No lights, no problem

What's that in the street, a head?

What entails entrails, torn out by nails?

Play that Devil's chord, it's said,

Summon the thing with horns and scales.

Diabolus in Musica, the dominant 7th,

Goes from the 3rd to the 7th-flat;

Violating Commandments, first through tenth

To send us lemmings to Hell and back.

When tritone sounds, relegate treat as downbeat;

Reinstate Hallow's Eve forsaken dread.

Approach each door, unlit, in mortal deceit,

Ring the bell and show up dead.
