Geyer style wrap
A horn with a Geyer style wrap has the 4th valve on the far end of the other valves with a long thumb lever. It is an open wrap with very few sharp bends in the tubing."Dual Plane Valve"
This patented Yamaha design on the 4th rotor permits a unique tubing configuration and allows smooth, efficient transitions between the Bb and F horns.
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 responsePhosphor 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 mouthpipe 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 mouthpipe
The long mouthpipe delivers remarkably accurate and balanced intonation.Excellent sound in all registers
The combination of the secure high register, strong projection, and quick attack of the Bb horn with the rich, warm timbre of the F horn make the double horn ideal for most playing situations.
