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.
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.
Warm, clear sound
