Characteristics and origin
Like the euphonium and the alto horn, the brass bell faces upwards in a fashion called Saxorun, and was invented by Adolph Sachs, the father of the Saxophone.
It is mainly used in brass band and brass ensembles and is responsible for mid-bass. Because the tone is soft, it is often used not only for solos but also obligados. The point that the pitch changes using 3 or 4 pistons is the same as trumpet. Nowadays there are instruments for marching that have improved bells.
Saxorun instruments also include tenor horns and baritones.
