Music is so important to our enjoyment and fulfillment in life. I don't listen to music as much as I did when I was younger. I had a reel to reel tape deck that seemed to always be playing then. I was reminded of this last night by some music, though it was not of human origin. I was sitting on my deck at the top of a hill listening to the hundreds of doves in this neighborhood sing their evening songs. They put on quite a performance and made me think that music might also be important to species we consider to be lower on the scale of evolution.
