[tuning] well.. not really tuning...

I figured there were a lot of other musicians here, and frankly I just didnt
know where else to turn to. The source of all information and goodness,
creator of the universe and master of all, Google did not yield any answers.
So basically my Q is very simple, what musical forms are most used in
national anthems? i can find... nothing about it. To say nothing of harmonies
and such. anyone, anyone?
