"Early jazz pioneer Jelly Roll Morton, whose own name was a euphemism for
sex, first developed his own style playing piano in these ‘sporting
houses’ and to get extra tips he’d peek at a prostitute and her client
through a peephole and time his playing with the pace of their revels."
I'm not much of a jazz fan, but I love attempts to suss out the origins of human interest and passion and seriousness.
