Independent shopping perspective
The Korena take
Vandoren mouthpiece for contrabass clarinet, model CM370. A specialist replacement for a school or professional contrabass horn.
Strong match
Who this is for
- School programs replacing a damaged mouthpiece on a shared contrabass
- Low clarinet specialists who want a known, repeatable piece
- Restoring an older contrabass clarinet missing its original mouthpiece
Consider the trade-offs
When to look elsewhere
- Contra-alto (Eb) clarinet players — different instrument, different mouthpiece
- Bass clarinet — the shank and reed size do not carry over
- Casual doublers who play contrabass a few times a year
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
CM370 model number
The number pins one facing and tip opening, so a school can reorder the identical piece years later.
Detail 03
$581.50
Priced well above soprano clarinet mouthpieces. The instrument is rare and the piece is much larger to make.
Detail 04
Mouthpiece only
Contrabass ligatures and caps are instrument-specific and rarely interchangeable with bass clarinet hardware.
Detail 05
Vandoren
Their contrabass reeds are sized to their own mouthpiece dimensions, so reed fit is predictable.
Final check
Know before you order
- 01Confirm your horn is contrabass, not contra-alto — they are not interchangeable
- 02No reed, ligature or cap included
- 03Contrabass reeds are a specialty order; stock up before a concert cycle
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this work on a contra-alto clarinet?
No. Contra-alto in Eb is a different instrument with a different mouthpiece size. This is cut for contrabass clarinet.
02Why is it so much more expensive than a Bb mouthpiece?
It is a far larger piece for a rare instrument, made in small numbers. Contrabass hardware costs more across the board.
03Does it include a ligature and cap?
No, the mouthpiece is sold alone. Contrabass ligatures and caps are instrument-specific, so confirm yours fits this body before your next rehearsal.
04What reeds does it take?
Contrabass clarinet reeds, not bass clarinet reeds. They are a specialty item, so order them ahead rather than expecting local stock.
