24 mm rim inner diameter
Mid-size, matching a Bach 7FL. Most trumpet doublers land on this without rebuilding their embouchure.
Detail 03
4.30 mm throat
Moderate opening. Enough resistance to shape soft playing without choking full-volume passages.
Detail 04
Thick, semi-flat rim
Spreads pressure across more lip. Comfortable over long sets, slightly less precise on fast slurs.
Detail 05
Standard backbore
Keeps the deep cup from turning tubby and holds intonation predictable across the range.
Detail 06
Sized close to the TR7A4 trumpet piece
Switching horns mid-set feels familiar because the rim is close to what you already play.
Final check
Know before you order
- 01Flugelhorn receivers vary — check your horn takes this shank before ordering
- 02Sold as the mouthpiece alone
- 03Coming from a trumpet piece, response feels slower and softer at first
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can I use this on a trumpet?
No. It has a flugelhorn shank and a deep flugel cup. It will not seat properly or play in tune on a trumpet.
02What Bach size is the 11F4?
Bach 7FL.
03How does it compare to the 13F4 and 14F4?
Those sit at Giardinelli 7FL size, with the 14F4 adding rim diameter. The 11F4 is the Bach 7FL size instead.
04Will it help my high register?
It makes the upper register easy to play softly and mellow, not louder. A deep cup favors warmth over projection.
