YamahaStandard Tuba Mouthpiece 67B4
Sale
Independent shopping perspective
The Korena take
Yamaha's 67B4 tuba mouthpiece — a shallower-cup piece sized for F tuba. For players who need clearer upper-register response on a smaller horn.
Strong match
Who this is for
- F tuba players needing high-register clarity
- Doubling from BBb where the stock piece feels sluggish up top
- Quintet work sitting above the staff
Consider the trade-offs
When to look elsewhere
- BBb or CC players wanting maximum low-end weight
- Anyone whose rim size is already dialed in elsewhere
- Beginners who need an all-purpose starter 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
Sized for F tuba
Matched to the smaller bore and higher tessitura of F horns. On a BBb it can feel thin.
Detail 03
Comparable to a Miraphone C3
If you know that piece, this is the reference point. The 67C4 is the non-shallow version of the same idea.
Detail 04
Yamaha 6x numbering
The 64 through 68 range maps roughly to familiar Bach and Schilke sizes, so you can find your equivalent.
Detail 05
$87.99
Standard-line pricing, not a custom or signature piece. Reasonable for testing a cup depth change.
Final check
Know before you order
- 01Mouthpiece only; no pouch, case or brush
- 02Shank taper varies between makers — check it seats fully in your leadpipe
- 03Give it two weeks before judging; cup depth changes take adjustment
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What's the difference between the 67B4 and the 67C4?
Same basic design, but the 67B4 has the shallower cup. B4 favors upper-register response; C4 keeps more depth.
02Can I use this on a BBb tuba?
It'll play, but it's designed for F tuba. On a big BBb the shallow cup usually costs you low-register weight.
03What Bach size is this closest to?
The 67 without the B4 corresponds to a Bach 22. The B4 variant is closer to a Miraphone C3 with a shallower cup.
04Will a shallower cup help my high range?
It generally makes the upper register speak more easily. It won't add range you haven't built with air and embouchure.
