What matters in use
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 01
Cut for A=440 pitch. Plays slightly flatter than standard Vandoren pieces, which suits American ensemble tuning.
Detail 02
Longer facing with a medium-open tip. Free-blowing with a broad sound, and forgiving on reed strength.
Detail 03
Sized for Bb soprano clarinet. Not for bass, alto, Eb, or A clarinet unless the barrel matches.
Detail 04
Standard clarinet mouthpiece material. Stable in tone, but keep it out of hot cars — it warps and discolors.
Detail 05
Reed engages over more length. Easier low register and smoother legato; staccato takes more deliberate tongue.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
It indicates the mouthpiece is designed for A=440 pitch, the standard in American ensembles. Non-13 Vandoren pieces are cut for the higher European tuning standard.
Usually yes, since Vandoren clarinet mouthpiece bodies are consistently sized. A ligature from a different brand's blank may sit loose or fail to tighten evenly.
It works for advancing students. The medium-open tip and long facing are free-blowing, though the extra air required can tire a very new embouchure.
No. This is a Bb soprano clarinet mouthpiece. Bass clarinet uses a substantially larger mouthpiece with a different bore and reed size.
