To me, it's fascinating that drums with a circular face, produce overtones, not harmonics.  Overtones do not have to be integral multiples of the fundamental.  They can be slightly different.  This is unique versus many musical instruments.

If anybody cares, this is a good explanation:

I should admit that I don't appreciate drums in music.  But, their physics of function is fascinating.

Me thinks Nigel is a bit of a weirdo.  I wonder how much those robot arms are worth.

You say that like being a weirdo is a bad thing! 

Talk about being dragged down the rabbit hole - what a trip!
