What is the difference between tenors, basses, sopranos, baritones, and altos in comparison to good and evil? The voice of the tenor cuts like a knife and it shines. Baritones are fathers, murderers, and cardinals offering velvety range. Sopranos can twirl through the air ethereally and otherworldly, Queen of the Night, and yet express hysteria and insanity. The darklings sing bass.
