mellophone
Best instrument ever. It is perfectly balanced between the upper ranges and lower ranges. The best of both worlds. Woman mellophone lines in the last ten years in drum corps rings have notorious scored higher than those made only of men. Mellophone, in the key of F, may sound flat, but it is actually the tone quality (ok, the instrument itself is impossible to play not flat, everyone else tune down). Mellophone's always play the meanest licks and the greatest dynamics. 
TOB Judge: Sopranos suck. Their high notes are so horrific. Wow, that mellophone double E was beautiful. God I love the mellophone.
