Vandoren CM301 5RV Bb Clarinet Mouthpiece - Classic Tone Choice

In this review of the Vandoren CM301 5RV Bb Clarinet Mouthpiece the bottom line is straightforward: it is for clarinetists seeking a time-proven, traditional mouthpiece that delivers a centered, familiar orchestral tone. Designed by Robert Van Doren and used by many top artists, this mouthpiece's primary appeal is its balanced sound and reliable response, which makes it a safe, high-quality choice for advancing students, orchestral players and professionals who want a classic Vandoren voice. The review focuses on playability, tonal character and compatibility with common reeds.

Key Features

• Time-proven design: The CM301 5RV follows a long-established Vandoren profile that yields a warm, centered tone favored in classical settings.
• Tip opening 106.5: The specific 106.5 (1/100mm) tip measurement provides a predictable air resistance and clear articulation for players used to medium openings.
• Medium short facing: The facing length produces direct response and control, helping with precise phrasing and dynamic shaping.
• Best with Vandoren #3-#4 reeds: The mouthpiece is voiced to work optimally with Vandoren #3 to #4 reeds, simplifying setup for players who prefer Vandoren reeds.
• Traditional beak: The classic beak shape contributes to comfortable hand placement and the conventional embouchure feel favored by many clarinetists.
• Artist-endorsed pedigree: Designed by Robert Van Doren and used worldwide, the mouthpiece carries a reputation for consistency and musical familiarity.

Who It's For

The CM301 5RV is best for intermediate to professional clarinetists who prioritize a traditional, orchestral sound and consistent response. Players who already use Vandoren reeds or who want a mouthpiece that pairs predictably with #3 to #4 reeds will find setup and tone development straightforward.

Those seeking an edgy, modern or extremely bright solo jazz mouthpiece might look elsewhere; the 5RV favors a classic timbre over highly projected, contemporary color. Beginners who need very easy blowing or unusually large tip openings should consider a different model tailored to early-stage ease of play.
