YHR-667V

Rotary valves and slides that have been hand-lapped are airtight and have smooth action.

Articulated key levers have responsive motion.

Hammering and annealing are processes so important to the instrument's acoustic characteristics that Yamaha employs computer-controlled equipment to ensure consistently superior sound. Hammering enables bells to have a rich, resonant tone that blends beautifully with other instruments. Annealing is a cooling and heating process that makes it easier to control the acoustics of the instrument.

Hollow valve rotors provide quick, free response

Rotors made of phosphor bronze resist corrosion.

A cyclical bore is a perfectly cylindrical tubing assembly in combination with a conical leadpipe and bell system. This allows for consistent air flow throughout the horn.

Tapered valves wear for a long time without air leakage.

The long leadpipe delivers remarkably accurate and balanced intonation.

The combination of the secure high register, strong projection, and quick attack of the B^b horn with the rich, warm timbre of the F horn make the double horn ideal for most playing situations.

The YHR-667V horn is available with a detachable bell (YHR-667VS).
