Sorry to ask you this (also because it is a cliche), but have a listen with your mind's ear: nails on a chalk board; losing control of your fork and knife on a plate. Ok now try this: a sharpened 2HB pencil writing on good paper with some tooth to it; a whispered conversation; keys clicking steadily on a keyboard; a thick needle puncturing felt. These are some of the sounds that float the ASMR (Autonomous Sensory Meridian Response) folks to the moon. There's the other kind of frisson: a turn of phrase in music that reminds us that we are spirits wrapped in skin having a human experience. Some surefire reminders for me are Benjamin Britten's Cello Suites (72, 80, 87).
