BachFlugelhorn Mouthpiece - 5C
Independent shopping perspective
The Korena take
Bach 5C flugelhorn mouthpiece. A standard medium-size piece for players who want a step up from whatever came with the horn.
Strong match
Who this is for
- Trumpet players picking up flugelhorn for section or solo work
- Replacing a lost or worn stock mouthpiece
- Students needing a known reference size for lessons
Consider the trade-offs
When to look elsewhere
- Players needing a deep V cup for a very dark sound
- Anyone whose flugelhorn takes a different shank taper
- Lead players wanting a shallow, bright, high-register piece
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
C cup
Medium depth in Bach's lettering. Balanced between range and tone rather than favoring either.
Detail 03
Flugelhorn shank
Flugelhorn shanks are not trumpet shanks. A trumpet 5C will not seat correctly in a flugelhorn.
Detail 04
Rim size vs endurance
A wider rim spreads pressure and can help endurance, but takes more control on high notes.
Detail 05
$65 price
Standard-line pricing. Custom and hand-finished mouthpieces run several times this.
Final check
Know before you order
- 01Flugelhorn shank tapers vary by maker; confirm yours matches before ordering
- 02A mouthpiece that sits too deep or shallow will throw off intonation
- 03If you play a Bach 5C on trumpet, this keeps your rim familiar
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. The shank is cut for flugelhorn and will not seat properly in a trumpet receiver.
02Is 5C bigger or smaller than 7C?
Bigger. In Bach's system the lower number means the larger rim diameter, so a 5C has a wider rim than a 7C with the same cup depth.
03Will it fit my flugelhorn?
Depends on your horn's receiver taper, which varies between makers. Measure or test-fit before buying, since a poor seat affects intonation and response.
04Will this darken my sound?
The C cup is medium depth, so it stays balanced. Deeper cups give a darker flugelhorn sound at some cost to high-register ease.
