Sale
1/5
Independent shopping perspective
The Korena take
Yamaha's standard 4C mouthpiece sized for alto clarinet, an uncommon instrument. Straightforward replacement for students and school programs.
Strong match
Who this is for
- School programs maintaining alto clarinets in the clarinet choir
- Students replacing a damaged alto clarinet mouthpiece
- Ensembles needing consistent mouthpieces across a section
Consider the trade-offs
When to look elsewhere
- Bass or soprano clarinet players — the sizes differ
- Alto saxophone players; different instrument entirely
- Players chasing a distinctive professional tone
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
Alto clarinet specific
Sized between soprano and bass clarinet pieces. Neither of those will substitute.
Detail 03
Yamaha student line
Molded to tight tolerances, so replacements play close to what the student already knows.
Detail 04
Under $50
Low enough that a school can stock spares rather than sideline a player after a chip.
Final check
Know before you order
- 01Ligature, cap and reeds are not included
- 02Alto clarinet reeds are a distinct size; soprano reeds will not work
- 03Verify you have an alto clarinet, not an alto saxophone or basset horn
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is an alto clarinet mouthpiece the same as an alto sax mouthpiece?
No. They are different instruments with different bores and shanks. An alto sax mouthpiece will not work on an alto clarinet, or the reverse.
02Can I use this on a bass clarinet?
No. Bass clarinet mouthpieces are larger. Yamaha makes a separate 4C sized for bass clarinet.
03Does a ligature come with it?
Not indicated. Assume you will need your existing ligature and cap.
04What makes the 4C a common choice for students?
The moderate tip opening and standard facing make it forgiving. Sound comes out without excessive air pressure or a fully formed embouchure.
