Interestingly enough, a good quarter or more of the works we do in the community chorus, and most of them religious, have a demented fifth tucked away somewhere in them. And that's just counting the bass part.

They're so much more tasty in the lower register!

A demented fifth seeks to resolve itself... I'd be even more interested if you sing any deficient ninths down there. I think you'd be *edging toward a virtual reformation.
