Even if we assume a non flexing support rod, you'd need to apply torque to the axle to move the object. The energy required to move the object wouldn't change, so you'd be looking at infinite torque necessary to turn the axle.

One per state probably.

I thought it was the Matterhorn.

Actually, harmonies and melodies do have math in them. There are specific frequency ratios present in those intervals, such that the peaks intermittently line up. This is why it sounds good to us, and I think they'd hear that too.

As such, I recommend Canon in D. It starts simple, one note at a time, and adds in complexity little by little. I think it an excellent option for an introduction to human music.

The other that could go with it would be somewhere over the rainbow, sung by Iz.

Super cool when you get to see them. Dunno what causes it but I've seen a couple in my life.
