The baritone or baritone horn has three or four valves, very similar to the tenor horn. The basic tuning of the baritone is also B, but it is built with a larger bore. The baritone horn is blown with the kettle mouthpiece. A difference to the tenor horn results from the length of the baritone, which is much wider, i.e. is more conical. Furthermore, the baritone sounds a little softer and fuller in the lower registers than the tenor horn.
