YHR-891D

Yamaha's triple horns are handmade and meticulously crafted to perfection by experienced artisans. They offer the rich full sound of a full double horn, coupled with the sure attacks and control of a descant horn. The problems of response and intonation usually associated with triple horns have been completely eliminated. Yamaha's patented 'long rotor' and 'dual plane' valves, along with an ingenious tubing configuration permit the same shape and balance as a conventional horn so they are comfortable to hold and play. The 891D is an F/Bb /high F triple horn.

Specifications

Features

• 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.
   
• Hollow valve rotors
  Hollow valve rotors provide quick, free response.
   
• Phosphor bronze rotors
  Rotors made of phosphor bronze resist corrosion.
   
• Cyclical bore
  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
  Tapered valves wear for a long time without air leakage.
   
• Long leadpipe
  The long leadpipe delivers remarkably accurate and balanced intonation.
   
• Long rotor valve
  The innovative thumb valve configuration on the YHR-891 replaces linked valves, thereby reducing friction, promoting faster response, producing exquisite sound, and improving hand comfort.
   
• Excellent intonation
  The intonation problems normally associated with the triple horn have been eliminated.
   
• Ingenious valve tubing configuration
  The combination of the long rotor valve, dual plane valve, and tubing configuration create a unique shape and size for the triple horn.
   
• Available features
  The YHR-891 horn is available with a 6th rotary A/plus stop valve (YHR-892D). Both models are also available with a detachable screw bell. All models are available by special order only.
