Technically, the flugelhorn is the soprano voice of the tuba family (which includes sub-contra bass tuba, contra bass tuba (BBb, CC), bass tuba (F, Eb), euphonium/baritone, tenor horn (whatever this may mean), alto horn, and flugelhorn). I have lusted after a flugelhorn for a number of years, but can't justify to myself acquiring ANOTHER instrument and learning to play it at this point, particularly since I'm devoting all my time to bass trombone now. Also, decent ones with 4 valves and triggers tend to be a bit pricey for the casual user. But I do love the sound. I guess my ideal would be one of the old 4-valve rotary horns (pitched to 440).
