| 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 Great tone color flexibility with rich, focused core Excellent projection in any venue Accurate intonation Comfortable, quick response 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. |
| Available feature |
| The YHR-667 horn is available with a detachable bell (YHR-667D). |
