Yes, it's one of those subjects that can be simple i.e. this is a harmonic & you play it here, but also be complicated when you first delve into the reasons why.
For most visiting this site they will just want to know how to play them & not so much why it all happens & Kirk's lessons get them started.
Actually what is above is quite simple, we could start discussing how there are many other harmonics on the guitar, or how Pythagoras used completely different scales to what we use today (not based on the same 12 notes we have) etc.. but that's another story. But we live post Bach & have Equal temperament, so we should just be happy that we have what we have & enjoy making music with it, because music is all about enjoying yourself!
