I don’t know what it was, in her touch or voice, that made that song the most unearthly I have ever heard in my life, or can imagine. There was something fearful in the reality of it. It was as if it had never been written, or set to music, but sprung out the passion within her; which found imperfect utterance in the low sounds of her voice, and crouched again when all was still.

David Copperfield
