The slide for the stop valve is at the top of the valve cluster. This photo is a close up of my triple, which is a Paxman compensating triple. The most recent recital I gave is probably the first that I actually made much use of my stopping valve (on passages in Alla Caccia by Alan Abbott) and I must say it is just about the best invention ever.Ī stopping valve is most commonly seen on single B-flat horns, descant horns, and some triple horns.
In the United States horns with a stopping valve are not common.
