ABSTRACT:
French horns with four finger valves and one change horn valve, instead of the standard three finger valves and one change horn valve enable play in twelve keys, as well as twelve tones. Point and dimple connections between key levers and rotary valve string bars provide smooth translation of the string bars and smooth rotation of the rotary valve hubs. Screw-on mouthpieces and mouthpipes have smooth identical inner diameters to avoid the airstream disrupting steps of conventional push-in mouthpieces. Cork block mountings between the tubes, valves and slides instead of the standard soldered metal mountings avoid transmission of vibrations between the tubes. Hand straps steady the French horns instead of the usual finger hooks.
