A fellow writer friend, Cassandra L Shaw, shared this video. The visualizations of bird sounds.
It reminded me of another philosopher, musician and writer David Rothernburg. he’s written some interesting books, one is Why do Birds Sing. There is a Cd where he plays along with the birds on his clarinet. you can listen to some samples on amazon HERE
He says that to understand bird song you need the knowledge of the scientist the poet and the musician.
