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.

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.
