YHR-881 Double Descant Horns
Hand-lapped rotary valves and slides
Rotary valves and slides that have been hand-lapped are airtight and have smooth action.
Articulated key levers
Articulated key levers have responsive motion.
Hammered and annealed bell
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.
Phosphor bronze rotors
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.
Secure note centers
Tonal clarity and flexibility
The tonal clarity and flexibility of the YHR-881 makes it ideal for baroque music, chamber music, and orchestral music because it overcomes the low-range difficulties typical of descant horns by additionally serving as a single Bb horn. The YHR-882 improves on this feature even further by adding the F natural valve to give more body to the tone in the low register.
Long rotor valve
The innovative thumb valve configuration on the YHR-881 replaces linked valves, thereby reducing friction, promoting faster response, producing exquisite sound, and improving hand comfort.
Excellent sound in all registers
The combination of the secure high register, strong projection, and quick attack of the Bb horn with the rich, warm timbre of the F horn make the double horn ideal for most playing situations.
The YHR-881 horn is available with a F natural 6th rotary valve (YHR-882). Both models are available with a detachable screw bell. All models are available by special order only.
