That makes perfect sense of course; therefore, I never thought of it. ;)

I don't want to sing it, as voice is definitely not my strength. But I've been researching it for a fic I'm working on, and I think your post offers some pointers where else to look. I found Horowitz's book somewhat lacking. It made an interesting read, but imo talked too much about prions and too little about sound.

Right. Off to search for the guidonian hand. Thank you!
