When I tried to take a nap this afternoon, all I could think about was whether the cuckoo sound is part of a major chord or a minor chord. Then I thought of the overtone series and decided that if we're as much a part of the natural world as I think we are, it must be a the top of a major chord. I have never completely understood the overtone series, but from what I understand it would go (1) Fundamental (2) Up a fifth (3) Up a fourth (4) Up a major third, etc. Without taking it any further, you would have, for example, C, up to G, up to C, up to E, which of course would describe a major chord. I think the next note in the series is an E-flat up nearly an octave and thus a minor chord. So the children are probably taking the chord root for granted when they sing nyah nyah-nyah nyah nyah on a minor third.

I picture a string vibrating its full length (the fundamental), then from center to end (octave), but I'm not very clear on where it goes from there (where the nodes are). Maybe you know, since you play guitar.

Now the part in your note about God I'm going to have to read several more times before I can begin to understand it, but even without fully getting it, I think it is just wonderful.
