From TED, again. Margaret McIntyre referenced this in a comment, but it is too good to be buried there. Here is a glorious example of what our friend Fernando Flores called the difference between listening — the act of interpretive attunement to the concerns of another human being — and hearing — the mechanics of receiving potentially meaningful signals of one sort or another.
“In this soaring demonstration, deaf percussionist Evelyn Glennie leads the audience through an exploration of music not as notes on a page, but as an expression of the human experience. Playing with sensitivity and nuance informed by a soul-deep understanding of and connection to music, she talks about a music that is more than sound waves perceived by the human ear. She illustrates a richer picture that begins with listening to yourself, and includes emotion and intent as well as the complex role of physical spaces — instrument, concert hall and even the bones and body cavities of musician and listener alike.” (Quoted from the TED introduction to the event.)
