I've shared this true anecdote a dozen times and I don't remember anyone ever explaining why a clear 440 Hz tone caused such an unusual and un-cat-like reaction in Kali. I decided today to record the story which I now share here.
Cats and harmonics… Makes me realize that the frequencies we identify as notes aren't arbitrary assignments of sounds and letters. Singing in tune pushed some kind of button that domestication can't explain. Can you?
