YHR-891 Triple 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.
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.
