BARITONE/EUPHONIUM: This is a weapon of mass confusion. Euphonium players are the Rodney Dangerfields of the brass world. Young players especially don't know their place in the band. They double French horns, trombones, saxophones, tubas in octaves, bass clarinets, bassoons... yadda, yadda, yadda! Euphonium orchestral parts are played by the second trombone or worse, the tuba player! For this reason most euphonium......... baritone...(WHATEVER!) players resort to doubling on trombone. This is when they become dangerous.
