The handmade 891/892 triple horns offer a combination of the rich beautiful sound of a full double French horn, coupled with the sure attacks and control of a descant horn; the problems of intonation and response usually associated with triple horns have been completely eliminated. Yamaha’s patented long rotor and dual plane valves, along with an ingenious tubing configuration, create a unique new shape and size for these horns. And the comfortable balance of their well thought-out designs make these traditionally unwieldy instruments easy to hold and play. The 891 is an F/Bb/high F triple horn and the 892 incorporates an A plus stop valve.
