Can't remember tune

[Froogleyboy]

Hey, Playgrounders, I was wondering if anyone remembers the name of this old tune, from back in medevil time, that was banned by the churches because it sounded like the devil, or something like that

Could you be thinking of a tritone interval, which was banned from church music because its dissonance reminded people of the devil?

[Telonius]

Not a tune but an interval: the augmented fourth.
EDIT: Ninja'd - "tritone" is another name for it.

That's it, I new it was Tri- something

[THAC0]

Additionally, the lochrian mode.

Note: This one guy wrote a song called 'the Devil's Trills' based on that interval. I can't remember his name, and am too lazy to look it up.
