5 ain't bad LOL but you know I seem to remember an interview somewhere where Geoff Tate from queensryche claimed to be able to sing 7...count 'em...7 octaves. I don't know just how true that is, but man. That takes a lot of work. That's like singing the entire range of the piano and then some I think. ( My piano is in storage so I can't cooberate(?) that.)
