re: Thr harmony of nature
Marcia,
Way back in 1976, when I was a student, I went to see a concert given by the violonist Lola Bobesco (who died last week at 83).
One of the airs she played was Bach's Partita nr 3
I don't remember if it struck me at the moment, but I very shortly after found out the very music she played solo with her violin, was recorded to be sent into space on that golden record aboard the Voyager spacecrafts.
(I'm now playing Sagan's Cosmos record where you can find Bach's music.
