Description 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 891 is an F/Bb /high F triple horn. 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. Hand-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, Phospher-bronze Rotors: Hollow, phosphor-bronze rotors provide a quick, free response are extremely corrosion resistant. Innovative 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.
