@stuartk,
I like a lot of ideas in the youtube you posted. I think there is no question that music affects our emotions and moods. I have no idea what it means to affect our DNA. Although, I think that since I've begun listening to music all morning and early afternoon, I have become more "mellow" and accepting. I don't get stressed out the way I used to.
As for your series of notes, I don't have an instrument to play them and I can't imagine them in my head. Maybe you'll play with them on your guitar? It seems like the Mhiz posted on the youtube were all mid-bass?
As for patterning in general, I did a lot of reading about fractals and complexity a number of years ago. I've also read some interesting books on the evolution of the universe. The British physicist Paul Davies has written about the universe and God. I read a book about the Gaia Theory by James Lovelock many years ago. He talks about the universe and the earth being living beings. Mathematical fractals correspond to the shapes of leaves and other natural occurrences. An artist friend talked to me about some studies that found fractals in Jackson Pollack's art.
I often wonder what the earliest music must have sounded like. I assume it had a strong beat and the melody from a flute or whatever was less important than it is today. Music is the only art that exists in time, as @mahgister has talked about, and I have a feeling that the beats in time are fundamental to any human music.
Thank you for the list. I'll listen to the ladies later. I've been listening to Robyn as I write this because it's late in the day and I need a kick in the ass. I, too, love the female voice. Maybe I'll post some youtube examples later.
