Yamaha YCL450M

This clarinet is one-of-a-kind. Perfect for a beginner to intermediate student that is ready to make a sound that only a wooden clarinet can produce, but not experienced enough to care for it. It’s made from grenadilla wood, but features an ABS resin-lined inner bore in the top joint to prevent cracking. Includes silver-plated keys and adjustable thumb rest.

Duet+ Intermediate Series Bb Clarinet, Key: Bb, 65 mm barrel, Grenadilla insert injected ABS resin (upper joint) body, Silver-plated nickel silver keys.

Yamaha clarinets have achieved sound quality and superb intonation by dramatically improving precision and stability. Also to cope with various quality issues inherent in wooden instruments. Duet+ models employ innovative techniques to form a protective layer next to the air column. The combination of precious wood and state-of-the-art resin is not simply a “Duet” of tradition and technology – it’s a “Plus” advantage indeed.

This innovative technology, which premiered with our oboes, has been brought to the clarinet after extensive engineering specific to the instrument. The upper joint body is drilled out slightly larger around the bore and tone-holes. Thermoplastic ABS resin is injected into the cavity, instantly forming the inner shape of a clarinet. It is designed to preserve as much virtue of traditional clarinets as possible, while its natural appearance is hardly distinguishable from conventional all-wooden models.

Silver-plated keys

Silver-plated nickel silver keys give a softer, warmer sound.

New adjustable thumb-rest and strap ring

A new adjustable thumb-rest accommodates different sized hands helping the player develop proper playing technique. In addition, a strap ring allows for the instrument to be held without extra effort. Firmer screws and silver soldered ring gives this new feature excellent durability.

Pivot screw

The YCL-450M incorporates the same taper screws as YCL-650 that makes adjustments easier than ever.

Second register vent tube

A new register vent tube shape improves pronunciation in the second register. Whereas the YCL-450 needs sufficient air pressure for good response, the YCL-450M offers great response, even with low air pressure, making it easy to play even for children.
